Alfa Laval Heating and Cooling Hub
www.alfalaval.comwater is cooled through direct contact with air. • Indirect heat exchanger, where both media are separated by a wall through which heat is transferred. Heat transfer theory Heat can be transferred by three methods. • Radiation – Energy is transferred by electromagnetic radiation. One example is the heating of the earth by the sun.
Jacketed Heating - Chemical Processing
www.chemicalprocessing.comHeat/Cool Systems for Jacketed Heating Pick Packaged Systems deliver tempered water at precise and uniform temperature (within 1°C). For jacketed heating systems, this provides better process control while cutting costs. No steam traps or expansion tanks are required, and energy costs are cut dramatically as compared with indirect heaters.
