Internal training – differences ITV machines

Machines by type of ice ICE MAKING Ice is produced by freezing water. To freeze water, a thermodynamic process occurs extracting heat from the water, cooling down the water, until it freezes. To do such process, different components are used, all of them are known as the refrigeration system of an ice machine. The ice machines are cyclical when heat is used to harvest the ice, every cycle is the sum of freezing and harvesting (ice dropping from the evaporator). The ice machines are continuous when there is no change on the regime to harvest the ice, they freeze all the time. ITV ice...

Machines by type of ice Palette system: System that produces the ice using an horizontal evaporator, where the water is push upwards to the evaporator by a turbine and palettes. Cyclical machine. It does not use a water pump. SUPER STAR SUPER STAR+ Vertical system: System that produces the ice using a vertical evaporator. Used in the half and full dice ice. Cyclical machine.

Machines by type of ice Axial system (Ice Queen): System that produces the ice using a cylindrical evaporator, with an auger that scratchs the ice from the evaporator walls. It generates a granular ice, dry on the 50 and 85 versions (undercounter), humid in the rest. It is a continuous machine. It does not use a water pump. ICE QUEEN Axial system (Scala): System that produces an ice using a cylindrical evaporador, an auger takes off the ice from the evaporator wllas. The ice is dry, thin, flake type, and subcooled. Continuous machine. It uses a water pump. SCALA

Refrigeration system The refrigeration system, in charge of cooling down the water until becomes ice, it has the next principal elements: Expansion system

Compressor and condeser Compressor and condenser ✓ The condenser and the compressor are elements from the refrigeration system of the ice machines. Their function is to allow the machine to generate cold to form the ice and to produce heat to help harvesting the ice cubes. The compressor compress the refrigerant gas that has the heat extracted from the water, to transfer that heat to the ambient using the condenser. ✓ In the granular ice machines (IQ) and the flake ice units (Scala), there is no need on producing heat to harvest the ice. Those are continuous machines, ice is formed in the...

Water condenser ✓ Water is used to refrigerate. ✓ The machines condensed using water have a high water consumption, they need water to make the ice and to refrigerate the condenser. ✓ Sometimes it has a fan to help with the refrigeration. Air condenser ✓ Air is used to refrigerate. ✓ The water consumption in the air condensed units is much lower, it only need water to make the ice. ✓ It always have a fan.

Remote condenser Remote condenser ✓ Sometimes the machines do not have a condenser, those are remote units, and the condenser is out of the unit, is installed separately from the machine. ✓ It will be always air condensed. ✓ A refrigeration installation need to be done (piping, valves, …) to connect the machine and the remote condenser. ✓ The models are the RC manufactured at ITV (Remote Condenser). The condenser is purchased from an outside supplier and the condenser is assembled and finished in the factory with a chassis.

Condensing unit Condensing unit (U/C): ✓ It is a part of the machine, includes the condenser, compressor, and some other elements (valves, piping, pressure switches, etc.). ✓ According to the condenser that they have, it can be water or air condensing units.

Remote condensing unit Remote condensing unit (U/C): ✓ In ice makers generator or Split units, the condensing unit is not in the machine, they do not have a compressor or a condenser. ✓ The client can buy a remote condensing unit or not, depending on the installation of the units. That is explained in the Ice makers generators or split ✓ A refrigeration installation needs to be done (piping, insulation, valves, etc.) to connect the ice machine and the remote U/C.

Evaporator The evaporator is where the ice is formed, through the irrigation of water on its surface. Depending on the unit we have the next types of evaporators: ▪ HORIZONTAL: Ice cube units, with the type of ices Alfa, Gala, Delta, Super Star, Super Star Plus. VERTICAL: Evaporator for half and full dice ice, Spika units. FINGER TYPE: Quasar evaporator, with a ‘central hole’. AÑADIR FOTO EVAPORADOR TUBULAR: Evaporator for the granular ice of the Ice Queen and the flake ice from the Scala.

Compact vs remote unit Compact machines: ✓ In these units, the condensing unit (compressor and condenser) are integrated inside the machine, being a part of it. The condenser can be air or water. ✓ When the unit has an air condenser, it is indicated in the machine name with an A (air). ✓ When the unit has a water condenser, it is indicated in the machine name with a W (water). Remote machines: ✓ These machines do not include the condenser, it is apart. They do have the compressor inside. ✓ To function properly, these machines need a remote condenser, therefore an order of a remote machine...

Ice maker generator or Split Ice maker generator or Split: ✓ These units do not have the condensing unit, it comes apart. They do not have the compressor and the condenser. ✓ These machines usually are installed in places with poor ventilation or to avoid the noise generated by the condenser and compressor. It also allows to prevent the hot air inside the local. ✓ By not having a condenser and a compressor, they are more light than the compact and remote ones. ✓ There are two installation possibilities: 1. Machines connected to a cold generation station ➢ Sold without the remote U/C. 2....

COMPACTA REMOTE REMOTE SCALA U/C SPLIT without cold generation station SPLIT with cold generation station

Compact SCALA: ✓ A Scala machine with a condensing unit integrated inside the machine (compressor and condenser), all in the same base. Split SCALA ✓ It is a Scala ice maker, without the condensing unit. Split CO2 SCALA ✓ Like the above but using CO2 as refrigerant. Condensing unit not included. Keep in mind ITV does not seel CO2 condensing units.
