Sales Offices in Pbincifal Cities m 1 % H0 Tube Evaporator Tube Condenser McQUAY RIPPLE-FIN COILS m McQuay now makes the famous Ripple Fin coils in three tube diameters, % in., )4 in. and % in., in a wide variety of styles and sizes; for steam, hot water, cold water, direct expansion and re frigerant condensing. "Custom Engineered" coils are readily obtained as McQuay's manufacturing methods provide a wide variety of fin spacings, fin heights, finned lengths, rows deep, and circuiting; thereby both space and capacity requirements can be met. Ripple-Fin coils have all tubes me chanically pressure bonded into the wide smooth fin collars providing a permanent bond and high heat transfer efficiency. McQuay coils are pneumati cally tested under water at 300 psig. Ripple-Fin coils have a staggered tube pattern which combined with the ripple fin produces a turbulent air flow and reduces air "by-pass." In addition to the ripples across the air flow the fins of McQuay coils have rippled edges to give strength and a pleasing appearance. McQuay Evaporators and Condensers are dried to minus 40F. dew point to as sure moisture free coils.
