\u2022 Max. allowed water temperature 100\u00b0C.<\/p>\n
\u2022 Max. allowed pressure 1.6 MPa.<\/p>\n
\u2022 The nomograms show the operating parameters of the heaters for normal water temperature drop, different flow rates and air temperature at the inlet.<\/p>\n
The rules for choosing the location of the heater in the ventilation system are the following:<\/p>\n
\u2022 If the heat carrier is water, the heaters are intended only for indoor use in rooms where the temperature must be higher than the freezing point of water.<\/p>\n
\u2022 External use is possible only in case the coolant is a non-freezing mixture (for example, ethylene glycol solution). Water heaters can work in any position that is provided by their deaeration.<\/p>\n
\u2022 Access for maintenance and control over the heater must be provided. An air filter must be installed before the heater to protect it from contamination.<\/p>\n
\u2022 To achieve the maximum power, the heater must be connected as counterflow.<\/p>\n
\u2022 If the heater is in front of the fan, its power must be adjusted so that it does not exceed the maximum allowable temperature of the air transferred by the fan.<\/p>\n
\u2022 If the heater is located behind the fan, it is recommended to design an element between the fan and the heater that stabilizes the air flow (for example, an air duct with a length of 1 – 1.5 m).<\/p>\n","protected":false},"excerpt":{"rendered":"
