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 DWSC/DWCC/DHSC units and 180
psi (1242 kPa) on DDWDC 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 19. Approximate total
square footage of insulation surface required for individual packaged chillers is tabulated by
evaporator code and can be found below.

1.
Refrigerant charge is approximate since the actual charge will depend on other variables. Actual charge will be shown on the unit
nameplate.
2.
Water capacity is based on standard tube configuration and standard dished heads.
3.
The evaporator charge includes the maximum condenser charge available with that evaporator and is therefore the maximum charge
for a total unit with the evaporator. Actual charge for a specific selection can vary with tube count and can be obtained from the
Daikin Selection Program. The program will not allow a selection where the unit charge exceeds the condenser pumpdown capacity.
