In a world of constantly changing approvals and requirements, is it realistic to expect a customer to stay up-to-date with the latest and greatest information? Things that were once deemed acceptable are now found to cause serious health complications. Consequentially, there are all kinds of agencies in place designed to keep products safe, regulate material composition, and educate the consumer.

Particularly something like lead, which according to the CDC ,“[…] can affect nearly every system in the body.” Continue reading “An Introduction to Lead-Free Product Requirements”
Air balancing a distribution system is needed to properly direct the air flow in order to optimize the system’s design. Flow rates are tested, adjusted, and balanced as cubic feet per minute (CFM) or cubic meters per hour (m3/h). There are two traditional methods for balancing airflow at the terminals. The first is sequential balancing, which involves setting the zone and branch dampers in sequence. However, the most common method of air balancing is called proportional balancing.
Dwyer offers several carbon dioxide measuring products that use non-dispersive infrared sensors as the sensing element. Carbon dioxide sensors are commonly used in building automation systems to monitor air quality. The level of carbon dioxide is indirectly proportional to the amount of people in a space and can be used to adjust ventilation for the space.
