La CACTUS é un economizzatore d’acqua a circuito chiuso vaso aperto, studiata e realizzata per raffreddare, recuperare e riutilizzare l’acqua di condensazione in uscita dai gruppi frigo.

E’ in grado di ridurre a ZERO il COSTO dell’ACQUA in tutti i laboratori alimentari.

La linea cactus è composta da 3 famiglie di prodotto:

Inverter

From the model 25 up, the Cactus is equipped with inverter.

The inverter is an electronic device which, by increasing or decreasing the rotation speed of the compressor, the fan and the pump, allows the modulation of the power supplied by the machine in a way that is proportional to the actual demand.

Advantages:

  • decrease in electricity consumption of 40% minimum.

Disadvantages:

  • higher cost of the components (pump, fan and compressor to which it is applied)

Free cooling

The free cooling is a cooling system that uses only the difference of temperature with the outside environment (enthalpy).

The free cooling is used on thermal systems or on part of them and it exploits the air at room temperature to cool any element (liquid, gaseous or solid) without the use of refrigeration machines (such as the compressor).

An example of practical use is that of a hot fluid (having a temperature higher than that of the surrounding environment’s air) which is cooled by means of a finned battery placed outside a building.
At its passage, the fluid will transfer heat to the air with the subsequent cooling of itself, without any use of compressors and refrigerant fluids. The best known example of “free cooling” is the car’s radiator which exploits the air to lower the temperature of the engine cooling water.

Advantages

  • None or little maintenance, generally linked to the radiator cleaning;
  • Simple technology, use of outside air to cool;
  • Very low energy consumption, it requires no energy to operate

Disadvantages

  • Effectiveness linked to the environmental conditions.

Cactus functioning

The heart of the machine is the compressor.

In the compressor the gas (R410) is compressed and it moves to the battery (the gas flows through the copper pipes) which is designed and made-to-measure.

The hot and high pressure gas is cooled in the battery (the fan regulates the condensation, also called liquefaction, that is the transition of a substance from the gaseous state to the liquid state).

The condensed gas, in a liquid state, passes through a filter that retains the damp (there is also a round little glass which is the liquid indicator to see the gas and to see if there is a lack of it. In this case, the gas will appear frothy).

After passing through the little glass, the gas comes to the expansion valve, which reduces the pressure to bring it to the one necessary for the realization of the next phase, the evaporation (where the gas returns from the liquid state to the gaseous state).

Evaporation takes place inside the plate, with a “spray” effect : the R410 from liquid becomes vapour, which is to say it vaporizes (it changes of state) and so it subtracts energy (the water is warm and is cooled here. The heat -energy- is removed from water). Both the gas and the water flow through the plate, each one in an appropriate duct.

So, the water is cooled and it goes in the system’s circuit of the production process.

And what about the gas? After the plate, the gas is aspirated by the compressor to restart the cooling cycle.
