Overview
A cold room is an insulated enclosure built from PUF (polyurethane foam) sandwich panels with a refrigeration system sized to hold a fixed temperature. We supply and install cold rooms for hotel kitchens, restaurants, dairies, food processing units, pharmaceutical stores, hospital blood banks and vaccine storage, along with deep freezers for smaller frozen storage needs.
Chiller rooms and freezer rooms
Cold rooms fall into two groups. Chiller rooms hold roughly +2 to +8 degrees Celsius for vegetables, dairy, medicines and vaccines. Freezer rooms hold roughly -18 to -25 degrees Celsius for frozen meat, ice cream and frozen foods. The temperature decides the panel thickness, the type of door, floor insulation and the refrigeration unit, so it is the first thing we fix with the client.
How we size a cold room
The refrigeration load depends on the room size, the quantity of product loaded each day and its incoming temperature, how often the door is opened, lighting, people working inside and the outdoor temperature where the condensing unit sits. A room that is loaded with warm product every evening needs far more capacity than one used for steady storage. We calculate this before selecting the unit, so the room pulls down to temperature in the expected time without the compressor running continuously.
Installation details that matter
- PUF panels with cam-lock joints and sealed corners, with insulated flooring for freezer rooms to stop the floor slab from freezing
- Hinged or sliding insulated doors with heater strips on freezer doors, plus strip curtains to cut warm air entry
- Evaporator placement that gives even air throw without blowing directly on stored product
- Defrost arrangement and drain line heating on freezer rooms
- Digital temperature controller and, for pharma and vaccine stores, a temperature logger or alarm
Maintenance
Cold rooms fail mostly because of iced evaporators, blocked condenser coils, damaged door gaskets and refrigerant leaks. Under AMC we clean coils, check defrost operation, door seals, refrigerant pressures and controller calibration on a fixed schedule.
Where it is used
Hotel and restaurant kitchens, dairies, food processing units, pharmaceutical and vaccine stores, hospital blood banks, supermarkets and floriculture.

Typical technical data
| Chiller room range | About +2 to +8 degrees Celsius |
|---|---|
| Freezer room range | About -18 to -25 degrees Celsius |
| Panel insulation | PUF sandwich panels, thickness selected for the temperature |
| Refrigeration | Air-cooled condensing unit with ceiling or wall evaporator |
| Control | Digital controller, defrost timer, optional temperature logger |
Figures are typical ranges for equipment we supply. Final selection depends on the heat load calculation and the manufacturer's data for the chosen model.

Frequently asked questions
What temperature can a cold room hold?
A chiller room usually holds between +2 and +8 degrees Celsius for vegetables, dairy and medicines. A freezer room holds between about -18 and -25 degrees Celsius for frozen food. The temperature decides the panel thickness, door type and refrigeration unit.
How is the size of the cold room refrigeration unit decided?
By a load calculation that considers the room volume, how much product is loaded each day and at what temperature, door openings, lighting, people working inside and the outdoor temperature. Product loading is usually the biggest factor.
Do you supply Daikin and Voltas cold room units?
Yes. We supply and install cold room refrigeration from brands including Daikin and Voltas, along with PUF panels, doors, controls and electrical work.
Can a cold room be used to store vaccines or medicines?
Yes, provided it holds a stable +2 to +8 degrees Celsius with a reliable controller, a temperature logger and an alarm, and preferably a standby refrigeration unit for critical stock.
Do you also supply deep freezers?
Yes. For smaller frozen storage needs where a walk-in room is not justified, we supply commercial deep freezers.
