Equipment Performance:
This healthcare client had just verified the committed funds required to renovate and add operating suites to an existing Operating Room (OR) area. The new area had to be in service in less than four months! Both the engineering consultant and the hospital had worked with Air Enterprises in the past and were very pleased with Air Enterprises' performance and equipment. Through the working relationship familiarity and by releasing equipment upon order placement, Air Enterprises was able to ship equipment in less than (12) weeks. The consultant, the hospital, and Air Enterprises had numerous working meetings within the first two weeks to ensure equipment issues, coordination efforts and project timing were ensured.

With the equipment operating at 11 inches of static pressure, casing deflection and casing air tightness were critical. Air Enterprises constructed the unit enclosure of all double wall aluminum panels which were interconnected with a unique interlocking, high tolerance extrusion system. The system was guaranteed to maintain less than a 1/200 deflection criteria and to maintain a leakage rate of less than 1/2%.

Unit components consisted of a vertically oriented return air plenum fan, a Class III DWDI supply fan, variable inlet vanes with factory mounted operators, full energy economizer/controlled air mixing section with dampers & air blenders, steam humidification, chilled water cooling coils, hot water heating coils, 30%/95% filtration, and discharge sound attenuators. A 4' wide piping vestibule was also supplied to house the integral piping on this rooftop unit. A lighting system and fan disconnects were factory installed. Air Enterprises supplied start-up, owner training, and field joining field services.
