2. Description

2-1 . General

Delta Heat Exchanger (HEX) is designed for direct air to air heat

exchange to remove heat from the cabinet.

The internal and the external air circulation loops of the HEX are
separated to prevent the introduction of dust, humidity and dirt. The fan on
the external air loop conforms to IP55 protection rating.
