Commercial growth fuels vent-system manufacturer's expansion.

ALBANY, N.Y. - Vent-systems manufacturer ProTech Systems Inc., has completed the initial phase of its warehouse-facility expansion. The company announced it would increase the facility's size later this year.

ProTech Systems makes the FasNSeal high-efficiency direct-vent system and the FasNSeal W2 commercial vent system. The company credits the commercial market for its growth. Additional employees and positions, especially in engineering, have been added to accommodate increasing demand, officials said.

"We are in a fast-growth mode with our innovative products," said Martin J. Wawrla, owner of the company. "We expect to continue researching and developing additional specialty products for the heating and ventilation market."
