Frost lock

These industrial sectional doors offer excellent thermal insulation down to -23°C and can optionally be made fire-resistant.

Frost Lock is the ideal solutions for applications where negative temperatures prevail on both sides of the door, such as freezer warehouses, cold corridors, and deep-freeze storage areas within temperature-controlled production or logistics facilities. These isothermal doors minimise energy loss and enhance fire safety in temperature-controlled environments. They integrate seamlessly into a comprehensive fire compartmentation system, physically separating cold zones to slow fire propagation and safeguard the continuity of critical processes.

For even more extreme environments, we developed Cryo Lock, designed for cryogenic applications down to –60 °C, where conventional systems are no longer sufficient.
