I have an enquiry for doors to be mounted in -20 C cold room. Are the door motors designed to operate in these temperatures? We are in Durban, South Africa where humidity levels are high and ice build-up is a problem.
The solution is to fit the doors OUTSIDE the cold rooms in ambient. We can offer an insulated door (3.5mm) with excellent seals that will mitigate to a degree the ice build up.
Let me have some details (sizes, location etc) and I will get you a quote.
