Recently, the Department of Energy (DOE) released a new requirement that goes into effect on Jan. 1^st, 2017 as part of the "Energy Conservation Program: Test Procedures for Central Conditioners & Heat Pumps.” All manufacturers of heating and cooling systems need to ensure that the AHR units they manufacture for residential and small commercial applications meet this new standard.

One of the biggest concerns after pressure transducers have been installed is knowing how accurate the results will be over time. As a result pressure transducers are replaced more often than necessary or are calibrated with outdated technology. Low-pressure transducers used in critical applications require calibration after extended use to ensure

Total Error Band (TEB) is a measurement of worst case error; it is the most comprehensive and concise measurement of a sensors true accuracy over a compensated temperature range.  TEB is extremely important to know when trying to determine how well a sensor will work within a particular design system. By calculating TEB you'll be able to understand the different possibilities for error. Formulating TEB can be tricky if you don't have the right inputs readily available. 

Happy Halloween From Setra

Have you ever wanted to build your own Haunted House or Spooky Trail?

I'm sure we've all thought about it one time or another. You know what I'm talking about. Places like amusement parks, fairs, or even a homemade one that your “Halloween Crazed” neighbors down the street built themselves. But how do they work?

There are several techniques for managing safe and reliable pressurized rooms in healthcare and laboratory applications. When anterooms are present, such as those used for isolation rooms and pharmacies, it is not always clear how the anteroom should be pressurized in relation to the adjoining room and hallway. 

Successful surgery depends not only on the performance of medical professionals, but also on the integrity of the environment. Relative humidity is a critical component in maintaining the safety and performance of an operating room (OR).

Hospitals are one of the most energy intense buildings on the planet.

As budgets are becoming tighter, many hospitals today are moving towards energy management for cost savings. In breaking down how hospitals can save on energy costs, the first step is to understand what areas of the hospital consume the most energy. Keep in mind that energy consumption varies for each individual hospital based on certain factors such as the hospitals primary function and geographic location.

Engineering proper HVAC systems for critical environments often involves distinct areas of room pressure control and directional airflow. An anteroom between a primary room and corridor ensures a safe airflow buffer zone between the controlled pressurized space and an unclean area. The two spaces are separated by a completely walled area with a door. However, in some applications an ante area without walls or a door can achieve the same effect.

Although mold has many medical uses, it can be a huge problem for homes and buildings, especially if mold growth goes undetected. Mold spores spread easily and can grow anywhere, including carpet, clothing, food, paper as well as drywall, areas inside walls, around leaking or condensing pipes, and above ceiling tiles. Since mold cannot be completely eradicated and can be costly to fix, the best approach is to prevent mold before it becomes a problem. So how do you prevent mold growth? 

Protective Environment (PE) rooms are hospital rooms designed to protect a high-risk immunocompromised patient from human and environmental airborne pathogens. These are positive pressure rooms intended to keep patients safe during recovery from cancer treatment or stem-cell transplant.
