The Engineer’s Guide to MRI-Compatible Products
When it comes to selecting air inlets and outlets, magnetic resonance imaging (MRI) rooms need special consideration due to the unique equipment found in the room. MRI rooms, often referred to as magnet rooms, contain MRI machines that use powerful magnets to produce pictures of anatomy and physiological processes of the body. These magnets create a magnetic field, which makes the material choice of air inlets and outlets a key factor in the design of the air distribution system.

Exploring the Benefits of Displacement Ventilation in Schools
For years, studies have linked healthy environments in schools with improved educational outcomes for students. We’ve seen that indoor air quality has a major impact on health, performance and attendance and that quiet classrooms improve academic performance, reduce stress and encourage better behavior.

Working with Active and Passive Beams in Cold Climates
For applications in climates that require a significant amount of heating, owners, engineers and contractors often wonder if chilled beams are an appropriate choice for their projects. Since the “chilled” part of the chilled beam name only specifies cooling, can you also produce heat with a chilled beam?

A Look at These Standards and How They Impact Terminal Unit Acoustics
Sound-power and sound-pressure levels are used to catalog acoustical performance for terminal units. The sound performance of a terminal unit is crucial when considering the comfort of occupants within a space. For example, some places have an open-ceiling design and are well suited to quiet units to minimize distracting noises.

Ultra-Compact Energy Recovery for Anywhere Space Is at a Premium
When SolutionAir launched the RegenCore alternating mass-exchanger energy-recovery unit in 2019, the unit rocked the industry, delivering up to 92% effectiveness and no preheat requirement down to outdoor temperatures of −40°C/F. Its energy-recovery cores and four-damper design maximized energy conservation and minimized leakage, but combining the components meant RegenCore needed to be either mounted on a roof or concrete pad outdoors or installed in large mechanical rooms indoors.
