Some air quality management districts (e.g., those in New Jersey and Southern
California) require temperature measurement of the gas stream at the outlet of the
last heat exchanger on the cooler. Perma Pure offers a 1/32-inch diameter
hypodermic-style type K thermocouple that can be inserted into a special heat
exchanger (i.e., it has a small port for insertion of the thermocouple) so the actual
sample dew point temperature can be measured. This is sometimes referred to as
the New Jersey thermocouple outlet temperature option.
If the cooler is run as a single stream, the final heat exchanger will have a New
Jersey thermocouple to sense the temperature inside the heat exchanger. A
quantity of two (2) NJ thermocouples are required when the cooler is used for dual-
stream simultaneous conditioning.
In the Baldwin
™-Series eCOOL 5000™, this New Jersey Thermocouple can be
connected to one of the extra thermocouple inputs for readout. Alternately, for a 4-
20mA output, the optional isolator board should be purchased.
