Cold Room Door

Cold room door (Also called cold storage door) refers to a door that is specially installed in a freezing environment such as a freezer or a chiller for thermal insulation and airtightness. Cold Room insulation design is mainly to block the heat transfer between the cold room and outside. High-quality cold room door will greatly enhance the thermal insulation effect of the cold room. And generally coordinate with air curtains, cold room door can effectively reduce the cooling loss of cold room.

Cold Room Door Material

There are 2 methods to produce cold room door core:

#1. Polyurethane (PU) Injection

Use PU pressure injection molding machine to produce. The polyurethane structure is dense, no shrink, and the door is smooth and beautiful.

#2. Thermal Insulation Board

PU thermal insulation board not only has a high strength but also has good thermal insulation effect; There is a safety device on the cold room door to escape easily once people are accidentally closed in the cold room.

Both side surfaces use stainless steel, color steel, alluminum alloy,etc.

Sliding door

The guide rails are made of rust-proof aluminum alloy, and have an anti-icing system. All screws are galvanized, with 2.0mm thickness stainless steel (or custom your material) edge seamless welded door frame, durable and non-deformation.

How to Choose A Right Cold Room Door?

Due to the temperature difference between inside and outside of the cold room, when open the door, the hot air passes through the gap to generate strong convection, resulting in cooling loss.

The amount of hot air entering the cold room is related to the height and width of the door, the temperature difference between inside and outside of the room, and of course the time and frequency of opening the door.

You should select a cold room door which opens and closes quickly, meanwhile had better set an air curtain.

#1. Select according to the temperature

If you choose a thinner thickness door for low-temperature cold room, it won’t achieve the ideal insulation effect, and will frost the door, which will damage the door.

Chiller temperature is -15℃~5℃, you can choose 100mm (10cm) thickness door; Blast freezer is -30℃~-45℃ you can choose 150mm (15cm) thickness door.

According to the temperature difference, the cold room door thickness can select from 75, 100, 120, 150, 180, 200mm.

Mobile cold room

#2. Select according to size

The cold room door size is not fixed, can be made of various sizes according to customer requirements. It can be divided into manual or electric single-opening, double-opening sliding door or hinged door,please choose the appropriate size and type of cold room door according to cold room application.

For example, if a forklift is required to enter and exit, you should choose an electric cold room door to facilitate entry and exit. For small cold room, only few people enter and exit, so can choose manually operate door.

Meanwhile, when installation, you must also understand the specific location of the cold room door. If choosing a sliding door, you need to have enough space to place the slide.

#3. Select according to the material 

The cold room door frame can be made of  aluminum alloy,stainless steel or PVC plastic. PVC is a poor conductor of heat, which can’t only effectively ensure a constant temperature, but also strengthen the load-bearing capacity of the door frame and guide rails. It can still be used at low temperatures.

Cold room door wrapping adopts stainless steel seamless welding or glass fiber reinforced plastic (FRP) which is impermeable, strong heat insulation and corrosion resistance.

The inner core of cold room door is generally made of polyurethane (PU) or XPS material. XPS has good moisture resistance, high compressive strength, moderate price, stable performance and long service life. It is the best choice for cold room insulation materials.

Checklists For Qualified Cold Room Door

#1. Cold room door should have good thermal insulation and air tightness to reduce cooling loss.

#2. Lightweight, flexible in opening and closing, with a certain strength.

#3. Have anti-freezing or anti-condensation facilities, such as add electric heating devices at the contact parts between door frame and door sealing surface.       

#4. Sturdy and durable, no deformation, anti-collision. Cold room door with powered loading and unloading equipment should provide guardrails or protective panels.

#5. Set up emergency safety lights, distress signal and self-opening equipment in warehouses where operators are easily locked by mistake. Electric, pneumatic and hydraulic automatic door shall provide false closing protection.

#6. Set appropriate size door opening to facilitate loading and unloading operations, meanwhile reduce the intrusion of external heat and moisture when opening the door. In addition, when there are often small boxes of frozen food or beverages entering and leaving, normally should open a small door on the cold room door, which is more convenient to use and saves energy.
