Strong backup functions
When unit is failed: If one slave unit fails, failed unit will stop but the others will keep running.
If master unit fails, all the units will stop but any of the slave one can be set as the master unit by manual setting in a very short time. When unit is under protection: If master unit’s protection happens, protected unit will stop but the others will keep running.
If slave unit’s protection happens, protected unit will stop but the others will keep running .
Except PE, P9 protection happens.(PE:Low temperature protection of evaporator.
P9:Outlet and inlet water temperature difference protection.)
Max.16 can be combined in one system,up to 2000kW after combined.
The modular design facilitates easy expansion in phases to respond to additional cooling requirements,this solution provides excellent partial load facility, low initial investment cost.
Wide range of outlet water temperature
Cooling: 5~17°C (7°C is default,set in factory), 0~17°C can be available by switch the S5 on PCB, the antifreeze must be put into pipeline.
Heating: 40~50°C (45°C is default, set in factory), 22~50°C can be available by switch the S4 on PCB.
High/low pressure protection of compressor.Power phases protection.Evaporator low temperatureprotection in cooling.System anti-freezing protection in winter.Frequently ON/OFF protection of compressor.Over-current protection
of compresor.Air discharge temperature protection of compressor.System high temperature protection.Water flow protection.Sensor malfunction protection.
