A hot runner controller is a temperature controller used to control the temperature in the hot runner. This helps create the most consistent part(s). Hot runners usually make the mold more expensive to manufacture and run, but allow savings by reducing plastic waste and by reducing the cycle time. (do not have to wait until the conventional ...
Mengeneinstellung = Volume control. A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures to prevent scalding. The storage of water at high temperature removes one possible breeding ground for Legionella; the use of a thermostat, rather than a static ...
Gas water heaters have an exhaust vent or one to two exhaust pipes on the top, and still require electric power for electronics, sensing and ignition. A three-phase, 21 kW, 400-volt tankless water heater in Europe, with new European color coding for three-phase power. There are also heaters that use several single-phase circuits instead.
Although flange fittings are bulky, they perform well in demanding applications such as large water supply networks and hydroelectric systems. Flanges are rated at 150, 300, 400, 600, 900, 1500, and 2500 psi; or 10, 15, 25, 40, 64, 100, and 150 bars of pressure. Various types of flanges are available, depending on construction.
Indoor mold (American English) or indoor mould (British English), also sometimes referred to as mildew, is a fungal growth that develops on wet materials in interior spaces. Mold is a natural part of the environment and plays an important part in nature by breaking down dead organic matter such as fallen leaves and dead trees; indoors, mold ...
A shower is a place in which a person bathes under a spray of typically warm or hot water. Indoors, there is a drain in the floor. Most showers have temperature, spray pressure and adjustable showerhead nozzle. The simplest showers have a swivelling nozzle aiming down on the user, while more complex showers have a showerhead connected to a hose ...
A water heater that maintains desired temperature by turning the applied power on and off (as opposed to continuously varying electrical voltage or current) based on temperature feedback is an example application of bang–bang control. Although the applied power switches from one discrete state to another, the water temperature will remain ...
For example, a temperature-controlled circulating bath has two PID controllers in cascade, each with its own thermocouple temperature sensor. The outer controller controls the temperature of the water using a thermocouple located far from the heater, where it accurately reads the temperature of the bulk of the water.
