Marine ventilation systems company Delta “T” Systems said it has reconfigured its two 15,000 sq. ft. manufacturing spaces and added tooling and related equipment. The change accommodates the timely construction of the company's new USCG approved A60 Slimline Fire Damper and streamlines the production of the rest of its product lines. According to Delta “T” Systems, the new manufacturing equipment, plus other upgrades throughout the buildings, enhance its efficiency within all of its departments.

Gaining further ground into the offshore crane market, Delta "T" Systems supplied Cranston Eagle hooks to crane manufacturer Appleton Marine, Inc. These cranes and hooks will be used on medium endurance cutters and national security cutters to move small boats into the water from bigger ships and to load cargo. With these cutters used by the US Coast Guard, Appleton Marine needed hooks that met the USCG's specific requirements. That's why the crane manufacturer's FB20-21 and FB90-28 crane models employ Cranston Eagle hooks.

The new DCTV controller is a dual-mode system that can be operated in manual mode or set to automatic mode for worry-free engine room ventilation. In the automatic mode, the DCTV controller…

After a seven-decade odyssey, PT-305 is back home in New Orleans, Louisiana, preparing to serve her country again. Built by Higgins Industries in 1943 for the U.S. Navy, this 78' patrol torpedo vessel sank three enemy craft in the World War II Mediterranean Theater of Operations. PT-305 is now in the final stages of refurbishment at the National WWII Museum's John E. Kushner Restoration Pavilion. Engine room ventilation expert Delta "T" Systems plays a role in this historical vessel's return to service through its donation of 110V fans and DC blowers for PT-305.

Cranston Eagle received approval from the United States Coast Guard for the certification of its new DPR-506-CBH marine off-load hook under the approval number 160.133/77/0. This new, fall-mounted hook is rated at 5,000 kg safe working load (5 metric tons) and bolsters Cranston Eagle's line of USCG certified off-load hooks to five. With more than twenty off-load marine hook models in its line, Cranston Eagle is known around the world for producing one of the most robust and reliable marine hooks on the market.

Circulation of dry, cool air is critical for engine performance, longevity and safety. Delta "T" Systems said it offers a single comprehensive source for all the components that make up an engineered system. Effective marine ventilation requires more than just fans to promote air flow. Equally important in maintaining an optimal engine room environment, moisture eliminators maintain the dry conditions that motors demand, while dampers provide an all-important safety mechanism. The control system coordinates all operations.

The off-load marine hook is found on many workboats and military vessels and is used to launch fast rescue craft and other similar small manned boats from the deck of a ship using a davit or other similar launch and recovery system (LARS). These hooks offer operators the split-second release control often needed at sea and include a self-locking feature, which prevents accidental release while under full load. When all applicable equipment is in good working order, the nature…

Kvichak Marine Industries, Inc., of Seattle, Wash., recently delivered PV Georgia, a 64' all-aluminum Pilot Boat to the Savannah Pilots Association of Savannah, Ga.

A review of resources on the world wide web will quickly produce an abundance of material and statistics on the hazards of marine hook use on life boats, fast response craft, tenders and other vessels. Accidents, injuries and fatalities are far too common when it comes to the operation of marine davit launching systems. Surprisingly, accidents which occur during drills often dominate the statistics, with the second-highest accident counts found during surveys and equipment maintenance events.

Even small vessels can have big exhaust issues in engine rooms and other enclosed spaces. To prevent dangerous fumes from accumulating, Delta "T" Systems has introduced its compact but powerful new 3-inch DC Blower. The 12-volt blower provides extreme air volumes at very high static pressures. This model is continuous duty, rated for long-term reliability. Ideal for gasoline engine applications, it is fully ignition protected. The air mover features a flange mount exhaust port to simplify installation.  Its marine-grade, ABS plastic housing resists corrosion. The stainless steel shaft and bronze bearings provide smooth, quiet operation.  It measures seven inches wide by six inches high.

Delta "T" Systems’ new Head Vent System uses a single powerful blower to extract air from multiple heads on a vessel. It is compact, quiet, highly effective and fully automatic. The entire Head Vent System including the blower, the control unit, and the dampers are housed within a central, remotely-located plenum box. The plenum box measures only 16" L x 12" W x 13" H. A single Head Vent unit is capable of ventilating up to four heads. The system is fully automatic and requires no input from the user. Each head is fitted with a highly sensitive motion detector.

Cranston Eagle, DBA Eagle Products, has signed an exclusive deal for Delta "T" Systems to become the authorized U.S. agent for Eagle Products' full line of offload marine hooks.

Their full line of fall mounted, deck mounted and U.S. Coast Guard certified hooks are used extensively by Canadian and U.S. Navies, Coast Guards, research vessels and offshore platforms.

Long Beach, California, is the second largest container vessel port in the United States. With rush periods now demanding bigger boats with more seating, Jacobsen Pilot Service needed a dependable, new craft to deliver up to eight pilots to incoming ships. They turned to Hike Metal, who supplied a 54 ft. welded aluminum pilot boat equipped with Delta "T" Systems ventilation equipment that provides peak engine performance. To keep the engine room free from damaging salt spray, Hike Metal outfitted the Long Beach Pilot Boat with Delta "T" Systems moisture eliminators. The company also installed axial fans to provide high airflow rates and lower relative sound pressure levels.

Even the bilges of the most well-made vessels usually collect water or other fluids, resulting in foul odors, accelerated corrosion and an unsightly mess. The newest product from Delta "T" Systems leaves those problems in the past. Keeping an eye below deck, the new Arid Bilge Sentry ensures boats stay dry below deck. From a single control box, this system performs two key functions. First, its keeps all bilge compartments bone dry. Secondly, it logs and displays the historical…
