FWCD- 030 31.5
FWCD- 045 42.7
FWCD- 055 52.4
FWCD- 065 65.6
FWCD- 075 75.1 2
FWCD- 085 84.8 2
*Note: The nominal capacities reflect the use of R-410A refrigerant and a standard heat exchanger.
Digit 8 — Unit Voltage
All units have single point power blocks with grounding lugs and 12V control circuits.
A = 208 V/60 Hz/3 Phase
B = 230 V/60 Hz/3 Phase
F = 460 V/60 Hz/3 Phase
G = 575 V/60 Hz/3 Phase
Digit 9 — Unit Application
A = Water-Cooled Chiller – Standard water-cooled chiller with optional shell and tube condenser
or brazed plate condenser and brazed plate evaporator.
B = Compressor Chiller with Remote Condenser – FWCD chillers can be configured without a
condenser and mated with an air-cooled condenser.
Digit 10 — Refrigerant Style
A = R-410A Scroll
Digit 11 — Number of Circuits
1 = Single Circuit – Two compressors per module are piped on a single, tandem circuit to single
circuit evaporators and condenser.
2 = Dual Circuit – Two compressors per module are piped independently to dual circuit evaporator
and condenser.
