Frequently Asked Questions (FAQ)
What testing standards do these products undergo to guarantee air tightness?
All units undergo a rigorous 2.6MPa air tightness test to strictly comply with industrial safety and leak-proof standards.
How does the design reduce operational noise and vibration?
The panel and side plates are engineered with a stepped structural design, which effectively dampens fan operating noise and minimizes system vibration.
What measures are taken to prevent corrosion on the casing?
The outer equipment shell undergoes a professional phosphating treatment followed by surface spraying processes to ensure superior corrosion resistance and a smooth, long-lasting finish.
Can the defrosting system be automated?
Yes. While the system comes standard with high-insulation stainless steel heating tubes, users can additionally install a controller module to enable automatic defrosting control for optimized efficiency.
What are the temperature parameters for the DJ, DD, and DL cooling capacities?
DJ capacity is based on -25℃ inlet / -31℃ evaporation; DD is based on -18℃ inlet / -25℃ evaporation; DL is based on 0℃ inlet / -8℃ evaporation.
What types of cold storage applications is this equipment suitable for?
This equipment is ideal for fruit and vegetable preservation, special medical storage, flower preservation, red wine storage, aquatic product processing, special testing, and food processing cold storage.
