To freeze dry a blueberry, an ice cream sandwich, the latest-greatest-pharmaceutical or a formaldehyde-infused complex carbon chain; one must first freeze the liquid water (or other liquid compound) into solid ice that is integrally bound within the food or other moist substance. 

In order to properly identify the performance requirements of a blower it is necessary to identify the inlet and discharge pressures. The friction losses in the inlet and discharge piping must be calculated to determine the total pressure requirement. This article details a simplified procedure for calculating piping losses.

When cold weather approaches, safeguarding the performance and longevity of your vacuum pumps becomes a top priority. Cold conditions pose unique challenges that can affect the reliability and efficiency of these crucial industrial components. At Busch Vacuum Solutions, we understand the importance of winterization in preventing corrosion, freezing and other potential damage. In this guide, we’ll share tips to ensure your vacuum pumps continue to operate optimally during the colder months.

Many designers and operators believe that multistage centrifugal blowers are not suitable for variable speed control. They also feel that multistage centrifugal blowers are an inefficient option for wastewater aeration. Implementing VFD control of their aeration blowers allowed the plant to improve energy efficiency. The reduction in energy expense paid for the system upgrade in less than two years.
