Frequently Asked Questions
Q: Can I switch refrigerants after installation?
A: The unit is factory-configured for specific refrigerants. While the compressor can handle multiple refrigerants, the expansion valve and other components should be matched. Contact our technical team before changing refrigerants.
Q: What is the advantage of multi-refrigerant compatibility?
A: It provides operational flexibility, reduces spare parts inventory, and allows the same unit model to be deployed across different sites with different refrigerant requirements.
Q: Is R134a suitable for low temperature applications?
A: R134a is best suited for medium/high temperature applications. For low temperature freezer applications, we recommend R404a or R507 for optimal performance.
Q: How is the oil management handled across different refrigerants?
A: The unit uses B5.2 refrigeration oil which is compatible with all supported refrigerants. The semi hermetic design includes an efficient oil pump and separator system.
Q: What is your delivery time for this model?
A: Standard delivery is 15 working days. Custom configurations may require additional lead time. Contact us for current availability.
