If your cooling water is too hot to cool to your desired wort outlet temperature, you will need to use an
immersion chiller in an ice-bath in conjunction with your Therminator
TM
chiller to lower the cooling water
temperature the additional degrees. Since the Therminator
TM
chiller will remove the vast majority of the
heat in a very short period of time, much less ice will be consumed. A 6 m (20 ft) length of 5/8” copper
tube immersed in a ca. 20 L (5 gal) pail of ice and water will usually be sufficient. Pre-chilling the cooling
water, instead of post-chilling the wort in another exchanger, reduces the possibility of contamination
since the cooling water chiller doesn’t need to be sanitized.

Troubleshooting:
Not reaching desired wort temperature:
•
Use graph on page 6 to estimate cooling capacity with the cooling water temperature and flow rate
in your brewery. Water supplies change temperature depending on the season, and flow can
change with varying system water usage.
•
Be sure exchanger is installed at the low point in the system so it is completely full of wort.
•
Be sure unit is operated on its side so all the air is purged from the unit.
•
Unit is fouled from water salts – see “Periodic maintenance” section above
Not reaching desired wort flow:
•
Use graph on page 6 to estimate flow capacity with the cooling water temperature and flow rate in
your brewery. Water supplies change temperature depending on the season, and flow can change
with varying system water usage.
•
For gravity drain systems, you may not be able to meet the maximum flow needed based on
available elevation of the brew pot and restriction of the brew pot drain and hoses. The exchanger
itself adds a negligible restriction (about 0.1 PSI or .6” of water column)
•
Hose diameter too small causing excessive restriction - use a larger diameter hose.
•
Check for blocked or plugged brew pot suction, hose, flow control valve, or exchanger inlet. If
plugged, it is recommended that you install a stainless scouring pad or suction screen to the
suction (inlet) of your brew pot to ensure particulate matter remains in the brew pot. This will also
enhance the flavor and clarity of your finished beer by removing trub from the finished wort.
Sanitation (contamination) problems:
•
Thoroughly read “Cleaning & Sanitation” section above specifically:
•
Ensure unit is cleaned with hot water, PBW, and sanitizer IMMEDIATELY after each use
