Free and Force Convection Apparatus Manufacturer,Supplier and Exporter in India

Free and Force Convection Apparatus

Product Code : EL-HAMTLE-10761

The Apparatus offers basic experiments for targeted teaching on the topic of free and forced convection on various heating elements. 
At the heart of the experimental unit is a vertical air duct into which various heating elements are inserted. 
An axial fan is located on top of the air duct. 
The fan draws in ambient air and guides it through the air duct. 
The air flows past a heating element and absorbs heat. 
Four heating elements with different geometries are available to be selected. 
In order to investigate free convection, two of the four heating elements can be operated outside of the air duct. 
The heating elements are designed in such a way to release heat only at their surface. 
The compact design ensures rapid heating and a short time for experiments.
The experimental unit is equipped with temperature sensors at the inlet and outlet of the air duct. 
The air velocity is measured to determine the airflow rate. 
The microprocessor-based instrumentation is well protected in the housing. 
The software consists of a software for system operation and for data acquisition and an educational software is connected to the PC via USB.
Heating power and flow rate are adjusted and displayed via the software.
