IM 1044-2 Centrifugal Chillers 15
Physical Data and Weights
Evaporator
The standard insulation of cold surfaces includes the evaporator and non-connection water head, suction piping,
compressor inlet, motor housing, and motor coolant outlet line.
Insulation is UL recognized (File # E55475). It is 3/4" thick ABS/PVC flexible foam with a skin. The K factor is
0.28 at 75°F. 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, 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/WCC/HSC units and 180 psi (1242 kPa) on WDC
units. Water-side is 150 psi (1034 kPa) on all.
In the event insulation is to be field-installed, none of the cold surfaces identified above will be factory insulated.
Required field insulation is shown beginning on page 13. 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 and may vary depending on tube counts.
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.
