Main characters：
The insulation layer of cold storage door leaf is made of foam board or polyurethane, the panel material is color steel plate or stainless steel. The heat- transfer coefficient of it is 0.22W/m2k which has good heat insulation. The connection of door leaf, ground and frame is specifically designed and sealed with specifically made rubber bar. Low voltage and high efficient electric heater is designed around the door in order to prevent freezing of connection.
