— How To Install A Cold Room? —
This video mainly teaches you how to install a small cold room, including polyurethane sandwich panels, cold room door, condensing unit, air cooler and related accessories.
We are a manufacturer with 25 years of cold storage production experience. It has provided professional refrigeration solutions for more than 30 countries and regions around the world.
Step 1: Panel Installation
Install the cold room panels using camlock connections.
Ensure a secure fit and use sealant to seal any gaps.
The core material of the panels can be PPGI, stainless steel, or aluminum.

Step 2: Door Installation
Install the cold room doors, which can be hinged or sliding.
Floor panels are usually installed first, followed by wall panels.
Roof panels are added once the floor and wall panels are in position.
Pay attention to the insulation and sealing of the doors for better efficiency.

Step 3: Air Cooler Installation
Consider the size of the air cooler when storing roof panels.
Secure the air cooler onto the roof panels.
Connect the air cooler to the compressor unit using copper pipes and insulation.
Connect various components like solenoid valves, expansion valves, pressure controls, and electrical connections to ensure proper functioning.

Step 4: Temperature Control
Install a temperature controller, which should receive power from the main source.
This controller manages the temperature, compressor operation, and lighting within the cold room.

Step 5: Air Curtain (Optional)
Install an air curtain above the door to maintain temperature control.
The power for the air curtain usually comes from the temperature controller.
Step 6: Final Checks and Testing
Ensure that all components are properly connected and functional.
Verify that the temperature control system works as intended.
Make any necessary adjustments to achieve the desired temperature levels.
Building a cold room involves careful planning, installation of panels, door sealing, air cooler installation, temperature control setup, and testing. Proper installation and insulation are essential to ensure efficient cooling and temperature control. The process should be carried out by experienced engineers and technicians to guarantee the cold room's functionality and effectiveness.
