Tenders Description & Specification for Advanced Climatic Cabinets
Advanced Climatic Cabinets
These Advanced Climatic Cabinets have been designed to be user-friendly, intuitive and above all highly accurate.
Version with temperature and humidity control is capable of generating 95% humidity with accuracy and reliability, making it also a perfect solution for cement specimen curing
Fitted with a new and improved thermoregulator, the intuitive interface features a 7” touchscreen color display that makes it easy to programme freezing and thawing cycles.
All models can record temperature, humidity (when applicable) and time measurements in full compliance with all the relevant Standards.
Cabinet
The cooling system and control unit are in the top of the cabinet for easy inspection and maintenance.
Insulation with high density (42 kg/m3) polyurethane 90mm thick is CFC free and reduces heat loss by 30% compared to similar having 60 mm thickness.
Constructed from monobloc stainless steel, the cabinet has four shelves supported on stainless steel guides capable of holding heavy specimens. All internal angles have been rounded for easy cleaning.
Thermostatic unit
Air circulation is ensured by two fans for optimum uniformity conditions in the chamber. The de-humidification is controlled by a smooth tube evaporator, while the humidity control is based on pressure steam boiler and ensures humidity values above 95% to saturation. Cooling is obtained by direct evaporation of CFC free refrigerant gas by evaporator, while heating is achieved by resistances.
Control unit
Easy programming of the thermal cycles (edit and perform of thermal cycles), even with delayed test start
Data acquisition and recording of humidity, temperature and times values at sampling rate of 1 samples/minute.
The front panel includes a large colour 7” touch screen display allowing:
Manual control of the cabinet (setpoints, temperature rate, etc.)
Simultaneous display of set points and absolute output values, both in numerical and graphical format.
All models allow easy data export, through industrial USB port, on the internal 512 MBytes memory including temperature and humidity values and implemented thermal cycles.
Humidity sensor
Allows measurements of humidity up to RH 100%
Temperature sensor
Two channels for PT100 temperature sensors (included) one movable inside the cabinet area (or positioned in the sample) and one fixed measuring chamber temperature.
Two additional PT 100 sensors can be added on request.
