AquaSnap®
30RBM 160-520

Air-Cooled Scroll Chillers

The Aquasnap (30RBM) version features a compact all-in-one package optimised for full-load applications where reduced investment cost (low Capex) is required. For cold or hot climates, the Aquasnap can be equipped with specific options with optional IP54 electrical box and cabinet fan to operate up to 52 °C outside air temperature.


Nominal cooling capacity 164-528 kW


The 30RBM Aquasnap liquid chillers are designed to meet current and future Ecodesign and F-Gas European regulation requirements in terms of energy efficiency and reduced CO2 emissions. They use the best technologies available today.

The Aquasnap versions can be equipped with an integrated hydronic module, limiting the installation to straight-forward operations like connection of the power supply and the chilled water supply and return piping (plug & play), within the dimensions of the standard unit.

Performance Features

  • The 30RBM Aquasnap liquid chillers are designed to meet current and future Ecodesign and F-Gas European regulation requirements in terms of energy efficiency and reduced CO2 emissions. They use the best technologies available today:
  • Micro-channel heat exchangers with new aluminum alloy, Novation®,
  • Low R410-A refrigerant charge below 0.14 kg/kW, through the use of Novation® micro-channel heat exchangers
  • Eurovent energy efficiency class A or B
  • Low-noise scroll compressors with low vibration level
  • Brazed plate heat exchangers with reduced water pressure drops.
  • Auto-adaptive microprocessor control
  • Optional Touch Pilot control with web connectivity possibilities and colour touch screen user display
  • Extra energy savings through multiple options: Direct expansion free cooling system on one or two circuits, hydronic free-cooling system, partial or total heat recovery.
  • With a length of approximately 4.8 m for 520 kW and a width of 2.25 m the units require minimum floor space

Product Features

  • Multiple scroll compressors equipped with a high efficiency motor that permit exact matching of the cooling capacity to the load
  • Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface (superheat control)
  • Condenser with high-efficiency aluminum micro channel heat exchangers, Novation® .
  • Low pressure drop brazed plate heat exchangers (pressure drops < 45 kPa at Eurovent conditions).
  • High unit full and part load energy efficiency and efficient design of the water side
  • Specific control functions to reduce unit cooling energy use during occupied and unoccupied periods
  • Greenspeed® variable-speed pump to reduce pumping energy use up to 2/3 (option recommended by Carrier)
  • Elimination of the energy losses caused by the water flow control valve by the electronic setting of the nominal water flow
  • Energy savings during stand-by periods or part-load operation by automatic water pump speed reduction.
  • Pump motor energy use varies as the cube of the speed so that only 40% speed reduction can reduce energy consumption by 80%
  • Improved unit part-load performance (SEER increased SEER value with variable water flow following EN14825).
  • Condenser coils in V-shape with an open angle, allowing quieter air flow across the coil
  • Low-noise 4th generation Flying Bird fans, made of a composite material (Carrier patent)
  • Rigid fan installation for reduced noise (Carrier patent).

Maintenance Features

  • Fast diagnosis of possible incidents and their history via the control
  • R-410A refrigerant is easier to use than other refrigerant blends
  • Over 15 diagnostic functions
  • Permanently lubricated fan motor bearings
  • Compressor suction service valves (option)
  • Quick-test function for step-by-step verification of the instruments, electrical components and motors
  • Service contract available
  • Qualified Carrier service people for refrigerant servicing

Installation Features

  • The Aquasnap units are designed to offer compact dimensions for easy installation.
  • With a length of approximately 4.8 m for 520 kW and a width of 2.25 m the units require minimum floor space.
  • Single or dual pump (option) with operating time balancing and automatic changeover to the back-up pump if a fault develops
  • Water filter protecting the water pump against circulating debris
  • Pressure transducers for direct numerical display of the water flow rate and water pressures
  • Thermal insulation and frost protection down to -20 °C, using an electric resistance heater (option)
  • High-capacity membrane expansion tank (option).
  • Integrated hydronic module with Greenspeed® variable speed pump (option)
  • Easy and fast electronic setting of the nominal water flow at unit commissioning thus eliminating the water flow control valve adjustment
  • Automatic control of the pump speed based on constant speed, constant pressure difference or constant temperature difference.
  • A single power supply point without neutral
  • Main disconnect switch with high trip capacity
  • 24 V control circuit without risk from a transformer included.
  • Fast unit commissioning with systematic factory test before shipment
  • Quick-test function for step-by-step verification of the instruments, electrical components and motor.

Standard Warranty

  • One year from start-up or 18 months from shipment
