High Pressure Blower For Saturated Air Exhaust In Energy Recovery.

Markair was asked to help make improvements to an existing energy recovery unit that takes hot process air off the brewkettle and uses that heat to create hot water. The original system created a great deal of moisture on the roof top leaving the roof slippery and unsafe. It also led to corrsosion of adjacent structures. The new design included at Twin City Model RBO Industrial Blower and Munters Mist Elimintator. The new design is working perfectly. It is the driest the roof has been in years. The new design also reduced the noise levels on the roof.

Aerovent Fans: A Sure Bet on the Trump Casino Vessel

Leave a Comment

Trump Casino

Atlantic Marine, the shipbuilder, wouldn’t gamble on just any fan product. Atlantic Marine worked with Markair, Inc. to purchase Aerovent fans, thereby eliminating delays in approval, and maintaining their design integrity in providing their customers with a quality product and on-time delivery.

In all, forty-two Aerovent Type “W” Direct Driven Vane axial

Fans were supplied for the Trump Casino vessel project.

Lay Pitman & Associates, the naval architect, uses our computer fan selection program along with the expertise of Markair engineers to specify the Aerovent equipment, to select the quietest sound levels, provide stable fan curves, and determine adjustable pitch fan blade angle settings.

For this project, fan sizes range from 18″ to 33″ diameter, powered by both single speed and two speed motors designed to meet the weatherproof requirements for IEEE 45 and USCG 259 marine-duty, below-deck service.

Aerovent’s Type “W” vane axial fan was chosen for this project based on its proven performance and reliability on several other passenger vessel projects where Aerovent marine-duty vane axial fans have been installed.

The Type “W” vane axial design provides both the engineer and ship owner a simple, yet very versatile fan for shipboard uses.

What makes the Type “W” vane axial the right fan for the job? We think there are five advantages:

Wide Performance Range: Performance requirements for the Trump Casino project varied from 1800 CFM to 20,000 CFM with up to 2″ of static pressure. Direct drive Type “W” vane axials are available from 18″ to 84″ diameter, 1200 CFM to over 200,000 CFM and up to 4″ of static pressure.

Compact Design: Fan housing lengths are usually equal to or less than the fan diameter keeping installation space to the bare minimum. The available space for mechanical equipment is always a major design consideration especially on luxury passenger vessels.

Quiet Operation: Due to the fan’s close proximity to sleeping quarters, restaurants and public areas, the allowable noise levels from the fan are very stringent. The Type “W” vane axial is known for its smooth, stable performance and quiet operation.

Manually Adjustable Fan Blades: Adjustable aluminum fan blades make it possible to alter the airflow during final balancing of the supply/ exhaust system.

Rugged Steel Housing Construction: Heavy gauge flanged housings are built for bulkhead mounting. For ease of installation, the motor leads are extended to the exterior of the fan casing for making all electrical connections.

The complete order was shipped three days ahead of schedule. In a letter from Atlantic Marine’s Mr. George Haynes to Markair, he states, “We certainly appreciate vendors who can help us meet our production schedules and furnish quality products.”

Markair & Aerovent provides fans for NASA Space Shuttle Program

2010 is
 the final year for NASA’s aging space shuttle fleet. As 
each orbiter returns to earth from its final voyage, it is greeted by 
products designed and sold by Markair, Inc. and manufactured by TCF Aerovent.

NASA Cooling Unit

Once the orbiter lands at the end of a mission, the Shuttle Landing
 Fleet of vehicles keep systems on the orbiter operating while it
progresses through checkout stages. One of the fleet support systems is a
portable air conditioning unit. TCF Aerovent supplied twenty (20) panel
 fans for each of three (3) of these portable air conditioning units.

The existing cooling
air supply units were not performing to specifications and required new 
fans and 
coils. The fans and coils had to bolt to an existing shroud and provide
higher performance.

 seacoast environment required special materials and
 coatings for corrosion protection. Quality, performance, and delivery
 were very
 critical requirements of the specifications.

Each of the three units required sixteen (16) 30″ DDP 
fans and four (4) 16″ DDP 
pre-cooling fans for a total of sixty (60) 
fans. The motors were severe wash down duty with stainless steel
shafts, and hardware. The fans were all welded aluminum construction 
to fit the existing shrouds. The coating was a white Ameron paint that
sand blasting, an Amerlock 400 primer and an Ameron PSX700 topcoat.

In addition to the extensive documentation and testing
requirements, NASA STD-5008 required a Certified National Association of 
Corrosion Engineers (NACE) Inspection of all of the fans. Aerovent
 hired a NACE 
certified company out of Pompano Beach, 
Florida to perform the 
inspections and to provide the certified reports. Aerovent provided a
 QC person to work with the NACE inspector. Together, they reviewed the 
specifications and inspected everything from surface 
preparation to measuring dry film thicknesses (DFT) on each fan. The 
painting and inspection process
 took a total of six days. The detailed report states “all work was 
performed in strict accordance with specifications and in a professional

For the past five years, the Aerovent units have been
 operating during landing and recovery of the space shuttle fleet. NASA
very satisfied with the quality of Aerovent’s products and the units are
performing to specifications.
