Conecsus Makes Maine Radiator “Greener” through Solder Recycling
By Michael L. Martel, Contributing Editor
durability. You will not find them in your import- ed subcompact car; instead you will find them in rooftop generators, currently a major part of the company’s business, in hospitals, power plants, weather stations, and in heavy equip- ment, such as earth-movers and machines that work in rugged environments. They are also widely used in classic muscle cars, where durability, strength and the ability to dissi- pate a lot of heat quickly is critical.
M
Generating Solder Waste The company does not dabble in cheap
aluminum automobile radiators. All Maine Ra- diator (MAR) products are made of copper and brass and are held together with solder for strength and reliability. Copper, after all, has a very high heat transfer ratio to surface area. Doing a lot of soldering creates metals
waste, primarily dross — the powdery, granu- lar oxide that is the byproduct of soldering, which much be disposed of or reprocessed. Be- cause Maine Radiator uses tin/lead solder, it cannot be thrown away. It is considered haz- ardous waste and must be disposed of in ac- cordance with federal and local environmen- tal laws, which vary from state to state. To be reused, the waste must be re-
processed and purified so that it once again can meet acceptability standards for virgin metal. Also, dross is close in composition to

Maine Radiator uses large amounts of solder to attach the copper and brass of its radiators.
aine Radiator builds some of the best radi- ators in the business, adhering to good old- fashioned Yankee standards of quality and
100 percent metal, and metals are valuable. It makes sense to reprocess the waste and return it to its virgin metal state so that it can be used again. That is what Conecsus, LLC, does, and did for
Maine Radiator, and the significant return on the company’s metals waste was an eye-opener. Conec- sus does not return the reprocessed metals to the waste generator, but rather sells them on the in- ternational metals market, and sends the company a check. The Maine Radiator manufacturing fam-
ily has been in the radiator industry since 1918 and has been manufacturing since the late 1940s. Today, Maine Radiator produces radiators for a wide range of applications, from generators, locomotives, and off-road equipment to over-the-road trucks, high-per- formance cars, and vintage automobiles. Jason Lowit, vice president of MAR,
says,”We were the first to offer all metal cop- per and brass conversion kits to replace plas- tic tank radiators. Our fins and tubes are much heavier than the OE’s. Our copper cores will provide optimal cooling in any shape or size. We’ve built custom radiators for race- cars, street rods, antiques, military units, am- phibious vehicles, industrial computers, over- the-road performance trucks, blimps, the list goes on and on.” He adds that MAR’s heavy- duty and custom radiators are designed to withstand the demands of off-road terrain. Bolted together units are built with extra heavy material added to all vulnerable points and corner reinforcements and solder buildup are standard. “But, our Maine Radiators last up to five times longer than other cores and completes,” says Lowit.
