Davidson Orchards Country Village is a family-run farm and a fantastic place to visit. Check out their website here. The village is open everyday from May 1st to October 31st. Delta-T recently provided the mechanical engineering for their new commercial kitchen. An NFPA 96 range hood was connected to an roof-mounted up-blast exhaust fan. The exhaust ducting passed through several floors and so a fire-rated shaft was required to ensure occupant safety. Fresh air was drawing through a roof mounted supply fan.
