Physical Data and Weights
Evaporator
The optional insulation of cold surfaces includes the evaporator and non-connection water head,
suction piping, compressor inlet, motor housing, and motor coolant suction line.
The insulation used is UL recognized (File # E55475). It is 3/4" thick ABS/PVC flexible foam
with skin having a K factor of 0.28 at 75°F. The sheet insulation is fitted and cemented in place
forming a vapor barrier, then painted with a resilient epoxy finish that resists cracking.
The insulation complies to appropriate requirements or has been tested in accordance with the
following:
ASTM-C-177 ASTM-C-534 Type 2 UL 94-5V
ASTM-D-1056-91-2C1 ASTM E 84 MEA 186-86-M Vol. N
CAN/ULC S102-M88
Refrigerant side design pressure is 200 psi (1380 kPa) on WSC units. WDC evaporators are 180
psi (1242 kPa) and WDC condensers are 225 psi (1552 kPa). Standard water-side design pressure
is 150 psi (1034 kPa) on all vessels. 300 psi (2068 kPa) is available as an option.
In the event insulation is to be field installed, the approximate total square footage of insulation
surface required for individual packaged chillers is tabulated by evaporator code and can be found
below.

Notes:
1. Water capacity is based on standard tube configuration and standard heads.
2. Vessel weight includes the shell, maximum tubes, and standard heads, no refrigerant.
3. MWB, marine water box, weight add is the water box weight minus a standard dished head weight.
