HL 530: Training Panel Function of Gas Heater

Print Ask to this Articlel

Training Panel Function of Gas Heater

Training Panel Function of Gas Heater

Product Details

Technical Description
The HL 530 is used to illustrate the functioning of a gas combination water heater. The main components of the gas water heater are clearly arranged on a panel to allow better understanding. A system diagram also illustrates the function. The HL 530 allows demonstration of a heating circuit and representation of domestic water heating. A plate heat exchanger is used to simulate a radiator. Cold water is fed through the heat exchanger as a heating load. A sight glass allows observation of the gas flame in the burner. Built-in thermometers and flow meters allow the recording of measured values to determine the power and efficiency. The unit is operated with liquid gas (propane, connection pressure 50mbar) and is therefore independent of any pre-installed natural gas lines. The panel is attached to the HL 100 Universal Stand (available as an accessory).
