The BOK Center, or Bank of Oklahoma Center, is a 19,199 seat sports and entertainment arena in Tulsa, Oklahoma. The range of events and the scale of the building required an HVAC unit that was both large enough to heat, cool, and ventilate the large arena and quiet enough to not interfere with the acoustics during concerts and events while also being energy efficient. AAON supplied the BOK center with custom modular rooftop air handling unit containing chilled and hot water coils.

The Higher Education Center’s HVAC system provides energy savings, improved indoor air quality, and the use of an environmentally friendly refrigerant to contribute to the building’s LEED Platinum certification. An RL Series packaged rooftop unit with total energy recovery wheels provides cooling for the building’s VAV system and an RN Series make up air unit provides ventilation air to the building’s science labs.

Patricia’s Foods replaced its 10 year old constant volume packaged rooftop units with limited features and no humidity control with AAON RM/RN Series constant volume packaged rooftop units with variable capacity compressors and modulating humidity control. This resulted in elimination of moisture build up on the refrigeration cases and utility bill savings.

Stew Leonard’s newest expansion’s heating and cooling system includes rooftop water-source heat pump units with a variable flow condenser water loop which is connected to the grocery store’s water-cooled condenser refrigeration systems. The energy efficient system reduced the store’s utility costs and allowed the store to receive energy efficiency rebates from the power company and the state of Connecticut.

Allegra Print & Imaging - Tulsa replaced its multizone system with two AAON packaged rooftop units with modulating humidity control. The units are able to control the temperature and humidity of the production space, both critical in a printing facility, in addition to saving money on utility bills. Energy efficient natural gas heating and enthalpy controlled economizers are also featured on the units.

The Citrus College Infant Care Center's packaged DX rooftop units were replaced with HB Series custom quality air handlers, in a packaged unit size. The high efficiency air handlers featured double wall foam insulated construction, chilled water and hot water coils, two speed supply blowers, and economizers.

AAON make up air, packaged DX, rooftop units with AAONAIRE energy recovery wheels were included on both the Carter-Finley Stadium Vaughn Towers, press and luxury box, addition and the end zone locker room addition to provide game day ventilation air.

Replacement Variable Air Volume, packaged DX, rooftop units with AAONAIRE energy recovery wheels and Digital Scroll compressors were used for the classrooms, while Constant Air Volume, packaged DX, rooftop units with AAONAIRE energy recovery wheels, Digital Scroll compressors, and hot water coils were used for the gym and cafeteria.

LEED^® Platinum office building includes R-410A packaged DX rooftop units with evaporative-cooled condensers and modulating humidity control, for the building's UFAD system, and an R-410A packaged outdoor mechanical room with an evaporative-cooled condenser, for the building's chilled beam system.

The large printing facility replaced its old and inadequate mechanical room chiller quickly and easily with an air-cooled packaged outdoor mechanical room and added modular indoor air handlers with chilled water coils.
