KSB: New high-efficiency circulators for OEMs

Monday, January 23rd, 2017 von admin

The high-efficiency circulator range Calio SI type series are intended for use in heating, air-conditioning and solar power systems where they facilitate automatic operation with constant-pressure or proportional-pressure control as well as operation with 0-10 V setpoint input or external control via PWM signal in accordance with VDMA-Einheitsblatt [Standard Sheet].

On the HMI, Dual and EcoMatch variants the user can select the required mode of operation via two pushbuttons on the control panel.

KSB: New drinking water circulators

Monday, February 15th, 2016 von admin

160127_CalioTherm_0033The new high-efficiency circulators of the Calio-Therm S NC series are maintenance-free glandless pumps designed for pumping drinking water in closed circuits, which are commonly found in single-family or two-family houses as well as in larger building projects.
Like the other Calio pumps the new circulators offer a high-efficiency permanent magnet motor to achieve top efficiencies. With one-touch operation the flow rate can be adjusted via three speed levels. In the event of a blocked rotor the motor stops automatically, and a fault is indicated. Three LEDs display the operating status. The screwed connections are available in dimension Rp ½ internal thread (EN 10266) or G 1 ¼ external thread (DIN ISO 228). The maximum flow rate equals 0.7 m³/h. The pump’s maximum head is 1.0 m. The drinking water temperature should measure between +5 °C and +65 °C.
