The Alpha Therm Heated Wash is presently the only proven, effective windshield washer fluid heating system that offers consumers both safety and convenience at an affordable price.

The Alpha Therm Heated Wash patented, and proprietary technology enables its heating system to heat windshield washer fluid using a minimal amount of energy produced by the vehicle’s electrical system to remove frost, ice, snow, bugs, glare and other debris.

The Heated Wash has been proven to be safe and effective in tests on all types of windshield glass and in many environments.

Get ready to see the difference when you install the AlphaTherm Windshield Washer Heater. By heating your wiper fluid to over 125 degrees F, the AlphaTherm Washer Fluid Heater sprays your windshield with a super-heated mist of fluid for powerful cleansing.

Once installed, the AlphaTherm unit works in conjunction with your factory washer spray. Just activate the spray control and the heated fluid mists your windshield to clear ice and frost in winter - bugs and road grime in summer.

The AlphaTherm Windshield Washer Heater bolts easily in your engine compartment and utilizes the fluid in your factory washer reservoir. Powered by your vehicle’s electrical system, the washer fluid heater uses very little energy, yet is always ready to mist your windscreen with heated fluid.

The heated fluid also helps preserve the life and bolsters the effectiveness of your wiper blades. Plus, it unblocks frozen or clogged spray nozzles and keeps them clear for maximum coverage. Best yet, AlphaTherm backs your Windshield Washer Heater with a frost-free 1-year warranty.

Heated Wash AT-38OD operates in “On-Demand” mode.

The unit starts to operate when the ignition is on (engine running) and battery voltage level is higher than 13.0 volts. Once the unit is activated, the washer fluid inside its heating chamber will be heated and kept within pre-determined temperature limits (125 – 135°F), so there is always hot fluid inside the unit’s heating chamber which can be used by a driver for cleaning the windshield.

Each time the driver activates the factory installed washer system, heated washer fluid is applied to the windshield for approximately the first 3 seconds of spray. Three seconds of the spray delivers approx. 50-60 cc of fluid that is considered sufficient amount of fluid for one spray. The next portion of heated washer fluid is available in 10-20 second (depending on ambient conditions).

The Heated Wash unit uses full power of 50 Amps for 30 seconds to heat the washer fluid up to pre-determined temperature limits (125 – 135°F), and minimal power to keep it within these limits. The unit’s power consumption is less than 2 Amps per hour.

Once the unit starts to operate (engine is running), it will heat the washer fluid in approximately 30 seconds; driver operates the washer system manually to spray the heated washer fluid onto the windshield. Recommended duration of spray is 3 seconds. Driver can spray as many times as he wants. Best results are achieved when time intervals between sprays are approx. 20 seconds
