Connecting Process Piping
! CAUTION
• Hoses, valves and other components in your process must be able
to withstand temperature control unit maximum temperatures and
pressures.
• Maximum temperatures and pressures are listed on the unit
nameplate.
• Carefully inspect all components before installation.
• If in doubt about component suitability, obtain factory
components.
• Fix all leaks! Fluid can be a potential fire and slip hazard.
Connecting Cooling Water Piping
You must provide cooling water at 25 psi to 75 psi (172.4 kPa to 517.1 kPa/1.7 bars to 5.2
bars) for proper operation. Untreated water can foul or corrode the heat transfer surfaces,
slowing water flow and causing fluid temperature control problems. We sell a complete line
of water treatment equipment that can reduce downtime and maintenance costs.
Run properly-sized cooling water lines-never smaller than the outlets on the portable hot oil
temperature control unit. If external piping is larger than unit connections, reduce the size of
the piping at the unit.
Connecting Vent Piping
You must leave the vent connection open to the atmosphere at all times. The vent
connection is located on top of the reservoir. On systems with piping above the reservoir
level, you must run vent piping to a minimum height of one foot (1’ / 31 cm) above the
highest point in the system. Run the piping down into an auxiliary vented overflow chamber,
such as a vented, covered 55-gallon (208-liter) drum. This practice ensures that overflow will
not create a hazard to personnel.
Remember: All external piping must be supported independently of the unit.
