1.2.  Description 

 

The  ICE  TECH  PS  ice  cube  maker  is  the  result

development of a high technology factory.

 

Main Features: 

  Storage bin made of plyester strengthened with glas fibre or ABS

  Stock bin made of high resistance plastic materials

  Polyurethane insulation injected 

  Heavy duty door (pat.) except 22

  Agitator motor for continuous service

  Tough cam motor (50 Kg/cm)

  Safety device and clutch for the water pan preventing its breakage during the upward cycle, 

(pat.) 

  Machine stoppage and water pan protection dur

  The stock ice is the maximum than it could be thanks to the stop machine system.

  Low noise 

  High pressure safety pressostats even in air

  Large  condensers  (work  well  at  high  ambient  temperatures  and  reduce  cooli

consumption in water-cooled machines)

  Clear cubes 

  Ice Cube size can be adjusted (height and diameter).

  Easy to maintain and repair.

1.3.  Operating principle 

 

When the machine is switched on the compressor and the agitator motor start, the water entry 

valve  opens  and  allows  water  into  the  production  pan  up  to  a  level  where  the  float  makes  a 

micro-switch cut the current to the valve and so stop water entering the tray. The compressor, 

controlled by  capillaries  produces  enough  cold  in  the evaporator  to  gr

around its “fingers”. 

When the ice so formed reaches the proper size the paddles of the agitator are stopped and its 

motor suspended, works the end of cycle micro

starts the cam motor. When the micro

The  ICE  TECH  PS  ice  cube  maker  is  the  result  of  years  of  experience  in  this  field  and  the 

development of a high technology factory. 

Storage bin made of plyester strengthened with glas fibre or ABS 

Stock bin made of high resistance plastic materials 

Polyurethane insulation injected “IN SITU” 

Heavy duty door (pat.) except 22-32. 

Agitator motor for continuous service 

Tough cam motor (50 Kg/cm) 

Safety device and clutch for the water pan preventing its breakage during the upward cycle, 

Machine stoppage and water pan protection during the downward cycle, (pat.)
