This is a Jet Spray juice dispenser and chiller.  These units are found in restaurants for various juice products.  This particular unit had two containers.  As can be seen I installed a bulkhead between the two sides to allow for one holding area.  I installed the inlet in one side and the outlet in the other as can be seen in the upper left corner of Picture 2.  The front contains three switches, one which turns the chiller on and off.  The other two switches turn on magnetic stirrers which are not currently installed.

The silver hump in the bottom back of the tank is the actual chill unit.  This hump becomes cold when the unit is turned on.  This unit is fairly large and would not be recommended unless you have a spare room.  As can be seen in these photos this unit is under the stairs into the basement.  The tank is on the other side of the wall.

I currently run this only in the summer with a timer.  It runs for about 2 hours on two occasions during the lights on time period.

This is a model TJ-3 from Jet Spray, Inc.  It is rated at 1/5 HP, 120 Volt, 5.0 Amps.  Unfortunately it is R-12 Freon so any repairs could be come cost prohibitive.  I was given this unit from storage of my fathers restaurant.  I have seen these types of units advertised in restaurant auctions and you may be able to pick one up cheaply.  In my contacts with Jet Spray I found that these units run $800-$900 new and most of the spare parts are available.
