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