Air-Cooled

Flotronic™
Liquid Chiller

Nominal 60-Ton Capacity

30GB060

Features

• Unit nominal capacity serves virtually any large com­

mercial or institutional air conditioning need or industrial

process cooling requirement.

• High-tech solid-state electronic control circuitry tested

to U.S. Government Space Agency standards.

• Microprocessor control maintains total control over

chiller functions, permitting intelligent control of the

refrigerant cycle.

• Diagnostic module with digital display included to

permit rapid troubleshooting just by pressing a button.

• Electronic expansion valves (EXV) operate down to

ISpsig (103 kPa) pressure differential. (Ordinary ther­

mostatic expansion valve typically requires lOOpsig

[690 kPa] differential.) This reduces compressor motor

power requirements and improves the unit EER.

• Flotronic™ chiller provides up to 28% efficiency im­

provement over standard 30GB chillers on an annual

basis.

• Additional operating cost savings with precise multiple-

step compressor capacity control.

• Multiple compressors and dual refrigerant circuits help

to protect against the possibility of loss of total capacity.

• Semi-hermetic 06E compressors are serviceable in

the field.

Designed for outdoor installation to minimize required

mechanical room space.

Air-cooled condenser design saves condenser water

and eliminates cooling tower.

Domestic units will operate to 115 F (46 C).

Protection against freeze-up — low water temperature

cutoff and electric heaters protect cooler.

Available as standard with aluminum fins and copper

tubes for normal applications, or with all-copper coils.

Field-installed accessories

• Demand limit control module (required for remote

ON/OFF control)

• Leaving chilled water temperature reset accessory board

• Sensor kit assembly for outdoor or space temperature

reset of chilled water temperature

• Ground current refrigeration circuit protection

• Discharge and suction pressure gage panel

• Oil pressure switch package includes oil pressure

switches (2) for unit

• Capacity control: accessory electric suction cutoff

unloader

• Motormaster® head pressure control (requires unit

modification for low-ambient operation)

Factory-Installed option (FlOP)

Thermal expansion valves — For those situations where

energy savings of the EXV are secondary and equipment

first costs are most important. With this option, the

electronic expansion valve and controls related to the

EXV function, head pressure control and its related

part-load energy savings, are deleted from unit and are

replaced by thermal expansion valves and liquid line

solenoid valves. Minimum operating ambient for FlOP

TXV-equipped units with standard head pressure control

is 32 F. Contact your Carrier representative for details

on operation at temperatures below 32 F. The FlOP model

continues to have microprocessor features and diagnostic

capability. Standard accessories are useable.
