Electric water pump gains intelligent
control
The release of the new generation electronic management for the innovative EWP gives drivers an instant choice between power or economy at the press of a button.
The ability to easily dial the maximum power or optimum economy with an innovative engine management system is proving a winner for Australian cooling system specialist Davies Craig The Melbourne-based innovator first won international acclaim with its EWP electric water pump and last year followed with the super smart digital controller which is now scooping design awards around the world
The release of the new generation electronic management for the innovative EWP gives drivers an instant choice between power or economy at the press of a button.
This results in the engine being able to alter its operating temperature anything between quickest warm-up to maximum cooling or peak temperature.
When fitted in conjunction with Davies Craig Thermatic fan(s), the digital controller works by simply fitting the sensor into the thermostat housing, connecting the EWP, and programming the engine's cooling system to the preference of the driver and conditions.
This is achievable because the digital 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 minimise 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 modern cars are fitted with an engine cooling thermostat preset to a single temperature.
That is a compromise between power and economy but it delivers neither with full efficiency.
Whereas the digital 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 worldwide sales", 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 as 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 - as simple as that".
"We've put in considerable investment on the production methods that make this digital 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".
"And while we're obviously proud of the many design awards which come back to us from various countries, the best recognition of all is the way our export business is growing strongly".
"This is a top example of smart Aussie design now winning globally", Brown says.
