Mixed-Flow Impeller Technology Can Cut Energy Costs Drastically

Many facilities that require 100% makeup air for workstation or production environments (typically at research laboratories, pharmaceutical processing plants, and for cleanrooms and isolation rooms) are burdened with extraordinarily high energy costs for heating and cooling. In some cases, it isn't unusual to see annual costs of up to $4/cu ft solely for conditioning makeup air.

Since energy costs represent a substantial part of an organization's operating budget - and since they are rising substantially (probably more than 50% this year over last) - it is prudent for contractors, facility managers, and building owners to seek out new approaches to reduce these costs. One relatively new solution to this problem is to use existing roof exhaust fans that remove ventilation and/or process air from the building. Since this air (and any pollutants) cannot be brought back into the building, valuable heating (or cooling) energy is also being exhausted into the atmosphere.
