PDHW Series
Up to 4.7 GPM, and 3,500 PSI Up to 9.8 GPM, and 3,200 PSI
Landa’s PDHW is a diesel-powered, hot water pressure washer that combines the versatility of a compact size with the ruggedness and cleaning power of a larger full-skid pressure washer. The PDHW delivers cleaning power of 3,500 PSI with a flow rate of 4.7 GPM.

The PDHW is packed with Landa quality throughout. Powered by a reliable Kubota electric-start engine, the PDHW features a top-of-the-line, oil-bath, tri-plunger, belt-drive Landa LT pump with 7-year warranty. The heating coil is made of 1⁄2-inch Schedule 80 cold-rolled pipe with a stainless steel outer top wrap. The sturdy steel frame gets all-weather protection from a polyester powder coat finish or stainless steel.
The PDHW is versatile with features and options that make it adaptable to specialized jobs. A 2,900 watt generator (on 120V burner models) provides power for the burner as well as a 120V outlet for low-wattage applications. The PDHW has forklift guides for transporting and brackets for mounting on a trailer. The extra-large, tilt-out, fuel tank provides hours of continuous cleaning. The PDHW has loads of additional options to make it the perfect machine for any job including off-shore oil rigs.
As with all Landa models, the PDHW comes certified to the rigid UL-1776 safety standards, featuring: 24-inch hose guard for burst protection, thermal pump protector, high-temperature shutdown to prevent super-high heat buildup, and rupture disk to vent any buildup of excessive pressure in the heating coil.

    SLX/SLT Series
    Up to 9.8 GPM, and 3,200 PSI
    When it comes to heavy-duty grease or grime, most high-volume, hot water pressure washers fall short with their 150°F water. Landa's SLX, and smaller SLT, are the first power washers ever designed to deliver a high-volume flow at 200°F water, hot enough to melt the toughest of oily messes.

    The SLX delivers enough hot water flow—up to 9.8 GPM—that you can operate two spray guns at the same time! The SLX and SLT feature a top-of-the-line, belt-drive Landa Pump with 7-year warranty and low RPM for extended life, as well an extra-large Heating Coil made of cold-rolled, 3/4” Schedule 80 steel pipe in to a 5-year warranty. Gasoline-powered Honda Engines, or water-cooled, diesel-powered Kubota Engines all come with keyed electric starter for easy start-up and protection against unauthorized use. The extraordinarily rugged frame is made of 2-by-4-inch box steel with an all-metal power platform cushioned by 10 vibration isolators to minimize frame stress.
    The SLX/SLT is heated by a high-efficiency Landa Surefire or Beckett burner with adjustable numbered dial-in air flow. The 3/4" heating coil is amazingly efficient due to its unique “breathing” design so it heats quieter while promoting optimum heat exchange. The SLX/SLT has a remarkably compact footprint, is certified to UL-1776 safety standards, is pre-plumbed for drawing water from an auxiliary tank, has six forklift guides for portability and the control panel is ideally positioned for curb access when the unit is mounted on a trailer or truck bed.
