Description

The BET 012 is part of a series of units enabling experiments to be performed on different heat exchanger types. In conjunction with the BET 011 supply unit, which has a hot and cold water circuit and all of the necessary connections, the experimental unit is ideally suited for investigating the functioning and behaviour of a tubular heat exchanger in operation.
The BET 012 is connected to the BET 011 using quick-release couplings. Hot water flows continuously through the inner tube and cold water through the outer tube. Part of the thermal energy of the hot water is transferred to the cold water. Valves on the supply unit are used to adjust the flow rates of hot and cold water. The supply hose can be reconnected using quick-release couplings, allowing the flow direction to be reversed. This allows parallel flow and counterflow operation. Temperature sensors for measuring the inlet and outlet temperatures are located at the supply connections on the BET 011. The robust design of this device makes it suitable for use in schools.
The equipment is set up on an steel coated frame. The frame is also equipped with adjustable feet with rubber to avoid vibrations. This gives it great strength and a flexibility of integration into your laboratory.
The manufacture of this equipment complies with the European standard for machinery manufacturing.
