NATO Supply Class 4420 refers to the category of Heat Exchangers and Steam Condensers within NATO Supply Group 44. This supply class is specifically related to equipment used in the fields of Furnace, Steam Plant, and Drying Equipment, as well as Nuclear Reactors.

Heat exchangers are devices that transfer heat between two or more fluids, while steam condensers are used to convert steam back into water by cooling it down. These components play a crucial role in various industrial processes, including power generation, chemical processing, and HVAC systems.

In the context of NATO Supply Group 44, which encompasses Furnace, Steam Plant, and Drying Equipment, as well as Nuclear Reactors, the heat exchangers and steam condensers in Class 4420 are essential for efficient heat transfer and energy management within these systems.

Nuclear reactors, which are also included in this supply group, are used for generating nuclear power by harnessing the energy released from nuclear reactions. Heat exchangers and steam condensers are integral components of nuclear power plants, as they help in the cooling and conversion of steam produced by the reactor.

Overall, NATO Supply Class 4420 for Heat Exchangers and Steam Condensers in NATO Supply Group 44 represents the equipment necessary for heat transfer and energy management in various industrial processes, including those related to furnace, steam plant, drying equipment, and nuclear reactors.

What is an Industrial Fluid Cooler? 1608 Items
An Industrial Fluid Cooler (COOLER,FLUID,INDUSTRIAL) is an apparatus designed to lower the temperature of a fluid by bringing it into proximity with another fluid of lower temperature so that heat transfer is effected by conduction through the walls of separating chambers. Excludes air conditioning equipment, refrigeration equipment, and radiators.
What is an Industrial Fluid Heater? 301 Items
An Industrial Fluid Heater (HEATER,FLUID,INDUSTRIAL) is an apparatus designed to raise the temperature of a fluid by bringing it into proximity with another fluid of higher temperature so that heat transfer is effected by direct contact or by passing those fluids through pipe(s), tube(s), or coils which are submerged in a tank of hot water or steam which is supplied from an outside source. The fluid is never stored in this tank. Excludes air conditioning, electric fluid heaters, and refrigeration equipment.
What is a Surface Steam Condenser? 80 Items
A Surface Steam Condenser (CONDENSER,STEAM,SURFACE) is an apparatus in which steam and a cooling medium of water and/or air are directed through separate chambers and condensation is effected by abstracting the heat from the steam by conduction through metal.
