Bailey Refrigeration Co., Inc.: Solutions

Crowley American Transport
Bailey provided a cargo cooling and dehumidification system for two WOLF Class Maritime Preposition Ships. A specially designed cooling and dehumidification system met the A/C and D/H requirements. In accordance with the MSC specs the equipment was selected to accomplish the dual roles of cooling and dehumidifying the required spaces, while remaining cost effective and simple, both to maintain and operate. The system uses a combination of chilled water air conditioning and desiccant dehumidification, automatically controlled by the same control system required by the government for data gathering. The result is a simple to operate system that was installed at relatively low cost. In addition, the brand of compressors used is the number-1 brand used on ships throughout the world as well as s the number-1 brand for air conditioning in the world, period.

The ample dehumidification capacity allows for only ordinary sealing of the spaces, thus avoiding costly special sealing methods. (We suggested commercially available foam sealant be used to seal all openings not needing daily use such as: hatch covers, ventilation openings, etc.).

By combining all of the cooling, dehumidifying, chilled water pumping, and cargo monitoring in one package, Crowley gained the traditional benefits of a single source. For example, sole source responsibility, simpler procurement and installation coordination, reduction of vendor conflicts, etc.

Princeton Plasma Physics

Bailey Refrigeration, with key cooperation from Cargocaire, produced a 2250 cfm desiccant dehumidification system with direct expansion aftercooling for the Princeton Plasma Physics Laboratory. The skidded system will provide cool dry air to the chamber of the Tokomak, a test machine for cutting edge research in nuclear fusion. The unit was designed and built by Bailey in their Avenel, NJ facility in just 4 weeks! This included submittal drawings, approval, purchasing and receiving required components, assembly, painting, and testing. Similar units have been supplied by Bailey for food production facilities and military cargo preservation, but never on quite so tight a schedule. Custom machinery on budget and on schedule has been a specialty of the company for 50 years.

Mohegan Sun Casino

Bailey Refrigeration has completed one of the most extensive refrigeration installations in the Northeastern United States for '96. The job consisted of 26,000 ft. of copper tubing (liquid, suction, and hot gas lines), all silver soldered, thousands of hangers and penetrations, 85 evaporators (with expansion valves, solenoid valves, and defrost controls), 6 major refrigeration racks, tens of thousands of square feet of walk-in refrigerators, tons per day of ice cubers and flakers, and more. If that weren't enough, the job was being done on a fast track.

The construction of the casino proceeded on three shifts with completion scheduled for October 12th. Despite the usual construction delays, weather problems, and a few equipment problems, the refrigeration was started ahead of schedule and on budget. All work was done under supervision of Bailey technical staff, and conflicts/problems were immediately reconciled by Bailey engineers with manufacturer and architect's engineers. This extra capability made the job go more smoothly and avoided future problems. For example, Bailey engineers recommended the replacement of a refrigerant blend with an azeotrope prior to startup. The result was lower first cost (less expensive refrigerant) and lower future cost (easier to user refrigerant).
