The air conditioning unit model MINI performs the precision ai-conditioning inside small testing rooms and laboratories maintaining constant temperature and humidity values and assuring the uniformity in every point of the laboratory

The climatic unit type MINI guarantees the proper carrying out of the ISO / IEC 17025 laboratory activities and accreditation in the various application fields and it is considered suitable for samples conditioning and testing according to reference standard.

Type MINI assures constant climatic conditions, thus the reliability and the reproducibility of tests on samples.

  • Temperature: 23 1C;
  • Relative humidity: (45 50) 2 %;


  • Temperature: (20 21) 1C;
  • Relative humidity: 65 2 %;

The unit Type MINI is designed for special applications as e.g. precision weighing scales or testings that demand for normal atmosphere.

On request the supply of an isolated cabin combined together with the unit.

Air climatic unit Type MINI is divided in two parts:

  • Indoor unit, for air flow distribution into the conditioned room;
  • Outdoor unit, where are installed the electrical circuit, refrigerant circuit and HMI user interface;

Air flow distribution enters the air tangential to the walls at a low speed, less than 0,15 m/s, reducing the convective air movements and Coanda effect under the ceiling.

The User interface is on the front panel of the outdoor unit and equipped with a user-friendly Touch screen to input SetPoints ​​and other parameters, real-time monitoring of temperature and relative humidity.

Humidity is control by evaporative basin with humidification elements, principle focused on adiabatic saturation that used to regulate the dew point temperature with excellent performances.

The water charge to humidification is fed at 0F across the osmosis group for water handling.

Air climatic unit type MINI is compatible with international communication protocols and communicates through USB or ETHERNET slots. The operator can connect by remote and download collected data through a PC-software on request.
