Major U.S. retailer using MRBRAZ ammonia chillers for AC Ammonia 21, March 15, 2017 MRBRAZ & ASSOCIATES, an engineering design firm based in Azle, Texas, has designed and installed low-charge DX ammonia chillers that provide air conditioning in office space at about 10 warehouse locations run by a major U.S. retailer, including four in the

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

Variable Frequency Drive Market Growth

Bryan Kilgore for Zondits, April 3, 2015 A recent market report showed that the variable frequency drive (VFD) market has grown globally in recent years. This growth can be attributed to increasing electricity costs, growing electricity consumption, energy efficiency programs, environmental regulations, and increasing infrastructural development. One potential barrier outlined by the report is a

The Disruptive Innovation of VFD and PMAC Motors

VFD, motor strategies for energy efficiency CSE Mag, January 21, 2015 Motors get no respect. Although they’re present in many of the systems that we design and they often drive the overall energy usage profile of a building, they usually end up as an afterthought. Traditionally, mechanical, electrical, plumbing (MEP), and fire protection designs for

Which VFD Control Method is Most Efficient?

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall performance. Efficiently run motors also use less energy and experience less downtime for greater overall savings.
