Johnson Controls Mini 2-way VRF systems outdoor
units have a modular design and compact footprint,
choosing a Johnson Controls VRF system means easy
installation and commissioning. With multiple unit
connectivity, up to 9 indoor units can be connected to
one condensing unit and the system takes advantage
of building load diversity. Diversity ratios of 50% to
130% allow for a smaller outdoor unit. Johnson Con-
trols Mini 2-way outdoor units come in 2 sizes, 3 ton
and 4.4 ton.
