Hinged cold room swing door

Hinged cold room Steel Swing Doors, are in simple single-leaf or double-leaf deisng, suitable for all kinds of cold rooms, cooler rooms, refrigeration warehouse or freezer rooms. Such Cold Storage Door is widely chosen by clients from food industry, pharmaceutical industry, and cold chain logistics. Made from double skin sandwich panel, it has excellent thermal insulation performance and effectively reduce heat loss and electric energy cost for a cooler or cold room. Different from sliding type cold room doors, it is mainly installed in areas of human passing openings, rather than vehicles traffic area. 

Excellent thermal insulation

Door panel of cold room hinged Steel Swing Doors is thick double layer structure sandwich panel. Middle is filled with polyurethane foam. Total Thickness available for 75mm, 100mm, and 150mm. Density of filling PU foam reaches 45kg/m³, and with closed porocity ≥95% . Thus it gains excellent thermal insulation. Thermal conductivity factor: 0.018-0.023 W/(m.k). 

High airtightness

At four sides of cold room hinged swing door leaf, there are double tooth EPDM seal rubber.  On left side, right side and top lintel of door opening, there are aluminum profile wall cover. It is to be fixed at the surface of wall, and facing the seal rubber. Thus when the Cold Storage Door is closed, the seal rubber will press onto the aluminum wall cover tightly, to eliminate gap between cold room sliding door and cold room wall. This minimize air and heat leakage through the hinged cold room swing door.

Fire retardant 

Filling PU foam is specially treated with proportion of fire-resist chemical agent. This obviously improve fire retardant performance of cold room sliding door panel. It can reach B1 grade. This is very beneficial for fire protection safety in cold rooms. 

Rust-proof in humid cold rooms

Huge temperature difference in cold rooms brings heavy humidity with a much vapor forming in every minute. So steel material is easy to rust in cold rooms. Kenvo cold room hinged swing door panels are covered with powder coated galvanized steel or 304 stainless steel. So it is double protected by both painting and galvanized layers. Top track and frames are made from aluminum profile, with excellent rust-proof capacity. 

Heater to avoid freezing

Such heating belt is intelligent self-limiting-temperature wires which will automatically control the temperature within 60-70℃, to warm up the edge of cold room swing door, to avoid freezing and ice. Because of self-limiting ability, it avoid risk of overheating causing fire accidents. 

Power supply: 1-phase 220±10%V，50/60HZ.

Easy to open and close by hand
