Recently our R&D team is working days and nights in the lab to test our electric A/C + electric defroster system.

This combination is one of our key breakthrough: no one except CLING in China has conquered the task of "smooth compressor oil return", "0 loss in A/C performance during defroster operation". This ECSQ defroster is applied on high end bus and coach, providing defrosting, defogging, cooling, heating functions, very well improves driver's satisfaction .

Our customer used to purchase from other supplier, but now they choose us simply because only our team cracks this difficulty.

CLING invests a lot on R&D, having China National first class lab, and is one of the setters of China bus & coach HVAC system standard.
