Everyone Wins with Tennessee Tech University Industrial Assessment Center Program

By Mike Grennier, Compressed Air Best Practices^® Magazine

Launched in 2006, the TTU-IAC program provides manufacturers in the state with free energy, productivity, and waste assessments – including best practices for compressed air systems, and blowers and vacuum, as well as cooling towers and chillers. The assessments to date have provided manufacturers in the program with \$27.48 million in recommended cost savings, equaling 3.82 trillion British thermal units of energy savings.

International Wire Compressed Air System Upgrade Recovers Heat

By Brian Sorbello, Rogers KNW Series Northeast Regional Manager, Rogers Machinery Company

While late summer may not be the time of year many of us think about heat recovery, the potential for energy savings in compressed air systems should be on our minds year-round. For those involved with the compressed air systems within International Wire Group’s facilities, energy savings is on their minds each day. This culture of continuous improvement has everyone on the lookout for savings wherever possible.

Energy Management at Visteon

Compressed Air Best Practices® Magazine interviewed Jennifer Meier, Global Energy & Engineering Manager, at Visteon Corporation.

There are three main segments in Visteon's climate group are climate systems, powertrain cooling and engine induction. Climate systems include refrigeration compressors, fluid transport, heat exchangers, battery cooling modules, climate controls, auto defog/demist systems, and multi-zone HVAC systems. Powertrain cooling systems include heat exchangers (radiators, condensers, charge-air, exhaust-gas), airflow management, and diesel and hybrid thermal management. Engine induction includes air induction systems and intake manifolds.

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.

Printing Facility Reduces Air Demand

Ron Marshall, CET, CIM, Manitoba Hydro

This article will focus on a compressed air system assessment done at a printing facility in Canada. The energy costs at the time, in Manitoba, were \$0.025 per kWh and the installation was of just 65 horsepower of air compressors.

Seven Sustainability Projects: Heat Recovery

By Thomas Mort CEM

Reducing energy costs and pollution emissions involves many areas within an industrial facility. My studies have found seven (7) key (or common) areas where low cost practical projects can be implemented. Combined, these projects provide savings exceeding 10% of the annual energy spend with an average payback of less than one year. This article will focus on the opportunities for using waste heat sources to supplement winter building heat.

Sustainability at RR Donnelley

Compressed Air Best Practices interviewed Michael D. Manzella. Mr. Manzella is a Senior Vice President, Environmental, Health, Safety and Quality (EH&S), and also the Chief Sustainability Officer for RR Donnelley (RRD).

Sustainability at RRD starts with a philosophy. It is then executed through a global policy and objectives. RRD’s philosophy does not see sustainability as making a choice between being cost-effective and improving environmental impacts. On the contrary, sustainability represents integrating these two factors. This philosophy guides our sustainability objectives and strategies.
