The displacement sensor is used for analogue linear measurements of industrial refrigeration compressors in connection with capacity control. The sensor is available in both a standard and an EX edition. It has a measurement travel of max. 0-25 mm, and can be calibrated for a minimum measurement travel of 0-5 mm. The sensor sends an analogue 4-20 mA signal corresponding to a max. movement of 0-25 mm.

liquid level switch designed for automatic Oil return, when the oil is drained and ammonia surrounds the sensor, the Oil Pot Switch closes the drain valve,

A full design and manufacturing service for industrial refrigeration package requirements, including selection and supply of all level controls, associated shut off valves, pressure relief valves, liquid pumps, heat exchangers and level indication.

Pump Packs: With all liquid pumps, level controls and components assembled, no on-site fabrication is required.

Plate Packs: Available using either semi-welded plate exchangers or plate and shell exchangers.

Cascade Condenser Packs: For use with CO2/Ammonia systems.

Level sensor with a built-in controller for controlling oil return by use of an ejector.
