Local exhaust ventilation (LEV) is an engineering control measure to reduce employee exposure to airborne contaminants in the workplace. LEV systems capture or contain process emissions and carry them away, minimizing the risk of workers breathing in contaminated air. Although LEV systems vary considerably, common elements include: A hood to capture contaminants (dust, fumes, gas, […]
3D Printing Gas Flows Validation with Multipoint Air Velocity Measurement Laser beam is a type of powder bed fusion found in additive manufacturing (AM) processes that form parts through adding material, rather than subtracting it. Industrial metal 3D printers use laser-based powder bed fusion of metals (PBF-LB/M), where a laser is used to melt and […]
Plant growth chambers and rooms create environmental conditions for healthy growth and controlled environments for analyzing plants. Growth chambers vary in size, style, and features. They may include airflow or ventilation systems, as well as methods to control and monitor lighting, temperature, and humidity, in order to simulate different environmental conditions. Embedded airflow sensors and switches are key […]
The Open Compute Project NIC 3.0 standard simplifies the installation of network interface cards in servers such that any OCP NIC 3.0 card works in any OCP NIC 3.0 server. The standard includes details for the thermal test fixtures which test the cooling capability of OCP NIC 3.0 cards in measured airflow. Degree Controls has the purpose-built […]
Application solutions for airflow and pressure monitoring in cleanrooms, medical device manufacturing, pharmaceutical processing, hospital ICUs, and medical treatment facilities are built on the Rooster™ platform of monitors. With an intuitive, glove-friendly, color touchscreen interface, Rooster™ Monitors are designed for critical containment applications where cleanroom parameters need to be viewed, monitored, alarmed, and communicated to […]
Air purifiers or air cleaners remove contaminants from the air in a room or space to improve indoor air quality. They work by pulling air in, moving air through a filtration system to capture, or neutralize, pollutants and/or particles, and then pushing cleaned air back out. Many air purifiers include a fan. Whether the system consists of HEPA, […]
S100 switch proves airflow & air velocity trip point is user-adjustable! The S100 air velocity switch is a reliable, cost-effective way to monitor airflow. It signals for low flow with choice of NO or NC relay output whenever air velocity falls below the user defined trip point. The S100 trip point is easily set via […]
Demands for increased comfort, concerns about interior air quality, and initiatives to reduce environmental impacts are affecting automotive HVAC system developments. New air modes, air purification, and eco-friendly automotive refrigerants are just some of the items under discussion. To quantify the performance of airflow systems in vehicles, from both the perspective of personal comfort and […]
We know that all respiratory infections, starting with influenza and including the four endemic human coronaviruses, spread more virulently during winter months when people are indoors and closer together. In keeping with this understanding, SARS-CoV-2 has been transmitted more frequently in the Northern Hemisphere because colder weather forces the masses indoors more often and for […]
Rooster™ Ensures Good Ventilation for Chemical Storage Pool venues and chemical storage areas should be well ventilated to minimize hazards and remove airborne corrosives. The CDC publishes the Model Aquatic Health Code (MAHC) to help state and local government agencies improve health and safety in pools. Section 4.9.2 of the MAHC annex covers chemical storage […]
