Process Cooling & Equipment rings in the new year with some exciting changes.

As I write this issue's commentary, Christmas is less than a week away. With two young children at home, my husband and I are beginning to suffer from "jingle bell blues." The hustle and bustle of tending to the details of family visits as well as last minute shopping have begun to take their toll. I am looking forward to my few days of rest and hope to sneak some time with a good book.

If you're looking for a good read on water treatment for enhanced condenser tubes, curl up with this issue of Process Cooling & Equipment. Michael Scholnick of Garratt-Callahan Co., Milbrae, Calif., explains how the design of internally enhanced condenser tubes requires careful water treatment to avoid premature corrosion or failure. Enhanced tubes increase heat transfer, but their increased surface area and helical groove design demand vigilant attention to water treatment. Find out how to maximize the service life of an enhanced-tube condenser bundle to help boost your company's bottom line and improve overall efficiency.

If you would rather chill out by learning about cryogenic systems, then "Selecting the Right Temperature Sensor" is the thing to read. Joe Yeager of Lake Shore Cryotronics, Westerville, Ohio, explains that the proper selection of temperature sensors for cryogenic applications depends on two keys points: knowing what needs to be measured and how well it needs to be measured.

And if you are in the market for a cooling tower, you won't want to miss our "Cooling Tower Roundup." Towers from a range of manufacturers are showcased along with product specifications and contact information.

This issue also boasts great columns from our regular contributors. Enviro-Watch's Mark Harbin discusses 13 of EPA's accepted alternatives to CFCs and HCFCs. In part one of a series, Paul Puckorius talks about "Cooling Water Treatment vs. Cooling Systems" in his Water Works segment. In this installment, he identifies water treatment needs. In his column on ammonia refrigerants, George C. Briley explains why he thinks training is an important investment that can pay big dividends. He offers suggestions on where to send your staff for schooling.

On another note, I am sure you noticed that Process Cooling & Equipment arrived in your mailbox with some company -- its sister publication, Process Heating. As the cliche goes, the only thing that remains constant is change. So, for 2002, we selected PH readers that use industrial cooling equipment in their operation and are sending both PCE and PH to them. It is our hope that the sister publications help you in your business. Always, I appreciate your feedback. Let me know what you think.
