Servitec deaerator for system and make-up water
Apaco has built expansion machines for heating and cooling technology successfully for decades. The know-how in pressurisation technology built up over the past decades through design and production is continued with an innovative generation of devices consisting of a new, innovative product line that is revolutionising the expansion market: compressor-controlled Reflexomat expansion machines, pump-controlled Variomat expansion machines, Gigamat expansion machines for large systems and Servitec degasser for system and make-up water.
Automatic Reflexomat expansion machine
For heating and cooling circuits, with unique microprocessor controls that leave nothing to be desired. A variable air cushion ensures controlled conditions in the expansion container. The air and water spaces are separated by a high-quality butyl membrane.
 Pressure maintenance within narrowest limits ± 0.1 bar
 Elastic soft pressure maintenance through air cushions
 Protection of expansion water against incoming air through a high-quality butyl membrane
 Uncomplicated construction, problem-free commissioning
 Almost maintenance-free operation
 Data interface for integration into modern building management
 Activation of Servitec vacuum spray tube degassing possible without a problem
 8 languages can be selected on the display
Variomat expansion machine
Pump-controlled expansion machine combined with degassing and automatic supply feed opens up a whole new dimension. The Variomat guarantees air-free systems up to the highest floor. The atmosphere and water spaces are separated from each other by a high-quality butyl membrane.
 Low investment, high benefits
 Allows bubble-free circulation water through central gas separation
