Alpha Immersion Circulators

LAUDA-Brinkmann Alpha Immersion Thermostat can be used with any bath that has a wall thickness of up to 30 mm by means of the included screw clamp. It is suitable for use with non-flammable liquids (water or water/glycol mixture). Using the additional pump circulation set and a cooling coil, the immersion thermostat can be expanded to form a full-fledged thermostating system.

The circulator features a large, 3-button single-line LED display with integrated shut-down timer that automatically initiates stand-by mode when the programmed routine completes. Variable flow rates can be achieved using the included inserts and fittings – the front cover removes without tools.
