In March, Hypertherm, a U.S.-based manufacturer of advanced cutting systems, celebrated the grand opening of a new 160,000 sq ft manufacturing facility in Lebanon, New Hampshire. The additional manufacturing space is expected to facilitate the creation of up to 500 new jobs, including advanced machinist and engineering positions.

Hypertherm designs and manufactures advanced cutting products for use in industries as diverse as shipbuilding, clothing manufacturing, and automotive repair. Its product line includes handheld and CNC systems and consumables, with cutting heads that range from steel-cutting plasma torches to fiber-cutting laser and waterjet equipment.

New Hampshire Governor Maggie Hassan said, following the ribbon cutting ceremony, “I applaud Hypertherm for being a true corporate citizen and a great example of the innovation and ingenuity that exists all throughout the Granite State.”

Effectiveness and efficiency

The company’s reputation for cutting innovation dates back to 1968, with Hypertherm’s invention of water-injection plasma cutting.The company’s reputation for cutting innovation dates back to 1968, with Hypertherm’s invention of water-injection plasma cutting. The associate-owned company has more than 1,300 associates with operations and partner representation worldwide. Hypertherm has been named multiple times by Fortune as one of the 100 best places to work in America.

Evan Smith, Hypertherm president, says exciting developments in the new facility include “an open concept plan with mixed office and manufacturing use. The new plant is expected to receive LEED Silver certification from the U.S. Green Building Council. It is very clean, with lots of windows and skylights to bring in natural light. It contains advanced recycling and filtration systems that help us reduce our costs while improving the performance of our machines,” he says.

“Many of Hypertherm’s buildings are OSHA VPP (voluntary protection program) certified for safety,” says Smith. “Our hope is this building will also be VPP certified. The building is still too new to undergo the certification program.”

Corporate citizenship

“This building contains advanced recycling and filtration systems, pervious pavement, bridges, rain gardens, and solar reflecting roofs,” says Smith. “The first challenge was siting our building in the most sustainable way so that we left the nearby wetlands untouched and took full advantage of the natural beauty of this area. This is a decision you really only have one opportunity to get right, which is why it’s important to the LEED program. Our building is very long and narrow, our paths and parking lots have some beautiful meandering lines, and getting to the building often requires crossing a specially designed pedestrian bridge that is corkscrewed into the ground to leave it barely affected.” This was done to protect the land in its untouched, natural state.

A state-of-the-art building management system turns the heat down, the cooling up, and the lights off when and where needed.“Some of the most innovative decisions we made cannot be seen,” says Smith. “The first critical step to building a sustainable building is to insulate and seal it well from the outdoor elements — deep cold in the winter months and heat and humidity in the summer months. All of our exterior walls have a 6-in. layer of foam insulation and thermal breaks between the structural steel frame. We’ve placed air curtains over the overhead doors to maintain internal temperature.”

A state-of-the-art building management system turns the heat down, the cooling up, and the lights off when and where needed. “This system saves us from requiring as much energy and saves us money,” explains Smith. “This is one of the decisions that required more upfront investment but was made with the long-term in mind. It will allow us to operate our building for decades at a much reduced impact and cost level.”

All of the Hypertherm facility’s energy is from Green-e certified renewable sources, focusing on solar and wind energy sources. “We can’t generate it ourselves on-site right now due to zoning and wetlands issues, but have chosen to partner with third-party verified experts in the field,” says Smith.

Clearly, the innovation that provided the foundation of Hypertherm is carried through the safety and ecology planning of the company’s future. “All of our products go through rigorous life and quality testing that causes us to use a large amount of electricity and water,” he says. “We worked with our inside engineers and outside engineering experts to lessen the amount of electricity and water used through the installation of a closed-loop recirculating cooling system. This has taken our water usage from 50,000 gal down to just a few hundred needed to top off any evaporated volume; saving the equivalent of 1,000 bathtubs a day, or filling an Olympic-sized swimming pool every 13 days. We’re also saving water in our restrooms with low-flow fixtures that save more than 40% fresh water than a conventional building.”

Hypertherm also was able to use its products in the construction of its own building. “Plasma is a perfect tool to use in cutting and preparing structural steel,” explains Smith. “All of the notches, bevels, slots, copes, and bolt holes were cut with an HPR machine, saving time and money. We also sourced the steel for our building with the highest recycled content we could find. Some mills were able to provide us with 100% recycled steel and others were close, giving us an average 77% recycled content in our structural steel.” Sourcing high recycled content is important within the LEED system in order to reduce the use of natural resources.
