Safety-Certified, Patented Ground Frost Removal Equipment

Why FROSTHOG® Ground Frost Removal System?

THE ANSWER for any excavation in frozen ground!

For hand exposing pipeline crossings, utility lines, graves.

SAFE, CONVENIENT, CLEAN, and EFFICIENT!

The FROSTHOG® is easily transported on its own self-loading trailer.

It 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.

FrostHog Ground Thawing

The FROSTHOG® is a simple machine that is easy to operate. It can be pulled to the jobsite, fired up, and left unattended during the thawing process. It runs quietly, is transported on its own wheels and can be easily placed in the desired position for work. Depending on soil conditions most frost is removed within 24 – 48 hours, which will consume approximately 2‐100 lb bottles of propane in 24 hours. Asphalt does not affect the frost removal process. By removing all the moisture, refreezing does not take place for an extended period of time, should there be a delay in hand exposing. If soil is not disturbed the thawing process will continue.

SAFETY

All burner controls and propane valves are enclosed to eliminate vandalism. The hood is insulated to maintain high interior temperatures, yet leaving the exterior cool to prevent accidental burn injuries. There is no open flame – all units are equipped with flame arrestor cells, safety valves and automatic gas shut‐offs, making the FROSTHOG® explosion‐proof for use in residential and/or hazardous areas.

SAVINGS

Unlike costly water, steam, and vacuum trucks that only expose a small area, the use of a 12 ft. FROSTHOG® will allow 5 – 6 feet of hand excavating on each side of the major pipeline. Therefore exposing by hand the possibility of any other pipelines or utility lines and keeping within the guidelines set forth by the Government and pipeline companies.

For more savings, the FROSTHOG® can be converted to natural gas when available.
