HVAC and plumbing design engineers have a tough job. They’re tasked with creating comfortable building spaces while optimizing energy usage and maximizing space. Naturally, they need to do ALL of this while minimizing the budget and ensuring that the HVAC system will last until all the people who remember the project have retired. (Granted, the latter half of that statement was a joke…sort of.) While we always recommend working with our sales engineers for the best system selection for your application, we understand that engineers may want to do some quick calculations prior to enlisting a manufacturer’s rep.

About us
Water is our business, so we take every opportunity to remind colleagues and friends of its importance. March 18-22 is National Fix a Leak week. An entire week is set aside to celebrate water by reminding us not to waste it. Those little drips add up to a significant amount of money and wasted resources. Keep in mind how much energy goes into moving water and how much water goes into making energy. Save water and you save energy. It can be easy being green!!

About us
The idea of replacing the boilers in an existing central energy plant can be daunting. This is very high capacity, very large, and very pricey equipment. The renovation can take a long time and require extensive modifications to the existing mechanical room. The logistics of getting the old equipment out and getting the new in is a full project by itself.

Air in a hydronic HVAC system can be a problem, specifically when it comes to the development of corrosive iron oxide. When system components, like pump volutes or expansion tanks, made of cast iron or steel are mixed with oxygen and water, corrosive iron oxide is formed. Commonly known as "black sludge," iron oxide includes magnetite. Magnetite is a naturally occurring brownish-black or black material that is extremely fine and becomes a black, sticky mess inside hydronic systems. Magnetite can get into valves and ECM motors. It can also build up on the surfaces in a boiler or heat exchanger and act as an insulator to reduce heat transfer and system efficiency.

We're so thrilled to be a part of a thriving commercial building industry in NC and SC. 2018 has brought many challenges and we've worked hard with engineers, building owners, and contractors to bring new (and old) HVAC and engineered plumbing projects to life. A coming new year always inspires reflection and goal-setting. In that spirit, we're sharing the top 10 blog posts of all time while we take some time offline to review topics that may be of new interest in 2019.

Conventional commuter trains are generally limited to a top speed of 60 miles per hour. The train speed is limited by the track condition, curvature, and elevation changes. It takes a lot of energy to move that big, heavy equipment up and down the track. Additionally, the train must overcome rolling resistance between the train wheels and the track to get to higher speeds.
