Can R22 be directly replaced with R410a in an existing chiller system?

No. The physical and chemical parameters are different. R410a requires different components like high-strength copper pipes and POE oil. Direct replacement is not possible without system redesign.

What certifications does the chiller have?

The chiller is certified with RoHS, UR, ISO, CE, CCC, and Ahri/Craa/EMC/PTC standards.

What is the lead time for delivery?

The average lead time is one month for both peak and off-peak seasons.

Product Q&A

Q:How to install the air cooled chiller?

Choose a flat open space with a cement foundation. Connect pipes with matching diameters. Ensure normal water flow and positive pressure. Install vibration isolators on piping. Ensure good ventilation and treat poor water quality to avoid deposits.

Q:What is the difference between R22 and R410a refrigerant?

R410a is eco-friendly with zero ODP, while R22 destroys the ozone layer. R410a requires POE oil, has higher operating pressure (50-70% higher), and needs high-strength copper pipes. R410a cooling efficiency is 47% higher than R22.

Q:What are the main functions of water-cooled screw chillers?

Main functions include refrigeration, heating, heat recovery, and cold recovery. They are used in industrial fields like food processing and commercial places like hotels to maintain precise temperature ranges.

Q:What is the working principle of a screw chiller unit?

The compressor sucks low-pressure refrigerant, compresses it into high-pressure gas, and sends it to the condenser. The refrigerant condenses into liquid, expands through a valve, and absorbs heat in the evaporator to cool water, completing the cycle.

Q:What is the warranty period for the chiller?

The free warranty period for the whole machine is 1 year from the date of delivery. Lifetime maintenance is available, with paid services and preferential spare parts offered after the warranty period.
