The Electro Fluid Power Learning System provides learners with the components to set up a variety of industrial relay control circuits using ladder diagrams and Boolean logic. Electro Fluid Power Learning System can be used with eight different basic pneumatic or hydraulic learning systems to teach electrical relay control of hydraulic and pneumatic systems and their industry applications. Some of these components include selector, pushbutton, limit, and pressure switches; control and timer relays and hydraulic and pneumatic directional control valves. Learners will practice industry-relevant skills related to these new topics including developing a sequence of operations given an application, connecting and operating an indicator lamp given a ladder diagram, and many more. In addition to strong curriculum and industry-standard parts, the Electro Fluid Power Learning System includes an instructors guide, install guide, student reference guide, and the option to purchase an interactive multimedia format of the curriculum. The learning systems that can be used with the Electro Fluid Power Learning System include Basic Hydraulics, Basic Pneumatics, Double-Sided Hydraulics, Double-Sided Pneumatics, Basic Fluid Power, or Double-Sided Basic Fluid Power.

Gas meter.
The components are clearly but compactly arranged in a manner similar to that used for many domestic air-water heat pumps and all are visible from the front of the unit.
The Water Water Heat Pump consists of a hermetic compressor, an efficient plate heat exchanger condenser and evaporator, a liquid receiver, a thermostatically controlled expansion valve.
The operating cycle is as follows:
Slightly superheated Refrigerant vapour enters the compressor from the evaporator and Water Water Heat Pump pressure is increased. Heat is given up to the cooling water and the refrigerant condenses to a liquid before passing to the liquid receiver and then the expansion valve. This brings about a rise in temperature and the hot vapour enters the water cooled plate condenser.
