Davies Craig Digital Thermo Thermatic Radiator Fan Controller Switch with 1/4" NPT Thermal Sensor Kit DC 0445

A fiercely proud Australian company, Davies Craig has gone to great lengths to keep the manufacture of their products at home in Melbourne Victoria, utilizing a local workforce. Davies Craig was founded by engineers Daryl Davies and Bill Craig, has revolutionized automotive cooling with their innovative products. In 1971, they introduced the Thermatic Fan, the first electric alternative to belt-driven fans, setting a new industry standard. In 1999, they launched the EWP80, the first Electric Water Pump, further enhancing engine efficiency and gaining adoption by major European manufacturers. Known for their commitment to technology, service, and quality, Davies Craig offers a comprehensive range of high-flow electric water pumps, fans, and digital controllers. Their dedication to customer service, along with their ISO 9001 certification, has solidified their reputation as a global leader in automotive cooling solutions.

This kit comes with two sensors offering a host of different installation options for coolant temperature sensing.

Sensor 1: Temperature Probe (Air or Coolant  Fitment)

It senses air temperature as it passes through the radiator with the sensor placed in the radiator fin section or the sensor can also be placed directly into the coolant system in combination with a Temperature Sensor Adaptor Kit.

Sensor 2: 1/4 NPT Thermal Sensor Kit (Coolant or Oil Fitment)

The Thermal Sensor can be placed into the thermostat housing, engine block, or directly into the radiator. If you would like to install this sensor in the top radiator hose, It can also be used with Temperature Sensor Adaptor Kit.
 

The switch can run 1 or 2 fans and be used for 12 or 24 volt applications. It has an adjustable temperature range of 40ºC to 110ºC (104ºF to 230ºF) which can show Centigrade or Fahrenheit.

• Fan #1 will start once the temperature reaches the set temperature.
• Fan #2 (if applicable) will start operation 10 seconds after fan #1 starts. 

The fan/s will operate until the temperature falls by 5°C below the set temperature.

Sensor Wire length:

• 142cm in total (Wire from switch 112cm plus sensor connector 30cm)
• Post 15-Dec-2021 = 320cm total (Wire from switch 290cm plus sensor connector 30cm)

*The sensor wire has been increased to 320cm from the 15-Dec-2021, batch date 2021

IP66 Rated:

• Protected from total dust ingress
