Johnson Controls High Pressure Fan P70AA-118C

The Johnson Controls P70AA-118C is a high pressure control from the P70 series, used for fan control and pressure protection in commercial refrigeration.

The P70 series comprises larger, adjustable commercial pressure controls, distinguished from the compact P100 range by their adjustability and their enclosure. Where a P100 control is supplied with fixed factory settings, a P70 permits the cut-out and differential to be set in the field within its range.

Adjustability is what makes these controls suited to commercial refrigeration, where systems are built to varied designs and operating conditions rather than being factory packaged. A control that can be set to the actual system's requirements is more useful than one that must be selected from a catalogue of fixed points.

It also introduces responsibility. An adjustable control set carelessly, or adjusted by someone attempting to stop nuisance trips without diagnosing them, provides less protection than a correctly chosen fixed control. Settings should be recorded, and a control found set outside sensible limits should prompt investigation rather than simply being corrected.

Head pressure controls applied to fan control cycle condenser fans to maintain workable pressure in cold ambient conditions.

Applications include commercial refrigeration, walk-in coolers and freezers, and air cooled condensing units.
