  • Advantages of a Hot Water Pressure Washer

    Simply by heating up the water, a hot water pressure washer delivers dramatically improved cleaning power compared to a cold water machine. Hot water pressure washers are especially useful for cleaning sticky, greasy, or oily surfaces, because they will loosen the dirt much faster without the large amounts of soap, detergent, or other cleaning chemicals that must be used with a cold water system.

  • Hot Water Pressure Washer Applications

    A hot water pressure washer is essential for any cleanup job involving a sticky, greasy, or oily mess, as well as for applications where a surface must be sanitized. With a variety of models available, including self-contained mobile units with gas, diesel, or electric power, Hydro Tek hot water pressure washers can go anywhere and clean anything. Some common applications include heavy equipment cleaning, vehicle cleaning, graffiti removal, restaurant hood vent cleaning, and livestock facility cleaning.

Quality & Innovation Since 1985

Hydro Tek

From simple beginnings in 1985, Hydro Tek has grown to become the most trusted name in the pressure washer manufacturing industry.

How did we do it? By continually focusing on quality and reliability as the key to customer satisfaction, and by incorporating the latest technologies into our design and manufacturing processes.

By 1991, we were using computer-aided drafting systems to refine our product designs and improve efficiency. In 1997, we brought the power of computers to the shop floor by incorporating laser-cutting and other CNC manufacturing machinery, and in 2001 we began focusing on improving efficiency through the latest manufacturing techniques. The end result has been superior products delivered at a superior value to our customers. Through the next decade, we look forward to fulfilling our vision of making our products the "obvious choice" for all your industrial and commercial cleaning needs.
