Bosch 8733980437 48K Btu 4-zone Mini Split Kit

Product Description

The BOSCH 8733980437 is a complete 4-zone mini split system kit rated at 48000 BTU/h, designed for multi-room residential and light commercial cooling and heating applications. The kit includes four 12000 BTU/h indoor air handlers, one outdoor condensing unit, and four 25-foot line sets, providing everything needed for a full multi-zone installation. This is a factory-assembled kit that reduces the risk of component mismatch. Licensed HVAC technicians install this type of system where independent zone control across multiple rooms or areas is required.

This kit is suited for residential and light commercial applications where up to four separate zones need individual temperature control. Typical installations include multi-room homes, small office suites, or additions where extending existing ductwork is impractical. Each indoor unit operates as an independent zone, allowing occupants to set different temperatures in each area. The 25-foot line sets included are pre-selected to match the indoor and outdoor unit pairing in this kit configuration.
