845S
845S — Gas & Diesel Cold Water Pressure Washers
BUILT FOR SERIOUS OPERATORS.
Alkota 845S is an industrial-grade cold water cleaning system engineered in South Dakota by Alkota and built for the demanding conditions of UK commercial and industrial operators. Delivering 276 bar (4000 PSI) at 30.3 L/min (8 GPM), it features Alkota's signature heavy-gauge welded chassis and precision-engineered oil bath crankcase|triplex ceramic plunger.
Built for intensive continuous duty, the Alkota 845S combines high-efficiency heat exchange with industrial-grade mechanical components. Alkota's proprietary coil technology features a hydro-insulated cold-water wrap that protects operators, pre-heats incoming water, and eliminates thermal shock — backed by a 7-year warranty.
Oil Bath Crankcase
Oil-bath crankcase and ceramic plungers running at lower RPM for cooler, vibration-damped longevity.
Schedule 80 Hydro-Insulated Cold Water Wrap Coil Coil
Hydro-insulated cold water wrap pre-heats water, protects operators, and eliminates thermal coil stress.
7-Year Coil Warranty
The benchmark in industrial heating reliability. Alkota Schedule 80 coils are guaranteed for 7 years.
Welded Steel Chassis
Heavy-gauge welded structural steel frame with powder coat finish built to survive demanding site environments.
