Heat transfer through the walls glass. The water temperature here is in the range 88-92 C. During the cycle, cold water in heat exchanger poostupaet glass through the injector. The water then moves the glass on heat transfer in a group of the Strait (4). You may want to visit Author to increase your knowledge. When the machine is at rest, the water is constantly circulating between the band and the Strait of glass heat exchanger, while maintaining their optimum temperature for coffee.
Each group has its own strait heat exchanger glass. In our case, the coffee machine has a single group and, accordingly, a heat exchanger glass. (3) – Electric heating element heater. Heats the water in the boiler is located within it. Temperature teploelektronagrevateley controlled by a thermostat. If you exceed the maximum permissible temperature, the machine cuts off the electricity. The model under consideration has a capacity of 1800 W Tan.
(4) – Group Strait (cooking, coffee, transfer) Group Strait cast in brass and placed the camera in her tea leaves. Pressing any button control panel, comes into force pump (5). Of heat-exchange glass (2) water for espresso comes a group of strait and pass through it under pressure 9.8 bar, created by the pump. (5) – Pump Pump comes into action when you press any button on the control panel, raising the pressure in the system 8-9 Bar, necessary for making coffee. Pump also receives signals from the control of water level, which supports the amount of water in the boiler. (6) – Crane hot water faucet This is designed to feed Hot water from the boiler.
