Industrial Pressure Washers for Oil, Gas & Mining Industries

Unimanix offers rugged, high-quality pressure washers to the oil, gas and mining industries that require cleaning of their tanks, large haul trucks and any heavy equipment caked with mud, clay, ice, grass or muck. Unimanix builds robust cleaning equipment to keep oil fields operating at peak conditions and quickly de-ice offshore equipment and rigs to ensure staff safety.

Hot & Cold-Water Pressure Washers

Robustly designed for heavy industrial applications such as mining and oil field services, our electric engine pressure washers are great for cleaning large haul trucks, steel tracked vehicles, or any heavy equipment caked with excess grease, oil, sludge, and other substances. Unimanix offers standard electric hot water pressure washers, making them perfect for underground use.

For trucks and heavy equipment applications, the Unimanix gas pressure washer is a popular choice for its mobility and ability to withstand daily use. With larger engines, these pressure washers will get those large dirty jobs done quickly and clear out the most embedded grime.

All our hot or cold-water pressure washers include a steel-braided high-pressure hose, spray wands with a quick-connect coupling, and a heavy-welded steel frame and chassis that resist corrosion for years. Unimanix hot and cold-water pressure washers feature industrial pumps that are leak-free. These pumps require minimal maintenance requirements that can efficiently remove mucky fluids using a wide range of pressures and flows.

Wash Bay Cleaning System & Portable Wash Pad

Not only will Unimanix work with you to map out your washing requirements, but we will also help you design the pressure washer set-up for your wash bay. You can count on our experience because we’ve custom-built pressure washing systems for over 100 wash bays. Fully automated, our convenient drive-thru wash bay is the right choice for your truck and fleet washing. We can design a wash bay large enough to accommodate a vehicle such as a full-sized tractor. In other words, when you need to clean any mode of transportation, we will make sure you can clean it!

Working with Unimanix, we will help you select a water recovery system that will allow you to reuse water, so there is less water usage and, at the same time, protect the groundwater from waste materials while meeting most municipal and environmental regulations.

Safe Remote, Mobile & Truck Mounted Pressure Washers

The mobile pressure washer with recovery and reuse water system is becoming increasingly popular as more environmental regulations restrict wash-water runoff from entering and soiling the environment. We will help build one as per your specifications that can include a custom-mounted pressure washer on a dual-axle trailer with a self-contained diesel-powered hot water pressure washer and optional accessories, such as mounted hose reels.

You won’t have anything to worry about should your pressure washer dealer be miles away. We will work with you to customize your Unimanix pressure washers with superior features such as:

  • Quality components such as CAT or AR pumps
  • Wide range of hoses & nozzles
  • Design excellence of a Honda or Kohler engine

Plus, depending on the pump selected, it can include a 7-year limited warranty! Your Unimanix territory manager will go over these details to ensure you get the right unit. Whether you choose a mobile pressure washer, truck-mounted unit, portable wash pad system or on-site cleaning system, Unimanix will work with you to design and build the right machine for your application.


Unimanix carries a wide range of pressure washer accessories that can do both rinsing and application of foam cleaners for fast cleaning applications on rigs, tanks, trucks and heavy equipment. You will also find the right accessories for those "hard-to-clean" areas.

  • Pivot Hose Reels
  • Extra-Long Hoses
  • Wired & Wireless Remotes
  • Foamer Attachments
  • High-Pressure Turbo Nozzles
  • Wand Extensions
