Air cooled chiller/heat pump

Introduction to the rangeNEOSYS™ is providing chilled and hot water for all applications with fan coils, chilled beams, air handling units, floor heating or chilled ceiling use in office buildings, hotels, administrations, ...

Sustainable performanceExtended qualification tests (vibration tests, run tests, field tests) to ensure superior reliability. High efficiency aluminium micro channel heat exchanger (MCHX) with improved corrosion resistance for moderate marine or urban applications (Cooling only version).Specific MCHX coil design with high mechanical fin resistance that offers easy cleaning with high pressure air or water washers for extended life cycle.Compressor and hydraulic enclosure, V-coil design to protect the unit against climatic aggressions (e.g. UV light, hail). Exclusive Compliant Scroll® compressor design with both axial and radial compliance to increase compressor operation tolerance of liquid refrigerant, substantially improving durability and reliability.Exclusive fan design with hybrid ceramic bearings to maximise the service-life of motors and to reduce noise level.

Quiet performanceUnique design with compressors, pump(s) and fan acoustic enclosure to reduce radiated noise emissions.Variable speed driven fans using external rotor technology associated with high performance aluminium fan blades of the latest generation.Elimination of intrusive fan start/stop noise that is irritating to the human ear. Active Acoustic Attenuation System™ (A3) to meet changing building load requirements while automatically adjusting the air flow to meet night and day sound level constraints (Time schedule with 4 time zones per day).

Start-up and service performanceComplete hydraulic module with single or twin, low or high pressure pump (options) that includes all necessary equipment for quick connection: pump(s), regulating valve, expansion vessel with pressure gauge, pressure tapping points, water filter, air vent, pressure relief valve and victaulic connections. 400V, 50 Hz, 3 phases power supply (without neutral) with a single point of power connection. Main on/off switch included as standard.Air spring powered Butterfly electrical panel™ with top opening provding protection to service engineers against rain or snow during commissioning and maintenance operations.

Energy performanceHigh Seasonal Energy Efficiency Ratio in cooling and heating mode (ESEER above 4; EER up to 2,9; COP up to 3,2) for improved energy consumption all around the yearAluminium micro channel heat exchanger offering outstanding system efficiency (Cooling only version).R410A refrigerant for optimized system performance.Energy savings due to lower system minimum water content buffer tank elimination reducing the time to reach setpoint.

Architectural integrationState of the art design with hidden compressors, fans and pump for perfect architectural integration. Flat top, aesthetic grilles, very low unit height (< 2m) for discrete installation on a roof reducing the requirement of costly cladding solutions around the unit.
