The state-of-the-art circulators of the Calio type series for heating and air-conditioning systems are available in the most diverse of variants. Naturally, all our high-efficiency pumps meet the requirements of the ErP Directive regulations applicable since 2015.

The Calio-Therm type series provides safe and efficient drinking water supply: Regular circulation enables you to enjoy hot water as soon as you open the tap, and it prevents the risk of legionella.
