2-1 Models Covered in This Manual
This manual provides operation, installation, and maintenance instructions for portable hot oil
temperature control units. Model numbers are listed on the serial tag. Make sure you know
the model and serial number of your equipment before contacting the manufacturer for parts
or service.
Your portable hot oil temperature control unit circulates thermal transfer-type oil through
your process and precisely, automatically, and reliably maintains it at a temperature you can
select. Portable hot oil temperature control units are sized to meet the specific requirements
stated by the Customer at the time of purchase.
2-2 General Description
The operating range of your temperature control unit is from 100°F to 550°F (38°C to
288°C). The unit is best suited for use with a specially formulated Heat Transfer Fluid. A
recommended list of commercially available heat transfer fluids can be obtained through
Customer Service.
Rapid recirculation of the relatively small amount of fluid provides a close and uniform
temperature relationship between the TO PROCESS and FROM PROCESS lines. This does,
of course, depend on the configuration of your process, and any restrictions within the mold.
This recirculation, combined with the immersion heater and optional cooling capability, gives
fast and accurate response to bring the fluid up to temperature, or to changes in the settings
when needed.
Performance is assured through matching the unique controllers to the high temperature
system. The two systems are fully integrated to achieve accurate control, along with efficient
use of water and electricity.
