Digital Controller

EWP & FAN DIGITAL CONTROLLER - PART No: 8020  (INSTRUCTION SHEET)
The updated Digital Controller how has two specific functions. This unique Controller will now manage the operation of the EWP® by varying the speed of the EWP® in response to the temperature of the engine and manage control of your electric engine fan. The Controller has a push-button on the facia panel that offers 5 target temperatures, 75ºC, 80ºC, 85ºC, 90ºC & 95ºC. Generally, higher engine temperature will offer improved fuel efficiency and lower engine temperature more power. The Digital Controller will now operate the engine’s electric fan automatically once the engine has reached +3c above the target temperature. A significant benefit too is the Controller allows the EWP® to run on after ignition shutdown to reduce heat soak. It is recommended that engine operational temperatures be checked with manufacturer.

In combination with a Davies, Craig Thermatic Fan®,  the temperature of the whole cooling system can be customised to suit your requirements.

Thermal Switches

A Thermal Switch is a device which senses the temperature of the radiator and turns on the electric fan when cooling is needed. The Thermal Switch is adjustable over a wide range of temperatures by turning an adjustable screw located on the controller.

MECHANICAL THERMAL SWITCH - PART No: 0401 & 0404(with relay) (INSTRUCTION SHEET)
The Electronic Thermal Switch Kit has an adjustable temperature range of 40ºC to 99ºC (104ºF to 210º F). The Electronic Thermal Switch, relay and wiring loom are assembled and pre-connected ready for installation. This switch is operated thermally and also when the air conditioning is in operation. The Electronic Thermal Switch has the advantage over the Mechanical Thermal Switch in that the probe is designed to be placed between the radiator fins and accurately sensors the air temperature.

ELECTRONIC THERMAL SWITCH (12V ONLY) - PART No: 0402 (INSTRUCTION SHEET)
The Electronic Thermal Switch Kit has an adjustable temperature range of 40ºC to 99ºC (104ºF to 210ºF). The Electronic Thermal Switch, relay and wiring loom are assembled and pre-connected ready for installation. This switch is operated thermally and also when the air conditioning is in operation. The Electronic Thermal Switch has the advantage over the Mechanical Thermal Switch in that the probe is designed to be placed between the radiator fins and accurately senses the air temperature.

TEMPERATURE SENSOR ADAPTOR KIT - PART No: 0409 (INSTRUCTION SHEET)
Now there is no need to squeeze the probe of the Mechanical Thermal Switch or EWP Controller between the radiator inlet and radiator hose. This simple and economical Adaptor Kit allows easy fitting directly into the radiator hose. Just fit probe into compression fitting, remove about 17mm of radiator hose, fit adaptor between each end of hose, secure hose clamps and the job is done. The kit comes with everything you need for a watertight and effective installation. We even supply rubber sleeves to enable fitment to radiator hose sizes from 32 to 40 mm diameter.
