Idromatic Astra EL – Electric Hot Water Pressure Washers

The Idromatic Astra EL series features fully electric hot water pressure washers with no diesel boiler – meaning zero smoke emissions and silent heating. Using instant 6-phase electric heating with AISI 316 stainless steel armoured elements, water is heated to 90°C without the need for a water softener. Ideal for indoor environments where exhaust fumes are not acceptable.
