Heat Exchanger Vacuum Breaker - Shell and Tube Heat Exchanger

WVBSS vacuum breaker is used on heat exchangers, air coils, jacketed kettles, pressing machines, boiler feed water tanks, sparge systems, water lines or anywhere else an unwanted vacuum may occur. The WVBSS allows air to enter the steam or liquid system in order to 'break the vacuum' caused by the condensing of steam or draining of liquid from

Steam Consumption of Heat Exchangers | Spirax Sarco

A shell and tube heat exchanger used to heat water for space heating (using either steam or water) is often referred to as a non-storage calorifier. (A storage calorifier, as shown in Figure 2.13.1, is constructed differently, it usually consists of a hot water storage vessel with a primary heating coil inside).

Plate Heat Exchanger (PHE) - saVRee

Introduction. Plate heat exchangers are one of the most common types of heat exchanger employed today; the other common type of heat exchanger is the shell and tube heat exchanger.The spiral heat exchanger is also used for industrial applications, but its use is minor compared to the other two types of heat exchanger.

Ground-coupled heat exchanger - Wikipedia

A ground-coupled heat exchanger is an underground heat exchanger that can capture heat from and/or dissipate heat to the ground. They use the Earth's near constant subterranean temperature to warm or cool air or other fluids for residential, agricultural or industrial uses. If building air is blown through the heat exchanger for heat recovery ventilation, they are called earth tubes (also

Install a Heat Pump Water Heater to Save Cash

Like a conventional water heater, a heat pump water heater still uses electricity but it just does it a little smarter. How so? Instead of using the electricity to directly heat the water through an element that has to run constantly in order to keep it hot, it moves the heat from the air outside of the tank into the inside of the tank to heat
