Liquid Level Switch - Low Temperature

Technical data: HBSC2-SSR-IP

The HBSC2-SSR-IP is a refrigerant switch designed with a built-in heater to prevent condensation in low-temperature environments. It is ideal for use in freezers and outdoor applications, often employed for controlling the supply of refrigerant liquid to separators or managing the drainage of liquid refrigerant 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 150 bar (2175 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 a clear visual signal when refrigerant is detected, improving monitoring and safety.
