The WINDOWWASHER by ITR is a quiet and efficient diesel-fired continuous output water heater. The diesel burner provides 35,000 TRUE OUTPUT™ BTU for directly heating water for clean applications, and fires independent of the vehicle engine.

The WINDOWWASHER provides continuous 38°C water at 3.5 liters/min or 28°C at 6.0 liters/min, and has an internal mixing valve to set a preferred hot water temperature.

The WINDOWWASHER features a stainless steel 300 PSI welded tank, stainless steel outer case, and a high temperature stainless steel burner. The stainless steel construction ensures that the water supplied to the WINDOWWASHER is delivered clean. THE WINDOWWASHER also features on-board self-diagnostics.

Like all ITR products, THE WINDOWASHER features ITR’s patented low-pressure burner platform that offers uniquely safe, quiet, “no-smoke, no-smell,” technology, while also improving efficiency and lowering system maintenance cycles.
