When plastics are dried which produce hazardous gases, environmentally sound disposal of the regeneration exhaust air must be provided. The throughput of the regeneration blower may not be changed.

It must be taken into consideration when installing a disposal system (e.g. exhaust system) that regeneration exhaust air is extremely humid. This may result in condensation water which must not enter the dryer again under any circumstances.

F

A return air cooler is generally required in cases in which the return air temperature is over 65 °C (149°F).
