Zazz is proud to announce our participation in the 2012 International Workboat Show in New Orleans, Louisiana! This year’s show will take place at the Morial Convention Center from December 5 to December 7, 2012.

The Zazz team will be exhibiting in booth #3812. Stop by the booth for exclusive hands-on demonstrations of our latest products, including the most advanced ventilation control system in the industry: Zazz ATC.

The introduction of this new series is primarily based on two factors: an increasing need for compact, high-pressure fans, and the need for redundant solutions, in case of a motor failure.
Many OSVs (Offshore Supply Vessels) have their intake combustion and exhaust air ports a long distance from the engine room, making it difficult to maintain high static pressures. By having two impellers in a contrarotating configuration, this allows for greater efficiency than two or three separate fans.

Redundancy is also a large factor for many vessels built today. Should a fan motor fail, many classifications require a second fan so that operation can continue immediately. By implementing a single two-stage fan like the Zazz FCR series, builders can save on valuable space and meet requirements for classifications.

In the MRC’s open state, moisture and air from the exterior of the vessel pass into the opening, but note how the moisture adheres to the leading edge of the MRC Air-Foil. The moisture travels along the leading edge to the hook, where it collects and drains out of the MRC. Dry air now passes over the hook and into the vessel’s interior.

Closed:

In the MRC’s closed state, any air or water flow into the vessel interior is stopped by the MRC Air-Foil hook.

The incident was investigated by the USCG, who found that the melting of the filter (pictured above) could have potentially caused the assembly to fall on or into the duct before the damper closed. This most likely would have “interfered with the damper operation and possibly have reduced the effectiveness” of the boat’s CO2 extinguishing system.

The USCG investigators went on to note that 46 CFR 116.610 (b) states that “a ventilation duct, and materials incidental to installation must be made of noncombustible material.” 46 CFR 116.610(c) states that “combustibles and other foreign materials are not allowed within ventilation ducts. However metal piping and electrical wiring installed in a metal protective enclosure may be installed within ventilation ducts, provided that the piping or wiring does not interfere with the operation of fire dampers.” The investigators also noted that “consideration needs to be given regarding the materials used should it be subjected to excessive heat carried by high temperature gases".

Zazz Engineering’s MRC vent system is solidly built in the USA from anodized aluminum and stainless steel. A highly versatile solution, the MRC acts as a moisture-rejecting engine room vent, a fire suppressant/containment device, and a weather closure. Our MRC completely complies with the regulations set by the US Coast Guard, unlike the PVC products sold by our competitors!
