Pentair’s Proair now with IP66

The Proair series stainless-steel air conditioners can be used in indoor applications, the company notes. Optional components such as heaters can be added to allow their use in outdoor applications as well.
These air conditioners feature R134a refrigerant and compressors with an operating temperature range of -40 to +55°C. The models are available with various operating voltages (115V, 230V and 460V) and cooling capacities (400W to 2000W).
The optimal cooling capacity is supported by washable, reusable aluminum filters, Pentair notes, and the fins of the condenser can be cleaned while the unit remains fitted in its housing.
By equipping these units with an optional “malfunction package” early warnings can be issued in the event of a fan failure or blocked filter as well, Pentair says.
