FROSTHOG® = How To Thaw Frozen Ground

FROSTHOG® is your answer for SAFE, CONVENIENT, CLEAN & EFFICIENT ground thawing equipment allowing wintertime hand exposing of pipeline crossings, utility lines, graves, basement foundations and more.

The FROSTHOG® operates on the principle of efficiently igniting and burning propane gas in a u-shaped tube. Maximum heat is achieved through the use of a patented “Fire Tube Energy Saver” installed in the combustion chamber. This device confounds the flow of the air/gas mixture through the tube thereby forcing all heat to the inside walls. In turn, this heats the outside of the tube to its maximum capability. A ceramic insulated housing encases the heat tube, and when this housing is lowered to the surface to be thawed, an extremely high percentage of total heat is directed downward. Very little heat is lost to the atmosphere. Operating the FROSTHOG® at 400° C will obtain maximum efficiency.

TIPS FOR WORKING IN FROZEN GROUND

Frozen ground is a hard reality in much of Canada and northern USA. Contractors working in these cold climates need to be ready for whatever conditions they may face. Having the proper tools before arriving on site will reduce downtime on your project. Here’s some tips for excavators working in frozen ground:

Ensure you have proper low temperature oils in your excavator and attachment tools.

Inspect excavator boom, stick, and attachments for cracks before moving the equipment to site. Repairs in the field are often much more costly, cause unplanned delays, and are typically lower quality than repairs made in a shop with the most appropriate conditions and tools on hand.

Stock a sufficient supply of wear parts on site. Frozen ground is more abrasive and frigid temperatures increase the likelihood of cracked hoses and broken seals.
