The Thermal Transfer Products MAGHEX 2 is a compact, programmable fan controller and temperature sensor in a single aluminum housing — a smart, temperature-based controller for oil and coolant fan systems in mobile and industrial applications. It mounts directly to the heat exchanger and provides accurate temperature control by cycling the electric cooling fan to maintain the desired oil temperature.
Combining the sensor and controller in one housing reduces wiring and mechanical installation, and it integrates easily into the MA Series through any SAE #8 or 3/8″ – 1/2″ NPT ports. It creates a simple fan drive circuit with minimal programming, making it a low-cost alternative to complex control systems. The built-in temperature sensor activates the fan based on the current set point, and onboard LEDs indicate oil temperature status — below, at, or 20°F above the set point.
The MAGHEX 2 operates on 12 or 24 volt DC and controls loads up to 60 amps, with ten selectable temperature set points from 100° to 200°F (38° to 93°C). Setup and programming are done with the MAGHEX 2 magnetic wand, which is not required for normal operation. Consult the catalog for additional technical information.

An optional feature for the MAR and BOLR Series – thermal bypass and pressure relief features combined in one valve. Temperature bypass is activated (closes) when oil reaches a defined set point of 110° F and allows full oil flow through the heat exchanger. When the oil is cool, the valve is open to allow a partial flow bypass.
Function
TTP Thermal Bypass Valves ensure precise oil temperature control in hydraulic systems by routing cold oil around the heat exchanger during start up. This prevents overcooling, protects the cooler, and speeds up system warm-up for reliable, efficient operation
Thermostatically activated, these valves route partial, cold oil flow around the heat exchanger to limit backpressure and unwanted cooling of oil during cold start-up situations. When the oil is cold (<110°F, 43°C), the internal valve connection P-T is open directing flow around the cooler with minimum pressure loss and enabling the oil temperature to increase to operating temperature. Once this temperature is reached (>110°F, 43°C), the thermal wax element closes the P-T connection and full flow is directed through the heat exchanger. The integrated pressure relief valve, set at 60 PSI, also helps safeguard the cooler from occasional return-line flow surges.
This Foot Mounting Bracket is an optional accessory for Thermal Transfer Products BPSW and BPW Series brazed plate heat exchangers, providing a simple, secure way to floor- or surface-mount the unit. 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.
The bracket is compatible with all BPSW and BPW brazed plate models except the 8×3 plate size. For the exchangers themselves, see the standard BPSW Series and the made-to-order BPW Series.
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.
The hose itself is corrosion-resistant type 304 stainless steel, so it stands up to demanding fluid and environmental conditions. The connectors are carbon steel Schedule 40 with external NPT threads and hex-nut attachments on both ends for straightforward installation, and the couplings are welded to assure dependable, leak-free operation.
The Flexible Metal Hose is ideal for installation directly on a pump, compressor, or other vibration source — protecting TTP heat exchangers and cooling packages from vibration-induced fatigue. For long service life, it should be installed close to the vibration source and oriented with its length perpendicular to the direction of vibration, without compressing, twisting, or stretching the hose. TTP Application Engineering can help select the right size and length.
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.
Two economical models fit most applications. Both are built with a rugged cast-zinc housing for long service and are equipped with a quick-disconnect bowl that detaches for fast, tool-free cleaning and servicing.
The Float Drain installs on the moisture separator downstream of a compressed-air aftercooler, completing the moisture-removal package alongside TTP’s aftercooler lines (ACOC/ACOCH, AB, BGA, M, and AHP/AHPH). TTP Application Engineering can help match the right drain to your separator and application.
These separators have 1500 through 3500 SCFM capacity. Consult factory for details on larger models through 16,000 SCFM.
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.
Four models are available to fit most applications, together covering a wide SCFM capacity range. Each is built from sturdy, lightweight aluminum for long, dependable service and is epoxy-painted both externally and internally for maximum corrosion protection — important given the wet, condensing environment it operates in. A low differential pressure even at maximum flow ratings keeps energy losses down.
An NPT threaded drain connection lets you install the drain that suits your operation — electronic, manual, or automatic float style. The separator installs inline just downstream of the aftercooler and pairs with TTP’s compressed-air aftercooler lines (ACOC/ACOCH, AB, BGA, M, and AHP/AHPH). TTP Application Engineering can help match the right model and drain to your airflow.
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.
Two models cover different drain needs. One has a built-in automatic float-style drain that discharges collected condensate automatically as it accumulates — ideal for unattended operation. The other has a 1/8″ NPT connection with a manual shut-off valve, for applications where scheduled or manual draining is preferred. Both are built in a rugged cast-zinc housing and equipped with a quick-disconnect bowl for fast, tool-free servicing.
The separator installs inline just downstream of the aftercooler and pairs with TTP’s compressed-air aftercooler lines — the ACOC/ACOCH, AB, BGA, M, and AHP/AHPH Series. TTP Application Engineering can help match the right separator and drain to your airflow and installation.
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.
The sensor has a ¼″ NPT process connection for direct installation in a cooler port or fluid line. Sensor port adapters are available to fit a range of ports, and optional bulb wells (thermowells) allow the sensing element to be immersed in the fluid while isolated from it — protecting the sensor and allowing removal or replacement without draining the system.
Its two-setpoint flexibility makes it well suited to multi-stage fan control, staged cooling, or combined control-plus-alarm functions on TTP coolers and cooling packages. TTP Application Engineering can help configure the setpoints and adapters for your application.
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.
The thermostat measures temperature with a liquid-filled sensing element — a proven, reliable sensing method that needs no external power — and comes complete with a waterproof protection pocket (thermowell) that lets the sensor be immersed directly in the pipe while staying isolated from the fluid for easy service and replacement. Its simple set-up makes it a practical, economical choice for pump and heating-circuit temperature monitoring.
The sensor is ideal for heating and hydronic pipe circuits and for pairing with automatic pumps in cooling and process systems. TTP Application Engineering can help select the correct temperature range and pocket length for your pipe and application.
