For installation in central heating systems,

boiler + buffer

3-way thermostatic valves (groups) ESBE LTC 261 and 271 are

intended for installation in central heating systems with solid fuel

boilers (BioTec-L / -C, BioTec-Plus, EKO-CK P, EKO-CKB P,

CentroPlus, - / B) and buffer tanks CAS, all for the purpose of

protection of boilers from condensation of water vapor from flue

gases.

ESBE LTC 261 and 271 enable quick achievement and maintenance

of the boiler operating temperature by changing the openness

ratio of the return flow from the central heating and short-circuit

installation with the boiler, maintaining the boiler return line

always above 60°C. They have a built-in circulation pump,

thermostatic valve (60°C), shut-off valves, thermometers and

insulation.

ESBE CRA 111/121 is a actuator with a controller for maintaining a

constant return temperature (must be set on 60°C), intended for

installation on 3-way mixing valves from DN50 to DN150. They are

intended for installation with boilers of higher power (from 71-580

kW) when the boiler controller does not protect the return flow.
