Bosch 48K BTU 21.7 SEER2 Gen 4 Wall Mount Mini Split 5-Zone Max Performance 25 ft Lineset 230V R454B 12+12+12+12+12

The Bosch Climate 5000 Gen 4 ductless mini split heat pump kit offers a powerful solution for efficient heating and cooling in up to five zones. Designed for homeowners seeking a high-performance system without the need for extensive ductwork, this versatile kit includes an outdoor condenser and five wall-mounted indoor air handlers, each capable of delivering precise temperature control.


Bosch Climate 5000 Gen 4 48,000 BTU Outdoor Condenser - R-454B | 230V BMS500-AAM048-1CSXHD

The BMS500-AAM048-1CSXHD outdoor condenser is engineered to deliver robust performance in a compact form factor. Built with R-454B refrigerant for eco-friendly operation and equipped with a continuously-variable inverter compressor, it ensures reliable heating down to -13°F and cooling up to 128°F.

Superior Heating & Cooling Performance

  • 21.7 SEER2: delivers strong seasonal cooling efficiency that helps trim energy costs through the summer months.
  • 11 HSPF2: provides efficient heat-pump warmth for cost-effective comfort when the temperature drops.
  • 11.85 EER2: holds solid efficiency under peak-load conditions on the hottest days of the year.
  • Cold-Weather Output: rated heating capacity of 48,500 BTU at 47F, 44,000 BTU at 17F, 47,000 BTU at 5F, with a COP of 2 at 5F for dependable heat as it gets cold.
  • ENERGY STAR Cold Climate: certified for reliable performance in genuinely cold climates, not just mild weather.
  • Wide Operating Range: engineered to cool and heat across a broad outdoor temperature range for year-round comfort.

Advanced Technology

  • Inverter Compressor: continuously varies its output to match demand instead of cycling fully on and off, saving energy and holding steady temperatures.
  • R-454B Refrigerant: uses an eco-friendly, low-GWP refrigerant that meets the latest environmental requirements.
  • A2L Safety Sensor: a factory-installed refrigerant sensor adds an extra layer of built-in safety.
  • AHRI Certified: performance ratings are independently verified, so you know exactly what you are buying.
  • Variable-Speed Operation: ramps smoothly to keep rooms at a consistent temperature while minimizing energy use.

Whisper-Quiet Operation

  • Whisper-Quiet: the inverter-driven condenser runs quietly for an unobtrusive presence outside your home.
  • Smooth Ramping: variable-speed startups avoid the loud kick-on of traditional single-stage units.
  • Compact Footprint: a compact outdoor unit fits neatly on patios, balconies, and tight side yards.
  • Low Vibration: the inverter design keeps outdoor operating noise and vibration to a minimum.

Durability & Long-Term Protection

  • Blue-Fin Coating: water-wicking blue-fin technology resists corrosion to extend the life of the coil.
  • Weather-Resistant Build: engineered to protect internal components against the elements year-round.
  • Pre-Charged Line Set: includes a 25 ft pre-charged line set that speeds up and simplifies professional installation.
  • Compact Install: the indoor and outdoor units connect through a small exterior wall opening.
  • No Ductwork: requires no ducting, making it ideal for additions, renovations, and enclosed spaces.

Warranty Coverage

  • 7-Year Parts: replacement-parts coverage for 7 years, extending to 10 years when you register the system.
  • 10-Year Compressor: a full decade of protection on the compressor, the heart of the system.
  • Professional Installation: warranty coverage requires professional installation for lasting reliability.

With its durable self-cleaning blue-fin technology, the outdoor unit requires minimal maintenance while providing consistent performance throughout extreme weather conditions. This robust condenser is essential for a seamless operation of the Bosch Climate 5000 Gen 4 system.
