Refrigerant Float Switch Assembly Replacement with DIN Plug

These Hansen refrigerant liquid level float switches (HLL Series) are used to electrically indicate or control a liquid level by opening or closing a SPDT switch. Their simple, reliable design provides long life performance for almost any application. These refrigerant liquid level float switches are typically installed on a vessel's liquid level column. They can control liquid level by controlling a liquid fill solenoid valve. Often, they are used to provide high level cut-out or alarm.

In addition, they can be used to turn off a recirculating liquid pump if a low level occurs. Other applications include control of liquid level via a liquid exit solenoid valve, level indication via a pilot light, and transfer drum operation. This switch is sealed in a clear housing to allow visual confirmation of switch action but protection from tampering. In addition, the switch is surrounded by an inert gas which provides an environment which inhibits corrosion. For ease of installation, switch assembly position rotates 360°.

The HLLSWE refrigerant float switch assembly is a product with both side and bottom connections, but also comes with a DIN Plug. Connection sizing is ¾" (20mm) FPT/ 1" (25mm) butt-weld combination style. Compatible refrigeration systems include Ammonia, R22, R134a, CO2 and other approved refrigerants.
