™ air cooled

scroll liquid chillers provide chilled liquid

for all air conditioning applications. They

are completely self-contained and are

designed to be located outside on the roof

of a building or at ground level.

Each unit includes four, five or six hermetic

scroll compressors, a liquid cooler, air

cooled condensers, and a weather

resistant microprocessor control centre,

all mounted on a formed steel base.

FEATURES BENEFITS

High efficiency. Low operating costs.

Electronic Expansion Valves (EEV) fitted as

standard.

Enhanced efficiency and improved part load performance.

Manufactured to ISO 9001/EN 29001. High standard of quality control.

Full factory run test. Verifies quality control and ensures that the unit operates

satisfactorily prior to delivery.

Optional acoustic kits. Reduced sound levels for low sound applications.

Small footprint. High capacity design ideal for reduced base area

applications.

Two refrigerant circuits. System stand-by security.

Accessible components. Ideal for maintenance operations

Microprocessor control with visual display of

temperatures and alarms.

Simple operation.

Optional multi-unit sequencer. Sequencing up to eight chillers in parallel based on mixed

leaving liquid temperature.

Chiller remote alarm contacts. Remote alarm notification.

Single power and control supply. Easy to install and minimises site wiring costs.

Optional remote liquid temperature reset. Improved operating efficiency at part load and reduced

operating costs.

SPECIFICATION

The chillers shall be completely factory assembled with all interconnecting

refrigerant piping and wiring ready for field installation. After assembly the unit shall

have a full test run with water flowing through the cooler. The unit shall be pressure

tested, evacuated and fully charged with refrigerant and include an initial oil charge.

The unit structure is heavy-gauge, galvanised steel coated with baked-on powder

paint (Desert Sand (RAL 1019)).

Compressors

The unit shall have hermetic scroll compressors. High efficiency is achieved through

a controlled orbit and the use of an advanced scroll geometry. All rotating parts are

statically and dynamically balanced. The compressor motors shall have integral

protection against overloads. The overload protection will automatically reset.

Starting shall be direct on line. The motor terminal boxes shall have IP-54 weather

protection.

The compressors shall be switched On and Off by the unit microprocessor to

provide capacity control. Each compressor is fitted with a crankcase strap heater.
