Manufacturers and suppliers of Falling Film Absorption for engineering labs worldwide.
Absorption is used to remove one or more gaseous components from a gas flow using a solvent. Selective absorption is an important industrial process for the treatment of gas mixtures. can be used to investigate the basic processes on the water-oxygen-nitrogen system. A compressor supplies ambient air from below into the absorption column. Water flows down as a thin film at the edge of the absorption column. The air flows upwards centrally in the column. A portion of the air's oxygen is dissolved in the water film. The air flow exits the column at the top. The water containing the dissolved oxygen leaves the column at the bottom and flows into a tank. A pump supplies the water with the dissolved oxygen to the head of the desorption column. The desorption column is a simple tube in which the water flows downwards. Nitrogen from a compressed gas cylinder enters at the base of the column. The nitrogen rises to the top in the form of dispersed bubbles in the water. The partial pressure of the oxygen in water is higher than the partial pressure in the gas phase (nitrogen). For this reason, a portion of the oxygen passes over from the water into the gas phase (stripping). This process leads to the water's absorbing capacity for oxygen increasing. A pump supplies the solvent regenerated in this way into a channel circulating the upper part of the absorption column. From here the water again flows along the inner wall of the absorption column as a thin falling film and absorbs a portion of the air's oxygen. The oxygen concentration and temperature are continuously measured both upstream and downstream of the absorption column. Valves and flow meters make it possible to adjust the air flow rate and solvent flow rate. Transparent materials allow optimal observation of the processes in both columns. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. - investigation of the absorption process during the separation of oxygen from an air flow in a falling film column - balance of the process - determination of the mass transfer coefficient ....

Manufacturers and suppliers of Fan Heater / Air Heat Exchanger for engineering labs worldwide.
Experiment module consisting of a fan convector with piping, quick-release couplings and temperature sensors. The experiment module may be used both to heat rooms and to absorb ambient heat from the outside air. It can thus be operated as either a heat sink or a heat source for a heat pump. In the case of heating rooms, compared to traditional heating radiators, fan heaters offer the possibility of achieving a comparatively good transfer of heat to the room air, even at small dimensions. This advantage makes it possible to operate room heating with lower temperatures in the heating circuit. When combined with a heat pump, the fan heater therefore often represents a beneficial application both economically and in terms of energy, especially when renovating heating systems in old buildings. When absorbing ambient heat to supply heat to a heat pump, air heat exchangers are often used when there is no access or difficulty accessing other heat sources such as groundwater or geothermal heat collectors. The disadvantage of the energy balance, particularly unfavourable in winter, in this case is contrasted with the advantage of lower initial investment costs. Carefully structured instructional materials have been created for the recommended module combinations with the module. As part of the documentation for the overall system, these materials set out the basic principles and provide a step-by-step guide through the experiments - Use of a fan convector for heating and cooling rooms - How the temperature difference between the heating feed and return affects the overall efficiency of a heating system - Operating conditions when used as an air heat exchanger in a heat pump system - Comparison of an air heat exchanger with other heat sources in a heat pump system ....

Manufacturers and suppliers of Fatigue Testing Machine for engineering labs worldwide.
Using this experimental unit, the basic principles of fatigue testing can be teached. A rotating metal test bar, clamped at one end, is loaded using a spring balance with a point force. This results in a cyclic bending load on the cylindrical test bar. The amplitude of the cyclic loading can be continuously adjusted using a threaded spindle with hand wheel. After a certain number of load cycles, the test bars breaks as a result of material fatigue. In this case the motor is shut down automatically by the stop switch. The number of load cycles is counted by an electrical counter and displayed digitally. This can also be used for measuring the speed. Differently shaped test bars enable the influence of notching and surface finish on fatigue strength to be demonstrated. - fatigue strength of bars subject to cyclic bending load - influence of different curvature radii and surface finish on fatigue strength - stress-number (S-N) curve....

Manufacturers and suppliers of Fault Finding in Control Systems for engineering labs worldwide.
facilitates practical learning in the control of three controlled variables which are commonplace in process engineering. A circuit with a collecting tank, pump and graduated tank is provided for control of level and flow rate. A pneumatic control valve is used as the actuator. There is a valve in the tank outlet to generate a disturbance variable in level control. Cascade control is possible whereby the level in the tank is controlled by way of the flow rate. Two circuits are used in the control of the temperature. A refrigeration system cools the water in the collecting tank. A pump circulates the water via a heat exchanger (cooling circuit). A heater heats the water in the graduated tank. Another pump also circulates the warm water via the heat exchanger. In the heat exchanger the water in the cooling circuit is heated. The controlled variable is the temperature of the water in the cooling circuit after heating in the heat exchanger. The actuator is the pneumatic control valve which adjusts the flow rate of the warm water. Cascade control is also possible to control the temperature. Two industrial controllers are supplied which can be employed as the master and slave in the implementation of cascade control. They have a Profibus DP interface. This enables the trainer to be controlled by way of a software. The software also permits recording of the process variables and parameterisation of the controllers on the PC. The trainer is equipped with a PLC for monitoring of safety devices, such as a low water cut-off which protects the heater. On the switch cabinet there are also pushbuttons for the simulation of typical faults such as failure of sensors or cable breaks. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. familiarisation with industrial control loop components - set-up, parameterisation and configuration on the controller - optimisation of controller settings - level control - flow rate control - temperature control - cascade control, level - flow rate - cascade control, temperature - flow rate - plotting step responses - fault finding....
