DefrostSock
Quick and efficient unit defrosting
Specifically designed to make it easier to remove frost from the evaporator.

Up to 2× faster defrosting, 50% time and energy savings
Defrost Socks are specialised ducting designed for defrosting evaporators in cooling and freezing equipment. Their use makes the defrosting cycle up to twice as fast, saving up to 50% in time and energy. This results in more reliable, efficient, and cost-effective operation. In addition, they are made from an exceptionally durable textile with a 10-year warranty.
How they work and where they’re used
The principle is simple: during defrosting, heat is released inside the evaporator, which would otherwise escape into the space. Defrost Socks retain this heat directly at the evaporator, significantly speeding up the defrosting process. Once the unit is turned off, the ducting automatically closes to prevent heat loss.

This system is an essential accessory for all freezer and cooling chambers where fast and regular defrosting is required. It’s ideal for restaurants, meat and food cold stores, and fruit or vegetable warehouses – in short, anywhere speed, operational stability, and minimal downtime are key.
Innovative technology
Defrost Socks use a unique combination of two key elements:
An airflow control cord that allows precise adjustment of external pressure loss, directly influencing the defrosting speed. |
Three Velcro straps that enable the ducting to quickly collapse after the evaporator is turned off, retaining heat at the source as efficiently as possible. |
These technical details make the defrosting process faster, more energy-efficient, and more reliable than conventional solutions.
