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.
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. 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.
All models can record temperature, humidity (when applicable) and time measurements in full compliance with all the relevant Standards.
Cabinet
Constructed from monobloc stainless steel, the cabinet has four shelves supported on stainless steel guides capable of holding heavy specimens. The cooling system and control unit are in the top of the cabinet for easy inspection and maintenance. All internal angles have been rounded for easy cleaning.
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.
Control unit
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.
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.
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.
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.
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.
Humidity sensor
Allows measurements of humidity up to RH 100%
Main Features
Energy efficient — Heat loss is reduced by 30% thanks to a high density polyurethane insulation (42 kg/m3), CFC-free and 90mm thick (instead of the usual 60 mm).
Flexible — up to three movable temperature sensors (two optional) can be positioned inside the cabinet or placed in the sample to meet Standards’ requirements. One fixed also included as standard.
High performing — Advanced controller with storage of 100 temperature and humidity cycle programs, each one with up to 64 segments.
High accuracy — ±1°C, ±5%RH.
Standards compliant — temperature, humidity and time are all recorded in accordance with Standards.
Intuitive interface — with a large and easy-to-use 7” color touchscreen display.
