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 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 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.
