Duct cooling
A dedicated option has been developed to optimise instal-
lation of IP00/chassis frequency converters in Rittal TS8
enclosures. The option uses the fan of the frequency
converter for forced air cooling of the backchannel. Air
that escapes from the top of enclosure could be ducted
outside a facility. Then heat losses from the backchannel
are not dissipated within the control room, reducing air-
conditioning requirements of the facility.
See chapter 3.4.1 Installation of Duct Cooling Kit in Rittal
Enclosures, for further information.
Back cooling
The backchannel air can also be ventilated in and out the
back of a Rittal TS8 enclosure. Such back cooling offers a
solution where the backchannel could take air from
outside the facility and return the heat losses outside the
facility, thus reducing air-conditioning requirements.
