  • Clears compressor heads of dirt and foreign matter.
  • Quickly cleans water cooled compressor heads.
  • Protects cooling jacket from blockage.
  • Connects to any water source for cleaning.

Design Features

  • All components are stainless steel for corrosion resistance and durability.
  • Cleaning tool fits into standard DL2.1 GURU Plug Type CH flanged body and GURU CHS.
  • Provides four water jets to clean out the compressor head cooling jacket.

Installation & Operation

Install a ball valve shut off valve at the end of a pressurized water source and hose.

Using a thin head 7/8” wrench (available in a kit) against the wrench flats on the nose of the cleaning tool to hold against rotation, tighten the hose to the cleaning tool. The inlet threads to the tool are 3/8” NPT male pipe thread.

With the engine off (no water pressure in cooling system), remove the GURU® CH or CHS freeze protection cartridge by turning counterclockwise about one third turn. Insert the cleaning tool into the GURU CH or CHS body by pushing inward and turning one third turn clockwise.

Open a valve downstream of the compressor head which will allow the cleaning water and dirt to be flushed out of the system. Open the water supply shutoff valve to allow the water jets of cleaning tool to clean the compressor head.

After the cleaning is completed, turn off the water by closing the shutoff valve, remove the cleaning tool by rotating counterclockwise about one third turn, and replace the GURU Plug cartridge to maintain freeze protection. Close the drain valve used to discharge the dirt from the system prior to refilling with cooling water.

Water-cooled compressor heads on locomotives are known to accumulate dirt and other foreign matter which eventually reduces the compressor’s efficiency. If left un-cleaned, the cooling jacket in the head can become completely blocked by foreign matter. To address this problem, ThermOmegaTech offers the compressor head cleaning tool. Many water-cooled compressors are protected against freezing by a GURU® Plug Type CH freeze protection valve. The compressor head-cleaning tool allows insertion of the cleaning nozzle into the same flanged body as the GURU® Plug Type CH or CHS. A shutoff ball valve should be installed at the inlet of the cleaning tool along with connection of the tool to a pressurized water source.
