Insulated walk-in cooler doors

Insulated walk-in cooler doors are a kind of swinging Cold Storage Door with excellent thermal insulation. Such Cool Room Doors can be seen in almost every cold room, cooler storage or chiller warehouse. The purpose of walk-in Cold Store Doors is mainly for workers to pass as human entrance. The door structure is quite simple and there is no need maintenance for daily use. Compared with sliding type cooler door, wall in cooler doors no need any space around it to install. So for any area or corners of your cold room, you can easily install a walk in cooler doors. 

Material of door panel can be standard powder coated galvanized steel, or premium food-grade 304 stainless steel. 

Excellent thermal insulation

Door panel of insulated walk in cooler 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 Room Swinging Door gains excellent thermal insulation. Thermal conductivity factor: 0.018-0.023 W/(m.k). 

High airtightness

At four sides of insulated walk in cooler 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 Cool Room Doors is closed, the seal rubber will press onto the aluminum wall cover tightly, to eliminate gap between insulated walk in cooler 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 cooler door panel. It can reach B1 grade. 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 cooler 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 cooler 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
