Don’t Assume Compressed Air Demand Reductions Provide Proportional Energy Savings

By Paul Edwards, President, Compressed Air Consultants

The purpose of this article is to show there isn’t always a proportionally linear relationship between what happens with flow reductions on the demand side of a compressed air system - and what happens with the energy consumption in the air compressor room. Optimizing an entire compressed air system requires precise knowledge of the supply side, how compressed air is used in the process itself and how those two relate together.

Chillers Provide Temperature Regulation For Fine Wine

By John Medeiros, MTA USA

Temperature control of the musts during the fermentation process is required for the production of high quality wines. Alcoholic fermentation is the chemical reaction in which yeast is used to transform the natural sugars of the fruit into alcohol. The heat generated by this exothermic reaction has to be managed. If must temperatures are allowed to reach the 85°F to 105°F range the reaction will be stopped. This results in high sugar content and an unstable product that requires the addition of sulphur dioxide (SO2) to allow it to be stored without spoiling. In general, optimal fermentation temperatures are 65°F - 68°F for white wines and 77°F for red wines.

Ozone Laundry System Reduces Hotels Operational Costs by 40%

By Marc DeBrum, ClearWater Tech, LLC

Growing operational costs and lower than average occupancy rates spurred Apple Farm Inn and Suites, San Luis Obispo, Ca., to explore economic and facility efficiency benefits obtained through the installation of an ozone laundry system. At the Apple Farm Inn laundry facility, an evaluation was conducted in late 2006 to early 2007, comparing the costs of laundering by traditional methods versus ozone laundering.

Paper Mill Upgrades Air Dryer and Cooling System

By Rich Whitmore

This article reviews two major processes in paper mills: compressed air quality and air compressor cooling. The central air compressor room was expanded and relocated at the largest privately owned paper mill in Canada. The compressor space was required by a plant expansion, which would occupy the original compressor space for increased production.

Benchmarking Energy Performance

By Ed Schlect, PE, CEM, GBE Executive Vice President, Advantage IQ

It’s no secret that cost-cutting is now a main focus for many business owners. When times get tough, the first reaction is figure out where it’s possible to spend less in order to maintain the bottom line. Over the last year, there have been countless examples of companies that eliminated programs, slashed entire departments, and sliced into salaries to protect profits.

Seven Sustainability Projects: Project Implementation

By Thomas Mort, CEM

This article reviews the 7th of the key elements for Low Cost – High Value energy savings. Each of the previous articles reviewed types of projects which are applicable at many facilities. The projects ranged from simple procedural actions such as turning off equipment when it is not making a product to more complex, like adding a water to air heat exchanger and extracting heat from the coolant loops to provide warmed make-up air.

Why Do Steam Traps Fail?

By Bruce Gorelick, Enercheck Systems and Alan Bandes, UE Systems, Inc.

Properly functioning steam traps open to release condensate and automatically close when steam is present. Failed traps waste fuel, reduce efficiency, increase production costs and compromise the overall integrity of the steam and condensate systems. Traps should be tested on a regular basis -- or the neglect may be quite costly.
