INDUSTRIAL POWER.
BUILT TO OUTLAST.
Six decades of heavy American industrial engineering. Heavy cold-rolled steel chassis, slow-turning ceramic triplex plunger pumps, and continuous-wound Schedule 80 seamless heating coils. Built for continuous duty where equipment failure halts production.
Handcrafted in Alcester, South Dakota since 1964. Distributed, specified, and supported across the United Kingdom.
Heavy industrial cleaning systems engineered for continuous duty where equipment downtime halts production.
Every Alkota machine is built around structural cold-rolled steel, slow-turning industrial ceramic plunger pumps, and ASTM A53 Schedule 80 seamless steel heating coils. When transport depots, manufacturing facilities, agricultural operations, and food processing lines demand absolute reliability, they specify Alkota.
420X4 HOT WATER PRESSURE WASHER
The workhorse of UK fleet depots and heavy industrial plant. Schedule 80 continuous-wound spiral heating coil with dual-pass burner delivers instant thermal breakdown of heavy road film, bitumen, grease, and hydraulic oil.
ENGINEERED BY CATEGORY.
High-Temperature Grease & Oil Breakdown
Schedule 80 continuous-wound spiral heating coils delivering water temperatures up to 95°C at pressures to 345 bar. The industry benchmark for fleet wash bays, agricultural plant, and industrial manufacturing.
BUILT FOR YOUR INDUSTRY.
Continuous-duty cleaning for combines, grain stores, livestock housing, and slurry systems.
MESS QUEST.
No studio staging. We put standard Alkota hot water pressure washers to work on the toughest industrial contamination in the field.
ENGINEERED WITHOUT WEAK POINTS.
Industrial pressure washers fail at thermal welds and high-speed bearings. Alkota eliminates captive weak points with heavy-gauge metallurgy and proven open-architecture industrial components.
Schedule 80 Continuous-Wound Steel Coil
ASTM A53 Cold-Rolled Seamless Pipe · 7-Year Guarantee
Wound on precision CNC mandrels with zero internal welds. Schedule 80 pipe features 35% heavier wall thickness than commercial Schedule 40 coils, resisting thermal shock and high operating pressure for decades.
Slow-Turning Ceramic Triplex Plunger Pump
Forged Brass Manifolds · Solid Ceramic Pistons
Operating at low RPM dramatically reduces internal friction, cavitation, and thermal degradation of V-packings. Built for continuous multi-shift industrial operation.
Dual-Pass Aerodynamic Combustion Chamber
Precision Flue Gas Labyrinth · 82–86% Thermal Efficiency
Engineered dual-draft airflow captures maximum latent heat from diesel, kerosene, or natural gas burners directly into the Schedule 80 coil stack.
Technical whitepaper on Barlow’s formula, hoop stress calculations, and coil wall metallurgy available in The Lobby.

Founded in Alcester, South Dakota in 1964, Alkota has continuously refined industrial high-pressure heating systems for the world’s most demanding environments.
In 2013, custom-engineered Alkota hot-water heating systems were selected to power the clean-water hot drill reaching Subglacial Lake Whillans — 800 metres beneath the Antarctic Ice Sheet. Operating in continuous sub-zero conditions, Alkota delivered uninterrupted thermal performance.
ENGINEERED AROUND YOUR APPLICATION.
From single-axle highway wash rigs to multi-lance skid-mounted plant, Alkota designs turnkey bespoke mobile cleaning systems tailored to your site specifications, water volume, and transport platform.
CLOSED-LOOP WATER RECOVERY.
Hydro-cyclonic separation and filtration systems engineered for UK wash bay environmental compliance. Recycle wash water, reduce mains water consumption, and meet Environment Agency trade effluent requirements.
THE LOBBY.
UK Wash Bay Environmental Compliance: Drainage, Oil Separators & Trade Effluent Consents
Discharging wash water into surface water drains is a criminal offence under the Environmental Permitting Regulations. Here is what UK commercial operators must install to remain fully compliant with PPG3, BS EN 858, and Water UK guidelines.
Vapour Steam vs High-Pressure Hot Water: Thermal Breakdown Mechanics for Food Processing & Degreasing
When should an industrial facility deploy 140°C dry vapour steam versus 250 bar high-volume hot water? We compare the thermodynamics, sanitisation efficacy, and mechanical surface impact of both technologies.
