Doyle & Roth Manufacturing has served the chemical and process industries since 1932. We specialize in heat exchangers, plate heat exchangers and shell and tube heat exchangers. See our website for more information.
Heat exchangers are pieces of equipment used to transfer heat between two or more fluids. This process usually involves abundant working or utility media such as water or air that rejects or absorbs heat from a more valuable fluid such as crude oil, petrochemical feedstocks, and fluidized products...
A shell and tube heat exchanger (STHE) is a type of heat exchanging device constructed using a large cylindrical enclosure, or shell, that has bundles of perfectly spaced tubing compacted in its interior. Heat exchanging is the transfer of heat from one substance or medium to a similar substance or medium...
A plate heat exchanger (PHE) is a compact type of heat exchanger that utilizes a series of thin metal plates to transfer heat from one fluid to the other. These fluids are typically at different temperatures...
A chiller is a cooling mechanism designed to produce fluids that can lower temperatures by removing heat from the fluid. The type and use of a chiller depends on the required temperature and kind of refrigerant, which can be a liquid or a gas...
Cooling towers are specialized heat exchangers that remove heat from water mainly by means of latent heat loss from evaporation while coming into contact with an airstream. Aside from evaporative cooling, water is also cooled by sensible heat transfer due to the temperature difference between air and water...
A steam boiler is a steam producing heating system. It creates energy by heating water to get steam. It is a heat exchanger that makes steam for outside usage and has a combustion chamber and water container. The several varieties of steam boilers include...
