Oil condensing boiler GTU C (from 50 to 291,2 kW)

The GTU C range comprises condensing oil-fired boilers for heating only, with integrated pressure jet burner, equipped with a Diematic control panel.

The GTU C is the result of the latest research which, thanks to condensation technology, has made it possible to considerably improve the performance of oil-fired boilers, in line with current environmental concerns.

Thanks to the GTU C, you can make energy savings of up to 25% and significantly reduce carbon gas and nitrogen dioxide emissions.

The GTU C range is the condensing oil-fired solution for collective needs.

Operating efficiency of up to 104%
A wide output range
Materials perfectly adapted to resist all constraints
A solution that is easy to integrate in any configuration


The GT 530A/AE Series is an eutectic cast iron 4-pass, high efficiency, large net output, low operating temperature, designed boiler. These boilers are specifically designed for oil/gas/propane firing.

The GT 530A/AE is equipped with a service friendly control panel with built-in ON/OFF limit, high limit, manual reset limit and a temperature gauge.

The GT 530A/AE is a Four Pass Design with a generous combustion chamber and horizontal flue passes with fins. The heat transfer is enhanced by the fins and eutectic cast iron baffles. This body design  assures:

  Efficiency up to 87.8%

  Low water pressure drops

  Low noise level

  High thermal efficiency and heat transfer
