Passive air vents. Passive air vents allow natural air circulation to flow through a cabinet providing proper ventilation.
Enclosure fans. Enclosure air fans are used when more ventilation is required. The size of the fan will depend on the size of the enclosure as well as the amount of air that needs to be circulated.
Air conditioners. Air conditioners are used when ambient air circulation is inadequate to cool the cabinet. The air conditioner size will depend on the enclosure size, ambient air temperature and heat generated within the cabinet.
Heaters. Heaters are used when a cabinet is located in areas that may be exposed to cold temperatures.
Locking mechanisms. Locking mechanisms are used to secure cabinets.
Conduit hole seals. Conduit hole seals are used on cabinets that have holes that need to be plugged after conduit has been removed.
