NH3 Liquid Level Switch - Low Temperature

Technical data: HBSR-SSR-1/IP

The HBSR-SSR-1/IP is a Level Switch with a built-in heater designed to prevent condensation in low-temperature environments. Ideal for freezers and outdoor applications, the switch is typically used to control refrigerant liquid supply to separators and manage liquid refrigerant drainage during hot gas defrost.

Product features

  • Condensation protection: The built-in heater ensures reliable performance in low-temperature conditions, reducing the risk of condensation.
  • Liquid temperature range: Operate across a temperature range of -55°C to 30°C (-67°F to 86°F).
  • Pressure tolerance: Rated for pressures up to 100 bar (1450 psi).
  • Power supply: The switch operates on a 24V AC/DC power supply.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • LED indicators: Provides clear visual feedback when refrigerant is detected.
