Using a rotating exhaust design, the lastest development of the fourth generation line, optimize the circumference speed, excellent design of gear so that the unit has higher compression efficiency. Motor chamber compression chamber integrally cast, high precision. Double pressure compensated rotor housing, very strong, no expansion even in the state of high pressure, and it effectively reduces the noise.
Heat exchanger
The condenser and evaporator of this series unit adopts shell and tube heat exchanger, using new high efficient heat exchanger structure. Heat exchanger adopts the most advanced and effcient heat exchanger tube bundle with unique geometric characteristics and enhanced tube nucleate boiling required vaporization core, strengthen the fluid in the tube and delay perturbationat the same time, the water side fouling, heat transfer enhanment, the inside wall in order to get the best performace, comparade to the previous design, the unique design of the heat transfer efficiency is increased by 30%.
Evaporator evapotation tube with inner grooved on outer concave tooth enhanced heat transfer technology, condenser tube with inner grooved cutter teeth technology, improves the evaporator and condenser heat transfer efficiency and the evaporation temperature, and improve the energy efficiency ratio for the unit.
PLC

FAQ
Q: How to choose air cooled system or water cooled system? Air cooled is better or water cooled is better?
A: In terms of installation simplicity, the air cooled system is more convenient than the water-cooled system and does not need to connect cooling towers. The water cooled system needs to be connected to the cooling tower then it can run. In terms of energy efficiency, the water cooled system has higher energy efficiency than the air cooled system. Specifically, according to your environment and situation, engineers will design an optimization plan for you.
Q: What is the outlet temperature of your chiller?
A: -55 to 15 centigrade.
Q: What’s payment terms?
A: 50% as deposit, 50% before delivery by T/T, Western Union and Paypal is our regular payment terms. D/P, L/C need to have a discussion.
Q: What is the warranty of water chiller?
A: The standard warranty is 12 months.
Q: What is the delivery time?
A: Usually around 30 days.
