FEATURES AND BENEFITS
3/62
- 3 noise versions: Standard, Low and Reduced each one carefully designed to meet the acoustic
requirements of the installation site.
Outstanding reliability.
The chillers have one or two truly independent refrigerant circuits with two or three compressors, to assure
maximum safety for any maintenance, whether planned or not.
Condensation control.
Single-V units are standardly equipped with continuous fan speed modulation (phase cut) to ensure precise
airflow control and optimized condensing temperature. Multi-V units are equipped with fan speed modulation
(VFD) on request (standard on reduced noise units).
Fan silent mode.
Units equipped with fan modulation are standardly supplied with fan silent mode. This feature allows the user
to set up detailed time bands to reduced fan rotation speed and therefore sound emission in those areas where
night quietness is a mandatory requirement (approximately -4dB(A) – detailed values are available on CSS
selection software)
Superior control logic.
The MicroTech III controller provides an easy to use control environment. The control logic is designed to provide
maximum efficiency, to continue operation in unusual operating conditions and to provide history of unit
operation. 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 single system.
Dynamic Condensing Pressure Management.
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.
Code requirements – Safety and observant of laws/directives
