Intelligent pump to revolutionise engine cooling
Davies, Craig will launch its patented third-generation EWP electric water pump and electronic smart controller in May 2004.
Automotive pump moves more coolant
Davies Craig has launched a higher-capacity heavy duty automotive electric water pump, the EWP110.
This is achievable because the controller has been digitally configured to give a choice of 75, 80, 85, 90 or 95C engine temperature - selected at the touch of a button.
To miminise the effects of "heat soak" the controller automatically continues to run the EWP after ignition off for a period of 2 minutes or until the engine temperature is 5C below the set temperature, whichever occurs first.
It also boasts a real-time diagnostic facility.
Nearly all cars these days are fitted with an engine cooling thermostat preset to a single temperature.
That figure is a compromise between power and economy but it delivers neither with full efficiency.
Whereas the controller leaves the Davies Craig factory preset to 85C, its button selection system quickly gives the option of 10C either side.
Such an innovative facility has never been offered on a car before anywhere in the world and it enables the driver to set the engine to say 95C at which temperature it gives maximum economy or down to 75C when the cooler running will give maximum power.
"We've had a tremendous response to the release of this Controller with enquiries coming in from world-wide", says Davies Craig's Ray Brown.
"No one has ever seen anything like it and everyone instantly realises exactly the full benefits it offers.
"While it can obviously be left at say 85 degrees while the sophisticated EWP allows quick engine warm up and top management of the car's cooling system, many drivers will prefer to select 95 for an even quicker warm-up and good economy, switching to a cooler engine setting when full power is needed".
"We've put in considerable investment on the production methods that make this controller the top quality that ensures our advanced EWP can show its best.
It's truly world class unit from every point of view which has been developed and made right here in Australia.
It is a top example of smart Aussie design", Brown said.
