Insulated walk-in freezer doors can be made in single leaf or double leaf. Flexible hinges connect door leaf and frame. It can be easily opened or closed by hand with its lockset handle.  The walk-in freezer door can be half embedded or fully embedded into cold room wall panels. Cold Room Doors can fit for your cold room wall no matter it is sandwich panel wall or PU sandwich panel wall. And thickness of panel of Cold Storage Door is optional from 75mm to 150mm, fit for different temperature cooler rooms. 

Excellent thermal insulation

Door panel of insulated walk in freezer door 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 Cold Store Doors gains excellent thermal insulation. Thermal conductivity factor: 0.018-0.023 W/(m.k). 

High airtightness

At four sides of insulated walk in freezer 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 insulated walk in freezer door is closed, the seal rubber will press onto the aluminum wall cover tightly, to eliminate gap between insulated walk in freezer door and its frame. This minimize air and heat leakage through the insulated walk in freezer door.

Fire retardant 

Filling PU foam is specially treated with proportion of fire-resist chemical agent. This obviously improve fire retardant performance of insulated walk in freezer door panel. Cool Room Doors can reach B1 grade fire rating. This is very beneficial for fire protection safety in cold rooms. 

Rust-proof in humid cooler 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 walk in freezer 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

For low temperature cold rooms, we supply the insulated walk in freezer door with all-round heating belt. Such heating belt is intelligent self-limiting-temperature wires which will automatically control the temperature within 60-70℃, to warm up the edge of insulated walk in freezer 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
