<p>A first liquid container has therein a level control including a float valve, a storage tank or second container and a third container having therein a liquid which is maintained at a fixed liquid level. The third container is connected to the liquid in the first container by the float valve, and is replenished by the liquid in the storage tank. Preferably the storage tank is designed as an evaporator, with a condensate separator plate or surface arranged above the third container which also has an overflow to the storage tank. A temperature stabilizer keeps the liquid in the first liquid container at a temperature above ambient, and the storage tank is in contact with the liquid in the first container to be warmed thereby, and the condensate separator is cooled by ambient air.</p> |
