Mitsubishi Heavy Industries has made a giant leap forward in air conditioning and heat pump technology, with the latest introduction of high performance standard range "ZSP" wall mounted air conditioning systems. The NEW ADVANCED SRK Wall Mounted Indoor Units have a new ‘smooth line’ design of fascia, which has a lower profile flatter appearance, and is far more easy to keep clean. The SRK now includes the Mitsubishi innovative NATURAL ENZYME FILTER which destroys funghi, bacteria and viruses. This, combined with the main Photocatalytic Washable Deodorizing Filter, provides healthy clean air for the occupants. R32 is the next generation refrigerant that boasts nearly 70% lower Global Warming Potential Rate than R410A. Due to its superior qualities R32 offers amazing energy efficiency benefits. It has a potential refrigerating effect 1.5 times that of R410A meaning it needs less energy to achieve the desired temperature and requires less refrigerant volume to operate
