Technical Features and Structure of the De-Icing Trailer

The foundation of any mobile unit built for the Far North lies in the strength of its chassis, its insulation, and the distribution of its load. A washing trailer exposed to unpaved roads and constant vibration must offer optimal stability.

Dimensions and Load Capacity

The structure has optimal dimensions of 8 feet wide, 14 feet long, and 6.8 feet of interior height. This space allows all the machinery to be integrated while still leaving a circulation area for the operator.

To support the weight of the 525-gallon water tank and the mechanical units, the unit rests on two axles, each rated at 5,200 lb. This configuration guarantees a significant safety margin when traveling on rough roads.

Materials and Exterior Protection 

The exterior shell uses lightweight, durable materials to resist salt corrosion and moisture:

• Tongue and lower door panels in ultra-resistant embossed aluminum.
• Reinforced wheel caps to protect the bearings from rock projections.
• A fully sealed structure protecting the interior equipment from powder snow infiltration.

Thermal Insulation, Urethane, and Freeze Protection 

Maintaining good heat inside the trailer is the top priority when the outside temperature drops drastically.

Insulating Envelope and Urethane

Thermal protection is provided 360 degrees around thanks to a complete combination of insulating materials:

• Under-floor insulation: A layer of high-density spray urethane applied under the exterior chassis blocks the heat transfer caused by snow and wind under the trailer.
• Ceiling and walls: An insulation system combining expanded polystyrene (Styrofoam) and a reflective thermofoil membrane to retain interior heat.
• Interior finish: Panels covered with washable white plastic, ensuring watertightness and resistance to splashes.

Secure Flooring and Integrated Heating

The floor is covered with a specialized industrial Lyne-X coating with a non-slip border. This surface prevents slips caused by water or oil while sealing the floor against moisture.

A standalone heating system is built directly into the interior lining. It provides constant heat to keep the mechanical components warm during downtime or while in transit.

Hydro Tek High-Pressure Washer

At the heart of the de-icing trailer is the pump-motor unit and a burner that serves as a high-pressure water heater. The SC30009KAK high-pressure washer meets this need precisely.

Pump and Engine Performance 

The system relies on a Hydro Tek unit built from stainless steel, resistant to corrosion. The Kohler gasoline engine provides the power needed to achieve:

• A pressure of 3,000 PSI to break up firm ice and embedded dirt.
• A water flow of 8.5 gallons per minute (GPM), essential for quickly rinsing large surfaces.

Burner Capacity and Integrated Generator

To ensure total field autonomy, the high-pressure washer includes an auxiliary 3,000-watt generator supplying 115 volts.

This built-in generator is driven directly by the main engine. It eliminates the need to carry a bulky external generator and can power:

• Work lighting for nighttime interventions.
• The trailer's electrical systems (such as the motorized reel).
• Small power tools.

The diesel burner, for its part, delivers 550,000 BTU of thermal power to bring water to very high temperatures within seconds.

Water Tank, Detergents, and Dual Filtration 

Water supply is a major challenge on remote job sites in Northern Québec. That's why the equipment is fitted with a large water tank for extended autonomy.

Main Tank and Detergent Distribution

The trailer has a 525-gallon horizontal tank anchored by steel hoops. For intensive washing operations, a secondary vertical tank with a conical bottom allows soaps and detergents to be stored. Its conical shape ensures complete, continuous drainage without residue buildup at the bottom.

Mechanical Protection via the Dual Filtration System 

Water drawn from wells, lakes, or job-site reservoirs often contains sediment or fine particles. To protect the internal components of the Hydro Tek pump and the burner coil, the trailer is equipped with a dual filtration system:

• First filtration stage: A primary screen filter holds back large debris, sand, and gravel at the network's inlet.
• Second filtration stage: A fine cartridge filter blocks heavy microparticles and suspended limescale.

Reels, Accessories, and Ergonomic Storage 

Every tool needs a fixed place to avoid clutter and ensure safety during transport.

Reels and Mounts

• A Hannay Reels spring-loaded reel that can hold up to 100 feet of high-pressure hose for quick interventions.
• A Hannay Reels electric reel, running on 12 volts, fitted with a 300-foot thermoplastic hose known for staying flexible below 0°C.
• Vertical stainless-steel wand holders mounted on the walls to keep guns and lances within reach.

Safety Devices, Ventilation, and Exhaust 

Using a 550,000 BTU burner in an enclosed space requires rigorous safety installations.

Gas Exhaust and Roof Ventilation 

The stainless-steel exhaust chimney is protected by a black metal mesh cage preventing accidental contact with the hot surface. Gases are vented through a sealed roof hatch topped with a debris-guard grille.

Antifreeze Management 

The trailer includes an antifreeze management unit connected to the pumping lines, allowing an antifreeze solution to be quickly injected into the internal circuits to purge the water at the end of the work. 

Versatile Applications 

Although designed to withstand the Far North, this washing trailer offers ideal versatility for many professional applications throughout the year. 

Industrial and Commercial Uses 

Its full autonomy allows for rapid intervention at various sites:

• De-icing of construction equipment, heavy machinery, and mining vehicles.
• Cleaning of business parking lots, private residences, and commercial facades.
• Maintenance of service areas at gas stations and shopping centers.

Special Events and Emergency Interventions 

The trailer's mobility allows for on-site washing services without requiring permanent water or electrical infrastructure. It's the go-to tool for trade shows, auto shows, and outdoor events requiring quick high-pressure cleaning.

Frequently Asked Questions (FAQ) About De-Icing Trailer

Why is urethane applied under the trailer's chassis?

Urethane under the floor creates a continuous insulating barrier. This prevents ambient cold and accumulated snow underneath the trailer from cooling the floor and the internal water network.

Why is a dual filtration system essential in the Far North?

In remote areas, fill water often comes from unfiltered sources. The dual filtration system first holds back large debris, then fine particles, preventing impurities from blocking nozzles or damaging the pump's pistons.

What is the conical tank next to the Hydro Tek washer used for?

This tank is used to store cleaning detergents and soaps. Its conical shape allows for complete drainage of the product from the bottom without leaving any residue.

How does the de-icing trailer prevent water from freezing during transport?

The trailer combines overall insulation (urethane, Styrofoam, thermofoil) with interior heating. An antifreeze purge unit allows an antifreeze solution to be quickly injected into the pump and hoses after use.

What is the maximum water temperature produced by the Hydro Tek burner?

The 550,000 BTU burner can raise water to steam temperatures of 90°C to 120°C depending on the flow rate used, allowing compacted ice to melt very quickly.

What type of vehicle is required to tow this washing trailer?

With two 5,200 lb axles and a full 525-gallon tank, the total weight can exceed 6,000 lb. A Heavy Duty pickup truck (2500/F-250 or higher) equipped with an electric braking system is recommended.

Does the 300-foot hose stay flexible below 0°C?

Yes, the hose is made of high-performance thermoplastic specifically designed to stay flexible and resist cracking even in below-freezing temperatures.

How does the burner's gas exhaust system work?

The burner is connected to a stainless-steel exhaust chimney surrounded by a burn-protection grille, leading out to a sealed roof hatch outside.

Why is the Lyne-X flooring important in a washing trailer?

The Lyne-X coating provides watertight protection against water and chemicals while creating a non-slip surface essential for operator safety in wet environments.
