SEALING THE DEAL

When designing an HVAC unit, there are many things to consider. Will it be used in a cold or warm climate? Will it be exposed to the sun, rain, snow, salt water or sand? Will there be a weekly need for access to the technology inside? Are there any specific security aspects to consider?

KEEPING THE PRESSURE JUST RIGHT

In general terms, the most crucial aspect of a latching solution for HVAC units is that it ensures the cabinet is sealed properly. The latches, hinges, profiles and cut-outs need to be designed in a way that makes the whole door completely sealed.

Another important aspect to having a properly sealed unit is if the air pressure inside is positive or negative. The reason for this is that a negative air pressure draws the door inwards, while a positive air pressure pushes it outwards. This affects latches and sealing profiles in very different ways.

SAFETY IS KEY

The air pressure inside also affects the way a door behaves when it is opened. Therefore, an HVAC latch needs to be opened in two stages. The first stage should only open the door enough to depressurise the unit, so it is completely safe to open the door fully in the second stage.

When people enter large HVAC units, they need to be sure they can always get out, in case of a door slamming shut or if something happens while they are working inside. This is why an inside security handle should be a part of every solution for this type of unit.
