Building Frost Heave Prevention Systems for over 40 Years!
Freezer Floor Freeze Protection
Design:
Heat Cable Frost Heave Systems provide better monitoring and control, with less maintenance than Air or Glycol systems.
Self-regulating heat cable is uniquely designed to suit frost heave prevention systems.
Self-regulating cable seeks to provide the proper wattage as the heat increases and decreases.
Always providing the correct wattage to maintain 50 degrees F. The result is a very efficient system with built in safety.
The cable is designed to heat the ground not the floor of the freezer. Freezers pull the heat out of the floor, and the cable replaces this heat loss.
Usually a new floor starts with base or hard pack, the 3/4" rigid conduit is usually laid onto the base (minimum of 1" from below insulation) and filled with aggregate.
Aggregate can be any standard non insulating fill material, rock, gravel, sand or even a concrete sub-slab.
Following the aggregate is a vapor barrier along with the insualtion which is usually 4 to 6" thick.
