Next generation from KSB


14 January 2019
KSB Group will unveil its latest generation of high-efficiency circulator pumps at ISH 2019 in Germany.

The Calio S and Calio-Therm S type series are used for heating, ventilation and air conditioning systems, as well as for drinking water circulation systems (Calio-Therm S). KSB says they have been developed for ease of use and compatability with exisiting systems. 
Measurements in KSB’s acoustic test facility resulted in noise characteristics below 30 dB(A), making the new units among the quietest circulator pumps on the market. An LCD field shows the operating mode, current input power, flow rate and head in alternation. If the Setback Operation function is enabled, the pumps identify minimum heat demand when the fluid temperature sinks continuously. They automatically reduce the set point by 30% and, when heat demand rises again, the pumps revert to their previous set point.

For applications requiring heads of up to eight metres, two additional sizes, Calio S 25-80 and Calio S 30-80, will be on offer from mid-2019. The pumps are available in standard overall lengths of 130mm and 180mm in grey cast iron or stainless steel. All 180 mm pumps are fitted with thermal insulation shells as standard.

ISH 2019 is in Frankfurt from 11-15 March.
