Project Description

Steris

Location: Durham, North Carolina

Steris is a leading provider of infection prevention and other procedural products and services. Working in the medical industry, Steris has strict environmental, safety and compliance standards that must be met. When looking for an HVAC system for their new North Carolina facility, Steris needed a solution that could meet all of the high demands of the industry, as well as the complexities associated with the high humidity and temperatures.

Steris’ requirements included

  • An efficient rooftop system.
  • A system that could handle high amounts of outside air and humidity while meeting tight space conditions.
  • Energy recovery utilizing the separated exhaust air stream.
  • Fans that can handle high external static pressure.

To address these requirements, Jacco installed three AAON rooftop units, totaling 121 tons of HVAC. Each of the three units is equipped with modulating compressors, high-turnodwn gas heat, modulating gas reheat and VFD condenser fans to handle the temperature and humidity load common in North Carolina. The units also include direct-drive backward-curved fans equipped with VFDs to handle external static pressure.

AAON allowed for extra space in the units for a run-around coil, which was placed in an exhaust air stream external to the unit and resulted in sensible energy recovery in each unit year-round.

Jacco and AAON were able to devise a tailored solution that met all of Steris’ HVAC needs as well as the required compliance, environmental and medical industry standards.
