Sample collector and components thereof

1. A unitary frame for connection to a refrigerated system, comprising:

a support unit adapted to be mounted to the refrigerated system;

said refrigerated system including a refrigerated sample bottle compartment and a refrigeration system;

a refrigeration-system and sample-bottle-compartment housing enclosing the refrigeration system and the refrigerated sample bottle compartment;

condenser and evaporator coils mounted to the support unit;

a restrictor mounted to the condenser and evaporator coils to permit communication thereinbetween while maintaining a pressure differential;

said restrictor being mounted to said support unit;

fastening means for connecting said condenser and evaporator coils to a compressor and for connecting the compressor to the support unit;

means for moving the support unit with the attached condenser and evaporator coils and the restrictor as a unit with respect to a refrigerated sampler and for fastening the support unit to the refrigerated sampler to close the refrigerated sampler as a final closure.

2. The unitary frame of claim 1 further including connectors connecting the evaporator and condenser coils and the restrictor wherein the restrictor is one of an orifice restrictor and a capillary restrictor.

3. The unitary frame of claim 1 in which the evaporator and condenser coils, the restrictor and connectors connecting them have a protective coat formed over them by dipping them in a protective material after they have been mounted to the support unit and the compressor is mounted to the support unit after being coated with the protective coat.

4. A refrigerated sampler, comprising:

a refrigerated compartment adapted to receive sample bottles;

a distributor adapted to supply samples in an orderly manner to the sample bottles;

a pump for pumping samples through the distributor;

a refrigeration system;

an enclosure for the refrigeration system and the refrigerated a cooling compartment adapted to receive a unitary frame;

said unitary frame forming a final closure for the enclosure for the refrigeration system and the refrigerated compartment,

said unitary frame including at least a support member, evaporator coils mounted to the support member, condenser coils mounted to the support member, a condenser providing communication between the evaporator coils and the condenser coils with a pressure differential;

said evaporator coils, condenser coils and a restrictor being connected and mounted in the unitary frame prior to being covered with a protective coat by dipping them in a protective material, whereby an effective seal is provided for the restrictor, condenser coils and evaporator coils.

5. A refrigerated sampler in accordance with claim 4 wherein the condenser coils, the restrictor and the evaporator coils have been coated with a special protective coat after being connected to each other.

6. A refrigerated sampler in accordance with claim 4 in which the restrictor is one of a capillary restrictor and an orifice restrictor.

7. A refrigerated sampler in accordance with claim 4 in which the unitary frame includes a final closure.
