ProSonix Improves Heating Process
Steam injection heating can be used for a variety of heating applications. Inline heating of water and high solids slurries are common. Typical applications are CIP hot water, boiler feedwater heater, paper machine whitewater and shower water, chemical jacketed reactor water heating, etc. Designs of steam injection heaters vary and sometimes using common generic brand names such as hydroheater or pick heater to select your heater may limit your options. When selecting your steam injection heater, make sure you specify the brand name you are looking for. ProSonix offers a diversified line of steam injection heaters to fit your specific application needs. Just searching for or requesting a hydroheater or pick heater may lead to selecting the wrong heater. Our ProJet steam injection heater is a simple and inexpensive inline water heater. It is a good replacement for shell and tube heater exchanger or plate and frame heat exchangers. Our ProJet steam sparger is a great fit for tank heating applications. Both provide precise temperature control and can eliminate rough operation from steam hammer (also referred to as water hammer) for trouble free operation. Our ProSonix ProJet heater and steam sparger is a good choice for hot water tank heating, adding additional heat to central hot water systems, and boiler feedwater heating applications.
