1. What is a MACS Cooler?
MACS stands for Modular Automated Cooling System. It provides forced-air precooling of palletized product in the same way as tarped forced-air precooling tunnels (often called “pressure cooling” tunnels) only with many advantages.
2. How is it “Automated”?
After the pallets are placed on the infeed conveyor, they are automatically conveyed through the cooling zones in steps and when the final pulp temperature is reached, are transferred to an outfeed conveyor inside of a refrigerated building. The cooling time spent in each zone is automatically computed from a pre-programmed recipe that can be customer configured based on product type and packaging. Sensors constantly detect temperatures and pressures to keep the cooling process on track.
Any products that can be cooled on a conventional forced-air tunnel can be cooled better and more economically on a MACS Cooler! Ideally, it would cool field packed-palletized cartons on 40” wide x 48” long pallets with load heights ranging from 54” to 83” for the “standard” MACS and 69” to 98” for the “tall load” MACS. Unusual load configurations can also be accommodated.
|Produce Commodities That Are Regularly (Or Can Be) Forced-Air Cooled|
Note: Any commodity that can be forced-air cooled on a conventional tunnel can be precooled better and more economically on a MACS Cooler.
4. Are MACS Coolers expensive?
When considering the cost of the refrigerated building space required for conventional tunnels along with the equipment itself, MACS Coolers are actually less expensive to start out and continue to save operating costs every season.
5. How are MACS Coolers delivered?
MACS Cooler modules and their components are built off-site and then transported to the location where they will be installed.
