Have you ever wondered when it was the right time to change your evaporative cooler pads? When evaporative pads are brand new, they absorb the most amount of water and provide maximum cooling. In addition, the flutes that pass water and air are fully open to exchange as much heat as possible.
There is one guarantee if you live in the Desert Southwest; it will be HOT in the Summer! It is often too expensive to air condition large warehouses so the solution is to use evaporative coolers, often referred to as swamp coolers. The principal idea is to evaporate water to reduce the air temperature being
DL Sales Corporation is proud to be a partner with Columbus Industries. Once recognized at the AHR Expo for the most innovative product, Columbus Industries has designed industry leading high efficiency filters to improve indoor air quality. Combine the lowest initial pressure drops, with MERV 14+ efficiency, and come
There is a newly published guideline related to residential IAQ and how air filters play a role in protecting occupants. ASHRAE Guideline 24-2015 states PM2.5 “may be one of the most significant indoor airborne contaminants in terms of chronic health impact in residences.” The article states MERV 13 or higher is
Have you ever wondered what MERV stands for? MERV stands for Minimum Efficiency Reporting Value. It was developed by ASHRAE as a way to compare different filters. The standard has changed since it’s inception, and it’s important to stay up to date on what is changing. The guide below shows the new efficiency
Arizona Central released the report showing Phoenix ranked among the worst in the nation for outdoor air quality. Hot dry days and lack of rainfall, coupled with windy days, has caused more pollutants to be forced into the air. The fine particles stay suspended for days causing pollution levels to spike.
Have you ever wondered what is in the air we breathe? Studies have been done to characterize particle sizes of known airborne contaminants. Some contaminants cause reactions to the body while others do not. By knowing what is around us, we can determine how to properly remove it with filtration.
Are you certain that the HVAC air filters you’ve specified are the right ones for your facility? Selecting the right air filters doesn’t have to be complicated, but it does require attention to details including submicron particle capture efficiency, energy consumption implications and more.
