Cost-Savings ComparisonFor a Deeper Clean Airport personnel invested time and effort to compare the expected lifecycle costs of central preconditioned air and point-of-use equipment. The research by CVG staff supported by AERO Systems Engineering indicated that a central system would last longer, be more durable and provide resilient, expandable infrastructure to serve CVG now and well into the future, Weller reports. Constructed with insulated, triple-walled polypropylene piping, the airports new central system is expected to last more than 30 years. The polypropylene piping is designed to resist corrosion and provide better insulation than steel piping. Additionally, an insulated Photo courtesy of Meridian Regional Airport glycol delivery system across passenger boarding bridges is expected to improve ROUTINE CLEANING OF RAMP, RUNWAY, & ROADS thermal performance of cooling aircraft.Removes FOD that can hide in cracks & crevices Other operational benefits of the central system include: Model 600 HSP Options Dual-compressor chillers allow maintenance or repair on half of the chiller while still running at 50% capacity.Chassis Mounted Magnet removesLiquid Recovery System removes ferrous metals at sweeping speedsand recovers standing liquids, suchRedundant pumps keep the system up to 25 miles per hour. as glycol. 100% operational while workers repair or maintain single pumps.Lateral Air Flow Nozzle clearsRunway Sweeper, High Speed debris, such as sand, grass andPerformance.Smart valves optimize glycol flow to each snow from runways and taxiways. air handling unit by monitoring the flow and inlet/outlet temperatures.
