Constructed of carbon steel, it bolts to the exchanger and gives a stable mounting base for installation into a hydraulic power unit or process cooling skid.
- [Flexible Metal Hose](https://www.thermaltransfer.com/product/flexible-metal-hose-2/): The Flexible Metal Hose is a vibration-isolation connector designed to protect equipment from the damaging vibration, noise, and thermal expansion transmitted by pumps and compressors. Installed between the vibration source and related downstream equipment — such as a heat exchanger, cooler, or rigid piping — it flexes to absorb movement and thermal growth that would otherwise stress joints, loosen fittings, and shorten equipment life.
- [Automatic Float Drains FD-25 and FD-50](https://www.thermaltransfer.com/product/automatic-float-drains-fd-25-and-fd-50/): The Thermal Transfer Products Float Drain automatically discharges the liquid condensate collected by a compressed-air moisture separator, keeping accumulated water from carrying downstream into tools, piping, and processes. A float mechanism opens the drain as water builds up and closes it once cleared, so condensate is removed continuously without manual intervention or wasted air.
- [M/S-2600-4F Model](https://www.thermaltransfer.com/product/m-s-2600-4f-model/): These separators have 1500 through 3500 SCFM capacity. Consult factory for details on larger models through 16,000 SCFM.
- [S-200 thru S-1700 Models](https://www.thermaltransfer.com/product/s-200-thru-s-1700-models/): The Thermal Transfer Products Moisture Separator removes condensed water and contaminants from compressed air after it leaves an aftercooler, delivering cleaner, drier air and protecting downstream tools, piping, dryers, and processes. Its unique high-efficiency design maintains separation performance across a wide range of flow rates, so a single unit handles varying demand without losing effectiveness.
- [S-50 and S-100 Models](https://www.thermaltransfer.com/product/s-50-and-s-100-models/): The Moisture Separator is a compressed-air accessory that removes condensed water and contaminants from the air stream after it leaves an aftercooler. When an aftercooler cools hot compressed air, moisture condenses out; the separator collects that liquid and drains it away, delivering cleaner, drier air and protecting downstream tools, piping, dryers, and processes from water damage and corrosion. It's the recommended final step in any compressed-air cooling package.
- [Electric Temp Sensor](https://www.thermaltransfer.com/product/electric-temp-sensor/): The Thermal Transfer Products dual-output temperature sensor is an electronic temperature switch that provides two independent switching outputs from a single unit, over a wide measuring range of -13 to 284 °F (-25 to 140 °C). It generates one normally open (NO) and one normally closed (NC) signal, each with a separately adjustable switch point — so a single sensor can trigger two actions at two different temperatures, such as starting a cooling fan at one setpoint and an alarm or second stage at another.
- [Electronic Temp Sensor](https://www.thermaltransfer.com/product/electronic-temperature-sensor/): The immersion thermostat is a simple, low-cost temperature sensor for measuring temperature on a primary heating-pipe circuit. It's particularly suited to controlling automatic adjustment (variable-speed) pumps, switching or modulating pump operation based on circuit temperature to maintain efficient, stable system performance.
- [Single Set Point Switch](https://www.thermaltransfer.com/product/single-set-point-switch/): The Thermal Transfer Products Single Set Point Switch is a temperature-actuated electrical switch used to control a cooling fan, alarm, or other device based on fluid temperature. Its super-sensitive probe senses the oil or coolant temperature and, on temperature rise, closes its electrical contacts at a preset set point — switching the fan on for cooling and off again as the fluid cools, without any separate controller.
- [Electronic Temperature Controller (DC) Control & Bulb Well Assembly (AC)](https://www.thermaltransfer.com/product/electronic-temperature-controller-dc-control-bulb-well-assembly-ac/): The Electronic Temperature Control & Bulb Well Assembly (AC) provides accurate, adjustable temperature control for cooling (or heating) systems, pairing electronic precision with remote-sensing capability. It's used to switch a fan, pump, or other device based on fluid temperature — for example, cycling a cooler's AC fan to hold a target oil temperature.
