Description of use

WARNING
Danger due to impermissible use of units
Inappropriate use of the units can cause severe accidents.
 Only use air/water heat exchangers in stationary operation.
The Pfannenberg mounting and installation air/water heat exchangers of the series PWS and PWI are designed for
the cooling of the switch cabinet interior air and for diverting heat out of switch cabinets. Sensitive components in
the switch cabinet are protected. Condensate arising during the cooling is removed through a hose.
 The PWI/PWS air/water heat exchangers are only approved for stationary operation.
As air/water heat exchangers of the protection class IP 55, the air/water heat exchangers are for the most part
protected from dust. Limitation: Dust can penetrate after continuous exposure.
The air/water heat exchangers are resistant to spray water, but not a constant water jet.
