Features and Benefits

Advanced Heat Transfer Surfaces

•Evaporator and condenser tubes use the latest heat transfer surfaces

•Less refrigerant needed due to advanced patented evaporator design

Compact Size

•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

Simple Installation

•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

Environmental Features and Benefits

Improved Efficiency:

•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

Reduced Emissions:

•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

Additional Features and Benefits

•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

CVGF specifications

The Trane CVGF series is a revolutionary innovation in the world of commercial HVAC systems, designed to deliver unparalleled performance and energy efficiency. This air-cooled chiller line is specifically engineered to meet the demands of modern buildings, making it an ideal choice for various applications such as offices, hospitals, and educational institutions.

One of the standout features of the CVGF series is its use of the Trane Adaptive Control technology. This advancement provides the system with real-time data analytics, allowing it to automatically adjust cooling output based on environmental conditions and load requirements. This level of adaptability not only enhances occupant comfort but also contributes to significant energy savings, aligning with sustainability goals.

The CVGF chillers also incorporate a robust and efficient scroll compressor, which operates quietly and minimizes vibration. This design choice ensures reliability and longevity while reducing operational noise levels, making it suitable for installations in noise-sensitive environments. Furthermore, the scroll compressor's efficiency plays a crucial role in achieving a higher coefficient of performance (COP), which translates to lower energy costs.

In terms of environmental responsibility, the CVGF series is designed with an eco-friendly refrigerant that supports lower global warming potential (GWP). Committed to sustainability, Trane ensures that these chillers not only meet but exceed regulatory requirements, allowing businesses to operate with a reduced carbon footprint.

Another remarkable characteristic of the CVGF line is its modular design, which simplifies installation and maintenance. The units are compact and can be easily integrated into existing infrastructure, minimizing disruption during upgrades or replacements. The straightforward maintenance protocols further enhance the system’s uptime, ensuring users enjoy consistent and reliable cooling performance.

Moreover, the CVGF chillers are equipped with advanced monitoring capabilities, accessible through Trane’s proprietary software. This feature enables facility managers to oversee system performance from any location, facilitating proactive adjustments and timely maintenance interventions.

Overall, the Trane CVGF series stands out as a cutting-edge solution for effective and sustainable cooling in commercial applications. By combining innovative technologies, energy-efficient design, and user-friendly features, the CVGF offers a comprehensive approach to achieving optimal climate control while meeting the challenges of the future.
