摘要
One cooling trap is in operation while the other is unconnected. A single vacuum distributor supplies both, and a single cooler and vacuum source serves both. Automatic regulators control switch-over, ensuring continuous running without interruptions or temperature fluctuations. The unconnected trap is pref. first defrosted, then pre-cooled before re-connection.
