Alpha Refrigerated Circulators

LAUDA-Brinkmann Alpha Refrigerated Circulators are the cost-effective choice in the area of high-quality LAUDA thermostats. The cooling technology of cooling thermostats RA 8, RA 12, and RA 24 enables cooling performance through the entire temperature range of -25 up to 100°C. The well-priced equipment range is made possible by minimizing any unnecessary features, with the focus on reliability and user-friendliness.

The thermostats are suitable for operation with non-flammable liquids (water, water/glycol) and for both internal and external thermostating tasks. A 1-point-calibration of the thermostats can be carried out by the user. Operation is simple due to the fully-electronic continuous controller and simple 3-key operation with user-friendly menu prompts. A one-line LED display shows actual or set temperature.

Units include low level and over-temperature protection with both acoustic and visual alarms. The deep-drawn stainless steel bath is durable and the circulating pump provides excellent control for flow reduction. An electric connector controls through-flow cooler DLK (On/Off/Automatic). A drain connection at the rear makes maintenance easy. Bath covers and pump kits are included standard.
