HIGH EFFICIENCY
AIR-COOLED SCREW CHILLER
CLIMAVENETA "ERACS.C" high efficiency screw chiller has introduced the latest technology from Italy which can obviously reduce the total investment and operation cost without conventional cooling tower, cooling water pump and the cooling system. The unit can be installed on the building roof or outdoor that no need extra plant room. The ERACS.C units are optimized for all commercial and industry application.
High Efficiency Air Cooled Screw Chiller
High Performance Fan
High efficiency exterior rotor fan from German brand. It can reduce the energy consumption and fan noise.
Screw Type Compressor
- Semi-hermetic screw compressor specially designed for HFC134a with higher compression efficiency under full load as well as part load;
- Precisely manufactured twin-screw rotor with aircraft-grade bear featuring in high reliability, low noise, low vibration and stable running;
- The motor drive the bear directly with least moving component and wearing part that cause no energy loss and higher mechanical efficiency;
- Automatically adjust power output according to load by microprocessor;
- The slide valve is fixed for stepless control and increase part load performance.
Super Low Noise
All compressors of ERACS.C series are installed on the vibration isolator. The rubber pad is also fixed between compressor and frame to prevent vibration and noise. The fan is exclusive designed with aircraft grade blades and aluminum-cast exterior motor as well as the air deflector cylinder to eliminate air side noise. According to different noise request in different application, the super low noise unit also can be installed. The noise of super low noise unit (SL)is 8-10 dB(A) lower than standard unit (B).
Electronic Expansion Valve
EXV, with high-sensitivity and precise control, has high adaptability of partial load working condition. And it can improve the efficiency of the unit under full load as well as part load.
Reliable Operation
The unit is designed, manufactured, tested according to international and local standard AHRI, EN, UNI, JIS, GB/T18430.1 for reliable performance. And the electrical system is also strictly designed and produced comply with standard IEC60204-1/GB5226.1. The unit is controlled by the dedicated microprocessor control system. In order to protect the operation safety, the high/ low pressure switch, over/under voltage, phase failure, over load, winding over heat, gas exhaust temperature, water flow switch and oil heater are all equipped. For the evaporator, the heater is attached to the evaporator exterior to prevent freezing.
Heat Recovery-Hot Water Free!
The heat of condensation usually will be exhaust to the environment during air-cooled heat pump working in cooling. And also the unit can not transfer all the heat during heating. So CLIMAVENETA introduce the heat recovery technology which can recovery the condensation heat during cooling and extra heat during heating to produce free hot water. This technology will help users to save obvious operation cost.
Optional function:
low outdoor temp. working, ice storage, fin protection, anti-salt
protected fin, remote keyboard, power factor regulation and so on.
Note:
The anti-noise chamber for compressor is option for standard (-B)
unit. Please order if required.
Latest control system
The chiller adopts a new control system with a friendly human-machine interface, excellent controls and adjustments ability, strong capabilities of function expansion, monitoring and management, as well as strong compatibility. The chiller also contains several optional accessories, and adds remote and group control functions.
Heat Recovery-Hot Water Free!
The operation screen is embedded in the unit for easy operation and good protection. The automatic control by the computer realizes unattended operation. LCD screen can display data and parameter adjustment in various languages and menus. According to the tradition of Climaveneta, the status and parameters of the compressor are visually displayed individually to make sure the operating status clear at a glance.
Unit control and operation
management
The advanced microcomputer intelligent control system of W3000 contains specially designed control algorithm of Climaveneta. It highlights the energy efficiency and reliability of the unit. The balanced running time of FIFO compressor prolongs the life of machine. The automatic adjustment of the output load makes the machine more energy saving. Combining with the load shedding system of the compressor can achieve 25-100% stepless adjustment. The adjustments and settings of the operating parameters can adapt to different environments. The temperature and pressure protection using analog measurement can predict and prevent of failure and increase reliability.
Fault protection, alarm and analysis capabilities
The microcomputer intelligent controller contains perfect functions of fault protection, alarm, recording and analysis. It has protection functions of high/low pressure switch, lack of phase, reverse phase, overload, overcurrent, overheat, exhaust temperature, water flow, frost and so on. The controller also achieves fault recording and alarm display. The unique “Black Box” fault recording and analyzing system can record 400 failures and more than 200 field data before each failure. It can diagnose and remove faults rapidly to improve the technical support effect. By connecting to the Climaveneta remote service program, it can find potential failures before they occur and take proper preventive treatments.
FWS network server
Microcomputer intelligent controller can be equipped with FMS network server to monitor, set and adjust parameters and control the unit operation through LAN or Internet.
Network communication and building management control
The chiller supports BMS connection and can connect to common BMS systems such as Climaveneta, De’Longhi, MODBUS, LONWORKS, BACNET and so on.
