MARINE WATER BOXES
Marine water boxes allow service access for cleaning of the heat exchanger tubes without the need to break the water piping.
KNOCK-DOWN SHIPMENT
The chiller can be shipped
required to rig into tight spaces. This is particularly con- venient for existing buildings where equipment room access does not allow rigging a factory packaged chiller.
REFRIGERANT STORAGE/RECYCLING SYSTEM
A refrigerant storage/recycling system is a

The following factors can be used to convert from English to the most common Sl Metric values.

In SI Metric, the formula is:
IPLV* = 0.01A + 0.42B + 0.45C + 0.12D
Where: A = COP at 100% Load @ 29.4°C ECFT
B= COP at 75% Load @ 23.9°C ECFT
C= COP at 50% Load @ 18.3°C ECFT
D= COP at 25% Load @ 18.3°C ECFT
