Preventing the recirculation of hot air

Vertical air baffle

Outside the cabinet

Prevent hot air circulation outside the cabinet by leading the outcoming hot air away
from the area where the inlet air to the cabinet is taken. Possible solutions are listed
below:
• gratings that guide air flow at the air inlet and outlet
• air inlet and outlet at different sides of the cabinet
• cool air inlet in the lower part of the front door, and an extra exhaust fan on the
roof of the cabinet.

Inside the cabinet

Prevent hot air circulation inside the cabinet with leak-proof air baffles at the
positions shown in the diagrams in chapter
usually required.

Cubicle heaters

Use a cubicle heater if there is a risk of condensation in the cabinet. Although the
primary function of the heater is to keep the air dry, it may also be required for
heating at low temperatures. When placing the heater, follow the instructions
provided by its manufacturer.
