Units THE EXCLUSIVE McQUAY RIPPLE-FIN RIPPLE-TUBE COIL ASSEMBLY McQuay hydraulically expanded Ripple-Fin Rip ple-Tube Coils effect permanent contact between tubes and the entire surface of the fin collars--that's the advantage of the hydraulic pressure method--to create the lasting mechanical bond without the use of any "low conductivity" bonding material. This significant advantage is a typical example of how a seemingly small detail in engineering design plays an important part in making superior products. McQuay construction means higher flexible strength with less air friction and cleaner operation. To provide greater flexibility, all headers are of nonferrous tubes, elipted to compensate for any unequal expansions and contractions. All secondary surface is of the aluminum ripple-fin continuous plate type, to give extra strength, and to provide heat transfer surface that remains clean for a longer period, thereby giving greater efficiency; all tubes are electro-tin plated for further protection and longer life. The new standardized design provides 11 header sizes and 19 tube lengths, plus other intermediate header sizes and many other tube lengths. McQuay thus provides greater flexibility for sizing jobs. This careful attention to detail makes McQuay performance possible and establishes their preference among users. McQuay coils are available in a wider variety of styles and sizes, both standard and special coils for steam, hot water, cold water, brine, direct expansion and other applications.
