  • PT - heating capacity
  • Tp1 - air temperature at the unit inlet
  • Tp2 - air temperature at the unit outlet
  • Tw1 - heating medium temperature at the heat exchanger inlet
  • Tw2 - heating medium temperature at the heat exchanger outlet
  • Qw - heating medium flow rate in heat exchanger
  • Δpw - heating medium pressure drop in heat exchanger

If you want to calculate heating capacity at different parameters you can do this at manufacturer website.

Industrial buildings - INOX The LEO INOX heater has been developed to meet a high level of humidity, which is why it can be used in facilities such as: car washes, industrial workshops, food industry production halls, greenhouses etc.
  The stainless steel housing of the device ensures its durability against corrosive agents. To retain its anti-corrosion properties, it must be continuously kept clean.
  The heat exchanger is built of copper pipes with aluminium lamellas on them.
Selection

Selection - to choose the appropriate INOX steel grade of which the heater housing will be made, the parameters of the working environment must be determined appropriately: the type of substances causing corrosion, pH, humidity, etc.
