The samples have to be controlled at constant thermo-hygrometric conditions according to national and international Standards for several application fields, ideal for Textile according to the Standard ISO 139.
A huge amount of laboratory analyses require uniform and stable conditions of Temperature (°C) and Relative humidity (%) for sample preconditioning and further physico-mechanical tests on materials.
The factors that could influence tests are:
Specific laboratory tests require a "Standard Atmosphere" in order to get reliable, repeatable results on samples in Textile QClaboratories and other quality control on different materials.
Solutions for sample conditioning are often very rudimentary and engineers are still trying to do researches on technical advancements necessary for get more precise test performances to bypass objective issues.
The conditioning chamber Standard Atmosphere is composed of an insulated body structure ideal for Textile personally studied and designed from STA Branca Idealair for Textile Labs and other laboratories that has to manage the preparation of sample to test analyses.
The chassis of Standard Atmosphere hosts a huge amount of samples and allows to install more shelves and other special sustainable supports.
The Standard Atmosphere helps the interaction by the operator thanks to the 5" HMI Touch Screen setting up PID Close-control, monitoring variables and I/O alarms diagnostics, all in accordance with IEC Standards.
Here below are described climatic ranges:
|TEMPERATURE (°C)||± 1°C||20°C||27°C||23°C|
|RELATIVE HUMIDITY (%)||± 2%||65%||65%||50%|
The conditioning cell is made of stainless steel metal structure with 60 mm of injected polyurethane foam, while the front door knobs allows the user to get a comfortable access to internal spaces.
Active safeties in presence of alarms to avoid any risks to the operator in accordance to the Safety Standards.
The refrigerant circuit is equipped with SCROLL compressors and an condensation cooling heat exchange all-in-one to allow refrigerant condensation indoors with critical temperatures up to 38°C and integrated cooling evaporator on the structure.
Temperature and Relative humidity PID control works out measurement of variable with resolutions up to ± 0,01 °C and ± 0,01 %.
Humidification systems supplied by an auxiliary water tank charged with demineralized water at 0°F previously treated by a reverse osmosis circuit for water purification.
