Hot Water Pressure Washers
Alkota hot water pressure washers combine high-pressure kinetic force with up to 95°C thermal energy to melt bonded grease, engine oils, road bitumen, and biological contamination across the UK’s most demanding industrial sectors.
Why Heat Changes the Equation
Cold water under high hydrostatic pressure can blast loose soil and aggregate away, but it cannot dissolve petrochemical bonding. Hot water elevates the wash surface temperature beyond the melting point of grease (60°C–90°C), allowing thermal energy to do the heavy mechanical lifting.
Instant Petrochemical Breakdown
Rapidly melts bonded engine oil, hydraulic fluid, diesel soot, and road bitumen without requiring extreme abrasive pressure.
60% Reduction in Chemistry
Thermal energy does the heavy surfactant work, substantially reducing annual chemical spend and trade effluent treatment costs.
Halved Operator Wash Cycles
Accelerates cleaning throughput on commercial haulage fleets and plant machinery by up to 50% per bay.
Zero Moisture Pooling
High-temperature wash surfaces dry almost instantly, preventing water entrapment and post-wash flash corrosion on steel chassis.
Commercial fleet haulage depots, heavy plant hire, agricultural machinery, oilfield services, and high-volume wash bays.
Light dust or clay rinsing where fuel overhead is unnecessary (specify Cold Water instead).
Engineered Configurations & Chassis Formats
Alkota builds multiple distinct mechanical architectures within each category to match your specific power supply, fuel availability, continuous duty cycle, and mobility requirements.
Belt-Driven Electric / Oil-Fired
Low-RPM industrial motor coupled to a triplex ceramic plunger pump via heavy-duty cast iron pulleys and cogged V-belts. Runs cooler, dissipates vibration, and is engineered for continuous multi-shift operation.
Permanent wash pads, commercial fleet haulage depots, and plant hire service bays.
