New range of Air Flux 6300 air conditioning with heat recovery from Bosch Thermotechnologie

Dedicated to hotels, offices, nursing homes, clinics, high-rise buildings, fitness rooms, shops, etc., it stands out with many advantages:

• extended powers with 6 monobloc models from 22 kW to 50 kW and cascades of 3 units up to 150 kW,
• operating ranges down to - 25 ° C in hot mode, and + 52 ° C in cooling mode,
• opening to high temperature domestic hot water up to 80 ° C, with the new AF-HB hydraulic module, the most compact and light on the market,
• high performance in reversible, heat recovery and DHW modes (SEER up to 7,26 and SCOP up to 4,59),
• the possibility of connecting up to 36 indoor units to a single outdoor unit,
• uniformity of the range in terms of design, installation, adjustments, settings and maintenance, a guarantee of optimal comfort for the installer,
• a EUROVENT certified range.

The latest addition to the Bosch VRF Air Flux range, the Air Flux 6300 outdoor units make it possible to offer an ever more complete offer. They complement the Mini VRF MDCI and VRF Air Flux 5300 reversible outdoor units (between 7 kW and 270 kW). Air Flux 6300 is compatible with all Air Flux indoor units and accessories. 1, 2 or 4-way cassettes, compact ducted high or medium static pressure, consoles, wall ..., a whole range of indoor units is available to adapt to all collective and tertiary environments. The individual and centralized touch-sensitive controls make it possible to control the system completely and easily. Connection to various Technical Management systems is also possible via communication gateways.

A comfortable and energy efficient solution

This range offers simultaneous cooling and heating operation in a single system. Energy and heat recovery is achieved by transferring the heat extracted from certain rooms to areas in need of heating. It is practical and essential for the comfort of occupants, particularly in mid-season, when the north facades of a building may need heating, while the south-facing rooms are cooled.

The [+]: new SBOX AF-SB distribution boxes

SBOX AF-SB distribution boxes facilitate the
operation of the energy recovery system. The box controls each group of indoor units (up to 12 per SBOX), in order to simultaneously obtain heating and cooling mode in a system regulated by a SBOX box. Indoor units connected to the same SBOX box can operate independently, in cooling or heating mode. A guarantee of safety, a box continuously monitors the quantity of fluid per part, and ensures the safety required by standard EN378, in particular with regard to the detection of fluid leaks.

The sound level of the units can be lowered from 4 dB (A) to 8 dB (A), by adjusting the speed of the fans and the frequency of the compressors. Six “Silence” programs can be configured, an additional source of comfort that promotes concentration and well-being at work.

When Bosch Thermotechnology expands the range of possibilities

Compatible with the new Air Flux 6300 outdoor units, the new AF-HB hydraulic module ensures the production of Hot Water. It offers a hot water production temperature range from 25 ° C to 80 ° C (nominal power of 14 kW). Thanks to the positioning of the module upstream of the distribution boxes (SBOX), the number of indoor units after the SBOXes can be increased as needed, and the expansion reaches up to 200% of the total power of the outdoor unit. Its compactness (80 cm high) and lightness (58 kg) facilitate installation and allow a discreet layout. Another advantage is that it can also be used for heating: underfloor heating, radiators and fan coils. On a daily basis, its functions are numerous: thermal disinfection, holidays, weekly programming, Silence mode ... Several hydraulic modules can be installed in cascade to multiply the available DHW power!

A compendium of technology

The Air Flux 6300 heat recovery range features a new steam injection compressor that optimizes heating performance. It guarantees stable operation down to - 25 ° C as well as optimized sub-cooling. It offers a frequency range up to 140 Hz, and a faster and more efficient temperature rise at part load (from 15 Hz). In case of cascaded units, this technology provides efficient balancing between compressors. The brushless motor reduces friction and improves efficiency at low and partial loads, as well as overall equipment life.

Guarantee

This range is guaranteed for 5 parts for all spare parts and 5 years for compressors. If commissioning is carried out and validated by the Supplier's Manufacturer After-Sales Service, labor is included for the first two years.
