While oxygen is unquestionably the most important gas in our atmosphere, as it is essential for most animals and human life, nitrogen is the most widely used atmospheric gas.  Nitrogen is the go-to gas for countless industrial, medical, and scientific applications. This is because nitrogen is in vast supply, inert, and possesses the desirable characteristics of being colorless, odorless, and tasteless. The purity of nitrogen significantly affects the outcome of the application for which it is used and how the industry measures the purity of nitrogen gas is the focus of this article.       

Without compressed air monitoring, up to 30% of the compressed air generated goes to waste. This waste occurs for several reasons, including leaks caused by failures at joints and tubes, exposure to vibration and normal component wear, and the suboptimization of machines and devices. Continuous monitoring capabilities allow operators to detect leaks and other anomalies in their early stages. By addressing pneumatic issues before they can grow, companies can reduce compressed air use by 20% to 30%. 
 

Do you know and track the annual generated nitrogen energy cost per SCFM? Do you know what factors drive this value and what action you can take to control the optimum lower levels? In this article we intend to illustrate the magnitude of potential wasted energy dollars when the compressed air system and the on-site nitrogen generation system are not properly monitored and controlled.

The AIM (American Innovation and Manufacturing) Act was finalized by the US government at the end of 2021. This legislation introduced a phase-down plan for virgin HFC gases. From now through 2036, the US will reduce the production and importation of virgin HFCs by granting relevant businesses a set number of HFC allowances (or quota), which will decrease over time. 

One of the components frequently included in a reciprocating air compressor is an air receiver, often referred to as an air tank.  Proper air storage is a critical component of intermittent duty cycle because for brief moments, the system can provide more compressed air than would otherwise be provided by the compressor pump. The capacity of compressed air piping also contributes to the total capacity of the air storage system.

Centrifugal air compressors are known for reliable longevity, but at some point, end- of- serviceable- life decisions must be made. Your centrifugal compressor has been the lifeblood of the factory for upwards of twenty-five years, or longer, but it is finally showing signs of giving up the ghost. Much like when the aging family automobile continues to rack up increasingly more expensive repair bills, operators of aging centrifugal compressors face the decision to repair or replace the machine when the maintenance costs reach a certain threshold. 

Weftec 2023, a leading event for industrial and municipal wastewater treatment facilities took place October 2-5, 2023 at Chicago's McCormick Place. The objective of this article is to provide readers with a sampling of aeration blower technologies on display at the show. We regret not being able to include all exhibitors or visits made due to article length considerations. 

If your vacuum pump is malfunctioning, you are faced with a choice: repair or replacement. Our guide will take you through both options and provide recommendations on when it makes sense to repair vacuum pumps and when to replace them. We will also take a look at how to spot and diagnose common issues before they lead to system failure.
Whatever the path of action, the decision to repair or replace always begins with testing and diagnosis. A factory-trained service technician who specializes in vacuum pump services inspects the equipment and identifies the problem.

In October of 2023, eight hundred sales professionals from forty-one countries attended the EVAPCO Global Sales Conference in Baltimore, MD. Under the theme “Full Spectrum Evolution,” EVAPCO celebrated the talent of its global sales network, and the evolution of its full spectrum of heat transfer solutions. This article will recount the event functions and share new developments unveiled at the EVAPCO Global Sales Conference, the first since 2017. 

The impact of compressed air on industries globally is undeniable, spanning from small tire shops to vast oil and gas sectors, as well as specialized domains like laboratories and pharmaceuticals. Amid this industrial transformation, many have taken control by employing in-house air compressors, air dryers, and related equipment to autonomously generate compressed air. In-house compressed air generation eliminates the need for relying on external sources, whether through cylinder bulk packs, Dewars, or tankers delivering compressed air.
