TRU-TEMPERATURE DIAGNOSTIC SYSTEM
Background
The first model of Humidaire Unit to display actual water temperature for the benefit of
gin personnel was the model HU-60-1106C. This was an improvement over prior models
that provided no temperature display.
On the HU-60-1106C, if the actual water temperature is far below the desired water
temperature, this is shown on the display, but not always understood by the operator.
Instead of adding moisture to the fiber, this condition dries the fiber because of the low
relative humidity of the heated air. In gins where personnel understand the significance
of the water temperature and monitor the water temperature display closely, excellent
performance is achieved.
The TRU-Temperature diagnostic on the HU-SOUTHWEST Humidaire model is
designed to automatically and continuously monitor water temperature for the operator.
By performing this function, it provides consistent performance from the Humidaire Unit
for all users, experienced and novice, by prompting personnel when a water temperature
problem occurs.
TRU–Temperature Explained
TRU-Temperature stands for “Timed Response Under-Temperature.” It is designed to
notify users when a common problem occurs with the HU-SOUTHWEST Humidaire
Unit such as low water temperature. Low water temperature can be caused by clogged
water nozzles, a malfunctioning float valve, a problem with the Humidaire burner, a
problem with the water pump, or other potential problems. Water temperature is the most
important variable to be watched while monitoring the performance of a Humidaire
System.
To assist the ginner in watching the water temperature, the TRU-Temperature logic
monitors the difference between the desired water temperature and the actual water
temperature. If a low water temperature condition persists for more than 30 minutes the
Humidaire Unit is turned off and a message is displayed.
