Safety Warning

Full Product Description

Parker’s LLSS Refrigerant Float Switch offers proven and reliable operation by using a mechanical switch and magnet mechanism. This reliability will reduce complexity, reduce replacement costs and offer enhanced system safety. The LLSS uses corrosion resistant components including a stainless-steel float chamber to ensure a long lifetime in the harsh environments of industrial refrigeration.

The Float Switch is used to open and close solenoid valves, to activate or de-activate electrical controls, to energize or de-energize magnetic starters for starting and stopping refrigerant liquid pumps and compressors, and as a safety device, to sound alarms and turn on lights when there is high or low liquid level.

The electrical switch and operating mechanism are encapsulated within a UV resistant transparent housing. The float chamber is hermetically sealed.

Markets:
• Industrial Refrigeration
• Commercial Refrigeration
Features and Benefits:
• Stainless steel float chamber assembly
• UV resistant and transparent switch housing with optional protective cover
• Magnetically actuated switch (single pole double throw)
