27th Sep 2016

We are delighted to announce that we are despatching the first Calder-built offshore vacuum unit in accordance with the recently introduced, February 2016 edition of the DNV Standard for Certification 2.7-2.

The latest edition of the DNV 2.7-2 standard for offshore service modules introduces a range of safety measures which provide even greater protection for both the equipment and the offshore environment in which it operates. Among the upgrades are: lockable doors when closed with fire resistant seals; integral gas detector; IP56 rated within 1m of doors and louvers; portable fire extinguisher system; power safe in the event of a failure, and externally accessible fuel shut-off valve.

This vacuum unit from our MultiVac range is rated up to 24” Hg (810 mbar) and up to 2,270 cfm (3,856m3/hr). Our equipment is ideal for the harsh conditions of the offshore Canadian waters in which this unit will operate.
