This picture demonstrates the Thru-the-Wall Design of a Refrigeration System. A framed opening (like a window) is created in the wall and the System simply bolts into place.

From the inside, we can see the cooling side of the system. The built-in drain has a flex-tube extending to the outside of the building. This emphasizes the fact that Systems are very easy and inexpensive to install.

President Gene Stampfer stands in front of the largest model of Refrigeration Systems to date. McCain Foods is installing these KJ5000's at their company owned potato storages. The refrigeration system is installed so the cooled air is blowing into the air plenum, preferably prior to any humidification system. It is commonly understood in the potato industry, that blowing the cooled, humidified air up through the storage pile offers the greatest crop protection. This is also true for carrot pile storages.

Since these McCain Foods potatoes will become french-fries, they are stored at 42 degrees F, which is known to be the best temperature to store potatoes that will eventually be fried.

This angle view of the system helps demonstrate the through-the-wall design. You are looking at the inside of the System and the two "tabs" on the side of the machine are used to bolt the system into the wall opening. This particular design is well balanced, eliminating the cost of special supporting systems.

This is one of seven Refrigeration Systems currently in use by McCain Foods in various potato storages. This particular system is one of several located at a large McCain Foods storage facility in Florenceville, New Brunswick.

This is a 2 bin potato storage located in the Shelburne, Ontario area. There are two Model KJ1500,s, each servicing a separate Pile-Type storage area. The potato's are kept at 50 degrees F., and this especially critical during the warming spring and early summer months. The potatoes in this storage are used by Hostess/Frito-Lay for making potato chips. Systems are also effective for cooling other Pile-Types of storage such as carrots.

Here you see twin Refrigeration Systems, model KJL2500. They are located at a peach farm, where the peaches are loaded into large baskets placed on rolling racks, then brought into the cold-room...up to 60 tons at a time. The large evaporator fans effectively circulate the cold air throughout the baskets of peaches.

As the peaches enter the cold room, they have a field temperature of about 80 - 85 degrees F. The peaches are cooled to 36 degrees F. in approximately 10 hours (an effective cooling time for peaches). This preserves the freshness and extends the shelf life of the peaches until they reach the consumer. A cold-room such as this would be effective for other bin-stored crops, for example carrots.

Here we see a model KJL800 which is installed in a Cold Room at a nursery. The main purpose for this Cold Room is for the storage of "bare-root" plants.

Inside the Cold Room, you can see various "bare-root" plants being stored. "Bare-root" plant storage life is extended by utilizing a Refrigeration System. As the weather naturally warms, this nursery is able to continue to offer "bare-root" plants to their customers. This gives the nursery a competitive advantage over others in the area.

In this photo, we see a 2 bin potato storage in New Brunswick, Canada. The Systems, model KJ2500, keep the potatoes at a steady temperature of 42 degrees F. all the way into July. McCain Foods contracts/ buys these potatoes for french-fry production.

These are 2 KJL1500's on a bin-type carrot storage in the Holland Marsh north of Toronto. The carrots are cooled to 31 degrees F in the fall. This temperature of 31 degrees F is maintained through the spring and summer, as the ambient temperature rises to approximately 90 degrees F. The crop is kept in the best possible condition for sale to market.

Refrigeration Systems are built based on your cooling requirements. Here we see a building with two different size storage rooms, thus two different models of Systems; a KJL1500 and a KJL800. They are keeping carrots in bin-type storage at 31 degrees F. We build you the proper system.
