How it Works
Alchemist combines the adiabatic cooling principle with refrigerant fluid subcooling to increase system efficiency. It is installed downstream of the condenser and/or gas cooler.
- Dry operation: external air is drawn in and conveyed onto the finned coils. The humidification process is deactivated, no water is present and the humidifier pack is dry.
The subcooling readings by temperature probes modulate fan speed to optimise power use. - Adiabatic operation: external air is drawn in and passed through the humidifier pack (protected inside the machine). The adiabatically cooled air (therefore at a lower temperature than the external air) is conveyed to the finned coils thus increasing the frigorific fluid subcooling. The subcooling readings by temperature probes modulate fan speed and adiabatic cycles to minimise power/water use.

Subcooling: Frequently Asked Questions and Expert Answers
Subcooling is the reduction of the temperature of the refrigerant leaving the condenser.
Read all FaqSubcooling results in an increase in the cooling capacity of the system, hence electrical savings and a higher COP (coefficient of performance).
Read all FaqAlchemist is a patented solution from MITA Cooling Technologies that combines the useful effect of subcooling with the natural and efficient operating principle of an adiabatic cooler in a single device.
Read all FaqA fan draws in a portion of air from the outside environment and then runs it through a finned coil inside which circulates the refrigerant to be subcooled.
Read all FaqAlchemist can be used with any type of refrigerant.
Read all FaqThe thermophysical characteristics of R744 make this refrigerant perfect for subcooling.
Read all FaqAn adiabatic gas cooler must adiabatically cool the entire air flow rate of the gas cooler itself, Alchemist works only on the subcooling air flow rate.
Read all FaqDownstream of a gas cooler in R744 systems, we have several references in commercial refrigeration, or combined with a refrigeration unit.
Read all FaqAlchemist is designed to bring efficiency to the system, which is why it does not require frequent or special maintenance operations.
Read all FaqAvailability of mains water and a discharge point, an electrical connection, and a junction between the Alchemist coil and the refrigerant line.
Read all FaqCertainly. The subcooler is an environmentally sustainable solution because it provides an efficiency "boost" with each installation (COP increase).

Environmental and economic sustainability of each MITA adiabatic subcooler
- Minimal use of water (only for adiabatic operation), useful for facilitating heat transfer (i.e., cooling of the process fluid).
- Optimized energy use (higher efficiency due to adiabatic supply).
- Falls within the product categories that MITA is able to regenerate.
- Indication of “carbon footprint” from the MITA team.
