RESIDUAL HEAT HEATS AT VIRTUALLY NO COST.

The use of residual heat for infrared heating: A quantum leap in space heating technology. Since the
development of O.P.U.S. X, it has been possible to use the residual energy in the exhaust gases of infrared
systems economically. For example, for the hot water-based heating of offices. Or with the air-to-air heat
exchanger O.P.U.S. Air in halls without hot water consumption points.

O.P.U.S. X

O.P.U.S. X is the heat exchanger system for infrared heating. And a technological highlight. After all, the use of residual heat in infrared heating systems (radiant tube heater) has so far only been economically feasible in exceptional cases. With the development of O.P.U.S. X, the breakthrough has been achieved.

UP TO 15% EXTRA ENERGY. THE PLUS FROM KÜBLER.

The KÜBLER heat exchanger system enables the economical use of energy that was previously largely lost
to the environment in the exhaust gas of hall heating systems. Up to 15% additional energy can be
recovered in this way. Can be used, for example, for heating offices and social rooms. Or also for hot
service water. Virtually free of charge.

By the way: O.P.U.S. X is economically interesting not only for new installations. KÜBLER's residual heat
can be integrated into existing infrared heating systems as required.

THE FUNCTIONAL PRINCIPLE.



O.P.U.S. X extracts the energy contained in the exhaust gas from infrared heaters (radiant tube heater) and transfers it to a storage medium. Usually to water. This hot water is stored in a buffer tank. As a standard application, the energy is then fed into the heating circuit return of a pump hot water heating system via a controller as required. In this way, the recovered energy can be used to heat offices or social rooms. Or for the provision of service water. Other possible applications include (fresh) air preheating.

O.P.U.S. Air

THE AIR-AIR HEAT EXCHANGER FROM KÜBLER.

Heat recovery increases the efficiency of heating systems. The demand for these solutions is rising
accordingly. But what can you do in halls without hot water customers? Our Research & Development division has developed a new system for this: O.P.U.S. Air – the air-to-air heat exchanger from KÜBLER.

RESIDUAL HEAT FOR LOW HALLS.

Developed for halls without hot water consumption points: O.P.U.S. Air.
This heat exchanger generates warm air. Can be used, for example, to heat low hall areas.





EXTREMELY COMPACT. AND VERY EFFICIENT.

Technically, heat recovery is achieved with this condensing technology from KÜBLER using the
countercurrent process. Or with plate heat exchangers in cross-flow process. Depending on the
performance class. The compact design provides significantly higher heat transfer surfaces than
conventional tube-in-tube solutions. And thus very high firing efficiency. Depending on the system
configuration, up to well over 100%.

Versatile. The performance spectrum.
O.P.U.S. Air is available in various capacities up to 225 kW. For single or collection units. For the most individual requirements. Even in smaller and lower halls. Always when there is no need for hot water, but the efficiency plus residual heat is to be used.
