Heat exchange for additional super-cooling of the liquid refrigerant closed refrigeration chamber contains evaporator with fan and adjustable electric heater as cooling load
Digital display for temperatures, drive power of the compressors and cooling load power
Power consumption: about 550W
Refrigeration capacity: 1700W at -10C'
230V, 60Hz, 1 phase
Unit complete with all required accessories.

Innovative Two-Stage Compression Technology

By utilizing a hermetically sealed dual-stage compressor, this system achieves higher efficiency and superior cooling across its temperature range. Two-stage compression reduces the workload per stage, improving reliability and lowering operation costs.

Eco-Friendly Refrigerants and Safety Assurance

The use of CFC/HCFC-free refrigerants (R134a, R404a) minimizes environmental impact while integrated overload protection and low-pressure cut-out enhance operational safety.

Comprehensive Data Acquisition and Digital Monitoring

A built-in USB port allows users to log critical data for analysis, while the digital display provides real-time readings of temperature and pressure, supporting advanced research and educational needs.

FAQs of Refrigeration System With Two-Stage Compression:

Q: How does the two-stage compression enhance the refrigeration systems performance?

A: The two-stage compression process divides the task of compressing refrigerant into two phases, which improves efficiency, results in lower energy consumption, and allows the system to achieve and maintain very low temperatures with better stability.

Q: What type of compressor is used in this system and why?

A: This system utilizes a hermetically sealed dual-stage compressor. Its sealed design prevents refrigerant leaks and extends the compressors service life, while the dual-stage mechanism ensures efficient cooling over a wide temperature range.

Q: When should the built-in USB data logging feature be used?

A: The USB data logging function is especially beneficial during experimental setups, training sessions, or long-term monitoring when detailed analysis of operational parameters like temperature and pressure is required.

Q: Where is this refrigeration system typically used?

A: Common applications include vocational training institutes, R&D laboratories, and industrial demonstration environments where hands-on learning or precise cooling control is essential.

Q: What safety features are integrated into the unit?

A: Overload protection and a low pressure cut-out are built in to prevent damage to the compressor and other components, ensuring safe operation even under demanding laboratory or demonstration conditions.

Q: How do users benefit from the transparent observation panel and digital display?

A: The transparent panel allows direct visualization of the refrigeration process, which assists in teaching and troubleshooting, while the digital display offers clear, accurate monitoring of system temperature and pressure for enhanced control.

Q: What is the process for adjusting the temperature range?

A: Temperature adjustment is managed via the integrated control panel, which provides digital setting and monitoring. Users can set desired values within the -40C to +10C range and view real-time changes on the display.
