COOLER FLUID (WATER OR GLYCOL) TEMPERATURES RANGE
Unit can start and pull down from 95
0
F (35
0
C) entering fluid temperature. The design leaving chilled fluid temperature
(LCWT) range as mentioned earlier in the tabulated performance data is
40 to 50
0
F
. The design entering chilled fluid
temperature range is
50 to 60
0
F
. The design cooler temperature drop (
∆
T) range is
5 to 15
0
F
.
The tabulated performance data provided in this catalog is based on a chilled water temperature drop of 10
0
F. Units may
be operated at any desired temperature drop within the range of 5 to 15
0
F as long as the temperature and flow limits are
not violated and appropriate correction factors are applied on the capacity and power input. The COOLINE electronic
selection program can be very handy in selecting equipment at different temperature drops.
It should be noted that temperature drop outside the aforesaid range is not permitted as it is beyond the optimum range of
control and could adversely affect the functioning of microprocessor controller and may also prove to be detrimental for the
equipment.
FLOW RATES AND/OR WATER TEMPERATURES OUT OF RANGE
Certain applications (particularly process cooling jobs) call for flow rates and/or water temperatures that are outside the
above mentioned limits/range. Our chillers can be utilized for these applications by selecting the chiller based on the
specific process load and making a suitable piping and mixing arrangement in order to bring the flow rates and/or water
temperatures relevant to the chiller within acceptable limits.
Example 1:
An application requires 240 GPM of water at 45
0
F and the return water temperature is 65
0
F.
A standard chiller can be used for this application as shown in the following basic schematic layout (single mixing arrange-
ment).
Example 2:
An application requires 192 GPM of water at 65
0
F and the return water temperature is 80
0
F.
A standard chiller can be used for this application as shown in the following basic schematic layout (dual mixing arrangement).
