Recovery & Filtration System

Feature: The integrated water reclaim and filter system recovers wash water utilizing a 120-volt vacuum turbine producing 105 CFM. A 12- volt transfer pump moves the water through a multi-stage filtration system that consists of a 50-mesh/100-micron pre-filter sock, a 20-micron pleated polyester cartridge filter, 5-micron carbon filter, and an oil absorbent media sock. Treated water can be recycled through the water storage tanks for re-use or discharged to an approved drain. Consult your local EPA for discharge limitations.

Benefit: LANDA’s ECOS Mobile Wash and Reclaim System recovers, cleans and recycles dirty water from pressure washing for safe disposal or reuse to meet most municipal and environmental regulations.

Trans-Heat Technology.jpg

Trans-Heat Technology

Feature:  Patented Trans-Heat Technology by LANDA. Inlet water, typically around 60°F starting in the tanks, is directed to the feed pump and received by the Trans-Heat Technology heat exchanger. The heated exhaust gases from the engine are captured and diverted through a heat exchanger, preheating inlet water by up to a 15°F temperature rise. From the heat exchanger, water is routed to the LANDA high-pressure pump and heating coil resulting in up to a 140°F temperature rise. Hot water is then released through the high-pressure hose reel, wand, and gun.

Benefit:  By preheating inlet water before it reaches the main heating coil, the engine and burners do not have to work as hard, resulting in less wear and tear on the unit. This efficient method of heating water translates to fewer emissions, greater fuel savings, and greater profitability.

ECOS Vacuum Hose.jpg

2 Inch Vacuum Hose

Feature:  The ECOS comes with a 50-foot, 2-inch vacuum hose and fits well within the lockable storage area along with the vacuum head, extra parts, spare filters, and other accessories.

Benefit: Vacuum hose storage ensures a neat and tidy galley, ample room to move around with room to spare! Additionally, having secured storage for spare filters ensures that the operator never runs out of supplies in the middle of a job.

Control Panel.jpg

Control Panel


All system controls are conveniently placed curbside. They mounted control panel with protective and lockable cover includes a key start, choke, burner switch, adjustable thermostat, and an hour meter.

Benefit: Electrical controls are mounted on the side for quick access, and housed in a water resistant box to protect from moisture. The adjustable thermostat allows for altering the water temperature to match the operator’s application. The hour meter displays the engine running hours so that regular preventative maintenance can be performed ensuring peak performance.

Control Valves

Feature: Tank and bypass water control valves are conveniently located in the lockable control panel cabinet on the curbside of the unit. Bypass water can be directed to either the inner or outer set of tanks. Operators can easily transport 400 gallons of water in a tandem cabinet, or they can isolate fresh water from treated water by setting the supply tank valves to separate into two 200-gallon tanks. For service and reliability, all fittings are brass or treated steel, and they feature JIC-style fittings at connection points.

Benefit:  Easy-to-use labeling takes the guesswork out of water flow providing peace of mind for the owner and operator. Quality JIC-style fittings, including zinc-coated steel, are easy to connect and disconnect, provide rust protection, and are rated for withstanding high pressures.

ECOS Unit Adjustable Thermostat.jpg

Adjustable Thermostat

Feature: The thermostat regulates the water temperature of the unit. The ECOS includes an adjustable

thermostat conveniently located in the side lockable steel control panel.

Benefit:  The easily accessible thermostat, adjustable up to 200°F, allows the operator to match the temperature to the job and prevent overheating.

ECOS Unit Tuff Skin Hose.jpg

Tuff Skin Hose

Feature: This 50-foot long, half-inch double steel braid LANDA Tuff- Skin hose is the toughest high-pressure hose in the industry. When tested at 6945/DIN20024, the Tuff-Skin has proven to be seven times more abrasion resistant than standard pressure washer hoses, yet it is 20 percent more flexible. The Tuff-Skin Hose has a unique braid design and has been engineered for a greater continuous temperature range: from 40° to 275°F/310°F intermittently. It can handle pressures of up to 5,800 PSI, has a maximum strength Class A ORS (Oil Resistance Standard) cover, and features a bite-the-wire coupler that grips the hose better than any other design.


Benefit:  Due to its abrasion resistance and flexibility, the Tuff-Skin Hose holds up better than any other hose in outdoor pressure washer environments where hose typically gets whipped, twisted and yanked around. The maximum strength Class A cover rating means it will hold up to oils, grease and fats much better than the more commonly used Class B. The 50-foot hose gives the operator some slack to clean freely with out feeling encumbered by the pressure washer.

High Pressure Nozxles ECOS.jpg

High Pressure Nozzles

Feature: Nozzles are what create the pressure or cleaning power of the pressure washer. Four color-coded, hardened stainless steel, high-pressure nozzles are mounted in the rear adjacent to the high-pressure hose reels. Nozzles attach to the end of the wand with a quick coupler. The colors designate the spray patterns created by each nozzle: Red=0°, Yellow=15°, Green=25°, and White=40°.


Benefit:  The hardened stainless steel ensures the nozzles will hold up well without rusting or disintegrating during months of regular operation. The quick-couple makes switching nozzles quick and easy without the need of additional tools. The distinct colors allow the operator to quickly identify the flow patterns available. Having a variety of flow patterns, from the narrow 0° stream to the broad 40° spray, gives the operator plenty of options to meet whatever cleaning task is at hand.

Variable Pressure Wand ECOS Unit.jpg

Variable Pressure Wand

Feature: The variable pressure wand is 41 inches long and consists of two adjoined, insulated, zinc-coated metal tubes. An easy-grip handle on the side of the wand twists to increase or decrease the pressure. When the wand is set to high pressure, water is forced through the main pipe and out through the quick-coupled nozzle at the end of the wand. When it is set to low pressure, water is diverted to the second pipe to reduce the flow volume in the main pipe, thus reducing the pressure of the main water stream. A durable, plastic hood or nozzle covering is mounted at the end of the wand.


Benefit:  Having an easy way to manage the spray volume at the point of the wand makes the job easier for the operator. It also allows for better control when dispersing detergent when a downstream detergent injector is attached. The wand handle is turned to create a low-pressure flow, which immediately begins drawing in detergent into the spray. With the twist of the handle, clean water comes out again as a high-pressure spray. The wand length prevents an operator from spraying him/herself. The easy-grip handle is mounted at the right angle for hours of fatigue-free spraying. The plastic hood at the tip helps protect the nozzle and objects being cleaned.

Secure Storage

Feature:  The ECOS contains a steel storage compartment on the driver side, which can hold two 5 gallon buckets nestled on top of the two 17-gallon fuel tanks. Another storage compartment on the passenger side can hold small items such as a small toolbox, electrical cords, or cleaning supplies


Benefit:  This compartment helps to keep fuel and storage buckets secure and tucked out of the way.

The Open Galley

Feature:  An 84-inch long by 30-inch open galley creates accessibility to tanks, storage spaces, and pressure washer. 


Benefit: The open galley allows an operator to haul and store additional tools and supplies, enabling the ECOS to be a more sufficient trailer. Moreover, the rear gate with detachable lock pin provides some security for tools and equipment stored in the galley.
