• Eight �J� type temperature sensors. Five pressure sensors, range: 0 � 10 bar. Two flow sensors
• range: 1.5 � 30 l/min.
• The inlet of vapour incorporates a safety valve to limit the working pressure to 4 bar, and the extractor
• tank and the miscella tank incorporate two safety valves to limit the working pressure to 0.9 bar.
• Electronic solenoid valve and a pressure switch (4 bar).

Flame arrester at the vacuum pump outlet to obtain a suitable ventilation. Any flashback will be

extinguished, so that the unit is not damaged upstream.

• Modes of operation:

Extraction by washing with clean solvent.

Extraction by recirculating miscella.

Desolventising extracted material.

Desolventising miscella.
