What is the Smardt Ultra Series water-cooled chiller?
The Ultra Series is Smardt's large water-cooled centrifugal chiller range. It targets critical and high-tonnage plants. Smardt publishes 300 to 3,600 refrigeration tons. That equals 1,055 to 12,660 kW. Units use several oil-free compressors. Listed refrigerants are R515B, R513A, and R134a. A family limit does not set one machine's duty or efficiency. It also does not set backup level or footprint. Efficiency claims need certified schedules. Buyers should compare yearly plant energy and condenser-water reset limits. They need compressor staging and output after faults. The review must cover refrigerant change risk and service space. It must also cover tube access, controls, cyber access, factory tests, shipping splits, and local staff. One large machine can still be a common failure point. This remains true with several compressors. Designers should compare a few large chillers with more small modules. Both options need the same reserve rule and maintenance case. Compare minimum load, electrical design, pumps, and towers too. The quote should state duty and efficiency tolerance. It should give all entering and leaving water values and fouling factors. It must list the allowed condenser-water range, charge, starting needs, and harmonics. It should show operation after loss of a compressor or power feed. Delivered cost, schedule, long-term reliability, and site test results are not public.