- [Thermal Bypass](https://www.thermaltransfer.com/product/thermal-bypass/): The Thermal Transfer Products Thermal Bypass Valve is a return-line temperature-control valve for hydraulic and hydrostatic drive circuits that require fast warm-up, controlled fluid temperature, and low return-line back pressure. Installed in the return line of a hydraulic circuit that uses an oil cooler, it automatically modulates fluid temperature by shifting return-line flow through the cooler once the oil is warm, or bypassing it directly to the reservoir during cold start-up.
- [Three-Way Thermostatic Valves](https://www.thermaltransfer.com/product/three-way-thermostatic-valves-2/): Our heavy duty thermostatic valves operate in a wide range of temperatures and in any position. Valves are compact, self-contained and tamper-proof. Acceptable for oil or water service and available with ½", ¾", 1", 1½" & 2" NPT Ports.
- [Forged Brass Y-Strainer](https://www.thermaltransfer.com/product/forged-brass-y-strainer/): The Y-Strainer is a heavy-duty inline pipeline strainer that protects heat exchangers, temperature-control valves, pumps, and other equipment from pipe scale, weld slag, and debris carried in the fluid line. Installed upstream of the component it protects, it captures particulate in a stainless steel screen that's easily removed and cleaned through the screwed cap — inexpensive insurance against fouling and premature wear.
- [S-BAR, T-BAR, P-BAR Modules](https://www.thermaltransfer.com/product/s-bar-t-bar-p-bar-modules/): Our manufactured custom OE engine cooling modules for small gasoline engines to large-horsepower turbo diesel applications. Your choice of a variety of materials and core types (S-BAR, T-BAR, or P-BAR) offers design flexibility for high-performing radiators, CAC’s, or oil cooling. Full system modeling and validation of cooling modules is provided.
- [M Series](https://www.thermaltransfer.com/product/m-series-2/): The Thermal Transfer Products M Series is a rugged, compact belt-guard compressed air aftercooler for reciprocating (piston) compressors. It mounts directly to the compressor's belt guard and uses the free airflow generated by the belt-driven flywheel to cool the compressed air — so no separate fan motor, electrical connection, or cooling water is required. That makes it one of the simplest, lowest-cost ways to add aftercooling to a belt-driven compressor.
- [BGA Series](https://www.thermaltransfer.com/product/bga-series/): The Thermal Transfer Products BGA Series is a rugged, compact compressed air aftercooler built on a brazed aluminum bar-and-plate core for high performance and excellent heat recovery. It's designed to mount directly to the belt guard of a reciprocating (piston) air compressor, using the free airflow from the compressor's belt-driven flywheel fan to cool the compressed air — so no separate fan or fan motor is required. That makes it a simple, low-cost, energy-free way to add aftercooling to a reciprocating compressor.
- [AHP/AHPH Series](https://www.thermaltransfer.com/product/ahp-ahph-series/): The Thermal Transfer Products AHP/AHPH Series is a high-performance air-cooled aftercooler purpose-built for cooling compressed air.

Both models carry a durable black powder-coat finish and are backed by downloadable 3D CAD models, technical documentation, and application engineering support to simplify OEM integration.
- [ACOC/ACOCH Series](https://www.thermaltransfer.com/product/acoc-acoch-series/): The Thermal Transfer Products ACOC/ACOCH Series is a combination air-cooled oil cooler and compressed air aftercooler engineered specifically for rotary screw air compressors. In a single, compact, side-by-side brazed aluminum bar-and-plate core, it handles two jobs at once — cooling compressor lubricating oil and cooling compressed air — so you don't need separate heat exchangers.
