THE JOB DEFINES THE MACHINE.
Every cleaning operation has different constraints. Water, power, mobility, duty cycle, contamination and workflow all change what the right system looks like.
Don’t buy a trailer.
Engineer a workflow.
A trailer is simply a platform on wheels. The true engineering discipline is creating a complete, road-legal mobile wash platform that enables an operator to arrive on site, deploy 60 metres of hose in 90 seconds, strip difficult contamination with continuous 90°C thermal power, capture wastewater, and pack away safely without operational friction.
Bolting an off-the-shelf pressure washer and an unbaffled water container onto a generic builder's trailer creates dangerous weight distribution, axle overloads, and maintenance headaches. Alkota UK designs and fabricates turnkey mobile systems where every component is calculated around the operator's daily contract reality.
A high-pressure pump and burner coil generating hydraulic and thermal energy.
Type-approved chassis, baffled water storage, prime mover, live hose reels, chemical dosing, closed-loop recovery, work lighting, and technician service access.

Requirement & Operational Audit
Defining the operational envelope
We evaluate your daily target surfaces, contract commitments, towing vehicle capacities, and operational shifts to establish baseline requirements.
The Pressure Washer is Only One Component

03 / Alkota Industrial Pressure Washer Skid
High-Output Hydraulic & Thermal PowerhouseContractors and heavy industry require continuous 100% duty cycle washing without thermal degradation.
Industrial diesel or petrol-driven triplex ceramic plunger pump delivering 150–350 BAR and 15–35+ L/min with vibration isolation mounts.
1,450 RPM slow-running pumps run cooler, pull water smoother, and last up to 5x longer than direct-drive 3,400 RPM consumer pumps.
Water is Part of the Payload
Calculate your trailer’s gross operating weight (wet) and determine the recommended chassis axle rating.
Tandem-Axle Heavy-Duty Chassis (2,700kg – 3,500kg Gross Weight)
Requires towing vehicle with 2.8T–3.5T towing capacity and category B+E driving entitlement.
*Illustrative engineering weight estimation. Actual payload verified via calibrated axle scales on completion.
We don’t start with PSI.
Adding heat changes the whole system.
Consumer pressure washers market headline PSI numbers. In commercial mobile engineering, we start with the contaminant and work backwards:
Integrating an industrial hot-water burner introduces substantial engineering factors: high-efficiency diesel combustion, flue gas ventilation, vibration-isolated fuel lines, electrical flame sensing, and ASTM A53 Schedule 80 heavy-wall seamless steel coils capable of handling continuous 90°C thermal output.
- Industrial Diesel / Petrol Engines: Kubota, Honda, and Vanguard engines with electric start and low-oil cutouts.
- Auxiliary Power Generators: 240V/110V power generation for onboard vacuum recovery and jobsite floodlights.
- Battery Management: High-output engine alternators with smart trickle charging and master isolators.
The hose is the operator’s working range.
The trailer is a workstation.
In contractor operations, job profitability is dictated by setup and pack-down speed. Dragging 50 metres of tangled hose across a busy high street or distribution yard wastes time and creates acute trip hazards.
Alkota builds feature direct-plumbed stainless steel live hose reels mounted at ergonomic waist height with 4-way roller guides. Operators simply pull out the exact hose length needed and begin washing immediately. When finished, heavy-duty gear-reduction hand cranks or electric rewinds retrieve the hose in under 60 seconds.
- Kerbside Control Access: Operating controls facing the footpath rather than live highway traffic.
- Slide-Out Service Trays: Pump and engine slide outward on heavy-duty lockable runners for effortless maintenance.
- Lockable Tool Vaults: Secure, integrated storage for lances, surface cleaners, nozzles, and chemical canisters.

Antarctica: The Half-Mile Machine
HALF A MILE THROUGH THE ICE.
In January 2013, an expedition team achieved the first clean hot-water access through 800 metres of West Antarctic ice into Subglacial Lake Whillans. Operating at the core of the thermal heating system were six Alkota pressure-washer units.
