  Temperature Measurement Training Panel

  Four measuring sections with different thermometers can be individually selected using ball valves. The temperatures measured using the resistance thermometer and the thermocouple are displayed digitally. The bimetallic dial and liquid-in-glass thermometers are direct indicating instruments. The response of the measuring devices for different flows can be investigated. The flow rate is measured with a rotameter. The effect of different installation positions and methods on measurement accuracy can be investigated.

  Three Way Mixing Valve Training Panel

  The training panel was designed for heating and plumbing trainees. A three-way mixing valve in a heating system controls the circulation and feed flow temperature of the water flowing in the heating system. A pump circulates the water in the pipe system. The differential pressure across the pipe system is limited using a relief valve. Bimetallic thermometers indicate the temperatures at all relevant points in the heating circuit. It is possible to assemble a complete heating system by adding other training panels from the Series.

  Training Panel Function of Gas Heater

  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 Universal Stand (available as an accessory).

  Valve Loss Training Panel

  Five different pipe sections with various types of shut-off valve are fitted to the training panel. The pipe sections can be individually selected using ball valves. One pipe section with ball valve is made of transparent PVC so that the flow can be clearly observed. A battery-operated digital differential pressure gauge is supplied. The flow rate is adjusted using valves.

  Ventilation System Trainer

  Ventilation systems are often used in building services engineering to achieve the required air change rates in the individual rooms. The ventilation air can also be heated or cooled by heat exchangers. A ventilation system is a preliminary stage for an air conditioning system in which the air can also be humidified or dehumidified. The system is assembled from standard industrial components. The plexiglas windows and exposed ductwork ensure that normally hidden components can be seen: inspection covers and fire dampers, filters, heaters / coolers, louvre damper, etc. The original function is fully retained. The system emphasises ventilation rather.than air conditioning. Depending on the operating mode, heating or cooling, a supply of hot or cold water is required in the laboratory. The system requires a three-phase mains supply.

  Ventilation Trainer

  The designed for training in ventilation engineering. Once the trainee has built a ventilation system independently, the effects of bends, branches, regulator flaps on the airflow rate, the air velocity, as well as the pressure loss can be investigated. For this purpose, an inclined tube manometer with 2 measuring ranges and a digital handheld unit for the measurement of the air velocity are included, along with numerous other components. The individual components in the ventilation system are fitted with pressure measuring glands. The power consumption of the fan is indicated on the switch cabinet using a voltmeter and an ammeter. The components are the same as those used in ventilation engineering.
