Notes: Always use a backup wrench to support the unit piping
when making connections. Make sure all external piping
is supported independently of the unit.
We recommend that you have strainers installed on the
cooling water inlets and customer-supplied shut-off valves
on all piping connections. Use common black welded pipe
for permanent installations.
The unit is designed to operate with an open, unrestricted
drain line. Steam rapidly expands within the heat
exchanger, so any overpressure condition from
backpressure or standing columns of water against the
drain must be avoided.
If you must use a pipe joint compound, use a compound that can withstand the high
temperatures and pressures of your unit. Always insulate all piping to prevent burn hazards
and to retain heat. Make sure insulation is properly rated for maximum operating
temperatures of your temperature control unit.
Piping Considerations for Mobile Installations
Because your portable hot oil temperature control unit is fitted with casters, its portability is
well suited for multiple applications. You can purchase high-quality flexible metal hose from
the manufacturer to enhance the mobility of your unit; state the length you want when
ordering.
Although they cause a drop in pressure, you can also install quick disconnects to your unit.
However, do not install check valves with quick disconnects unless absolutely necessary!
