- Adopt R407C, R410a, R134a, R22 as refrigerant, according to the requirements of EU Montreal Protocol.
- The condenser uses titanium metal, its corrosion resistance is 4-5 times of ordinary copper tube, the corrosion ability of the unit is significantly improved, while the effective way to prevent fluoride leakage. So the medium of heat exchange can also contain seawater, mild industrial water, etc.
- By means of both mechanical and automatic control. Defrosting can be operated in a shorter time to avoid severe attenuation of heating capacity in winter and not run when not necessary.
Various protective measures
- Lack-phase and anti-phase protection
- Self memory function when power off
- Overpressure protection
- Leakage refrigerant protection
- Water protection for unit
- Overcurrent protection
- Temperature over protection
advanced control system
- Displaying operating and trouble status.
- Checking real-time operation parameters etc.
- The cable length between controller and the unit can be up to 100m for flexible installation.
- Keep balance running of compressor
- YUELLY products and the world famous brand compressor manufacturers
- (COPELAND\MISUBISHI\DAIKIN\PANASONIC\SANYO\GMCC) have good cooperation, so as to ensure the high quality of the machine.
