Air Cooled Chiller with Screw Variable Speed Compressor

30KAV-ZE

Premium air‑cooled chiller delivering superior part‑load efficiency, low noise, and advanced intelligence

The Carrier AquaForce® Vision 30KAV‑ZE is a high‑capacity air‑cooled chiller designed for commercial and industrial applications requiring exceptional reliability, outstanding energy performance, and advanced connectivity. Featuring variable‑speed screw compressor technology, Greenspeed® Intelligence, and ultra‑low‑GWP refrigerant R‑1234ze, it delivers optimal performance across a wide range of operating conditions, particularly at part load.

  • Outstanding performance
  • Low sound levels
  • Intelligence and connectivity
  • Environmentally responsible
  • Wide range of applications
  • Simple installation and maintenance

Features & Benefits

Outstanding energy performance

  • 2nd generation of Carrier high-efficiency variable-speed twin-screw compressors with built in volume index control (Vi) valve for both optimal full and part load performance
  • Variable-speed Flying Bird™ fans with EC motor minimizing power consumption
  • Novation® aluminum condenser with high-efficiency micro-channel coils technology
  • Optimized electrical performance
  • Hydraulic module with variable-speed dual pump
  • Smart energy monitoring

Built-in reliability and easy servicing

  • Screw compressors are industrial-type with oversize bearings and motor cooled by suction gas
  • Variable-speed fans
  • Novation® aluminum micro-channel heat exchangers (MCHE) with high corrosion resistance
  • Flooded evaporator with mechanically cleanable water tubes
  • Two independent refrigerant circuits to secure partial cooling
  • Auto-adaptive control
  • Exceptional endurance tests

Minimized operating sound levels

  • Greenspeed® Intelligence, featuring variable-speed screw compressors and condenser fans, minimizes noise levels at part load operation
  • New generation of Carrier 06Z variable-speed twin screw compressor with integrated resonator array
  • 6th generation of silent Flying Bird™ fans
  • 4 sound levels to match the most sensitive environments

Easy and fast installation

  • Built-in variable speed pumps up to 800 kW
  • Compact units for easy transportation and installation
  • Simplified electrical connections
  • Simplified water connections
  • Fast commissioning

Environmental care

  • Automatic energy meter
  • PUREtec™ R-1234ze long-term refrigerant solution
  • 40% less refrigerant allowed by the micro-channel technology
  • Leak tight refrigerant circuits
  • Refrigerant leak alert
  • Refrigerant leak detection (option)

Designed to support Green Building Design

LEED® (Leadership in Energy and Environmental Design) certification

New generation of Carrier 06Z variable-speed twin screw compressor

  • Twin screw compressor optimized for variable speed operation
  • Separate air-cooled inverter drive for increased reliability
  • Integrated Resonator Array (IRA) to reduce the sound level by up to 6 dB(A) when compared with previous 06T generation
  • Integrated Check Valve for quiet shutdown
  • Bearing life exceeding 100 000 hours
  • A dedicated oil separator is installed at the discharge of each compressor to ensure maximum oil return
  • Volume index control (Vi) valve provides a reliable method of adjusting the compression ratio to better match system demand
  • Screw compressors work on the positive displacement principle to compress gas to a higher pressure. As a result, if there is an unusually high pressure in the condenser, the compressor does not switch off, but continues operation at reduced capacity (unloaded mode)
  • The silencer in the oil separator line considerably reduces discharge gas pulsations for much quieter operation

Control / Integrations

SmartVu™ control

  • Intuitive and user-friendly, coloured, 7" interface
  • 10 languages available
  • Easy access to the controller box
  • Password protection
  • Night-mode
  • Energy management

Remote management as standard

  • Easily accessed from the internet
  • Multiple remote control, monitoring and diagnostic possibilities
  • Optional communication gateways
  • Start/Stop of the machine
  • Dual set-point management
  • Water pump control

Remote management (EMM option)

Extended remote control possibilities: room temperature, set-point reset, etc.
