      The NKD heater parameters calculation example:

      • It is necessary to select a heater for supply air post-heating to a temperature of +24 °C, provided the temperature downstream of the heat exchanger is +17 °C. Therefore, it is essential to increase temperature by 7 °C. The ventilation system incorporates the VENTS VUT 350 VB EC A19 air handling unit. The rated air capacity is 400 m3/h. Determine the intersection of the post-heating temperature line (+7 °C) and the rated air capacity line (400 m3/h).
      • In this case the 1200 W heater capacity provides necessary post-heating (+7 °C). The NKD heater 160-1.2-1 kW with the diameter matching the spigot diameter of the air handling unit VUT 350 VB EC A19 is a suitable model.
