Nitrogen booster

The Nitrogen Booster is used to load accumulators — individually or within an HPU — with nitrogen at the correct preloading pressure, transferring gas from the cylinder to the accumulator down to a minimum pressure of 20 bar in the cylinder itself.

The nitrogen preloading pressure of bag and piston accumulators must be checked periodically (approximately every 3-6 months) and, if necessary, corrected to the required value.

These checking and refilling operations must be carried out without back-pressure on the oil side: for this reason, before working on the accumulator, the oil side must be disabled and drained using the manual cut-off and decompression valve.

The Nitrogen Booster is connected to the electrical system and to the nitrogen cylinder via the "IN PB" coupling, and to the accumulator to be refilled via a hose connected to the "OUT ACC" coupling.

It is also available in the Ex Model (ATEX) version, for use in explosive atmospheres.
