TS Series
Design and Component Specifications
20 to 100 Tons
TSR40A With Pump/Reservoir Option
General
The TS Series central chillers are designed for indoor
use in industrial manufacturing locations. The chillers
are produced in our ISO 9001:2000 certified facility.
Water-cooled units ship with a full refrigerant charge.
Units with a remote air-cooled condenser ship with a
nitrogen charge. All units are built on a rugged
industrial duty frame and are finished with air-dry
enamel paint.
Mechanical Features
• Energy efficient and reliable scroll compressor(s)
• Stainless steel copper brazed plate evaporators
provide corrosion protection, compact size and
higher heat transfer coefficients
• Two completely independent refrigerant circuits
• Evaporator water supply and return manifolds
• (Water-Cooled Units) Condenser water supply and
return manifolds
• (Water-Cooled Units) Generously sized cleanable
shell-and-tube water-cooled condenser for industrial
environments
• (Remote Condenser Units) Modular design with
divided fan sections to prevent ‘wind-milling’ during
fan cycling. Includes galvanized steel fan sections
and coil baffles, copper tube/aluminum fin coils
tested to 400 PSIG, direct drive multi-blade propeller
fans with venture orifices to optimize efficiency, and
a nitrogen holding charge.
• (Water-Cooled Units) Condenser water regulating
valves to maintain constant refrigerant head
pressures
• Refrigerant TXV, filter/drier, and sight glasses
• Freezestat safety switch with solid state sensors
• Encapsulated high and low refrigerant pressure
safeties
• Fail safe flow switches interlocked with compressors
• Y-strainer for each evaporator to protect evaporators
from contamination
• Electronic hot gas bypass for capacity control (two
compressor units)
• Four-step compressor staging for capacity control
(four compressor units)
• (Water-Cooled Units) Factory tested under full load
conditions prior to shipment
Electrical Features
• NEMA-4 electrical enclosure
• Control transformer to provide 115V/1/60 control
voltage
• Compressor starters (and pump starters if pump
tank option is purchased) mounted in control panel
and wired to motors
• Single-point main power block for simple wiring
connection
• Alarm horn and silence switch
PLC Features
• Operator Control Station PLC (integrated Intel based
microprocessor controller, operator interface, solid
state input/output relays)
• Two line, 20 character alphanumeric display
• Digital set point and temperature deviation alarm
adjustment with password protection
• Digital display of process water supply and return
temperatures
• Alarm history screen
• User selectable lead/lag of refrigerant circuits
• Compressor anti-cycle timers
• Compressor running hours
• Mechanical safety interlocks for each circuit
including low flow, high refrigerant pressure, low
refrigerant pressure, freezestat, compressor fault
and pump fault (pump fault only available on units
with the optional pump tank)
• System faults for high and low temperature deviation
alarms and probe fault alarm
• Display temperatures easily switched from °F to °C
from the front panel
• Easy front panel alarm reset button
Warranty
• 12 months parts and labor

1Cooling capacity based on 12,000 BTU/Hr/ton with 55°F leaving coolant and 85°F condenser water.
2MCA (Minimum Circuit Ampacity) is 125% of the largest compressor RLA plus 100% of any remaining compressor RLAs (and all pump
FLAs if pump tank option is purchased) plus control circuit transformer. If a dual standby pump is order MCA will be higher.
3Shipping weight includes weight of double flow pump set and dual standby pump options.
