Auto Format Form Air Pressure Switch With Dual Ressure Control
Introduction:
1, P series pressure control can protect compressors in
refrigeration and air-condition plant, and keep them from over-low
pressure or over-high suction pressure.
2, P series pressure controls can start and stop refrigeration
compressors and fans of air condensers.
3, P series pressure controls can be used not only in fluoride
refrigeration, but also in air and liquid.
4, P series pressure controls are fitted with 3 kinds of changeover
switch: a single pole double throw (SPDT), a double pole single
throw(DPST) and a double pole double throw(DPDT). The position of
the switch is determined by the pressure control setting and the
pressure at the connector.

The Application:
1. MLSP Series pressure control used in refrigeration and
compressor air system, adjust the equipment is high, low limit
control and avoid the over-low suction pressure and over-high
exhaust pressure.
2. MLSP Series pressure control can start and stop refrigeration
compressors and fans of condensers.
3. MLSP Series pressure control can be used in Pneumatic, boiler,
fire protection, ironing, hydraulic, pumps and other equipment.
4. MLSP Series pressure control with copper air-box connector,
suitable for freon, air, liquid and other non-corrosive media; with
stainless steel air-box connector, it can be used with liquid
ammonia etc corrosive gas or liquid system.
