Air handler: Daikin Applied
Daikin Applied has added natural gas heating as an option to its Skyline™ commercial outdoor air handler line. The gas heat option provides lower operating cost and increased energy saving solutions for building owners and facility managers, while maximizing HVAC system performance, according to the company.
The unit is ideal for new construction and retrofits of buildings without a central boiler plant, or where water piping would be cost prohibitive. Unit installation requires only a single-point gas line connection and a controller, making the air handler virtually a “plug and play” unit. Airtight and weather tight, Skyline outdoor air handlers can withstand harsh weather conditions. Daikin Applied’s patented, gasketed frame channel, double-wall, injected-foam panels and crossbroken top panels help keep conditioned air inside the cabinet and the elements outside.
Skyline’s natural gas heat option features include a burner controller that maintains 80% for higher efficiency throughout the operating range, minimizing liquid condensation on the roof. Low air-side pressure drops keep fan energy consumption at a minimum and closed-loop control sensors monitor current air and fuel flow rates. An onboard controls system with troubleshooting LED is included for quick service diagnostics.
