30HXC Screw Water Cooled Chiller

The 30HXC units are water-cooled chillers, designed from the ground up to meet the needs of today and tomorrow:

- Ecological HFC-134a refrigerant

- Screw compressors

- Fits through a standard door with no disassembly required.

- Mechanically cleanable evaporators and condensers

All units are equipped with PRO-DIALOG Plus control to optimize the efficiency of the refrigerant circuit.

Features

l   Quality design and construction make the 30HXC unit the preferred choice.

l   Non-controlled, ozone-benign HFC-134a refrigerant. HCF-134a is a proven, non-toxic, non-flammable refrigerant which will have the highest usage of any new refrigerant.

l   Medium-pressure refrigerant HFC-134a minimizes stress on the compressors and ensures their long operating life.

l   The 30HXC units are equipped with screw compressors for extremely quiet operation and low-vibration levels.

l   The 30HXC units exceed the efficiency level of average industry standards for both full- and part-load operation, saving on operating costs, through lower electrical costs.

l   The 30HXC control is fully automatic. The leaving water temperature is continuously monitored to detect load and flow changes. This combination provides the most precise temperature control available.

l   Two independent refrigerant circuits - the second one takes over automatically, when the first one malfunctions, maintaining partial cooling under all circumstances.

l   Easy installation - the 30HXC chillers are supplied with a full refrigerant charge, and conveniently located power supply and water inlet and outlet connections.

l   Auto-diagnostics - quick display of the machine status.

l   Multiple compressor concept for optimized part-load efficiency and minimized starting current.

l   Series star/delta starter, limiting the start-up current on 30HXC 080-190 units.

l   30HXC 080-375 units are also available as high condensing temperature and non-reversible heat pump versions (options 150 and 150A). Their application range is the same as for the standard units, on which they are based, but they also allow condenser leaving water temperatures of up to 63°C. PRO-DIALOG control offers all the advantages of the standard units, plus control of the leaving condenser water temperature.

Easy installation

l   The 30HXC has a compact design that fits through a standard door opening and requires minimal indoor space. The 30HXC is supplied as a complete package for easy installation. There are no extra controls, timers, starters or other items to install.

l   30HXC units have a single power point and one main disconnect/ isolator switch for sizes 30HXC 080 to 190, and one power point and one main disconnect/isolator switch per circuit for sizes 30HXC 200 to 375.

The hydraulic connections are simple and facilitated by the use of Victaulic connections for the evaporator and condenser.

Simple to service

l   Mechanically-cleanable evaporator and condenser

l   Twin-screw compressors which require minimum routine service or maintenance.

l   Easily accessed suction and discharge pressure and temperature information via a display module.
