Carrier 30GX PRO- User Manual

30GX 50 Hz

Nominal cooling capacity 282-1203 kW

The 30GX units are air-cooled chillers, designed from the
ground up to meet the needs of today and tomorrow:
- ecological HFC-134a refrigerant
- screw compressors
- compact footprint
- mechanically cleanable evaporator
All units are equipped with PRO-DIALOG Plus control to
optmize the efficiency of the refrigerant circuit, and with
the revolutionary FLYING BIRD fan with rotating shroud.
This innovative fan considerably reduces the air circulation
noise and contributes to quiet unit operation. It is made of
fully recyclable composite materials.

Features

Quality design and construction make the 30GX unit the
preferred choice.

■

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

■

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

■

The 30GX units are equipped with screw compressors and
with shrouded axial Flying Bird fans for extremely quiet
operation and low-vibration levels.

■

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

■

The 30GX 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.

■

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

■

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

■

Auto-diagnostics - quick display of the machine status.

■

Multiple compressor concept for optimized part-load effi-
ciency and minimized starting current.

■

Series star/delta starter, limiting the start-up current on
30GX 082-182 units.

Easy installation

■

The 30GX has a compact design that is up to 50% smaller
than current chillers. The 30GX is supplied as a complete
package for easy installation. There are no extra controls,
timers, starters or other items to install.

■

30GX units have a single power point and one main discon-
nect/isolator switch for sizes 30GX 082 to 182, and one
power point and one main disconnect/isolator switch per
circuit for sizes 30GX 207 to 358.
The hydraulic connections are simple and facilitated by the
use of Victaulic connections for the evaporator.
