BUILT TO GO
WHERE THE
WORK IS.
Purpose-built mobile industrial cleaning systems, engineered and assembled in the UK around your operation. Every Alkota trailer is a complete system — not a pressure washer bolted to a trailer.
THE MACHINE
IS ONLY
THE START.
A mobile cleaning operation depends on far more than a pressure washer. The entire system — water supply, fuel, power, operator reach, wastewater management, payload, weather, security — must be engineered together or it will fail in service.
This is why every Alkota trailer is designed around the operation first, then built around the components. We ask what your system needs to do — not which trailer you want.
Water Supply
Onboard tank vs mains-fed. Storage capacity and endurance.
Power
Diesel engine, onboard generator, shore power, or battery systems.
Runtime
Hours of operation before refuelling, refilling, or recovery emptying.
Operators
Single-gun or dual-operator split manifold for maximum productivity.
Recovery
Vacuum capture, filtration, and closed-loop reuse for environmental compliance.
Payload
UK Maximum Authorised Mass, axle loading, and tow vehicle compatibility.
Security
Enclosed bodywork, locking vaults, and equipment protection.
Fabrication
Bespoke chassis engineering, livery, and company branding.
That is the question behind every Alkota trailer build. Not which trailer — but which system.
OPEN DECK
OR ENCLOSED
MOBILE PLANT ROOM.
Maximum Access.
Rapid Deployment.
Open deck systems offer unrestricted access to every component from all sides. Ideal for multi-operator setups, frequently reconfigured equipment, and operations where hose runs, engine access, and visual inspection are important.
Typical applications: Contract cleaning, heavy plant depots, agricultural mobile washdown, civil engineering, hire fleets.

REAL ENGINEERING.
Dual-Operator Heavy Fleet Washdown Rig
Designed to clean 40 HGV units per day. Twin-gun output means two operators cover twice the ground from a single hot water skid.
Closed-Loop Environmental Mobile Plant Room
Zero-runoff capability meeting Environment Agency requirements. Washes, recovers, filters, and recycles water in a single self-contained mobile operation.
Compact Urban Steam & Graffiti Rig
Ultra-compact single-axle steam rig towable behind a standard Transit. Instant 155°C wet steam eliminates chewing gum, graffiti, and bituminous contamination without damaging historic stone.
EVERY ELEMENT.
ENGINEERED TOGETHER.
An Alkota trailer is not assembled — it is engineered. Each subsystem is specified, positioned, plumbed, and wired in relation to every other. Select any component below to understand its role in the complete system.
BUILD THE
SYSTEM YOUR
OPERATION NEEDS.
The Alkota configurator works like configuring a premium vehicle — except the result is a production-ready specification for a real industrial cleaning system, sent directly to our engineering team.
FROM WATER IN
TO WATER BACK
UNDER CONTROL.
For operations requiring environmental compliance, Alkota trailer systems can integrate the complete mobile water treatment circuit — capturing, filtering, and recycling wastewater on-site without connection to any drain.
Site mains or 2,000L onboard reservoir
Hot water, cold water, or steam at pressure
Contained wash zone with portable berms
VACGD vacuum capture from 100m distance
VFS purification → recycled to tank
Closed-Loop Recovery
A fully closed-loop Alkota enclosed rig captures 100% of wash water, purifies it through 5 stages down to <5mg/L hydrocarbon concentration, and returns it directly to the onboard pressure washer supply. No drain. No trade effluent consent. No water waste.
Environmental Compliance
Washing in sensitive areas — harbours, town centres, fuel depots, water authority sites — requires containing and treating wastewater. The Alkota VFS-equipped trailer is the only mobile solution that can operate legally in these environments without additional site infrastructure.

WATER IS
VERY HEAVY.
This is why mobile cleaning systems must be engineered rather than assembled casually. 1 litre of water weighs 1 kilogram. A 2,000L tank is 2,000kg of water — before the machine, trailer, fuel, generator, hose reels, and tools are counted.

1 litre ≈ 1 kilogram

With full equipment, this fills the entire MAM

Quick Tow Vehicle Check
Enter your vehicle's maximum braked towing capacity (from the V5C logbook or VIN plate) to see which Alkota trailer chassis is within your towing envelope.
Note: All trailer configurations must be independently verified by an engineer prior to order. This tool is indicative only.
FROM BRIEF
TO COMMISSIONED RIG.
Discover
Tell us about the work — what surfaces, what contaminants, how many operators, and where the rig will travel.
Configure
Build the complete system yourself using our engineering configurator, selecting every component that fits your operation.
Engineer
Alkota engineers validate weight distribution, hydraulic compatibility, trailer approval, and tow vehicle suitability.
Approve
You receive a final engineering drawing, specification sheet, and quotation for sign-off before a single component is ordered.
Build
Your rig is handcrafted in the UK by our specialist trailer fabrication team, integrating American Alkota machinery with bespoke British engineering.
Commission
Full operational handover, staff training, documentation, and post-installation technical support from the Alkota UK team.
SOUTH DAKOTA
POWER.
ENGINEERED FOR
BRITISH OPERATIONS.
Alkota Manufacturing has built industrial cleaning equipment in South Dakota, USA, since 1964. Six decades of continuous-duty engineering. The machines are proven.
Alkota UK takes those American machines and builds them into complete British mobile cleaning systems — engineered to UK road law, UK payload limits, WRAS water regulations, and UK Environment Agency requirements.
UK Type Approval & IVA Compliance
Every Alkota trailer is individually verified or type-approved to UK road traffic law requirements — not US DOT specifications.
WRAS Category 5 Water Regulation
All onboard mains water connections incorporate WRAS-approved CAT 5 air gap break tanks preventing backflow contamination.
UK Environment Agency Alignment
Recovery system specifications are reviewed against current EA Trade Effluent and Discharge guidelines, not generic manufacturer claims.
7-Year Coil Warranty
Alkota's Schedule 80 hydro-insulated heating coils carry a 7-year warranty — the longest in the industry.
