Range
The range is available in 2 efficiency levels:
- 30XBE standard unit with variable-speed AC fan motors
- 30XBP premium unit - equipped with EC fans to improve both the full load and part load energy efficiency
Features & Benefits
- Discharge dampers integrated in the oil separator (Carrier patent)
- Silencer on the economiser return line
- Compressor and oil separator acoustic enclosure, reducing radiated noise (option)
- Condenser coils in wide angle V configuration, allowing quieter air flow across the coil
- Low-noise 6th generation Flying Bird™ fans, made of a composite material (Carrier patent), are now even quieter and do not generate intrusive low-frequency noise
- Inverter driven EC fans on 30XBP version eliminate start stop noise during part load operation
- Rigid fan mounting preventing start-up noise (Carrier patent)
- Integrated hydraulic module (option)
- Simplified electrical connections
- Fast commissioning
- R-134a refrigerant
- 40% reduction in the refrigerant charge through the use of micro-channel heat exchangers
- Leak-tight refrigerant circuit
- Industrial-type screw compressors with oversize bearings and motor cooled by suction gas
- Easily accessible compressor components minimising downtime
- Novation® aluminium micro-channel heat exchangers (MCHE) with high corrosion resistance
- Thermal insulation with aluminium sheet finish (option) on evaporator, for improved resistance to mechanical and UV damage
- Auto-adaptive control
- Exceptional endurance tests
- Equipped with bearings with oversized rollers, oil pressure lubricated for reliable and durable operation, even at maximum load
- Optimal adjustment of the compressor cooling capacity
- If a fault occurs, the compressor does not switch off, but continues operation with a 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 minimises the amount of oil in circulation in the refrigerant circuit and redirects it to the compressor function
