Branca MINI Climatic unit is designed for laboratory air conditioning, suitable both for controlled room temperature and humidity within established tolerance limits


Climatic unit type MINI is able to reach and maintain constant the ambient temperature and humidity under the closest tolerance limits.

The microclimate control conditions at Standard Atmosphere parameters allow laboratories to carry out lab tests in compliance with ISO/IEC 17025 general requirements that express testing methods and activities for Laboratory accreditation process, applied to various laboratories and it describes the preparation of samples to tests and subjected to a conditioning period at Standard Testing Atmosphere.

The climatic unit Type MINI is a precise close-control conditioning unit allows to give the suitable Standard Atmosphere climatic conditions requested to carry out tests and to get repeatable and reproducible test results.

Temperature: 1827 1C;
Relative humidity: (45 65) 2 %;

The climatic unit Type MINI is designed for special testing applications as weighing scales measuring or physical laboratory tests that demand Standard Testing Atmosphere. This is an advantage for final installation.
There is no need to install external unit outside the building.

project-questionnaire Our company can manage the follow-up the project design of the cabin according to the request.
Send us technical data of the cabin.

The Climatic unit Type MINI is composed of two modules:

where are installed the electrical circuit, refrigerant circuit and HMI user interface;

for air flow distribution into the conditioned room;


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.

Relative humidity is controlled by a humidification elements that warm up water in condensate recovery basin.
The operation principle is based on adiabatic saturation effect that permits the unit to modulate the dew point temperature control with an excellent performance.

The water charging to condesate recovery basin is done by a pump that charges water at 0F treated by an reverse osmosis circuit to avoid the presence of lime scale.

All data can be viewed on a building automation template, because the logic programmable unit is compatible with internation IEC communication protocols through serial or TCP-IP connections.
The trend graphs and records can be easily downloaded.
