As part of the continuous optimization of its infrastructure maintenance operations, the municipality of Saint-Adolphe-d'Howard acquired custom-built mobile equipment. We designed and assembled an industrial mobile pressure washer platform, tailored to handle the terrain requirements of the Laurentians.
Mounted on a skid to fit into a light service vehicle or pick-up truck, this unit incorporates top-tier industrial components to ensure autonomy, durability, and operational safety. This article details the full technical architecture and the value added by this Multi PSI realization.

The cornerstone of this project is the heavy-duty steel Hydro Tek T270T skid platform. Specifically dimensioned for municipal service truck beds, it provides secure anchoring for all wash modules. The platform features a main water tank with a 270-gallon capacity, made of impact-resistant high-density polyethylene.
To guarantee smooth operation without risk of overflow or pump cavitation, the setup includes advanced regulation equipment:
At the core of the setup lies the Hydro Tek SC35006HG hot water pressure washer, an industry benchmark for heavy-duty autonomous cleaning. This unit pairs a highly reliable Honda GX630 twin-cylinder gas engine with a commercial-grade industrial General ceramic plunger pump.
Technical specifications of the main unit include:
To meet the demands of Laurentian winters, this customized platform incorporates a dedicated configuration for de-icing and maintaining stormwater drainage networks. Unblocking frozen culverts and pipes requires precise control over pressure and flow.
The culvert thawing package includes:
Workplace ergonomics relies on organized hose management. A welded steel reel rack securely anchors the hose reels onto the T270T skid platform. The unit features 3 separate manual reels to prevent tangling and speed up deployment:
The onboard hose package includes:
Cold weather operations demand the ability to purge the wash system after night shifts or exposure to freezing temperatures. Multi PSI integrated a complete winterization setup featuring a dedicated 10-gallon antifreeze tank.
Using a 3-way valve system, the operator can flush antifreeze solution through the pump, burner coil, hoses, and reels in under three minutes. This simple routine protects internal components against frost, preventing costly damage to pump manifolds and heating coils.

Industrial pressure washing platforms mounted on pick-up trucks have become essential equipment for municipalities and contractors. They provide a mobile, versatile, and highly efficient solution for heavy-duty cleaning tasks, eliminating the need to tow trailing units or separate water tanks.
Their compact footprint saves valuable setup time, a critical factor for crews maintaining clean and safe municipal infrastructure. Thanks to their mobility, these skid platforms can be deployed rapidly to any work site, boosting productivity across various sectors, including public works, construction, and fleet maintenance.
At Multi PSI, our mission is to translate complex operational needs into reliable and ergonomic machinery. Designing this custom platform highlights our technical proficiency in high-pressure fluid engineering.
From engine selection to filter and valve integration, every engineering choice aims to maximize long-term return on investment. We work closely with municipal and commercial fleet managers to supply turnkey equipment built to perform.
The successful deployment in Saint-Adolphe-d'Howard illustrates the value of partnering with a specialized local manufacturer. Beyond custom builds, Multi PSI offers full maintenance support, replacement parts, and technical assistance.

The T270T skid platform is equipped with a 270-gallon polyethylene tank, providing approximately 45 minutes of continuous wash time at a flow rate of 6 gpm.
The installation features a polypropylene electric float switch and a low water cut-off sensor that automatically stop the engine/pump drive if tank water levels drop too low.
This foot pedal valve allows the operator to control high-pressure water flow hands-free while jetting pipes or culverts, keeping both hands available to handle the hose line.
The stainless steel construction of the Hydro Tek reels prevents corrosion from hot water and antifreeze, while the heavy-duty Hannay Reels frame provides the structural strength required for larger diameter hoses rated up to 4000 psi.
The 10-gallon tank holds antifreeze fluid. Using a 3-way valve setup, the solution is drawn directly through the pump and burner heating coil to flush out water prior to cold storage.
Water passes through a 5" blue cap inlet filter before going through a 5" 25-micron Polyspun filter cartridge, trapping fine particulates to safeguard the ceramic pump plungers.
These specialized nozzles use high-pressure water jets directed backward to propel the hose forward into blocked pipes while spinning to clear ice build-ups and debris.
Yes, the 115-volt generator built into the Hydro Tek unit powers the diesel burner system and includes accessible outlets to run jobsite lights or electrical tools.
The T270T platform is designed to fit inside a full-size truck bed (3/4-ton or 1-ton series) capable of carrying the equipment plus 270 gallons of water (approx. 2,700 lbs of water weight).
A bypass system redirects circulating water back to the 270-gallon tank, allowing the water to cool off rather than overheating inside the closed pump manifold.
