Automotive cooling has been at the heart of Davies, Caig’s business since 1972

It all began with the creation of the Thermatic Electric Cooling Fans, and then in the late 1990s, Davies, Craig conceived the innovative remote-mount Electric Water Pump (EWP). Most significant too was the introduction of the Davies, Craig EWP Controller.
Sophisticated new cooling systems enable an internal combustion engine to operate at higher temperatures with far greater efficiency.
These innovations demand more precise thermal management for internal combustion and hybrid power train systems.
This is achieved by controlling and varying the coolant flow commensurate with engine temperatures, totally independent of the engine’s speed.
Australian manufacturer Davies, Craig says this process was made possible by the introduction of the initial Davies, Craig EWP Controller, launched in 1999.
Since then, this unique Controller has advanced to encompass digital technology and now the patented LCD EWP/Fan Digital Controller monitors and manages the entire cooling system for both 12V and 24V electrical systems.
The introduction of the display screen along with several new push-button features now also vastly enhances information available in demanding highway and motor sport applications.
The LCD EWP/Fan Digital Controller Kit (Part #8002) will also manage other billeted-type electric water pumps.
Importantly, it can also provide heat soak protection and continues coolant circulation and electric cooling fan air flow for a period after engine shutdown.
These advantages will, no doubt, become even more crucial as environmental regulations continue to increase, along with consumer demands for more fuel-efficient, higher horsepower vehicles.
Davies, Craig says there are some significant horsepower and torque gains should the mechanical water pump and mechanical fan be removed and replaced with a Davies, Craig EWP Electric Water Pump Combo Kit, which includes the Digital Controller and Thermatic Electric Cooling Fan.
Regardless of the engine’s cubic capacity, many owners have either removed or blanked off the mechanical water pump or just simply removed the impellor/s. Either way, the mechanical water pump will operate in unison with any model EWP, says Davies, Craig.
Horsepower gain, timelier engine warm-up and better throttle response will be achieved if you remove the impellor/s or the water pump entirely, says Davies, Craig, which has just expanded its Electric Water Pump (EWP) range by adding two alloy EWP80 Electric Water Pumps delivering 90 l/min.
Davies, Craig says these two high tech products offer unsurpassed cooling efficiency for most engines up to two litres.
Further, the other Davies, Craig EWP models; EWP115, EWP140 and EWP150, are lightweight and deliver excellent flow rates.
The unique compact design allows for simple remote mounting into a tight engine bay on the bottom radiator hose.
Variable inlet and outlet adaptors are available. With efficient low current draw ‘pancake’ motors built into the pump body, this offers the EWP motor an acceptable operating environment as the engine’s coolant passes smoothly through the pump’s volute chamber, thus producing excellent air-free coolant flow.
The patented Davies Craig LCD EWP/Fan Digital Controller will manage the operation and performance of both the Electric Water Pump and Electric Cooling Fan/s, becoming the engine’s new ‘thermostat’ and will automatically turn on the fan at 3°C above the set/targeted temperature, which is normally set at the manufacturer’s thermostat temperature for efficient engine operation.
The entire range of Davies Craig Electric Water Pump (EWP) Combo Packs and the Thermatic Electric Cooling Fans are available with simple, do-it-yourself ‘plug and play’ with a comprehensive booklet of installation instructions.
