Coltri Mark III Silent

8393,00 8782,00  w/o VAT

The Mark ІІІ Silent model is designed with control systems to effectively monitor all operations: interstage pressure, oil level, internal cabin temperature and rotation direction detector. With two connections for high pressure flexible hoses, it is equipped with electric motors and powerful pumping units, automatic condensate drain and electrical panel for managing the automatic compressor shutdown. Available options include the remote charging pane.

One of the fundamental parts of the compressor: the motor transfers the motion to the pumping unit through the belt. On this model is available the single-phase or three-phase electric motor from 4 to 5, 5 kW.

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.

  • 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.
