Insulated cooler sliding door

Insulated cooler sliding doors can be made in manual type and also automatic type. With a top aluminum profile track, cooler sliding door leaf can slide left and right smoothly to open and close the door. Cold Room Doors leaf is made from steel sandwich panel. Double skin steel sheet at surface can be powder coated galvanized steel or 304 stainless steel. In the middle of steel sheet, it is filled with high density polyurethane foam, which is an excellent thermal insulation material, with R value.  When installed in cooler rooms with big temperature difference between rooms, insulated cooler sliding doors will reduce the heat transduction to minimum, and maintain low temperature inside the cooler room. And for lower temperature cooler room, thicker panel Cold Storage Door are available to fit it. 

Excellent thermal insulation

Double skin structure sandwich panel. Thickness optional 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 insulated cooler room sliding door leaf, there are double tooth EPDM seal rubber.  On left side, right side and top lintel of wall opening, there are aluminum profile wall cover. It is to be fixed at the surface of wall, and facing the seal rubber. Thus when door is closed, the seal rubber will press onto the aluminum wall cover, to reduce gap between insulated Cool Room Doors and cold room wall. 

Stable and user-freindly driving system

Intelligent control system of insulated cooler sliding door can be easily set for running parameters, like speed, safety protection , and auto-close mode. Drive motor power rating is DC36V, safe low voltage to avoid human hurting in case of , impvoing protection of human from electricity. Motor output torque is flexible adjusting according to load weight, to realize silent and smooth running. 

Operation method: two control buttons and two remote control for each door. 

Door power supply: compatible at the same time for both 1-phase 220±10%V and 1-phase 380±10%V, 50/60HZ.

Fire retardant 

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

Rust-proof in humid cooler rooms

Big temperature difference in cooler rooms create big humidity with a lot vapor generated every minute. So this make steel material easy to rust in cold rooms. Kenvo insulated cooler room sliding door panels are covered with powder coated galvanized 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. 

Heating device to avoid freezing

For low temperature cooler room, we equip the insulated cooler room sliding 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 cooler room sliding door, to avoid freezing and ice.

Easy to open and close by hand

A long crank shape handle on insulated cool room sliding door leaf, and a steel pivot block on the frame. When opening the cooler room door by hand, only need pull the handle with little force. 

Emergency exit safety protection

There is a possibility that worker is locked inside the cooler room. In such case, it is very dangerous for human life because of low temperature. Kenvo insulated cooler room sliding doors adopt a special emergency release lock. Even the door is locked from outside, inside people can directly open the cooler door by pulling emergency exit bar. This protect human life well.

Besides above Cold Room Sliding Door, we also produce some other kinds of doors fit for cold stores, including cold room rapid doors, Insulated Sectional Overhead Doors
