Performance
Thaw and Cure
performance in the field is affected by a wide range of factors to include soil type,
density of frozen ice in the soil, hose spacing, thermal rating of the covering insulating blankets, and
ambient temperatures.
Heat
performance in interior spaces is also affected by several factors to include outside ambient
temperatures, heat loss through walls and ceiling, and the volume of the space to be heated.
In general, with proper hose spacing and adequate insulation, the operator should be able to THAW
about one foot of soil per day. Consult our Thawzall Technical Support personnel with questions
regarding proper hose spacing. 888.757.3545
HIGH ALTITUDE ADJUSTMENTS
If your Thawzall is to be used at altitudes above 5,000 feet (1,530 meters), the burner nozzle and air intake settings must
be changed to accommodate lower oxygen levels at higher altitudes.
