Review on Efficient Temperature Control Solution: Beverage Air 502-289B for Optimal Beverage Preservation by Ken Reiff

This temperature controller appears to be an OEM part and has the Beverage Air part number on the label (too often parts on Revain are misrepresented as non-OEMs) . The handle shown in the photo is not included. This is a problem when replacing an old Cutler-Hammer 502-195A control system with this Ranco type control system. The old pen doesn't work. You will also need a Beverage Air 502-295B pen. Luckily I kept some extra parts from the more "universal" replacement parts and had a Ranco pen that I didn't throw away. additional details I saved from previous work didn't fit either. So I lowered the rating to 3. The controls fit, it works but now I have to buy a handle that should have been included separately.
