The AlphaTherm Windshield Washer Fluid Heater dramatically improves the performance of your vehicle’s windshield washer system by heating your washer fluid to 140 degree Fahrenheit. The hot fluid is dispensed via the vehicle factory washer switch while utilizing the fluid in your factory washer reservoir. In the winter months, the heated fluid is used to melt frost, ice, and snow off of the windshield and wiper arms. The hot fluid can prolong the life of your wiper blades and improve the spray pattern of the fluid on your windshield. The heated wash feature can prevent standing outside scraping the windshield in cold or unsafe areas. During warmer months the unit helps to eliminate summer glare by removing road oil, haze and streaks and quickly dissolve and remove mud, dirt, bird dropping and sap. The heated fluid will never crack the windshield. The unit is simply connected to the vehicle battery and washer hoses and is designed to keep several ounces of washer fluid between 130°F and 140°F at all times while the engine is running. Once installed, within 40 seconds after the vehicle is started a three to four second spray of heated washer fluid is available. After the first 4 second spray an additional 4 second spray is available every 15 seconds. The AlphaTherm design is currently the world leader in quality, development and sales of windshield washer fluid heating systems. The AlphaTherm heated wash is made in the USA and backed by a one year Warranty.
