Contactors Protectors Relays Controls

Pressure Controls are for use in refrigeration and air conditioning systems to give protection
against excessively low pressure or excessively high pressure. Pressure controls are also used for starting
and stopping refrigeration compressors and fans on air-cooled condensers.

Pressure Controls are fitted with a single-pole double-throw (SPDT) switch. The position of the
switch is determined by the pressure control setting and the pressure at the connector. They are available in different enclosures. Traditional models are mechanically operated based on spring return. Electronic controls are also available which works based on pressure sensors which acts more precisely.

Differential Pressure Control is used to rectify under pressure and over pressure issues in different sector, making the overall pressure of the system ideal for prefect working of system.

They are available for different refrigerants, corrosive or non-corrosive.

• Advantages,
• Protects system from over pressure and under pressure
• Maintains overall pressure on different sectors of system
