The Importance of Water in Concrete Mixing

Concrete is used all around us as foundation for buildings and exterior surfaces, parking lots, sidewalks, countertops, and more. Although walking or riding a car on concrete is a daily occurrence, it’s easy to overlook the basic elements that go into this essential of modern living. 

Concrete is made of a few basic components:

  • Sand and/or aggregate
  • Cement, comprised of limestone and clay that have been crushed and mixed into a fine powder solution
  • Water

Of these components, the ratio of water to cement is particularly important. Continue reading “The Importance of Water in Concrete Mixing”

Airports Use Dwyer Building Automation System Products

Tapping your foot anxiously, you glance at your airline ticket and the terminal noted on it. The flight will be boarding in a few minutes. As you look around, there are several other people waiting for this flight; it seems the plane is fully booked. You close your eyes and breathe in deeply, calming your nerves. The air seems fresh, not stagnant, despite the large number of people around you. There are no empty seats in the area, so you carefully find a window to lean against as you watch the airplanes of other terminals and wait for your own.

Airports must provide a controlled environment for their visitors, while allowing scheduled maintenance within a building that is operational 24/7. Additionally, they must offer a high level of security for their passengers, all while simultaneously moving those travelers and their luggage rapidly through the building, in a finite amount of time.

Generally, airports are large complex buildings divided into numerous areas, with a number of smaller units located within them. Building automation systems (BAS) are used within airports to monitor and control sensors for things like filters, temperature, air flow, and building energy usage.

Airport automation, put simply, is needed to help ensure safety for world travelers and efficiency for those who make it possible. When an airport’s BAS is functioning properly, travelers can focus on the tasks at hand while everything runs in the background to keep them safe.

Environmental Sensors & Controls for Poultry Houses

Ventilation can sometimes challenge even the best poultry growers. However, it is necessary to maintain both air quality and litter (a mixture of poultry excreta, spilled feed, feathers, and material used as bedding) conditions. Dwyer offers the latest sensor and control technology to help maintain proper environments. By choosing reliable, repeatable, and sustainable solutions, it’s possible to prevent and plan for potential unwanted and detrimental factors that can affect bird health and growth. Moisture (relative humidity / RH), carbon dioxide (CO2), and carbon monoxide (CO) are three major issues most growers will face in the broiler house coming out of the winter season and daily practices throughout the grow process.
