The condensing unit design features separate air flow and mechanical compartments, this
improves over all air flow volume and improves frost resistance with MHIs unique 4-sided
heat exchanger design providing a larger surface area that further increases efficiency.
Having separate air flow and mechanical compartments also means high protection of
mechanical and electronic components in extreme conditions, while making service
maintenance easy with simple access to serviceable parts. Noise levels are reduced, footprint
is reduced and more piping configurations are possible. (frontside, backside, etc).
The vertical fan configuration also allows ducting of the discharge air with 50Pa static
pressure in standard conditions. Outdoor units can then be located in infernal plant rooms,
with discharge air ducted te outside through a louvre panel.
