We highly recommend this coil for your keg cooler, only purchase it with the defrost heaters and a littler extra horsepower, now run your cooler at 25F or so, talk about the coldest beer in town.

This style of cooling coil mounts dead center in the middle of the walk-in cooler/freezer and of course is firmly affixed to the ceiling of a restaurant walk-in.  The idea is to create a little extra space along the walls so you can stack you product higher on the perimeter and store more stuff.  It is also very good at distributing the cool air evenly throughout the inside of the cooler so that the eggs on one wall are the same chilly temp as the veggies on the other wall.  This coil also seems to be less annoying when installed in one of the taller walk-ins (7'7"ID or higher) then your people won't continually bump their head, followed by a scream and finally they end up throwing things. Ouch!!

Air enters thru the fans and exits thru the finned coil (black area) on each side for even cooling.

This is identical in appearance to the coils listed above but with the addition of electric defrost and drain pan heaters for applications below freezing.  They mount in the center of the ceiling of a walk-in freezer providing excellent temperature control and allowing extra space for storage along each wall.
