In 1992, Jack Kertzman retired and Halma Holdings, the North American arm of London-based Halma plc, acquired Perma Pure.
HALMA HOLDINGS INC LICENSE
Perma Pure purchased the exclusive license from DuPont for the technology to manufacture tubing from Nafion™ polymer in 1978 and remains the sole manufacturer of Nafion™ tubing. While its extreme corrosion resistance was required for this application, Nafion™ polymer’s very selective permeation by water was a serendipitous development. Nafion™ polymer was developed as an improved material for electrolysis membranes in chlor-alkali production, where salt solutions are separated for production of chlorine and sodium hydroxide. Perma Pure was founded in 1972 by Jack Kertzman to provide tubing solutions for gas drying and humidifying applications. Perma Pure founder Jack Kertzman holding a tube made from Nafion™ polymer Nafion™ polymer is closely related to Teflon but has been chemically modified to make it function as an ion exchange membrane while still retaining the physical and corrosion resistance properties of Teflon. Scientific uses include exploitation of the electrochemical and ion exchange properties of Nafion™ polymer, as well as sample conditioning for laboratory analysis. Perma Pure offers complete systems to accomplish this sample preparation as well as individual components for incorporation into other conditioning systems. Stack gases must be conditioned to convert hot, wet and dirty gases into the cool, dry and clean samples required by analyzers. Industrial uses include gas sample conditioning for process monitoring or environmental compliance monitoring. Humidifiers raise the moisture content of dry respirator air to protect patients from dehydration. Removal of excess water prior to breath analysis protects analyzers and improves the accuracy and precision of analysis. Medical uses include the drying of breath for anesthesia monitoring, respirator monitoring, and metabolic testing, as well as humidification of respirator air or supplemental oxygen. We market these products worldwide for use in medical, industrial and scientific applications. Perma Pure LLC, a Halma company is a leading manufacturer of gas conditioning products including dryers, humidifiers, filters, coalescers, specialty scrubbers and complete sampling systems.
