Grindmaster Corporation 3342 Freezer
Remote Beverage 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:
– standard single barrel remote unit
– standard twin barrel remote unit
3341A – single barrel remote unit with internal autofill system
– dual barrel remote unit with internal autofill system
