Koch Heat Transfer Co. LP has purchased the Alco, Alco-Twin and Bos-Hatten brands of heat exchangers from Peerless Mfg. Co.

The brands are known for engineered-to-order heat transfer equipment. Alco and Alco-Twin specialize in hairpin double-pipe and multi-tube heat exchangers. The Bos-Hatten brand is known for shell-and-tube heat exchangers. Peerless acquired the brands in 2008 through the purchase of Nitram Energy Inc.

Koch Heat Transfer expects the acquisition to help the company expand into additional markets. PMFG Inc. is the parent company of Peerless, and Koch Heat Transfer is a subsidiary of Koch Chemical Technology Group LLC.
