Accritem
Controllers are reliable, rugged, compact non-indicating
controllers that accurately maintain temperatures in a
wide variety of applications. The sensing element, rigid
or remote bulb, is mounted directly in the medium to be
controlled, and the Accritems response to temperature
change is a proportional pneumatic signal sent to a control
valve.

445 Steam and Water Mixer
(Obsolete)
PowersTM
model 445 Steam and water mixer is a self-contained device
that instantaneously controls water temperature from "cold"
to 200°F. It is designed for economical installation and
operation, requiring no separate reducing valve, temperature
control or shutoff valves. The mixer is pressure actuated
with no outside power source required- mixer automatically
compensates for steam and water supply line fluctuations.
A built-in noise supressor permits quiet operation.
The 445 mixer offers operating savings wherever a steady
steam supply is available. Hot water is generated only
when it is needed from existing steam supply; heat conduction/radiation
losses are greatly reduced.
