Series E™ CenTraVac™ CVHH/CDHH Water-Cooled Chillers

Cooling capacity: 3000 - 14000 kW

  • Direct drive multistage compressors
  • Semi-hermetic compressor design
  • Rapid restart after power failure
  • Economizer
  • Tracer AdaptiView™ Controls

Highest Efficiency

Proven design of compressor in conjunction with use of low pressure refrigerant R1233zd(E) and standard fitted economizer provide market-leading efficiencies:

• Exceeding 10 percent more efficient than any other centrifugal chiller design
- Direct drive compressor provides 2 to 3 percent better efficiency
- Multi-stage design with integrated flash economizer drives 5 to 7 percent better cycle efficiency
• The industry’s most efficient, low pressure, next-generation, low-GWP refrigerant.
• Duplex™ chiller design utilizing series counterflow arrangement provides the industry’s highest efficiency for large tonnage applications

Most reliable

For the last 80 years, Trane has been building centrifugal chillers with design fundamentals and proven technology. Trane centrifugal compressors achieve the industry’s highest design reliability rating of 99.7 percent:

• Unmatched direct drive compressor reliability through simplicity of design and fewer moving parts
• Semi-hermetically sealed motors operate in a cool, clean environment to extend the life of the chiller
• Tracer AdaptiView™ controller with patented algorithms anticipate and correct situations to keep the chiller online
• Extensive factory testing available to verify operation at customer-defined conditions

Environmental Stewardship

• Near-zero global warming potential with R-1233zd(E), a next-generation, low-GWP refrigerant that is one of the few non-flammable olefin options available today
• Low pressure, leak-tight design keeps refrigerant inside the chiller
• Patented EarthWise™ purge auto-regeneration cycle reclaims refrigerant for return to the refrigerant cycle
• Energy saving options reduce water and heating plant consumption: free cooling, thermal storage, heat recovery, heat pump and Adaptive Frequency™ drives

  • As with all CenTraVac™ chillers, selection options ensure units are built to customer's specific requirements. From energy saving options to the enhanced electrical package and a variety of low and medium voltage options, a Trane chiller will be customized to your needs.
