Modular cold rooms are one of the smartest solutions for businesses that need reliable, flexible, and energy-efficient temperature-controlled storage. Whether you’re in food service, pharmaceuticals, floristry, or logistics, building your own cold room can seem like a big task—but with the right guidance, it’s more achievable than you might think.
At ColdSafe, we specialize in designing and constructing modular cold rooms for a wide range of industries. Whether you want to build it yourself or leave it to the experts, we’re here to help. Below is a step-by-step guide to help you understand what it takes to build a modular cold room.
Step 1: Define Your Requirements
Before starting any construction, you need to clearly define:
Purpose: Chilled (0°C to 5°C) or frozen (-18°C and below)?
Size: What are your current and future storage volume needs?
Location: Indoor or outdoor? Will it be permanent or temporary?
Power Source: What electrical infrastructure is available?
Access Needs: Think about door size, shelving, and traffic (people, trolleys, forklifts).
🧊 ColdSafe Tip: Consider installing slightly larger than your current need to allow room for growth.
Step 2: Choose the Right Insulated Panels
The core of a modular cold room is its panels. These are typically made of high-density polyurethane foam sandwiched between steel sheets (galvanized, pre-painted, or stainless steel).
Thickness: Usually 80–150mm, depending on the required temperature range.
Finish: Food-grade, corrosion-resistant materials are best for hygiene.
Interlocking System: Panels should lock tightly to prevent air leakage.
🧊 ColdSafe Tip: We offer panels in various finishes and thicknesses to suit any application, from commercial kitchens to pharmaceutical warehouses.
Step 3: Construct the Cold Room Frames
Begin by installing the floor panels (if required), then work your way up:
Lay out the base frame.
Install wall panels by interlocking edges.
Fit corner pieces and ceiling panels.
Seal all joints using food-safe silicone or gasket tape for airtightness.
This stage can be done relatively quickly with two or more people and some basic tools.
Step 4: Install the Refrigeration Units
The heart of the cold room is the cooling system. You’ll typically choose between:
Monoblock units (integrated): Easier to install, good for small to medium rooms.
Split systems (separate condenser and evaporator): More powerful, ideal for larger or hotter environments.
Installation involves:
Mounting the unit (usually through a wall panel or on the ceiling).
Connecting electrical supply and drainage.
Setting temperature controls.
🧊 ColdSafe Tip: Our engineers can recommend and install the perfect system for your temperature range, energy efficiency, and usage.
