Retrofitting Pneumatic Controls

Despite their age, significant building stock still exist that use pneumatic thermostats and pneumatically actuated valves to control hot water flow through hydronic radiators.

Even when functioning, older Pneumatic Controls
offer limited control and little feedback

While once considered very efficient and technologically advanced, most systems still operating are in poor condition. It is not unusual to inspect a complete building pneumatic system and find at least a third of all valves are inoperative, either frozen in place or no longer reliably opened and closed by the in-room thermostat.

Installation of an Ecovena Thermium system can be an economical retrofit pneumatic controlled systems. The building will not only be converted to electronic controls, but will also benefit from Thermium's advanced energy saving algorithms and controls.
