Smart Flow® Water/Glycol Cooling Systems

Product Features

• EMP Brushless Electric Fan

  All of our TK series coolers feature EMP fans. EMP’s fans are brushless, controllable, reversible, and built from a cast aluminum shroud that can withstand even the harshest environments.

  Fans on temperature controlled TK models are speed controlled by the system controller based on fluid temperature feedback. This allows for optimal thermal management and little fluid temperature variation, while also helping to prevent heat exchanger clogging in dirty environments. Fan speed on PWM and J1939 CAN controlled models can be configured by the customer.

• System Controller Included

  Temperature controlled TK coolers include an EMP CM20 controller, while the on/off, CAN, and PWM controlled versions feature a C20 controller or an integrated fan controller. The controller receives input from sensors or the vehicle to determine precise cooling demand, and drives the fan accordingly. CM20 and C20 controllers also provide full diagnostic capability.

• Aluminum Heat Exchanger

  Heat exchangers on TK coolers are of bar/plate construction and fabricated from an aluminum alloy that has been proven through stringent testing to be superior to copper-brass construction in durability and efficiency, while also weighing less.

• Intergrated Wiring Harness

  Temperature controlled TK models contain an integrated wiring harness assembly that will not break down or degrade when exposed to petroleum based fluids and glycol. The harness is built using connectors and interface terminals that are IP69k rated waterproof and dustproof.

• Reversible

  The fan(s) on TK coolers can be reversed periodically as a part of routine vehicle maintenance. This helps keep the heat exchanger cooling fins free of debris and functioning properly. Fan reverse can be controlled by a CAN/J1939 command, as a timed event, or by ignition on.

• Variable Speed

  Fans on temperature controlled TK coolers are speed controlled by the CM20 controller based on coolant temperature feedback. This allows for optimal thermal management and little fluid temperature variation, while also helping to prevent heat exchanger clogging in dirty environments. Fan speed on PWM and CAN controlled models can be configured by the customer.

• Configurable

  TK coolers come in both 12 and 24-volt versions to allow for easy installation on most vehicles by eliminating the need for an auxiliary power circuit. Units are also available in both pusher and puller configurations to maximize mounting location adaptability. Control strategy and fan speed can be configured as variable-speed temperature control, custom-speed PWM or CAN control, or single-speed on/off. A WP29 water pump and/or 2-quart degas bottle are available as optional accessories.

• Increased Available Engine Horsepower

  Any engine power used for cooling is directly subtracted from the horsepower available for driving the wheels, hydraulics, PTOs, etc. TK electric coolers manage coolant temperature while consuming much less power than a system cooled by a belt-driven fan or hydraulic fan.

• Optimized Fluid Temperature

  Temperature controlled TK coolers receive coolant temperature feedback from a thermistor sensor and drive the fans as necessary to maintain an optimal coolant temperature. This eliminates overheating and overcooling due to changes in ambient temperature and cooling demand.

• Diagnostics

  EMP-Link and J1939 CAN versions allow two-way communication to support diagnostics. J1939 CAN communications support J1939 messages defined for Secondary OBD Devices.

• Communication Protocols

  TK can be controlled through the following communication protocols: On-Off, J1939 CAN, PWM , EMP-Link (Proprietary LIN), and Temp Sensor. EMP-Link and J1939 CAN versions allow two-way communication to support diagnostics. J1939 CAN communications support J1939 messages defined for Secondary OBD Devices. PWM version provides tach-out feedback (RPM).
