  • Easy and fast installation
  • Minimized operating sound levels
  • Environmental care
  • Designed to support green building design

General description

  • Inverter-driven screw compressors
  • PUREtec™ R-1234ze refrigerant
  • Touch Pilot control system
  • Flooded heat exchangers that are mechanically cleanable
  • Can provide an evaporator leaving temperature down to 3.3°C
  • Can deliver up to 55°C on the condenser side when operating as a heat pump

Low energy consumption

  • Designed for high performance both at full load and at part load
  • Inverter-driven twin-rotor screw compressors allow precise capacity matching of building load changes and significantly reduce unit power input, especially at part-load
  • Flooded multi-pipe heat exchangers for increased heat exchange efficiency
  • Electronic expansion device permits operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface
  • Optimized electrical performance

High reliability

  • Increased global performance as well as Carrier’s acclaimed product quality and reliability
  • Major components are selected and tested to minimize failures possibility, as well as many design choices have been taken in this perspective
  • Inverter-driven screw compressors with oversized bearings and motor cooled by suction gas
  • The inverter is optimized for each compressor motor to ensure reliable operation and easy maintenance
  • All compressor components are easily accessible on site minimizing down-time
  • Two independent refrigerant circuits (from 1000 kW upwards); the second one automatically takes over, if the first one develops a fault, maintaining partial cooling under all circumstances
  • Auto-adaptive control
  • Exceptional endurance tests

Safe Design

  • Specific polyol ester oil qualified by Carrier for using with HFO-1234ze to guarantee and maintain reliable bearing lubrication
  • Specific compressor gaskets compatible with HFO-1234ze, tested and validated by Carrier
  • New relief valves designed for operation with HFO-1234ze
  • New control algorithms
  • Specific documentation that contains all the installation, operation, maintenance and safety Instructions

Easy and fast installation

  • Compact design
  • Simplified electrical connections
  • Simplified water connections
  • Fast commissioning

Minimized operating sound levels

  • Low noise Greenspeed® variable-speed fans
  • The inverter technology used for the compressor motors minimizes noise levels at part load operation
  • Silencers on the compressor discharge line
  • Sound insulation on the components that are most subjected to radiated noise
  • Option 257 further reduces the global unit sound level

Environmental care

  • R-1234ze HFO long-term refrigerant solution with nearly zero global warming potential (GWP < 1) and zero ozone depletion potential (ODP = 0)
  • Leak-tight refrigerant circuit

Designed to support green building design

  • A green building is a building that is environmentally sustainable and has been designed, constructed and is operated to minimize the total impact on the environment
  • The air conditioning system can use between 30 and 40% of the annual building energy consumption
  • A number of green building certification programs exist in the market and offer third-party assessment of green building measures for a wide variety of building types

Inverter-driven Thunderbolt screw compressor

  • Advanced control algorithms combine inverter frequency output with motor input logic to minimize mechanical part stress, resulting in best compression performance and high chiller reliability
  • Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
  • Screw compressors use positive displacement principle to compress gases at higher pressure. As a result, in case of exceptional high temperature condenser side, the compressor does not switch off, but continues operation at reduced capacity (unloaded mode)
  • The silencer in the discharge line considerably reduces discharge gas pulsations for much quieter operation
  • Condenser includes an oil separator that minimizes the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
