Characteristics of a good quality ecology unit Kitchen affluents are released into the surrounding environment in the form of heat, contaminants, grease particles, moisture, and organic volatile compounds. An exhaust fan alone is not enough to eliminate odors and pollutants from the kitchen. Trosten features ecology units that is considered as ideal solution for commercial kitchens, hotel, and hospital industries. Here are some characteristics of a good ecology unit. An ecology unit combines a washable aluminum pleated filter, synthetic bag filter and an electrostatic precipitation which maintains a good standard of safety and hygiene for those who work in a kitchen environment that needs to be clear of effluents that are transmitted daily. ● It has a sturdy design which allows all its panels to be dismantled and cleaned. ● According to the industry specification, the ecology units should be fire rated. ● They will have a multistage filtration for effective oil, grease, smoke, and odor removal. The gas passes through an aluminum filter that traps large dust particles. It then moves on to the synthetic bag filter which traps any microns that got through and then to an electrostatic precipitator that electrically charges the particulate matter. The charged particles pass into a collector plate made up of a series of parallel plates that collect the matter. ● It should have UL certified filters. ● Contains UL certified filters which ensures that the HVAC system is of a higher efficiency rate. ● Refillable units have activated carbon filters and support the climate.
