About this file
This document is a set of questions and answers from vendors regarding a solicitation for a 20-Ton Industrial Water Chiller. The key details are:
The chiller must be rated for continuous usage and operate within an ambient temperature range of +14°F to +113°F. It must have a minimum cooling capacity of 20 tons or 239,756 BTUs/hr, using water as the cooling medium with a minimum flow rate of 50 GPM. The chiller must use R-410A refrigerant and have a noise rating not to exceed 69 dB at 32 feet.
The chiller must have a self-contained 55-gallon minimum stainless steel water reservoir and be powered by a 460V, 3-phase, 60Hz electrical supply. The system must fit within specific size and weight requirements, be self-contained on a movable skid/frame, and maintain clearance spacing of at least 6.5 feet on the sides and 10 feet above. Newer refrigerants may be used if they are safe for indoor use near personnel and combustion areas.

| Vendor Comment/Question Number | Comment/Question | Program Team Responses |
| 1 | Does the refrigerant have to be R-410a or can it be a newer specification? | Newer refrigerants may be used; but only if they may be used safely indoors, around personnel, and in an engine room with combustion occurring. Any new refrigerant used cannot necessitate storing the chiller outside or in a different facility. |
| 2 | Would a poly reservoir be acceptable versus stainless steel? | Yes, a poly reservoir is an acceptable material for the reservoir because it does not rust, similar to stainless steel. |
| 3 | Is this going to be installed indoors or outdoors? | The chiller will be installed indoors and within twenty-five feet (25’) of working employees. The indoor use requirement also necessitates the noise specifications in the requirements. |
| 4 | If an air-cooled unit is acceptable, will there be adequate room for ventilation for the hot air from the condenser fan? | The room the chiller will be installed in is approximately seventy feet (70’) wide by fifty feet (50’) deep by eighty feet (80’) tall (70’ W × 50’ D × 80’ T). Please keep in mind the chiller’s proximity to working employees, the maximum noise tolerances, working in an engine room/combustion area, and the quoted chiller’s stand-off distances. |