- [AB Series](https://www.thermaltransfer.com/product/ab-series/): The Thermal Transfer Products AB Series is a high-performance, water-cooled compressed air aftercooler that uses supplied cooling water to cool compressed air or gas discharged from piston (reciprocating) compressors. By dropping the temperature of the hot discharge air, it condenses moisture out of the compressed air stream and protects downstream piping, tools, and dryers.
- [SSC Series](https://www.thermaltransfer.com/product/ssc-series/): The Thermal Transfer Products SSC Series is an all-316 stainless steel shell and tube heat exchanger for oil-to-water and water-to-water cooling in demanding environments. Every wetted component — tubes, tubesheets, shell, shell connections, baffles, and end bonnets — is 316/316L stainless steel, making the SSC the right choice where corrosive process fluids, saltwater, or poor-quality cooling water would quickly degrade a standard steel or brass cooler.
- [EKT Series](https://www.thermaltransfer.com/product/ekt-series/): The Thermal Transfer Products EKT Series is a reservoir-mounted, water-cooled finned-tube oil cooler for hydraulic power units. It's a tank-flange version of the EK "Green Cooler" — the finned-tube bundle mounts through a flange directly into the hydraulic reservoir, so the cooler sits inside the tank instead of in an external cooling line. That eliminates external plumbing and mounting hardware, saves space, and simplifies integration into the hydraulic power unit.
- [EC Series](https://www.thermaltransfer.com/product/ec-series/): The Thermal Transfer Products EC Series — the "Green Cooler" — is a high-capacity, water-cooled finned-tube shell and tube heat exchanger for hydraulic oil cooling. It's the larger, higher-performance version of the EK Series, sharing the same finned-tube bundle core design but scaled up to handle flows up to 250 GPM for demanding, high-flow applications.
- [COLW Series](https://www.thermaltransfer.com/product/colw-series/): The Thermal Transfer Products COLW Series is a water-cooled off-line fluid conditioning system for independent cooling and filtering of hydraulic and lube system oils. It runs as a self-contained loop — often called an off-line or "kidney loop" conditioning circuit — driven by reliable, high-performing, low-noise screw pump technology, so it conditions the reservoir continuously without depending on the main system's flow.
- [CA Series](https://www.thermaltransfer.com/product/ca-series/): The Thermal Transfer Products CA Series is a bare-bundle, fixed-tubesheet shell and tube heat exchanger for water-to-oil cooling of hydraulic systems.

- [BPW Series](https://www.thermaltransfer.com/product/bpw-series/): The Thermal Transfer Products BPW Series is a made-to-order brazed plate heat exchanger for high-efficiency liquid cooling, engineered to your specific application. Where the standard BPSW Series offers a fixed range of off-the-shelf models, the BPW is the build-to-order version — you specify the plate size, number of plates, port configuration, and material options to match your exact flow, heat load, and approach temperature.
- [A Series](https://www.thermaltransfer.com/product/a-series/): The Thermal Transfer Products A/SA Series is a bare-tube-bundle shell and tube heat exchanger for water-to-oil cooling, versatile enough to accommodate a wide range of application requirements. It was developed as a direct interchange for ITT/Standard Xchange (formerly Standard-Xchange / ITT Standard) shell and tube coolers, making it a straightforward replacement in existing installations built around those units.
- [RM Series](https://www.thermaltransfer.com/product/fluid-air-rm/): The Thermal Transfer Products Industrial RM Series is a compact, low-cost, low-flow air-cooled oil cooler designed specifically for hydraulic case-drain cooling. It mounts on the rear of an existing TEFC (totally enclosed fan-cooled) electric motor and uses that motor's own fan airflow to cool the oil — so it needs no fan or motor of its own, saving cost, space, and installation effort.
- [AOC Series – Mobile](https://www.thermaltransfer.com/product/aoc-series-mobile/): The Thermal Transfer Products Mobile AOC Series is a cost-effective air-cooled hydraulic oil cooler built for mobile and off-highway equipment. It uses a copper-tube, aluminum-fin core with a high-performance air-side fin design, and is offered with 12- or 24-volt DC fans or a long-life hydraulic fan motor drive, in single- or dual-fan configurations, making it ideal for low-flow power unit applications.
