Freezer Floor Frost Heave PreventionFreezer floor frost heave can occur when the soil beneath a refrigerated slab freezes and expands. This expansion can crack, lift, or damage the concrete floor and create costly problems for doors, equipment, and building operation. Thermalinc designs electric heat cable frost heave prevention systems that maintain the subgrade above freezing and include temperature monitoring, circuit protection, alarms, and controls. Thermalinc provides complete freezer floor heating system design, including heat cable layout, conduit layout, electrical requirements, temperature monitoring, and control panel design. |

How Electric Heat Cable Prevents Frost HeaveHeat Cable Frost Heave systems provide better monitoring and control, with less maintenance than Air or Glycol systems. Self-regulating heat cable automatically adjusts wattage as temperatures change, always providing the correct output to maintain 50°F — heating the ground beneath the floor, not the floor itself.

Freezer Floor Heating System DesignFloor layout is one of the biggest reasons customers come to us in the first place — most facility owners, contractors, and even project engineers don't have in-house experience designing a frost heave prevention floor. We handle it start to finish, not just a drawing handed off at the beginning. Design & quoting

Electric Heat Cable vs. Glycol Frost Heave SystemsElectric heat cable and hydronic glycol are the two common approaches to freezer floor frost heave prevention. Here's how they compare:

Freezer Floor Controls and MonitoringEvery Thermalinc freezer floor system can be equipped with PLC-based control and monitoring designed to detect circuit faults, monitor floor temperature, record events, and provide local alarms. Every circuit gets its own breaker, GFI protection, and far-end voltage sensing; the floor itself is monitored independently; and every fault is logged with its location and a built-in troubleshooting guide.
See the full breakdown.
Per-circuit protection, alarming, the operator display, and special features like BMS interlock and peak setback — all explained in detail. Controls and Monitoring, in full →
