Trinity - One for all

Interrelated savings
Practical base load switch operation


Up to three compressors of various types and sizes with automatic interconnected control - that’s trinity made by BOGE. The necessary connection is integrated in the compressor switch cabinet either already prepared at the factory or easily retrofitted. Alternatively an external wall mounting cased version is available.


The current network pressure is measured by a pressure sensor. You only have to input the maximum and minimum pressure values and all the intermediate pressures of the compressors are automatically calculated.


Extremely flexible:
The adjustable base load switching cycle enables a constant load operation of all installed compressors over a defined period of time.

This balancing of the compressors offers significant advantages as far as maintenance and service are concerned: trinity ensures an even load operation of all compressors minimising service costs. For the selection of various switching times you can choose from 26 channels for three freely selectable priorities (incl. cutoffs, e.g. at night or at the weekend), releasing new potentials for energy saving.
