New Actionair Marine Fire Damper Designed for World Wide Application

04 October 2007 15:56

Ruskin Air Management has launched an updated and improved version of the successful Actionair A-60 Marine Fire Damper.

Units are now available in an extended range of sizes from 100mmx100mm up to 1m square, with the option of multiple units to meet the needs of even larger applications.

Actionair's A-60 Marine Fire Damper was the world's first to achieve the coveted USCG-EU MRA Certification. Every unit also bears a stainless steel plate showing the distinctive 'ship's wheel' logo that symbolises Marine Equipment Directive compliant (MED) approval and an individual number so that it can be tracked throughout its life cycle.

Other key approvals include Lloyds EC Type Approval (Module B), Germanischer Lloyd Approval, Lloyds Certificate of Fire Approval and American Bureau of Shipping Certification.

Ruskin has achieved major success with the Actionair A-60 Marine design - particularly with builders of fast ferries and luxury yachts. Orders have been won from both European yards, including those in Italy and Germany, and as far afield as Australia and Chile.

PURPOSE DESIGNED

Purpose designed for application in marine and offshore projects, Actionair A-60 Marine Fire Dampers provide a complete solution for fire safety requirements in association with ventilation and A/C systems. All units are corrosion and vibration tested.

In its latest enhanced format the Actionair A-60 incorporates an electric actuator option with a 60 second reset time, an LED indicator on the Electrical Thermal Release (ETR) and a more versatile Pneumatic Thermal Release (PTR) design – which takes only three seconds to rest!

A-60 Marine Fire Dampers feature aerodynamic, stainless steel interlocking opposed blades, operated by a 'failsafe' spring mechanism. 'Failsafe' is achieved by means of a unique and patented Electrical Thermal Release (ETR), which operates automatically at 72oC, or if the power supply is interrupted.

A manual test switch permits periodic operation of the damper for test purposes, simulating actual 'failsafe' release under fire conditions. A green LED lamp is now built into the ETR housing - giving clear and simple visual confirmation that the actuator is receiving power, the ETR is correctly fitted and the thermal fuse is intact.

A-60 Marine Fire Dampers are available for use with both rectangular and circular ductwork. They can be used in systems with maximum pressures up to 1500Pa and duct velocities to 15m/s. Models are suitable for both vertical and horizontal applications with airflow in either direction.
