Accritem Controllers are reliable, rugged, compact non-indicating controllers that accurately maintain temperatures in a wide variety of applications. The sensing element, either rigid or remote bulb, is mounted directly in the medium to be controlled, and the Accritem's response to temperature change is a proportional pneumatic signal sent to a control valve. Typical applications are instantaneous or high capacity storage water heaters, compressors, lube oil coolers, shell and tube heat exchangers, diesel engine cooling systems, oil preheaters, 100% outside air make-up units, and specific processes such as parts washing, die casting, and plastic molding.
