|
|
| ||
| Cooling Capacity: | Total capacity of the chiller to remove heat from the process fluid. Typical units are kilowatts, tons of refrigeration, or BTU/hour. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Fluid Discharge Temperature: | Required temperature of fluid discharge. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Compressor Motor Horsepower: | This is a nominal value by which chillers can be approximately specified. True differentiating specifications are capacity and discharge temperature. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||

Condenser Cooling
Back to Top
|
|
| ||
| Condenser Cooling | |||
| Your choices are... | |||
| Air-Cooled | Forced air, usually via fan, passes over condenser coils for cooling. | ||
| Water-Cooled | Condenser coils are cooled with circulating water. | ||
| Remote Air / Split System | Split systems are configured with the main chiller system in the application area, and the condenser is remotely located, often outdoors. The cooling air is supplied remotely to the chiller system. | ||
| Other | Other unlisted, specialized, or proprietary condenser configuration. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
