CWW/TTY 1601-1÷14406-1

A CLASS energy efficiency watercooled liquid chillers with TURBOCOR (magnetic levitation) compressors and flooded shell and tube exchangers for cooling tower operation

The innovative CWW/TTY 1601-1÷14406-1 TURBOLINE units for cooling tower operation, featuring A CLASS energy efficiency, are designed to provide an effective solution to highly selective system needs. Efficiency at partial loads, low breakaway starting current, low levels of operational noise, reduced weight and the specific design and handling every manufacturing aspect, make the series the top of the range.
Using TURBOCOR dynamic partial-load oil-free magnetic levitation compressors, managed by the TURBOSOFT self-adaptive electronic control and flooded shell and tube evaporators, provide high energy performance, with unbeatable SEER values, with minimum water content, and an excellent silent functioning. Compared to traditional Screw compressor units, units have low operational costs during their entire use, with a savings that can even reach 50%.
The units are compliant to the 2021 ErP Regulation.

On request, units can be supplied with R513A refrigerant.

Shell and tube type condenser, with easily removable cast iron heads to enable access for maintenance operations.
High efficiency flooded shell and tube type evaporator, with one circuit on the refrigerant side and one on the water side, complete with water differential pressure switch.
Cooling circuit shut-off valves on suction, discharge and liquid line.
Electronic expansion valve.
Electronic high and low pressure gauges.
R134a refrigerant. On request R513A refrigerant.
Electrical board includes: main on-off switch with door lock, fuses, electronic/digital overload device to protect the compressors, interface relay and terminals for external connections.
TURBOSOFT control and regulation system, equipped with RS485 serial interface, can be supplied with an optional Web Monitoring device for remote monitoring via GPRS/EDGE/3G/TCP-IP network.
