19 PV - Magnetic Bearing Oil

Cooling capacity: 100-350TR

19 PV – Magnetic Bearing Oil
  • 11.2 IPLV
  • 6.3 COP
  • 73dB(A) sound level
  • 1.1m min. width



With its excellent acoustic performance down to 73dBA at a distance of 1.0 meter, 19PV is an ideal choice for sound sensitive environment. The factory-mounted acoustic treatments of 19PV compressor help to save the expenditure on sound treatments necessary for noisy conventional compressor.


The 19PV is for air conditioning cooling application, as standard the unit can provide an evaporator leaving water temperature down to 3.3 .

  • The cast aluminum casing and high strength thermoplastic electronic enclosure effectively insulate the compressor which reduces the noise generated within.
  • The compressor’s rotating parts are completely levitated by electromagnetic force which results in reduced friction and vibration, and hence lower operational sound.
  • Greenspeed variable speed control adaptively turns down impeller speed at part load for better acoustic performance.
  • 19PV chillers meet 18001 standard recommended by Occupational Health and Safety Advisory Services (OHSAS).
  • Exclusive magnetic bearing two stages compressors
  • Low-noise and less vibration through magnetic levitation
  • Oil-free
  • Extremely efficient mechanically cleanable flooded evaporators
  • Environment stewardship refrigerant HFC-134a
  • Electrical power and remote control cabinet
  • 380/400V-3Ph-50Hz and 380/460V-3Ph-60Hz general power supply (±10%)
  • New Touch Pilot control system PIC5+
  • EMC/EMI filter meets IEC61800 C3 standard
  • Circuit break interlock with high pressure switch

The latest generation AquaEdge 19PV magnetic bearing variable speed oil free centrifugal chillers are the perfect solution for commercial and industrial applications in the Office, Hotel, Healthcare, Shopping mall, Collective housing, Industry, Data center and Metro line station where installers, consultants and building owners require maximum quality and optimal performances, especially at part load. They are designed to meet current and future requirements in terms of energy efficiency, operation cost ,versatility and compactness.

The 19PV uses the most reliable technologies available today which guarantees compliance with the demanding requirements for high energy efficiency and CO2 reduction to comply with the various applicable Asian directives and regulations.

High efficiency

The 19PV is specifically designed for high performance both at full load and at part load, exceptional IPLV values set new benchmark for low energy consumption utilizing magnetic bearings, two stage centrifugal compression, variable speed permanent magnet motor and intelligent electronic controls.

  • High speed direct-driven motor and shaft reduces the mechanical loss by 75% by eliminating the gear system
  • The permanent-magnet synchronous motor powered by pulse-width modulation outperforms conventional motors with respect to efficiency, and therefore leads to distinguished chiller efficiency at full load and part load.
  • The adoption of oil-free system boosts the operational efficiency by eliminating the inevitable oil contamination in the refrigerant and heat exchanger.
  • Flooded multi-pipe evaporator and condenser for increased heat exchange efficiency.
  • High performance copper tube bundle with internal and external grooves along with enhanced fins improves chiller efficiency by reducing the heat transfer resistance.
  • The single refrigerant circuit design optimizes the heat exchange process, particularly at part load.
  • Electronic expansion device permits operation at a lower condensing pressure and improves utilization of the evaporator heat exchange surface.
  • Part Load Efficiency (AHRI IP) Load 25% 50% 75% 100%
  • COP (kW/kW) 16.0
