The Boling Vision Center project involved the renovation of a 23,250 square foot optical vision clinic, in Elkhart, Indiana. Kalamazoo Mechanical installed the HVAC, plumbing and medical gas piping. The HVAC system incorporates three roof-mounted packaged units (RTUs) that include HEPA filtration capability. The duct work runs on the roof to conserve space in the surgery rooms below. The project’s laser room is served by a Liebert air handling unit that precisely controls the climate in the room. A new medical gas vacuum and supply system is provided throughout the building. The building is heated through the gas-fired RTUs. Two new, on-demand water heaters serve domestic water needs. The Boling Vision Center is also equipped with a fully integrated, web-based temperature control system. This medical facility required the highest level of air quality, temperature and humidity control. Testing and balancing the system was essential to satisfying the demanding environmental tolerances.
