Heat Transfer Sales was selected as one of North Carolina’s 2019 Best Employers by Business North Carolina Magazine. We’re pretty excited to announce this is the fourth year in a row that our company has received this honor.
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!!
Typically, we try not to write too much about our company in our blog posts. It's a "me, me, me" world, but we work hard to focus on what specifying engineers, building owners and contractors need from us. Sometimes, however, we need to pass along information about us that may be important to you.
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.
Flower and vegetable greenhouses are not uncommon in NC and SC. While growers in western climates are starting to focus on cannabis, here in the southeastern part of the country, we grow potted plants.
The advent of new products and innovation in the HVAC industry unfailingly starts with the AHR Expo in January. This past week in Atlanta, GA, was no exception. Attendees may have had sore feet, but their enthusiasm didn’t seem to waver on the showroom floor as they engaged manufacturers to show off their latest products.
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.
If you shudder when you think about ice building up on the roof and gutter of a commercial building, you are not alone. Here in the Carolinas, ice can be a tricky foe in the winter months.
