Air Compression Solutions Reduce Manufacturing Energy Costs

Boosting Energy Efficiency: Air Compressor Technology IEN, November 25, 2016 Faced with increasing competition, high energy costs, increased regulation and more aggressive sustainability goals, facility owners and plant managers are under extraordinary pressure to reduce costs, while achieving greater productivity and energy efficiency. Most industries use some form of air or gas compression to generate

compressed air heat recovery

Compressed Air Heat Recovery Basics

Daniel Stewart, ERS, for Zondits Compressed air is a notoriously expensive energy source but one that is widely used in commercial and industrial settings because of its ability to be easily stored, the high output-to-weight (and output-to-size) ratio of pneumatic actuators and tools, and the low maintenance requirements of end-use devices. As a general rule

Compressed Air Applications in Theme Parks

Daniel Stewart, ERS, for Zondits Compressed air is often referred to as the “fourth utility” in commercial and industrial settings – joining water, electricity, and thermal fuels – because it has a wide variety of applications and is often essential to process and facility operation. Major advantages of compressed air as an energy source include

Cannon Mountain Upgrades for More Snow This Year

Valerie Eacret, ERS, for Zondits Cannon Mountain, a ski area in the White Mountains of New Hampshire, is making a number of significant changes to its snowmaking equipment and energy supply systems in preparation for the next ski season. The plans for the upgrades indicate that the operation will use only two-thirds of its current

Size Matters: All Air Compressors Are Not Designed Equally

Sizing matters: How to avoid oversizing or undersizing your compressed air system Plant Services, April 7, 2016. Image credit: blickpixel Common downfalls of undersized and oversized compressors The most common issue resulting from under-sizing compressors is insufficient airflow to production equipment. Workers may complain that their tools aren’t working properly, or that low-pressure alarms may be

A Compressed Air Energy Storage Technology Review

Compressed air sustained pumped hydraulic storage Intelligent Utility, March 15, 2016. Image credit: gr8effect The development of deep water compressed air energy storage (DW CAES) involves placing weight ballasted inflatable bags on the seafloor or submerged on a lake bed, with an air pipe connecting between ground level and submerged bags. It is a variation of

Ask the Expert: Refrigerant & Regenerative Desiccant Compressed Air Dryers

What is the difference between refrigerant-type compressed air dryers and regenerative desiccant-type compressed air dryers? What are the advantages and disadvantages of one over the other? Karamvir Singh for Zondits, January 4, 2016 Answer: Let’s start by answering why you even need to dry the compressed air. The atmospheric air contains water vapor that begins

The process is seemingly simple: combine high-pressure air with water at a low temperature, and you
