AquaForce®
30XW

Water-Cooled Liquid Chiller
With R-134a Refrigerant

Nominal cooling capacity from 78 to 500 tons
Nominal cooling capacity from 273 to 1,756 kW

The 30XW liquid chillers are the premium solution for industrial and commercial applications where installers, consultants and building owners require optimal performances and maximum quality.

The 30XW liquid chillers are designed to meet current and future requirements in terms of energy efficiency, flexibility of use and compactness. They use the most reliable technologies available today:

  • Twin-rotor screw compressors with a variable capacity valve
  • Refrigerant R134a
  • Touch Pilot control system
  • Flooded heat exchangers that are mechanically cleanable

To meet to all environmental and economic requirements, the 30XW is available in two efficiency classes:

  • Entry-level efficiency 30XW units that offer an optimised balance of technical and economical aspects,
  • Premium-efficiency 30XW-P units that offer unequalled energy efficiency to satisfy the most stringent demands of building owners wanting to reduce operating costs to the minimum.

The 30XW Aquaforce range is also split into two versions:

  • 30XW for air conditioning and refrigeration applications
  • 30XWH for heating applications

As standard, the unit can provide an evaporator leaving temperature down to 3,3°C (-12°C optional), and when operating as a heat pump, it can deliver up to 50°C (63°C optional) on the condenser side.

Performance Features

Low energy consumption

  • SEPR up to 8.0 and SEER up to 7.2
  • The high energy efficiency is reached through:
    • Twin-rotor screw compressor equipped with a high efficiency motor and a variable capacity valve that permits exact matching of the cooling capacity to the load.
    • Flooded multi-pipe heat exchangers for increased heat exchange efficiency.
    • Electronic expansion device permitting operation at lower condensing pressure and improved utilisation of the evaporator heat exchange surface.
    • Economizer system with electronic expansion device for increased cooling capacity (30XW-P).

Low operating sound levels:

  • Silencers on the compressors discharge line.
  • Silencers on the economiser return line.
  • Acoustic insulation on the components that are most subjected to radiated noise.
  • Option 257 further reduces the global unit sound level.

Relaiability Features

  • The 30XW units offer 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.
  • Industrial-type screw compressors with oversized bearings and motor cooled by suction gas.
  • All compressor components are easily accessible on site minimising 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.

Evaporator

  • Electronic paddle-free flow switch. Auto-setting according to cooler size and fluid type.

Auto-adaptive control

  • Control algorithm prevents excessive compressor cycling (Carrier patent)
  • Automatic compressor unloading in case of abnormally high condensing pressure.

Exceptional endurance tests

  • Partnerships with specialised laboratories and use of limit simulation tools (finite element calculation) for the design of critical components.

Maintenance Features

  • All compressor components are easily accessible on site minimising down-time.
  • Reduction of leaks as no capillary tubes and flare connections are used
  • Verification of pressure transducers and temperature sensors without transferring refrigerant charge
  • Discharge line shut-off valve and liquid line service valve for simplified maintenance.

Installation Features

Compact design

  • The 30XW units are designed to offer the most compact dimensions on the market.
  • With a width of approximately 1 m up to 1600 kW the units can pass through standard door openings and only require minimum floor space in the plant room.

Simplified electrical connections

  • Main disconnect switch with high trip capacity
  • Transformer to supply the integrated control circuit (400/24 V)

Simplified hydraulic connections

  • Victaulic connections on the evaporator and condenser
  • Practical reference marks for entering and leaving water connections
  • Possibility to reverse the heat exchanger water inlet and outlet at the factory
  • Possibilty to modify the number of heat exchanger passes

Fast commissioning

  • Systematic factory operation test before shipment
  • Quick-test function for step-by-step verification of the instruments, expansion devices and compressors.

Options

  • Unit supplied in two assembled parts - Facilitates installation in plant rooms with limited access for certain bigger sizes.
  • Medium-temperature/Low-temperature brine solution/ Light Brine solution
  • Evaporator with one pass / Condenser with one pass
  • Reversed evaporator / condenser water connections
  • Touch Pilot control, 7” user interface
  • Leak detection
