Unique patented technology

With its Cleaning-Free Technology, Mitsubishi Electric is offering a unique system for the power inverters of performance classes RP35-71 for the replacement old air conditioners with new ones – regardless of whether R22 or R407C is used as the refrigerant.

Advantages ...

The pipe already installed in the building can be re-used, so only the indoor and outdoor units have to be replaced – no need for costly and time-consuming installation of the refrigerant pipe.

… for customers:

– Reduces installation time.
– Reduces installation costs.

… für for installers:

– More competitive thanks to low-cost offers
– No pipe dimensioning for refrigerant R410A
– No need to flush existing pipes

How is this possible?

Mitsubishi Electric has developed a special refrigerant oil, known as HAB (Hard Alkyl Benzene), for efficient lubrication of the compressor - despite contamination by mineral oils as on old R22 systems or by ester oils on R407C/R410A systems.

Quick and inexpensive

You can thus modernize a faulty or outdated air conditioning system much faster and much less expensively - and create a more efficient and quieter air conditioning installation. On the larger power inverters, RP100-250, special carbon filters keep the existing pipes clean.
