Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
52 words
Solvent condenser arrangement for a solvent recovery apparatus, wherein at least two solvent condensers are provided, of which one is in operation at a time, while the other one is defrosted, and wherein the at least two solvent condensers are supplied alternately via a pump from a refrigerant container under vaporization pressure.
Claim 2
Dependent Claim
52 words
Solvent condenser arrangement for a solvent recovery apparatus, wherein at least two solvent condensers are provided, of which one is in operation at a time, while the other one is defrosted, and wherein the at least two solvent condensers are supplied alternately via a pump from a refrigerant container under vaporization pressure.
Claim 3
Dependent Claim
20 words
Solvent condenser arrangement according to claim 1, in which the refrigerant vaporizer of a refrigerating machine serves as refrigerant container.
Claim 4
Dependent Claim
35 words
