FREEZER APPLICATION AND SPECIFICATIONS

Remote Freezers

The freezer consists of a freezing cylinder with a rotating internal auger (dasher) that is belt-driven by an electric motor. The auger scrapes frozen product off of the inside of the refrigerated cylinder.

Crathco remote beverage freezers are designed to operate in conjunction with a remote condensing unit or be connected to a central refrigeration system. It is recommended that the condensing unit have no more than 2 1/2 hp per barrel to ensure maximum efficiency. The refrigerant must be R404A (Dupont®HP62®). The refrigeration for each barrel is controlled by the liquid feed solenoid. The liquid feed solenoid is opened and closed by the limit switch attached to the drive motor. (When the product consistency reaches the desired point, the switch closes and de-energizes the liquid feed solenoid 20 seconds later.) Twin units operate with each barrel independently. Quick connect refrigeration connections are supplied with each unit. Each freezer is factory supplied with 5/8" suction and 3/8" liquid connections. The piping connecting the freezer with the remote condensing unit or central system should be sized according to industry standards. The installer is responsible for sizing the refrigeration lines to the unit. When properly operated and cared for, the remote freezers will provide many years of service. Proper care includes regular cleaning and maintenance. To minimize the amount of maintenance necessary, follow the operating proce- dures outlined in this manual.

There are four variations of the remote unit: 3341 – standard single barrel remote unit 3342 – standard twin barrel remote unit

3341A – single barrel remote unit with internal autofill system 3352 – dual barrel remote unit with internal autofill system
