CAPS Australia Harsh Environment Efficient VFD Option (HEEVO)

In harsh mine site and construction environments, most variable-speed compressors available in the Australian marketplace may struggle with high heat, humidity and dust levels. The result can be frequent breakdowns or shutdowns, costly component failures or expensive preventative maintenance.

CAPS Australia has released its Harsh Environment Efficient VFD Option (HEEVO) to suit Ingersoll Rand compressors from 11 to 350 kW. The HEEVO is suitable for mining, timber and other rugged industries where high dust loads are common. The option is also appropriate for applications operating in offshore, marine and similar environments where humidity is the main concern.

The sensitive nature of variable speed drive compressors means that normally they are more at home in a clean plant room than in a harsh environment where reliability is the top priority. Achieving reliability normally means compromising on efficiency.

The HEEVO enhances the overall IP rating of the compressor’s motor and electrical components so that there is protection against entry of dust that is in sufficient quantity to interfere with satisfactory operation of equipment, and protection against extreme humidity, heavy seas and jets of water from all practical directions.
