EMP Brushless Electric Fan
TK1 coolers feature an EMP electric fan. Fans are available with or without an integrated controller. All EMP fans are brushless, controllable, reversible, and built from a cast aluminum shroud that can withstand even the harshest environments. Click here to learn more about EMP's fans.
System Controller Included
Temperature controlled TK1 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 TK1 coolers are fabricated from an aluminum alloy that has been proven by numerous tests to be superior to copper-brass construction in durability and efficiency, while also weighing less.
The fan on TK1 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.
Fans on temperature controlled TK1 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.
TK1 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. TK1 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 TK1 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.
TK1 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).
Note: J1939 CAN integrated FiL-11 fans available Q1 2017.
