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.
