Extended Functions：
—B Standard uint -SL Super low noise unit -FC-NG No glycol FreeCooling unit -FC Standard FreeCooling unit
Frame Structure Description：
Base and frame in thick hot-galvanised shaped sheet steel. All parts polyesters-painted.
Compressor Description：
1, The unit adopts efficient flexible scroll compressor, high energy efficiency ratio, quiet operation; Flexible compressor structure, liquid impact resistance, wear resistance, high reliability.
2, Double compressor design, can adjust the number of compressor operation according to the load change, small starting current.
Evaporator Description：
The AISI316 stainless steel brazed plate heat exchanger is used for high efficiency heat exchange. The surface is covered with closed cell neoprene insulation material to prevent condensation on the surface of plate heat exchanger. And built-in plate electric heater to prevent plate heat exchanger from being damaged by freezing under bad conditions.
Condenser：
Climaveneta design of special cooling coil, the refrigerant coil and natural cooling coil organic combination, can maximize space savings, both compressor refrigeration or all natural cooling can meet the demand for cooling capacity.
Control Cabinet：
The optimal natural cooling pipeline program intelligent control is an effective way to save energy, Climaveneta air source natural cooling unit adopts advanced W3000 microcomputer intelligent control system, when the ambient temperature is lower than the return water temperature 2℃, the unit opens part of the natural cooling, Its unique adaptive function can intelligently adjust the compressor cooling amount according to the change of user water temperature and outdoor environment temperature, minimize the compressor work and maximize natural cooling on the premise of meeting the total cooling demand, and ensure the unit to run in the most energy saving way.
Control System：
● New generation regulation system with human-computer interface, better extended utility, supervision and compatibility.
● Panel screen on the unit, easy operation, better protection Microprocessor regulation fulfill human-free running.
● W3000 with LCD display, multi-language & multilevel menu for data display & set-point regulation .According to CLIMAVENETA tradition, another display of compressor’ working data is adopted for easy supervision.
● Dedicated W3000 microprocessor is inserted with CLIMAVENETA control algorithm to make sure energy saving and reliability.
● FIFO compressor running time balance function extends unit’ working life;
● Auto compressor power input control following with load change from 25-100% for energy saving;
● Environment adaptation by data regulation and setting;
● Modulating measurement is used for temperature pressure protection. It can increase reliability and predict fault occurs. ● Expansion kit for remote control and group control.
● Available in BMS control, such as ModBus, LonWorks, BacNet control system.
● Microprocessor have complete fault predict, alarm, record and self diagnose function assuring operation protection & working state.
● “Black Box” record 400 faults and 200 data before each fault, which diagnose & remove fault quickly
● We also can find potential fault and take preventive action before it occur by CLIMAVENETA remote service program
Total natural cooling at high ambient temperatures：
According to the climaveneta characteristics of most cities in northern China, the ambient temperature is relatively low most of the time. Climaveneta’s latest natural cooling technology enables the unit to enter the full natural cooling state when the ambient temperature is lower than 2℃. When the ambient temperature rises, the unit will automatically adjust, without affecting the cooling capacity of the whole machine.
