NORTHVALE, N.J. - Aerco International Inc. has selected four distributors to supply its commercial boiler and water heating products in key U.S. markets.

The manufacturer chose Barr Mechanical Sales Inc. in Libertyville, Ill., to represent the Chicago market, as well as the northern and northwestern parts of Illinois. Cougar Sales in Houston will represent the company in the Houston market and in southeast Texas. New England Combustion Products Inc. in Weymouth, Mass., will represent the Boston market and parts of New England. Technology Plus, with offices in Albany, N.Y., and Stillwater, N.Y., will represent upstate eastern New York.

Each of these firms can provide consulting engineers and facility owners with HVAC system and design knowledge for Aerco products, Aerco officials said.

"Rising energy prices have contributed to a significant increase in commercial demand for high-efficiency boilers and water heaters. As so many new users and new competitors enter this market segment, it is imperative that a technology leader like Aerco be represented by local sales partners who deliver the superior level of product knowledge essential for effective application of high-efficiency products," said Neil Pilaar, global director of sales for Aerco. "And these firms must be able to support our large customer base as their needs continue to evolve over the long life of an Aerco product."
