Precision air conditioning units - Branca Idealair


Branca Idealair Climatic units are precision conditioning systems designed for TESTING LABORATORIES and METROLOGICAL ROOMS

Known as Branca Idealair climatic units, the precision air conditioning units - Branca Idealair allow reaching and maintain stable climatic conditions, thus the Normal Atmosphere, in compliance with national and international Standard as UNI EN ISO 1:2016, ISO 139:2011, ASTM D 1776-20, ISO 187:1990, TAPPI T402, UNI EN ISO 2231, ISO 2419, OIML G13, ISO 23953, IEC 60068-3-5, ISO/IEC 17025, ASTM D1909, EN12341:2014, M&S Standard conditioning, PGA, EDANA, BISFA Standards, OIML etc. etc.

The Climatic Elements are made with advanced technologies and components, the best on the refrigeration market and ideal for precision air conditioning performance.

The refrigerating circuit of a Climatic unit is charged with fourth generation refrigerants, known as HFO refrigerants, Freon gases compatible for a sustainable Ecological future in the refrigeration and precision air conditioning applications.

Based on its performance, the Branca Idealair Climatic Element guarantees constant regulation within the tolerance thresholds required for both temperature and relative humidity.

Getting a special approach to every single project development with an in-depth synergy with customers by our technical team and looking after all installation aspects and technical sketch drawings for testing laboratories, Branca Idealair follows up all project design and specification keeping always in consideration the importance of using proper insulated walls and thermal absorbent ceiling.

Branca Idealair is able to give you the best quality consultancy for laboratory projects and applications.


The realization of a testing laboratory including precision air conditioning allows achieving a fundamental advantage, when, in terms of Quality Management, are improved firstly all laboratory constructive features as e.g. the use of quality construction materials, professional thermal sealants, steam resistance materials, thermal transmittance and many other aspects that ensure the precision close control of temperature and relative humidity, thus their stability within very close tolerances.

Nowadays and after many years of experience spent in testing laboratories supplies and project designs, Branca Idealair is considered company top leader in precision air conditioning and testing laboratories applications as company qualified in design and construction of testing laboratories and CMM controlled rooms for Dimensional Metrology.


For geometrical measurements in Dimensional Metrology, the Temperature is a fundamental element as reported by the International Standard ISO 1 that sets it at 20 C as reference temperature for geometrical parts.


An unstable temperature from the reference temperature put the laboratory operator in the condition to apply an offset to final measurements, contributing then the increase of total measurement uncertainty.

Then they have to be fixed consequently acceptable limits for temperature variations as a constant validation for laboratory tests execution, in order to determine how temperature can have fluctuations from 20 C during test performances without penalizing results in terms of uncertainty.

Branca Idealair supplies precision air conditioning units and solutions known as climatic units - Branca Idealair suitable for every laboratory's applications and where is a need for constant thermo-hygrometric conditions and ideal for a wide range of environment air volumes (m3) and able to assure to the Customer the achievement of a quality accreditation for their laboratory, certificates released by Standard Organizations across a sustainable and fully-functional air conditioning system; just click here below:


Customers by Branca Idealair are ready to get benefits from our climatic units with the last new technologies implemented:

Branca Idealair Climatic units can be direct expansion units or with cooled-water circuits combined with hydronic modules (chillers) and charged with eco sustainable refrigerants R1234ZE and recirculation water pumps chosen according to the installation project and capacity eco-refrigerant
High level performances in close-control modulation optimized on thermo-hygrometric variables especially improved on R.H. control (%) thanks to the introduction of 1 level temperature as first stage of the close-control temperature-close-control
User-friendly interface with 7" HMI Touch Screen allows the users to monitor digital reading of climatic values on real time and of those settings able to guarantee the precise control of thermo-hydrometric conditions entering easily in the P.I.D. programming areas and thresholds settings as digital and analogue outputs monitor-trend-grafici
Integrated trend graphs monitor collecting data on a memory SD-HC 64 GB card included the (.CSV) file export function to the PC or SERVER folders monitor-trend-grafici
Ethernet slots on the front panel for the remote control with Web server unit and remote support, powered by CORVINA CLOUD networking
Weekly ECO-programmer to set the unit operation in NORMAL or ECO mode, e.g. in the weekends and night hours; eco
AUX I/O for logic signal outputs for external surveys or utilizers (switching On/Off by remote, Set point changes, etc.) output-comuni
Log-IN function with different authorization level access (e.g. Lab responsible, User, technician, programmer, etc.) log-in-function
