What Is This Equipment?

A pressure control switch is an automatic safety and control device that continuously monitors system pressure.

When pressure reaches a pre-set value, the switch changes the status of its electrical contacts to:

  • Start equipment
  • Stop equipment
  • Generate alarms
  • Activate protection systems
  • Protect compressors and refrigeration plants

The Saginomiya SNS-C106X60 is commonly installed in:

  • Refrigeration Compressors
  • Provision Plant Compressors
  • Air Conditioning Systems
  • Chiller Units
  • Cooling Water Systems
  • Auxiliary Machinery Systems
  • HVAC Plants

Without proper pressure control protection, compressors may suffer severe mechanical damage, excessive wear, and costly downtime.
