Apprentice steamfitters use donated cooling tower for hands-on training
Steamfitters UA Local No. 602 Mechanical Trades School, with training centers in Landover, Md., and Springfield, Va., recently expanded and renovated its training facilities. The union, which represents journeymen, apprentices and helpers working in the heating, air conditioning, refrigeration and process piping industries, sought equipment donations to outfit the school and help with its apprenticeship training mission.
The school offers a five-year apprenticeship and trains a diverse group of more than 700 students aged 19 to 70. Apprentices are assigned to a union contractor and jobsite, and generally work 40 hours per week. Classes range from soldering and brazing, health and safety, and drawing and blueprint reading to basic and advanced refrigeration and electricity.
Assistant Training Director James Balderson explains that the nonprofit school has a very small equipment budget, so he has to think creatively to beef up the equipment available for HVAC training. He is the coordinator for the school’s HVAC department, and trains air conditioning, refrigeration and boiler technicians.
“Being able to expose our students to real equipment gives us a greater advantage compared to teaching out of a book,” he adds. “Classroom time is necessary, but we must reinforce it with hands-on training.”
Balderson notes that he and other instructors regularly ask vendors if they know anyone discarding equipment. “If they are going to replace equipment and it’s still usable, we’ll arrange to come get it,” he says. “Hands-on knowledge is the most important part of the steamfitter’s trade, so the ability to have access to real equipment to solve real-time problems is essential in the industry.”
He developed a long equipment wish list, at the top of which was a cooling tower and a small boiler. Word got out about the school’s request and Balderson was approached by Ryan Kern at Cummins-Wagner Co., an employee-owned industrial and mechanical equipment distributor headquartered in Annapolis Junction, Md.
Balderson knew Kern from his years working in the trade. Kern made the rounds to a variety of manufacturers to solicit equipment donations. Cummins-Wagner also supplied products from its inventory, including Bell & Gossett pumps and a Lochinvar FTXL boiler. In Christmas-in-July fashion, Kern was able to supply the school with all its wish-list items.
SPX Cooling Technologies agreed to donate a factory-assembled single-cell crossflow Marley NC 8401 cooling tower. Originally constructed as a demonstration cooling tower for trade shows, the tower is typical of what students would see in the field every day, making it an excellent fit for the school. “When I was in the field, the Marley brand was known as one of the superior cooling towers out there, so I was happy when I heard we had an opportunity to get one for our program,” Balderson says.
Both Cummins-Wagner and SPX support the union and the trades, and were onboard with helping them meet their training needs. “We are committed to the students’ education and are excited to get the equipment into the hands of the next generation of pipefitters and HVAC technicians,” Kern says.
Cooling tower central to training
The cooling tower is key to the students’ hands-on training. When it was delivered, the apprentices helped install the tower, and now it is being used to cool one of the new classrooms.
The instructors also use the tower in conjunction with other pieces of HVAC equipment in the classroom. The availability of real operating equipment allows instructors to intentionally put “faults” in the system as it runs, so they can train students to troubleshoot. When the system shuts down — for example, a pump that has stopped pumping water or a fan no longer pulling air through the heat exchanger — an apprentice is tasked with identifying the problem and fixing it.
“We could buy trainer units, but having the real thing is so much better,” Balderson explains. “A working cooling system where I can place faults that HVAC technicians have to fix is the best way to train. They can process firsthand how important it is to properly maintain equipment and components, and how water treatment is critical to product lifecycle.”
He adds: “Without these kinds of equipment donations, we could not provide the education we do. They help us educate our apprentices to a high level.”
