5 Colo. Code Regs. § 1001-29-D
The specifications in this Appendix apply only to vapor degreasers that have both condenser coils and refrigerated freeboard chillers. (The coolant in the condenser coils is normally water.) The amount of refrigeration capacity is expressed in Calories/Hour per meter of perimeter. This perimeter is measured at the air/vapor interface. For refrigerated chillers operated below 0°C., the following requirements apply:
DEGREASER WIDTH | *CALORIES/HR METER OF PERIMETER | BTU/HR FOOT OF PERIMETER |
Less than 1.1 meters (3.5 ft.) | 165 | 200 |
1.1 - 1.8 meters (3.5- 6.0 ft.) | 250 | 300 |
1.8 - 2.4 meters (6.0- 8.0 ft.) | 335 | 400 |
2.4 - 3.0 meters (8.0 - 10.0 ft.) | 145 | 500 |
Greater than 3.0 meters (10 ft.) | 500 | 600 |
* Kilocalories (1 Kilocalorie = 4184.0 joules)
For refrigerated chillers operating above 0°C., there shall be at least 415 Calories/Hr. - meter of perimeter (500 BTU/Hr-ft.), regardless of size.
Definition: "Air/Vapor Interface" - means the surface defined by the top of the solvent vapor layer within the confines of a vapor degreaser.
