Abstract

A hydronic system separator has an air separator with a vent release mechanism to remove air from the fluid within a hydronic system. The separator includes a magnetic assembly for collecting ferrous particles from the fluid. One or more screens are used to remove other particles from the fluid. The separator housing includes a removable debris collection receptacle that has a drain assembly.

First claim

The invention claimed is:

1. A hydronic system separator comprising:
a housing having an upper section and a lower section that is releasably coupled to said upper section, said housing having an internal chamber with an upper portion, a lower portion, and a medial portion therebetween;
an air separator removably coupled to said upper section with O-ring positioned between a surface of said air separator and said upper section, said air separator having a diaphragm positioned over the top of said upper portion of said internal chamber;
spaced apart first openings in said housing to permit fluid to pass through said housing in a first direction;
spaced apart second openings in said housing to permit fluid to pass through said housing in a second direction;
at least one internal filter positioned on an internal ledge on said upper section withim said upper portion of said internal chamber, said at least one internal filter being in between said spaced apart first openings;
a magnetic bar removably coupled to said lower section of said housing to position said magnetic bar at an angle between a vertical and a horizontal position within said lower portion of said internal chamber; and
a drain valve coupled to said lower section of said housing.

2. The hydronic system separator of claim 1 , wherein said magnetic bar position is approximately 45° with respect to a longitudinal centerline of said housing.

3. The hydronic system separator of claim 1 , including at least one internal filter positioned within said medial portion of said internal chamber between said spaced apart second openings.

4. The hydronic system separator of claim 1 , including a temperature and pressure gauge coupled to said upper section of said housing, in fluid communication with said upper portion of said internal chamber.

5. The hydronic system separator of claim 1 , wherein said at least one internal filter is a stainless steel coalescing filter.

6. The hydronic system separator of claim 1 , wherein said magnetic bar is positioned within a protective sleeve.

7. The hydronic system separator of claim 6 , wherein said magnetic bar is rated 12,000 Gauss or higher.

8. A separator assembly comprising:
a housing having an upper section and a lower section that is releasably coupled to said upper section, said housing having an internal chamber with an upper portion, a lower portion, and a medial portion therebetween;
an air separator removably coupled to said upper section with O-rings positioned between a surface of said air separator and said upper section, said air separator having a diaphragm positioned over the top of said upper portion of said internal chamber;
spaced apart first openings in said housing to permit fluid to pass through said housing in a first direction;
spaced apart second openings in said housing to permit fluid to pass through said housing in a second direction;
at least one first internal filter positioned on an internal ledge on said upper section within said upper portion of said internal chamber, said at least one internal filter being in between said spaced apart first openings;
a magnetic bar removably coupled to said lower section of said housing to position said magnetic bar at an approximately 45° angle with respect to a longitudinal centerline of said housing; and
a drain valve coupled to said lower section of said housing.

9. The separator assembly of claim 8 , including at least one second internal filter positioned within said medial portion of said internal chamber between said spaced apart second openings.

10. The separator assembly of claim 8 , including a temperature and pressure gauge coupled to said upper section of said housing, in fluid communication with said upper portion of said internal chamber.

11. The separator assembly of claim 8 , wherein said at least one first internal filter is a stainless steel coalescing filter.

12. The separator assembly of claim 9 , wherein said at least one second internal filter is a stainless steel coalescing filter.

13. The separator assembly of claim 8 , wherein said magnetic bar is positioned within a protective sleeve.

14. The separator assembly of claim 13 , wherein said magnetic bar is rated 12,000 Gauss or higher.

15. A hydronic system separator assembly comprising:
a housing having an upper section and a lower section that is releasably coupled to said upper section, said housing having an internal chamber with an upper portion, a lower portion, and a medial portion therebetween;
an air separator removably coupled to said upper section with O-ring positioned between a surface of said air separator and said upper section, said air separator having a diaphragm positioned over the top of said upper portion of said internal chamber;
spaced apart first openings in said housing to permit fluid to pass through said housing in a first direction;
tubing coupled to said spaced apart first openings;
spaced apart second openings in said housing to permit fluid to pass through said housing in a second direction;
tubing coupled to said spaced apart second openings;
at least one internal filter positioned on an internal ledge on said upper section within said upper portion of said internal chamber, said at least one internal filter being in between said spaced apart first openings;
a magnetic bar removably coupled to said lower section of said housing to position said magnetic bar at an angle between a vertical and a horizontal position within said lower portion of said internal chamber; and
a drain valve coupled to said lower section of said housing.

16. The hydronic system separator assembly of claim 15 , wherein said angled position is approximately 45° with respect to a longitudinal centerline of said housing.

17. The hydronic system separator assembly of claim 15 , including at least one internal filter positioned within said medial portion of said internal chamber between said spaced apart second openings.

18. The hydronic system separator assembly of claim 15 , including a temperature and pressure gauge coupled to said upper section of said housing, in fluid communication with said upper portion of said internal chamber.

19. The hydronic system separator assembly of claim 15 , wherein said at least one internal filter is a stainless steel coalescing filter.

20. The hydronic system separator assembly of claim 15 , wherein said magnetic bar is positioned within a protective sleeve.
