What Is a Double Regime Cooling Unit?
A double regime cooling unit is a refrigeration solution capable of operating across different temperature ranges according to the requirements of the cold storage project.
For example, a business may initially use a cold storage room for frozen products at approximately -18°C. After the products have been shipped, the same storage area may be used for another product requiring approximately +4°C.
This flexibility can be particularly valuable for companies with seasonal or changing product ranges.
Why Choose Double Regime Refrigeration?
Businesses do not always store the same products throughout the year. A flexible refrigeration system can therefore provide significant operational advantages.
-
Flexible use of the same cold storage area
-
Suitable for changing product ranges
-
Potential reduction in the need for separate storage rooms
-
More efficient use of available floor space
-
Adaptability to different operating temperatures
-
Suitable for various food and industrial applications
Using One Cold Room for -18°C and +4°C
One of the main applications of a double regime system is the possibility of using a storage room for different temperature requirements at different times.
For example, the first loading may involve frozen products that require a temperature of approximately -18°C. After the products are shipped, the room can potentially be prepared for a second loading requiring approximately +4°C.
However, not every refrigeration unit is suitable for every temperature range. The refrigeration capacity, evaporator, condenser, compressor, controls and insulation must be evaluated together during the design stage.
Cold Room Panel Selection
The performance of a cold storage system depends not only on the refrigeration unit but also on the insulation structure. The cold room panel plays an important role in controlling heat transfer.
Panel thickness, insulation performance, joint quality and installation details should be evaluated according to the lowest operating temperature required by the project.
Therefore, comparing only the cold room panel price may not provide a complete picture of the long-term value of a cold storage investment.
Importance of the Cold Room Door
The cold room door is another important component of an efficient refrigeration system.
Frequent door opening can increase heat gain and refrigeration demand. For this reason, door dimensions, insulation, seals, hinges, locking mechanisms and operating conditions should be considered when designing a cold room.
Businesses comparing cold room door prices should evaluate technical specifications rather than selecting a door based only on the initial price.
How Are Cooling Units Selected?
Choosing cooling units based only on the cubic volume of a room is not sufficient. A proper refrigeration load calculation should consider several factors.
Room Volume
Room dimensions and total volume are fundamental parameters, but two rooms with the same volume may require different refrigeration capacities.
Product Quantity
The amount of product entering the room each day has a direct effect on the required refrigeration capacity.
Product Inlet Temperature
The temperature of the product when it enters the room is an important factor in determining the refrigeration load.
Target Temperature
A system designed for approximately +4°C has different requirements from one designed for approximately -18°C. Double regime applications therefore require careful engineering.
Ambient Temperature
Outdoor and surrounding room temperatures influence refrigeration performance and energy consumption.
Door Opening Frequency
Frequent door opening can increase heat gain and should be included in the refrigeration load calculation.
Double Regime Cold Room or Two Separate Cold Rooms?
A double regime system is not automatically the best solution for every business. The decision depends on how the storage rooms will be operated.
A Double Regime System May Be Suitable When:
-
The product range changes periodically.
-
The same room will be used at different times.
-
Available floor space is limited.
-
Operational flexibility is important.
-
Two separate rooms may not be necessary.
Separate Cold Rooms May Be Better When:
-
Different products must be stored simultaneously.
-
Products require different temperatures at the same time.
-
Two separate operating environments are required.
-
Products must be physically separated.
What Determines Cold Room Price?
The cold room price depends on the technical specifications and project requirements. There is no single price that applies to every cold room.
-
Room dimensions
-
Total storage volume
-
Panel thickness
-
Panel insulation properties
-
Cold room door type
-
Refrigeration capacity
-
Double regime requirements
-
Control system
-
Installation
-
Transportation
-
Project-specific engineering requirements
Businesses comparing the cold room cooling unit price should compare equivalent technical specifications rather than comparing price alone.
Cold Room Systems for Different Business Needs
Keskinso provides solutions for different cold storage applications. Depending on the project, businesses may consider cold room systems , refrigeration systems and modular storage solutions.
The correct system should be selected according to product type, temperature requirements, room dimensions, loading frequency and operating conditions.
Modular Cold Room Solutions
A modular cold room can provide a flexible solution for businesses that require scalable storage capacity.
Modular construction can be adapted to different room sizes and applications, making it suitable for food production, restaurants, supermarkets, logistics operations and industrial facilities.
Home Cold Room Solutions
Smaller businesses and specialized users may require compact storage solutions. A home cold room or small-scale cold storage solution can be considered where appropriate to the required capacity and operating conditions.
Portable Cold Storage and Container Cold Rooms
Where permanent construction is not practical, a portable cold storage solution may be considered.
A container cold room can also provide a practical alternative for temporary storage, logistics operations, additional capacity and field applications.
Turnkey Cold Room Installation
A successful cold storage project involves much more than installing panels and a refrigeration unit.
A turnkey cold room project can include site assessment, engineering, refrigeration load calculation, panel selection, door selection, equipment selection, installation, testing and commissioning.
Businesses looking for turnkey cold room installation should ensure that all components are designed to work together.

Frequently Asked Questions
What is a double regime cooling unit?
It is a refrigeration system designed to operate at different temperature ranges according to the requirements of the project.
Can one cold room be used for both chilled and frozen products?
Depending on the system design and equipment specifications, the same physical room can be used for different products at different times. The system must be engineered for the required temperature range.
What is the difference between a cold room and a frozen storage room?
A chilled cold room generally operates at temperatures above freezing, while frozen storage requires substantially lower temperatures. The insulation and refrigeration equipment must be selected accordingly.
How is cold room price calculated?
Cold room pricing depends on dimensions, volume, panel, door, refrigeration equipment, temperature requirements, installation and other project-specific factors.
Are double regime systems suitable for every cold room?
No. Suitability depends on the required temperature range, product characteristics, refrigeration load, insulation, equipment and operating conditions.
