1. General Information
Q1: What exactly is a cold room?
A cold room (also known as a walk-in cooler or walk-in freezer) is a large, refrigerated enclosure or room used for storing perishable goods at a controlled, low temperature. Unlike a standard refrigerator, a cold room is large enough to walk into and is typically custom-built to fit a specific space and meet specific temperature requirements for commercial or industrial use.
Q2: What is the difference between a Chiller Room and a Freezer Room?
The primary difference is the operating temperature range.
-
Chiller Cold Rooms (or Walk-in Coolers)typically operate at a temperature between0°C and +8°C (32°F and 46°F). They are used for storing fresh products like fruits, vegetables, dairy, flowers, and prepared foods.
-
Freezer Cold Rooms (or Walk-in Freezers)operate at sub-zero temperatures, usually between-18°C and -25°C (-0.4°F and -13°F). They are designed for the long-term storage of frozen goods such as meat, fish, ice cream, and medical supplies.
Q3: What industries typically use your cold rooms?
Our cold storage solutions are versatile and essential for a wide range of industries, including:
-
Food & Beverage (Restaurants, Hotels, Catering)
-
Supermarkets and Grocery Stores
-
Food Processing and Distribution Centers
-
Pharmaceutical and Medical Laboratories
-
Florists and Horticulture
-
Breweries and Wineries
-
Mortuaries
2. Technical Specifications & Customization
Q4: Are your cold rooms custom-built or available in standard sizes?
We offer both. We have a range of standard-sized modular cold rooms for quick deployment, but our specialty is creating fully customized solutions. We can design and build a cold room to your exact dimensional requirements, maximizing your available space and meeting your specific operational needs.
Q5: What are the insulated panels made of?
Our cold room panels are high-performance composite panels, typically consisting of a core of Polyisocyanurate (PIR) or Polyurethane (PUR) foam insulation, sandwiched between two layers of pre-painted, food-safe steel. This construction provides excellent thermal insulation (high R-value), structural rigidity, and a hygienic, easy-to-clean surface. Panel thickness varies depending on the required temperature (thicker panels are used for freezer rooms).
Q6: Do I need an insulated floor for my cold room?
It depends on the application and location:
-
Chiller Rooms:For chillers built on a ground-level, insulated concrete slab, a separate insulated floor is often not necessary. However, for installations on upper floors or uninsulated surfaces, an insulated floor is highly recommended to prevent condensation and improve energy efficiency.
-
Freezer Rooms:An insulated floor ismandatoryfor all freezer rooms. Without it, the sub-zero temperatures can freeze the ground beneath the concrete slab, causing "frost heave" which can lead to severe structural damage to your building's foundation.
Q7: What types of doors are available?
We offer several door options to suit different workflows and space constraints:
-
Hinged Doors:The most common and cost-effective option, suitable for most applications.
-
Sliding Doors:Ideal for areas with limited swing space, such as busy corridors. They provide a wider opening for pallet jacks or trolleys.
-
Optional Features:We can also include heated door frames (essential for freezers to prevent freezing shut), viewing windows, and kick plates for enhanced durability.

3. Installation & Site Requirements
Q8: What are the site requirements for installing a cold room?
To ensure a smooth installation, your site should have:
-
A Level Floor:The surface must be solid and perfectly level to ensure the panels align correctly and the doors seal properly.
-
Adequate Power Supply:A dedicated, correctly rated electrical supply is required for the refrigeration unit. We will provide the specific power requirements during the quotation stage.
-
Sufficient Ventilation:The external condensing unit (the "motor") generates heat and requires adequate airflow around it to operate efficiently. It should not be placed in a small, unventilated room.
-
Clear Access:Ensure there is a clear path for our technicians to bring in the large panels and equipment.
Q9: How long does the installation process take?
The installation time varies based on the size and complexity of the project. A small, standard-sized modular cold room can often be installed in one to two days. A large, complex, or custom-built cold room may take several days or more. We will provide a projected timeline with your formal quotation.
4. Operation & Maintenance
Q10: What are the typical running costs of a cold room?
The primary running cost is electricity consumption. This is influenced by several factors:
-
The size of the cold room.
-
The insulation quality (panel thickness).
-
The frequency of door openings.
-
The ambient temperature outside the cold room.
-
The efficiency of the refrigeration system.
We design our systems for maximum energy efficiency to help keep your operational costs as low as possible.
Q11: How do I maintain my cold room to ensure its longevity?
Regular maintenance is key. We recommend:
-
Daily/Weekly:Keep the interior clean and organized. Ensure there is no debris blocking the evaporator fans. Check that the door seals completely.
-
Monthly:Clean the door gaskets. Listen for any unusual noises from the refrigeration unit.
-
Annually:Schedule a professional service with a qualified refrigeration technician. They will check refrigerant levels, clean the condenser coils, test all electrical components, and ensure the system is running at peak efficiency. We offer service and maintenance contracts for your peace of mind.

5. Pricing & Ordering
Q12: How much does a cold room cost?
The price of a cold room is not "one-size-fits-all" and depends entirely on your specifications. The key factors that determine the cost are:
-
Dimensions:Length, width, and height.
-
Temperature:Chiller or freezer application.
-
Insulation:Thickness of the wall, ceiling, and floor panels.
-
Door:Type (hinged/sliding) and size.
-
Refrigeration System:The size and type of the cooling unit.
-
Additional Accessories:Shelving, lighting, temperature alarms, etc.
Q13: What information do you need from me to provide an accurate quote?
