Instant fluid heater module from IRC WAFT

TT electronics IRC WAFT, in cooperation with AB Automotive Electronics, a division of TT electronics that specializes in automotive control designs, has developed a windshield washer fluid heater module that utilizes patent-pending technologies and construction designs. This solution provides vehicle design engineers with an instant heating technology for automotive and transportation windshield washer applications.

Tubular fluid heater
The module combines IRC's anodized aluminum substrate technology with a thick film resistive element to produce a tubular instant fluid heater. Unlike conventional reservoir-style washer fluid heating systems, the Anotherm Windscreen Module does not use any power until heated fluid is required, resulting in an energy-efficiency of more than 95 percent.

According to Wilson Hayworth, product manager for IRC WAFT, the windshield washer fluid heater provides heated fluid in about 5s. "Due to the power limitations of most vehicles at 14.5Vdc, a preheat period of typically 5s is required prior to the first fluid dispense. Our windscreen fluid heater module is able to provide this heat due to the low thermal mass of the system," said Hayworth. "The Anotherm module heats quickly and evenly, thus it does not boil away additives such as methanol or ethanol, which are often added to improve the cleaning effectiveness and prevent the windshield washer fluid from freezing." The heating system will be available for model year 2009 platform releases, Hayworth added.

Underhood environs
The Anotherm Windscreen Module includes integrated controls and is packaged for underhood environments. Typical operation is 50A (max) at 14.5Vdc. The heated fluid effectively removes ice, tar, oil film and bugs from windshields.

Pricing and lead times vary for the custom Anotherm Windscreen Modules.
