4308 — All Electric Zero-Emission Hot Water Pressure Washer
BUILT FOR SERIOUS OPERATORS.
Alkota 4308 is an industrial 207 bar (3,000 PSI) all-electric hot water pressure washer engineered for UK heavy industrial processing facilities and indoor wash rooms. Delivering 13.2 L/min (3.5 GPM) with a 7.5 hp continuous-duty motor and 60 kW electric heating vessel, it eliminates heavy grease, road grime, and industrial residues with zero exhaust emissions.
Built for operators needing high-pressure hot water washing inside buildings without running expensive flue ducts or dealing with exhaust fumes. The 4308 features a Schedule 80 stainless steel immersion heating system, heavy gauge welded steel chassis, and industrial ceramic triplex pump.
Oil Bath Crankcase
Oil-bath crankcase and ceramic plungers running at lower RPM for cooler, vibration-damped longevity.
Stainless Steel Immersion Pressure Vessel Coil
Hydro-insulated cold water wrap pre-heats water, protects operators, and eliminates thermal coil stress.
5-Year Coil Warranty
The benchmark in industrial heating reliability. Alkota Schedule 80 coils are guaranteed for 5 years.
Welded Steel Chassis
Heavy-gauge welded structural steel frame with powder coat finish built to survive demanding site environments.
