Flange immersion heater

Pharma-type flange heaters are designed for efficiently heating liquid or gaseous fluids which are flowing or stagnant. This special model of an electrical flange heater mainly heats ultra-pure fluids. The design of the pharma-type flange heater has especially been matched to this application. The design can be low-pocket or pocket-free. The design is based on the general conditions such as the type and properties of the respective fluid, pressure and temperature as well as the desired operating points in the process. Pharma-type flange heaters directly heat fluids, converting electrical energy in the heating rods to thermal energy. The thermal energy is then transferred from the heating rods to the fluid. Here, it is important that the design be matched to the general conditions, for each fluid has its specific properties. For example, these fluids are heated in Pharma-type flange heaters: I. Ultra-pure water Aqua purificata (AP) and/or cleaned or purified water (PW) Water for injection purposes (WFI) Ultra-clean water as feed water for the generation of ultra-pure steam II. Air Sterilized air III. Other fluids Hydrogen peroxide CIP solutions The fluid to be heated and the application temperature mainly define the materials which can be used for the unheated and/or heated surfaces. Otherwise, corrosion may quickly result in a failure of the electrical flange heater, for example. Materials of the wetted, heated and unheated components Corrosion-resistant stainless steel Titanium, Hastelloy, special materials Special designs of the wetted components Surface roughness Ra < 0.8 µm, lower surface roughness as an option (Ra < 0.6µm, Ra < 0.4 µm)
