Additional Features and Benefi ts
CTV-PRC001-E4
• Evaporator and condenser tubes use the latest heat transfer surfaces
• Less refrigerant needed due to advanced patented evaporator design
• Designed with the retrofi t and replacement market in mind
• The 400 to 500 NTON sizes can fi t through most double-width doors
• Small footprint of the CVGF chiller saves valuable equipment room space
• Simplifi ed piping; the only water piping required is for the evaporator and condenser
• Simple power connection
• Unit mounted starter eliminates additional jobsite labor requirements
• High Effi ciency: 0.55 kW/Ton at ARI conditions
• Motor cooling vented to economizer cycle, effi ciency advantage
• HFC-134 optimized inlet guide vanes and impellers for improved cycle effi ciency using
computational fl uid dynamics
• Over 30 percent joint reduction in compressor/motor assembly compared to previous designs
• Patented integral heaters imbedded into the compressor casting, no seals no leaks
• Beaded fl at gasket technology instead of O-rings, lower susceptibility to developing leaks
• Minimal NPT pipe threads on chiller system, SAE O-ring boss fi tting, lowerleak potential
• Oil sump internal to compressor/motor assembly with internal pump/motor; eliminates vent and
drain lines, leak prevention
• Patented internal oil fi lter prevents leaks and contamination from pipes; fi lter is isolated and easily
replaced
• Advanced evaporator design minimizes the refrigerant charge; a reduced charge reduces the
exposure to the environment in the event of a catastrophic charge loss
• Patented polygon attachment instead of a keyed shaft, self-balancing
• Easy to replace motor terminals
• Motor/stator assembly is easily removed; speed assembly can be removed independent of the
high-speed assembly
• Rolling element bearings
• Hydrodynamic bearings
• Advanced evaporator design: no eliminator necessary with an advanced suction baffl e design
• All metric fasteners
