New York Hutterite Colony, February 2020

The case

In a Hutterite Colony in New York, Southern Alberta, black mould contamination was happening in a walk-in cooler.

The Problem

Aspergillus Niger (black mould) spores were reproducing at a high rate, which required a complete washdown and sterilization of
the cooler every week, to prevent individual health issues. Mould would form on the shelves and the necks of the preservative jars.

      Hutterite Colony Walk-In Cooler Coil                                                       Sanuvox Installation at Hutterite Colony

Sanuvox Customized Solution

The cooling unit was cleaned by a refrigeration technician and a Sanuvox IL40-G was installed to destroy the spores early July 2017.

Conclusion

There has not been any reoccurrence of mould in the cooler. Two months after install, the Colony bought two crates of pears, same harvest and variety. They stored the crates in two different walk-in coolers. The pears in the cooler without Sanuvox UV treatment started turning brown and rot within 5 days.

The pears in the cooler with Sanuvox UV showed no signs of degrade. The increase of shelf life of produce impressed the Colony and since then, they equipped the 2nd cooler, along with a root vegetable cold storage room. The Colony is very pleased with the Sanuvox equipment and appreciate having clean cooler with food that is not contaminated with black mould.

Food Distribution Center, June 2018

The case

Controlling odors in the onion storage room at a food distribution center for a national grocery store chain.

The Problem

To prevent onion odors from contaminating fruits and vegetables stored in adjoining rooms, the onion storage room is kept at a negative pressure using a 3,000 cfm exhaust fans. The customer had two main objectives: 

1.To control the onion odors 

2.To reduce the amount of exhaust air to lower the associated cost of conditioning makeup air

Sanuvox Customized Solution

Sanuvox provided two IL30-X units that were installed upstream of the cooling coil in a 27,000 cfm air handler to photo-oxidize the onion odors.

Conclusion

Onion odors were dramatically reduced, and exhaust air lowered by 40% to 1,800 cfm. Energy savings from the reduction in exhaust air is equivalent to 3 tons of cooling.
