About Filtrine Manufacturing Company

In 1901, inventor George Kneuper patented a new type of filter medium which used molecular attraction to remove microscopic particles from water. He named this material "Filtrine" and founded the Filtrine Mfg. Co. in a small brick building in Brooklyn, NY. Mr. Kneuper's filters were soon installed in many of the new high-rise office buildings in Manhattan. Gradually Filtrine developed a reputation as the engineer's choice for drinking and process water filtration around the country.

Over the next nine decades, Filtrine has outgrown plants in Brooklyn and Waldwick, NJ and was headquartered in the picturesque but bustling mill town of Harrisville, NH until January of 1999, when Filtrine once again outgrew its facility and moved to a larger, more modern facility in Keene, NH. Filtrine water filters are installed in the White House, the United Nations Building and in thousands of other fine buildings around the world. In addition to the small sediment filters first developed by Mr. Kneuper, Filtrine now manufactures industrial filtration systems with capacities up to 560 gpm to remove sediment, rust, taste, odors and many cancer-causing chemicals. We also offer ultraviolet sterilizers to kill bacteria and other micro-organisms.

Filtrine is also proud of its reputation around the world as a problem solver in the cooling of liquids. Prior to the advent of electric refrigeration, Filtrine filters and ice coolers were installed around the country for both drinking water and process water applications. In 1925 we designed and built one of the first electric coolers and introduced the storage-type cooling tank still featured on all Filtrine chillers. This coil-in-tank evaporator proved to be virtually freeze-proof, a feature which appealed to major compressor manufacturers such as Carrier, York and Frigidaire who began specifying Filtrine cooling tanks with their condensing units.

During the 1930's and 40's Filtrine entered the field of process cooling, developing the first packaged units for film processing and dough making. Working closely with the U.S. Army engineers during World War II we designed a batch-type ingredient water chiller for government bakeries. Taking advantage of our storage design, we produced a water chiller which, at the push of a button, could dump batches of constant temperature 34 degree water into a dough mixer without danger of freeze-up. These chillers provided quality control for most of the bread consumed by U.S. armed forces thorughout the world. Filtrine is now the leading supplier of bakery ingredient chillers.

Today, technology demands even closer control over heat removal and Filtrine continues to solve water chilling problems for government and industry. Whether the problem is chilling gasoline for testing new Ford engines, astronaut's space suits for NASA, or the NIKE Missile guidance system for Hughes Aircraft, Filtrine has provided the solution. Every day, Filtrine chillers and filters are being specified to solve these new and complex cooling and filtration problems.
