Ecolab Introduces the Next Generation Oasis® Dispensing System

ST. PAUL, Minn., May 20, 2002 -Continuing its global leadership in new product development, Ecolab has taken the Oasis cleaning system to the next level by introducing the new Oasis® Select 4™ Dilution System. The new system includes four new products: a fabric odor eliminator, a heavy-duty alkaline bathroom cleaner, and two new odor counteractants.

For more than 10 years, foodservice, healthcare and hospitality operators have trusted Ecolab's Oasis® Cleaning System because it delivers sparkling results at the lowest possible cost, and also provides them with a centralized location for storing, diluting and dispensing premium cleaners.

The Oasis® Select 4™ system is the complete cleaning system, offering cleaning products for floor, bathroom, glass, carpet and exterior plus sanitizers, air fresheners, and all-purpose cleaners. New products added to the system include Oasis 270 Up N' Away Fabric Odor Eliminator, which is a heavy-duty institutional fabric odor neutralizer that safely absorbs odors on clothing, carpets, curtains, rugs, and other fabrics.

Also new is Oasis 302 Heavy-Duty Alkaline Bathroom Cleaner, which is a daily cleaner for areas that have soft to medium water hardness and require an alkaline instead of an acid cleaner. Two new fragrances were added to the odor counteractants product line, Oasis 272 Juniper Splash and Oasis 274 Ocean Waves, to offer more fresh and clean fragrances for counteracting malodors in rooms.

"The Oasis® Select 4™ Dispensing System provides our customers the improvements they have asked for-a multiple product dispenser, greater reliability and durability, and minimal space needed for installation," says Randy Lia, marketing manager, Housekeeping, Ecolab. " Of course, the system continues to provide our customers with outstanding product performance and the service they expect."

The Oasis® Select 4™ Dilution System is a smaller, more durable wall-mount dilution system compared to the original dispenser. Operators can now connect up to four Oasis products to a dispenser instead of one product. These design improvements offer operators greater flexibility without sacrificing the performance they have come to depend on. The new dispenser also includes a drip tray so that operators can direct product overflow to a drain.

Designed to work with both spray bottles and mop buckets, this system quickly and accurately delivers the proper dilution of product every time, so there is no manual mixing of chemicals. Operators simply choose from more than 30 Oasis products to create a customized system that meets their unique cleaning and sanitation needs.

Oasis concentrated products, which are available in 2.5-gallon and 15-gallon containers, along with the other system components, will continue to feature color-coded labels with language-free pictorials to further simplify training and reduce misuse.
