These are the kind of cooling coils used in larger multi-evaporator walk-in coolers.  A prime example is the walk-ins used in convenience stores.  They typically have two or three multi-fan evaps connected to a single outside condensing unit for cooling their milk, bottled water, and pop (soda for you southerners). Both Larkin and Bohn are owned by Heatcraft which means the product lines are identical and so is most of my verbiage.

Walk-in coolers can get literally as large as a house.  Wholesale suppliers of produce or frozen foods may have need for something of this size and the coil shown at the right could be used for this type of application.

Freezer cooling coils look identical to the ones above, however with the addition of defrost heaters and drain pan heaters they can survive and function quite nicely at sub-zero temperatures.

All coil models feature easy access side panels with refrigeration piping on one side and electrical hook-up on the other.  Smooth white prepainted cabinet for a long lasting clean appearance.  They also have internally enhanced refrigeration tubing to create turbulence and enhance heat transfer.  Each supplied with a take-apart drain fitting for easy removal of drain pan for service if required.
