The MARK III SILENT model has been designed with control systems that allow effective monitoring of operations. The models in this line are equipped with two high pressure hose connections (from 232 to 330 bar) and various control systems: interstage pressure, oil level, cabin internal temperature and direction of rotation detector. They are equipped with option of three-phase motors or single and powerful pumping units, automatic condensate drain and electrical panel to manage the automatic compressor shutdown. Among the available options there is the remote recharging panel. PDF CATALOG

Electrical cabinet 

• ON / OFF switch with motor protection switch.
• Electromechanical pressure switch that stops the compressor at the final pressure.
• Drainage of all separators between the individual stages and also of the final separator during compressor operation.
• Timer for automatic condensate drain.
• Integrated no-load start (automatic drain every time the unit is switched off).
• 5 liter condensate collection tank, with silencer; capacity of about 3 liters, for the ecological disposal of condensate.
• Interstage pressure gauges display the working pressure for the individual compression stages. This pressure information allows you to check the tightness of the valves (inlet and outlet) of each stage and to quickly identify potential sources of failure.

Chassis 

Silenced cab chassis designed and built to facilitate maintenance operations. The tilting motor-holder plate ensures constant V-belt tension. Compressor management and maintenance are facilitated by important devices and tools: the oil level and drain shown outside, the control console equipped with inter-stage pressure gauges, the internal temperature indicator, the presence alarm and incorrect phase sequence, the oil lack alarm and the start stop and manual condensate drain commands.
