About Us

Controlled Environments Group is your best source for gravity-actuated mechanical dust control baffle systems in the USA. We supply Burnley® Baffles, a reliable and proven way to accomplish dust suppression in receiving pits, rail and truck dump hoppers and wharf hoppers. Alone they reduce emissions 70% - 80% without using any energy. 100% reduction can be achieved with as little as 25 cfm/sf of hopper entry area. Use smaller fans and ducts in new construction; get the benefit of energy savings from day 1 and for the life of your facility. Very low maintenance required if any.
