FEATURES AND BENEFITS
2/100
Low operating cost Flexibility and Reliability The EWAH-TZ 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,
effectiveness and economical management. The chillers feature high efficiency single screw Inverter driven
compressor design, optimized condensing section, advanced technology condenser fans and a “shell & tube” or
plate heat exchanger evaporator with low refrigerant pressure drops.
The EWAH-TZ B range came with 3 efficiency level
-
EWAH~TZ B S- “SILVER”: avg. EER 2,9 avg. ESEER 4,7
-
EWAH~TZ B X- “GOLD”: avg. EER 3,4 avg. ESEER 5,1
-
EWAH~TZ B P- “PLATINUM”: avg. EER 3,7 avg. ESEER 5,3
and 3 sound levels:
- Standard sound
- Low sound: the sound attenuation is achieved thanks to special connections at the suction of each compressor
that allows to reduce drastically the vibration transmission.
-
Reduced sound: the compressors are closed into a soundproof cabinet especially designed to minimize the
sound emissions. Also special connections at the suction of each compressor allows to reduce drastically the
vibration transmission.
An extensive list among of mechanical, electrical, control and installation related options are available
Combining all together, more than 500 combinations are available.
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 one or 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 gaterotors 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 an Inverter driven screw
compressor controlled by microprocessor system. Each unit has infinitely variable capacity control from 100%
down to minimum capacity which is variable depending on unit model. This modulation allows the compressor
capacity to exactly match the building cooling load without any leaving evaporator water temperature fluctuation.
This chilled water temperature fluctuation is avoided only with a stepless control.
Inverter stepless regulation plus variable volume ratio control Based on the geographical location and
the application, the outside temperature and the load profile of a building can vary enormously but our system
has an infinitely variable load regulation and working conditions without pre-set steps for a perfect comfort
solution. The inverter stepless regulation plus variable volume ratio control provides the required capacity to
meet the demand, ensuring highly accurate leaving water temperature control and so delivering optimal comfort
with the best performances possible at every condition.
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.
Dynamic Condensing Pressure Management A new superior software logic has been developed to get the
highest efficiency at whichever operating condition: thanks to the Dynamic Condensing Pressure Management
the chiller controller adjusts the condensing pressure set-point to minimize the overall chiller power input.
