Page 16 Portable Hot Oil Temperature Control Units
Make sure that the unit location is not in a confined space to ensure proper air circulation.
Special air circulation/ventilation is required for units operating at temperatures exceeding
500ºF (260ºC). Vapors can escape from areas such as the reservoir tank during high
temperature operation.
!
CAUTION
Harmful vapors may be generated from thermal fluid
during high temperature operation.
Prolonged or repeated exposure of these hot-generated
vapors may result in eye and respiratory tract irritation.
Avoid contact or inhaling harmful amounts of material.
Consult the Material Safety Data Sheet (MSDS) for
precautions and instructions for the thermal fluid you
are using.
Note: Before storing your temperature control unit, make sure
you remove all residual water with compressed air to
avoid a potential freezing hazard. See Section 6-3 on Page
35 for more information.
Note the following table of ambient temperature ranges permitted for storage and operation:
Ambient storage range Ambient operation range
ºF ºC ºF ºC
-40ºF to 185ºF -40ºC to 85ºC -4ºF to 120ºF -20ºC to 49ºC
You should preheat the process heat transfer fluid first if you want to start the unit below an
ambient temperature of 30ºF (-1ºC).
3-3 Connecting Piping
Make sure that all external piping is properly sized to reduce external pressure drop as much
as possible. Do not install process or water supply/drain piping smaller than the fittings on the
unit. If the water supply piping is larger than unit fittings, reduce the pipe size at the unit.
