Frequently Asked Questions

Q: Why use two-stage compression instead of single-stage?
A: At -40°C evaporating temperature, single-stage compression would result in excessively high discharge temperatures and poor efficiency. Two-stage compression with inter-stage cooling reduces discharge temperature and improves COP significantly at ultra-low temperatures.
Q: What refrigerants can be used?
A: The dual-stage unit is optimized for R404a and R507 which are the industry standards for low and ultra-low temperature applications. These refrigerants provide the best capacity and efficiency at the target temperature range.
Q: Does this unit require special installation?
A: Standard refrigeration installation practices apply, but attention to proper oil return piping is critical for two-stage systems. We provide detailed installation guidelines and our technical team is available for support.
Q: What is the power consumption at -40°C?
A: Power consumption varies with operating conditions. At -35°C evaporating / +35°C ambient, approximate power input is 3.2kW. We can provide detailed performance data for your specific conditions.
Q: Can this unit be used as a drop-in replacement for single-stage units?
A: The two-stage system has different piping and control requirements compared to single-stage. We recommend consulting our technical team to evaluate your existing system compatibility.
