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.
