Circulation Through Reactor

NOTICE
To prevent equipment damage, do not circulate
fluid containing a blowing agent without consulting
with your material supplier regarding fluid
temperature limits.
NOTE: Optimum heat transfer is achieved at lower
fluid flow rates with temperature set points at desired
drum temperature. Low temperature rise deviation
errors may result.
To circulate through gun manifold and preheat hose,
see Circulation Through Gun Manifold, page
1. Follow Startup, page
To avoid injection injury and splashing, do not
install shutoffs downstream of the PRESSURE
RELIEF/SPRAY valve outlets (BA, BB). The
valves function as overpressure relief valves
when set to SPRAY
open so valves can automatically relieve
pressure when machine is operating.
2. See Typical Installation, with system fluid
manifold to drum circulation, page

A or B supply drum. Use hoses rated at the
maximum working pressure of this equipment.
