Legionnaires’ disease is on the rise. Unfortunately, efforts to prevent Legionnaires’ disease to date have focused on building water systems rather than the municipal water supply. Building water systems are too far downstream to correct the problem, and, as a result, these efforts have been ineffective in curbing the incidence of legionellosis.

It is unrealistic to place on building owners and operators the burden and risk for providing pathogen-free water throughout buil

When outside temperatures fall below freezing, water inevitably forms into ice. Open cooling towers can be susceptible to freezing due to their inherent nature of operation. As a result, ice formation becomes a subject of management, not elimination. Fortunately, there are alternative solutions.

Closed circuit coolers are used for a multitude of niche applications, but are ideal for evaporative cooling applications in severe winter climates. If ice formation is not managed properly, e

Operator training has become one of the most prevalent areas of deficiency in Process Safety Management (PSM) Programs for refrigeration systems today. High turnover in the refrigeration industry coupled with high complexity system designs and an increasing void of technicians trained in foundational trades are the perfect storm for compliance challenges among operators of large refrigeration systems today.

Packaged systems provide many features, attributes and documentation that will

EVAPCO’s advanced cooling solutions help realize massive power savings and vastly reduced maintenance. The 17-story, 380,000-sq-ft building was constructed in 1981.

Goals:

• Find a long-term solution to outdated cooling infrastructure
• Prioritize energy efficiency
• Minimize maintenance
• Controls to optimize operation of the entire mechanical system
• Streamline water treatment

Solutions:

EVAPCO initiated an in-depth study to investigate the formation and control of white rust. This study, which began over three years ago, led to the development of industry-leading research equipment specifically designed to evaluate white rust formation on evaporative heat transfer surfaces. A small-scale closed circuit cooler was designed and built to replicate the dynamic conditions associated with evaporative cooling equipment commissioned with immediate heat load.

In addition

A coil-cleaning program should be an integral part of maintaining some kinds of process cooling equipment.

Most people think of coil cleaning as a building or facility prepares to turn on the air-conditioners for another season. Admittedly, spring is a perfect time to put such cleaning and maintenance at the top of the to-do list. Condenser and evaporator coils are an integral part of HVAC systems, and one of the quickest and safest ways to maintain them is through a comprehensive coi

WellSpan Gettysburg Hospital was looking to modernize mechanical systems to ensure reliability of critical patient-care functions.

Constructed in 1921, WellSpan Gettysburg Hospital in Gettysburg, Pa., has undergone a number of changes over the years. According to Joe Lehigh of the facility’s engineering team, the most recent were made chiefly to improve hospital operations.

“The key need was to modernize mechanical systems that would assure reliability of critical

Background
EVAPCO, Inc. recently introduced new Evaporative Condensers and Closed Circuit Coolers which utilize extended surface coils. For decades extended “fin” surfaces have been used on heat transfer coils, often referred to as “finned coils” primarily in an effort to increase dry capacity. However, in the past the fin material was limited to carbon steel tubes with a “round profile” prior to hot dip galvanizing. In most cases, the

Scope
The purpose of this paper is to provide specifying engineers, purchasers and users of evaporators in industrial refrigeration applications with an explanation of “total heat” versus “sensible heat” selection methods and how the method used can impact coil capacity, fan horsepower, physical size and first cost of the equipment.

This paper provides technical information for engineers, purchasers and users; such that, they have a bet
