FORRY

FORRY, Inc., founded in 1978, was one of the earliest innovators of microprocessor based control for electrostatic precipitators (ESPs).  Later it was purchased by the Solvera Controls company, which itself was purchased by Stock Equipment Company in the year 2000. Under Stock’s ownership, FORRY has been able to develop new products and pursue many new markets. FORRY products are used by some of the largest utilities in the U.S., such as AEP, Detroit Edison, Duke and others. FORRY also provided controls to plants in Asia, Europe, South America and the Mid-East.

FORRY's initial products involved microprocessor controls for precipitator rapping. This technology expanded to include microprocessor based voltage controls in the early 1980's. Since that time, FORRY has introduced three new generations of rapper controls and four new generations of voltage controls, all reflecting the combination of new electronic technology and increased customer expectations.

In the late 1980's, FORRY introduced the first integrated precipitator management system capable of online monitoring of plant conditions and dynamic control of precipitator performance to achieve the optimum balance between plant conditions and precipitator power consumption. Since then, FORRY has continued to add functionality. The current system integrates rappers, voltage controls, opacity measurements, boiler load measurements and a DCS interface into a common control system. FORRY’s suite of Windows based applications gives operators superb monitoring, control and data logging abilities.