- [AOC Series – Industrial](https://www.thermaltransfer.com/product/aoc-series-industrial/): The Thermal Transfer Products Industrial AOC Series is a low-cost air-cooled hydraulic oil cooler built with a copper-tube, aluminum-fin core and an AC fan drive. It's designed for basic hydraulic power unit applications and lower flow rates, cooling hydraulic oil with ambient air where an economical, industrial-duty cooler is the priority.
- [Modulating Water Valve](https://www.thermaltransfer.com/product/modulating-water-valve/): The Thermal Transfer Products modulating water regulating valve automatically controls the flow of cooling water to a water-cooled heat exchanger to maintain a desired exiting oil temperature. As the oil temperature rises, the valve's sensing bulb opens the valve to admit more cooling water; as it falls, the valve throttles back — holding a stable oil outlet temperature without wasting water. Because it's thermally self-actuated, no external power source, air supply, or control wiring is required.
- [COL Series](https://www.thermaltransfer.com/product/col-series/): The Thermal Transfer Products COL Series is an air-cooled off-line fluid conditioning system that provides independent cooling and filtering of system oils. Built around reliable, high-performing screw pump technology, it runs as a self-contained loop — often called an off-line or "kidney loop" conditioning circuit — so it cools and filters the reservoir continuously without depending on the main system's flow. That makes it ideal for large hydraulic reservoirs, lube systems, and gearboxes where consistent oil temperature and cleanliness are critical.
- [AOF Series](https://www.thermaltransfer.com/product/aof-series/): The Thermal Transfer Products Industrial AOF Series is an air-cooled hydraulic oil cooler built with a copper-tube, aluminum-fin core and an AC fan drive, distinguished by a replaceable air-side filter that protects the heat exchanger in adverse environments. In dusty, dirty, or debris-heavy settings, the filter keeps the fins from clogging and preserves cooling performance — making the AOF the filtered version of TTP's AO Series for the same medium-flow, moderate-heat-removal duty.
- [AO Series](https://www.thermaltransfer.com/product/ao-series/): The Thermal Transfer Products Industrial AO Series is an air-cooled hydraulic oil cooler built with a copper-tube, aluminum-fin core and an AC fan drive.

- [PF Series](https://www.thermaltransfer.com/product/pf-series/): The PF Series is a high-performing gasketed plate style heat exchanger.  Able to handle large volumetric flows with low temperature drops, the design features large heat exchanging surfaces in a very compact, space-saving frame.  The units can be readily expanded or reduced to accommodate changes in performance.  This cost effective series is ideal for oil-to-water applications.  Titanium plates are available for salt water service.
- [B Series Hydraulic Oil Coolers](https://www.thermaltransfer.com/product/b-series/): The Thermal Transfer Products B/SB Series is a bare-tube-bundle, fixed-tube-sheet shell and tube heat exchanger designed for water-to-oil cooling. It's used to cool hydraulic oil in a wide range of industrial systems — hydraulic power units, injection molding machines, test benches, and general process cooling — and its highly standardized design keeps cost down while still accommodating multiple application requirements.
- [HC Series](https://www.thermaltransfer.com/product/hc-series/): The Thermal Transfer Products HC Series is a bare-bundle, fixed-tubesheet shell and tube heat exchanger that uses water to cool hydraulic oil, compressor lube oil, and compressed air. Its highly standardized design makes it one of the most cost-effective water-cooled heat exchangers available, and it remains an industry standard for value and long-term reliability.
- [DH Series](https://www.thermaltransfer.com/product/dh-series/): The Thermal Transfer Products DH Series is a low-cost, high-performance mobile cooler core built for radiator face-mount fuel and transmission cooling, as well as hydraulic oil cooling. Because it's a core (no integral fan), it mounts against the vehicle's radiator or another airflow source and relies on that existing airflow — an economical, space-saving way to add auxiliary cooling to mobile equipment.
