(Sept. 21) Malvern, Pa.-based PuriCore PLC, maker of Sterilox biocide generators, has expanded its sales and marketing staff with the addition of regional sales director Tom Happ and senior marketing manager Geoff Koontz.

Happ, who previously was director of sales for Edison, N.J.-based Exhibit Group Inc., will be responsible for the northeast and southwest U.S.

Koontz spent the past two years as business development manager for AgroFresh Inc., the Spring House, Pa.-based maker of SmartFresh post-harvest treatment.

Senior vice president Tom Daniel said it was necessary to create the new positions to meet growing demand.

“We’re several hundred percent ahead of last year because of the adoption of the technology, and the benefits are being realized in the food retail community,” said Daniel, who previously worked with Happ at Syosset, N.Y.-based Baker’s Aid Inc. and Wilder, Ky.-based Display Specialties Inc. “It’s starting to really take off.”

PuriCore announced Sept. 14 that it had agreed to a $3.3 million contract with a U.S. retail grocery chain to install more than 200 of its food-safety systems. Daniel declined to name the retailer but said it was the second-largest contract in the division’s four-year history and will raise the number of its systems installed in U.S. grocery stores to more than 1,400.

Daniel said he expected the new systems to be installed by the end of the year.

Sterilox converts salt and water into hypochlorous acid, which is used to wash and sterilize fresh produce and equipment, killing pathogens and organisms that cause spoilage. The product can be used in crisping or misting as well as in floral and seafood.

Daniel said the result is enhanced freshness, reduced shrink and safer products.

PuriCore started 10 years ago in the medical and dental fields before expanding into food safety four years ago. The company, which has more than 2,100 installations worldwide, reported revenues of $12.8 million and expenses of $12.4 million in 2005.
