Mechanical Specifications

Compressor-Motor Starter

Unit-mounted starters can either be a star-delta or solid-state in NEMA 1 type enclosure rated up to 952 RLA at 380-480 Volts (star-delta), 900 RLA at 481-600 Volts (star-delta), and 1472 RLA at 380-600 Volts (solid-state).

Remote-mounted starters can either be star-delta or solid-state for low voltage. Across-the-line, primary reactor, or autotransformer for medium and high voltage. All in NEMA 1 type enclosures up to 1402 RLA at 380-600 volts (star-delta), 1472 RLA at 380-600 Volts (solid-state), and 360 RLA at 3300-6600 Volts (x-line, primary reactor, and autotransformer).

Unit-mounted or remote-mounted starters for Europe (CE mark) will be star-delta, solid-state, across-the-line, primary reactor, and autotransformer only in a IP 10 enclosure.

A steel panel door with optional mechanical interlock disconnects the system when the door is opened (required for CE listing). The panel also contains three-phase current transformer for overload protection, and an oil pump starter with overloads. The starter is factory mounted and wired to the compressor motor and the control panel. The CVGF chiller/starter assembly is factory tested.

Optional remote-mounted electromechanical starters are available.

Isolation Pads

Molded neoprene isolation pads are supplied with each chiller for placement under all support points. Spring isolators are optionally available.

Refrigerant and Oil Charge

A full charge of oil is supplied with each unit. The oil ships in the unit’s sump and the refrigerant ships directly to the job site from refrigerant suppliers.

Painting

All painted CVGF surfaces are coated with two coats of air-dry, beige primer-finisher prior to shipment.

Insulation

The chiller can be ordered with or without factory-applied insulation. Factory-supplied insulation is applied to all low temperature surfaces including the evaporator, water boxes and suction elbow. Insulation material is 19mm (¾ in.) Armafl ex II or equal (thermal conductivity = 0.04 W/m·℃; 0.3 Btu·in/h·ft²·°F). The oil sump is covered with 9.5 mm (3/8 in.) and 13 mm (½ in.) insulation.

Rigging

Evaporator and condenser tube sheets provide rigging support points. A rigging diagram is affi xed to the chiller.

Quality

The chiller manufacturing facility is ISO 9001 certifi ed.

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.