- [M Series Hydraulic Oil Cooler](https://www.thermaltransfer.com/product/m-series/): The Thermal Transfer Products Mobile M Series is a heavy-duty, copper-tube/aluminum-fin cooler core built for mobile and off-highway equipment — one of the most rugged and robust heat exchangers in the TTP family. As a core without its own fan, it's designed to face-mount to a radiator or integrate within an engine cooling module, using existing engine airflow to cool the fluid. That makes it a compact, cost-effective way to add oil, fuel, or transmission cooling to a mobile machine.
- [DF Series](https://www.thermaltransfer.com/product/df-series/): The Thermal Transfer Products Mobile DF Series is a rugged air-cooled hydraulic oil cooler engineered for very demanding mobile and off-highway applications. Its robust design features steel tanks and damage-resistant steel fins — rather than the more delicate aluminum fins used on lighter-duty coolers — so it withstands impact, flying debris, vibration, and rough handling in the field while delivering moderate flow rates and high heat removal.
- [MF Series](https://www.thermaltransfer.com/product/mf-series/): The Thermal Transfer Products Mobile MF Series is a self-contained, air-cooled hydraulic oil cooler for mobile equipment — the rugged M Series core with an integral fan drive added, so it doesn't depend on radiator or engine airflow. You can specify a low-amp-draw DC motor or a long-life hydraulic fan motor to match the power available on the machine.
- [AOVH Series](https://www.thermaltransfer.com/product/aovh-series/): The Thermal Transfer Products Industrial AOVH Series is a high-performance air-cooled hydraulic oil cooler built with a copper-tube, aluminum-fin core. As the high-capacity version of TTP's AO Series, it delivers high heat rejection and low pressure drop for high-flow applications, using a double-core, AC-fan-driven design in a compact footprint. Its High-Low Turbulator design is what yields high flow capacity with low flow pressure, making it well suited to demanding, continuous-duty cooling.
- [AOHM/AOVHM Series](https://www.thermaltransfer.com/product/aohm-aovhm-series/): The Thermal Transfer Products AOHM and AOVHM Series are mobile air-cooled hydraulic oil coolers built with a copper-tube, aluminum-fin core and driven by a long-life hydraulic motor — ideal for off-highway and mobile equipment where electric fan power isn't practical.

- [OCA Series](https://www.thermaltransfer.com/product/oca-series/): The Thermal Transfer Products OCA Series is a high-performance, forced-air oil cooler engineered for high heat rejection, high-viscosity fluids, and rough operating environments. It's built around TTP's patented T-BAR™ solid extruded-tube core — where other TTP lines offer T-BAR™ as an option, the OCA is designed around it, giving the series exceptional durability under high shock loads and high pressure spikes while reducing pressure drop with thick, viscous oils.
- [BOL Series](https://www.thermaltransfer.com/product/bol-series/): The Thermal Transfer Products BOL/BOLR Series is an industrial air-cooled hydraulic oil cooler built on a brazed aluminum bar-and-plate core. It delivers outstanding heat dissipation for extreme heat loads in a rugged, lightweight, and compact package, making it well suited to hydraulic power units, hydraulic presses and industrial machinery, and gearbox and lube-oil cooling circuits where high thermal loads run continuously.
- [AOL Series](https://www.thermaltransfer.com/product/aol-series-2/): The Thermal Transfer Products AOL Series is an industrial air-cooled oil cooler built on a rugged brazed aluminum bar-and-plate core, engineered for outstanding heat dissipation under extreme heat loads in a lightweight, compact package. It uses forced ambient air to cool compressor lube oil, rotary screw compressor oil, and gearbox oils — and it's an excellent choice for converting medium-to-large water-cooled compressors to air-cooled cooling, eliminating water and sewer costs.
