FEATURES AND BENEFITS

2/73

Low operating cost and extended operating life. EWAD~T -B chiller range is the result of careful

design, aimed to optimize the energy efficiency of the chillers, with the objective of bringing down

operating costs and improving installation profitability, effectiveness and economical management.

The chillers feature a high efficiency single screw compressor design, large condenser coil surface area

for maximum heat transfer and low discharge pressure, advanced technology condenser fans and a

‘shell&tube’ evaporator with low refrigerant pressure drops.

Low operating sound levels Very low sound levels both at full load and part load conditions are

achieved by the latest compressor design and by a unique new fan that moves large volume of air at

exceptionally low sound levels and by the virtually vibration -free operation.

Outstanding reliability The chillers have two truly independent refrigerant circuits, in order to assure

maximum safety for any maintenance, whether planned or not. They are equipped with a rugged

compressor design with advanced composite compressor gate rotors material, a proactive control logic

and are full factory - run-tested to optimized trouble -free operation.

Infinite capacity control Cooling capacity control is infinitely variable by means of a single screw

asymmetric compressor controlled by microprocessor system. Each unit has infinitely variable capacity

control from 100% down to 12,5%. This modulation allows the compressor capacity to exactly match

the building cooling load without any leaving evaporator water temperature fluctuation:

Superior control logic The MicroTech III controller provides an easy to use control environmental. The

control logic is designed to provide maximum efficiency, to continue operation in unusual operating

conditions and to provide a history of unit operation. One of the greatest benefits is the easy interface

with LonWorks, Bacnet, Ethernet TCP/IP or Modbus communications. Master/Slave operation is

provided as standard allowing to connect up to 4 units working as a single bigger chiller.
