Ecology Unit definition
Ecology Unit means an ecology stratum of 0.5 hectares or larger in size which is separated from adjacent ecology strata by a Site Series change.
Ecology Unit means a device used for the cleaning of exhaust air and is listed in conformance with ULC-S647-05, “Standard for Exhaust Cleaning and Recirculation Assemblies for Commercial and Institutional Kitchen Exhaust Systems”. Other terms used for an ecology unit in the industry are ecologizer, Air Purification Unit (“APU”), Pollution Control Unit (“PCU”), “air pollution control device” (NFPA 963, 3.3.3) and proprietary names such as Halton’s (previously known as Vent Master) Ecoloair, Spring Air’s Enviro Unit, Carroll’s EnvironAir, and Quiet-Aire’s Ecology APU. An ecology unit typically has a large metal box in the exhaust path. Generally, the metal box includes 3 large filters plus an exhaust fan, with the fan and sensors controlled by a panel typically mounted in the kitchen area (refer to the diagram in Section II b).
