2.15 Options and Accessories
Model 'B' Solid State Starter
The liquid cooled solid state starter is a reduced voltage
soft starter that controls and maintains a constant
current flow to the motor during start-up. It is compact
and mounted on the unit adjacent to the motor terminals.
Power and control wiring is factory supplied. The starter
enclosure is IP33 rated with a hinged access door with
lock and key.
Standard features include: digital readout at the control
panel of 3-phase voltage and current; high and low line
voltage protection; 115 V control transformer; three-leg
sensing overloads; phase rotation and single-phase
failure protection; and momentary power interruption
protection. An integral door interlocked fused
disconnect switch is supplied as standard.
Factory Insulation
19 mm or 38 mm flexible closed-cell plastic type
anti-sweat insulation on the evaporator and liquid
refrigerant piping.
Factory Water Flanges
Welded to water nozzles on evaporator and condenser
(companion flanges and connecting parts not included).
Flow Switches
Paddle-type, vapour-proof water flow switches (10 or 20
bar DWP) for chilled and cooling water circuits.
Pressure Safety Devices
Pressure relief valves etc.for evaporator and condenser.
Dual Oil Filter
Housing with isolation valves to eliminate downtime
during filter changes.
Refrigerant Isolation Valves
Factory installed valves in compressor discharge line
and refrigerant liquid line to enable refrigerant
isolation/storage in unit condenser during servicing.
Hot Gas By-pass System
A hot gas bypass system can be factory installed to
allow unit operation down to virtually zero load if
required.
Sequence Control Kits
Sequence control kits for two, three or four units with
series or parallel chilled water arrangement.Kits provide
control and switching based on return water
temperature and enable centralised start/stop.
Spring Isolators
25mm deflection level-adjusting/spring-type vibration
isolator assemblies.
Form 3 Shipment - Motor/Compressor Separate
from Shells
Shipped as three major assemblies: Compressor/motor
assembly removed from shells and skidded.
Evaporator/condenser is not skidded. Oil separator is
skidded. All wiring integral with compressor is left on it,
and all conduit is left on shells. All openings on
compressor, oil separator, and shell are closed and
charged with dry nitrogen (0.5 barg). Miscellaneous
packaging of control panel, tubing, water temperature
controls, wiring, oil isolators, solid state starter (option),
etc; R134a charge not included.
Form 7 Shipment - Split Shells
Shipped as four major assemblies: Compressor/motor
assembly removed from shells and skidded. Oil
separator is skidded. Evaporator and condenser shells
are separated at tube sheets and are not skidded.
Refrigerant lines between shells are flanged and
capped, requiring no welding. Tube sheets will require
welding in field. All wiring integral with compressor is left
on it. All wiring harnesses on shells are removed. All
openings on compressor, oil separator and shells are
closed and charged with dry nitrogen (0.5 barg).
Miscellaneous packaging of control panel, tubing, water
temperature controls, wiring, oil isolators, solid state
starter (option), etc; R134A charge not included.
