China cold storage solution provider
HAOCOOL recently started the construction of a high–low temperature variable cold storage designed for laboratory and environmental simulation applications. This specialized cold storage supports temperatures from +50°C down to -40°C, covering a 90°C temperature difference, and is widely used for product testing, material aging, and controlled environment experiments.
Unlike standard cold storage rooms, a variable temperature cold storage is designed to frequently switch between different temperature zones, allowing one system to serve multiple testing or storage requirements.

What Is a Variable Temperature Cold Storage?
A variable temperature cold storage is a customized refrigeration system that allows both heating and cooling within the same insulated room, enabling precise temperature control across a wide range.
Depending on project size and usage scenarios, variable temperature cold storage systems are typically designed as:
- One unit, one chamber – smaller scale, dedicated testing or storage
- One unit, multiple chambers – larger scale, multiple temperature zones
The wider the temperature range, the higher the system complexity and investment cost.
How Much Product Can a Variable Temperature Cold Storage Hold?
Most variable temperature cold storage projects are small to medium in size, as they are used for testing or high-value products rather than bulk storage.
Typical capacity ranges:
- 10–30 cubic meters for laboratory simulation
- 30–100 cubic meters for pilot production or R&D centers
- Custom designs available for larger volumes
The storage capacity is determined by:
- Required temperature range
- Cooling and heating speed
- Product sensitivity to temperature change
Rather than maximizing volume, these projects focus on temperature accuracy, stability, and response speed.
Key Configuration and Technical Requirements
Because of the extreme temperature difference, variable temperature cold storage has much higher configuration requirements than conventional cold rooms.
Common design features include:
- 200 mm polyurethane insulation panels to reduce heat loss
- Ceiling-mounted evaporators with high airflow efficiency
- Integrated heating system for rapid temperature rise
- Ultra-low temperature refrigeration units
- Customized sliding doors suitable for extreme temperatures
- Intelligent temperature control system for precise adjustment
Faster heating and cooling speeds will significantly increase equipment cost, but are often essential for laboratory and testing environments.
How Much Does a High–Low Temperature Variable Cold Storage Cost?
The investment cost varies widely depending on temperature range, capacity, and performance requirements.
As a general reference:
- Small laboratory variable cold storage
Investment starts from USD 30,000 – 45,000 - Medium-sized multi-temperature chambers
Typically USD 60,000 – 130,000 - Extreme temperature range systems (+100°C to -80°C)
Fully customized solutions with higher budgets
Compared with standard cold storage, a variable temperature cold storage is not priced by square meter, but by temperature range, control accuracy, and system response speed.
Is Variable Temperature Cold Storage Worth the Investment?
For laboratories, R&D centers, and manufacturers of high-value or sensitive products, this type of cold storage provides:
- One system for multiple temperature scenarios
- Reduced need for multiple testing chambers
- Higher testing efficiency and data accuracy
- Long-term cost savings in product development and quality control
While the upfront investment is higher, the return comes from versatility, precision, and operational efficiency.
