INDOOR INSTALLATION
The machines are designed for indoor installation.
DESIGNED FOR INSTALLATION IN PARALLEL MAGNETIC LEVITATION CENTRIFUGAL COMPRESSOR
The TURBO FL liquid chillers are equipped with two-stage centrifugal
compressor with variable speed, which is able to follow punctually plant demands, obtaining values of energy efficiency ratio (EER) growing in  a narrowing of the cooling load. The compressors of the TURBO FL liquid chillers are equipped with magnetic levitation oil-free bearings which compared to traditional ball bearings, completely eliminate all the maintenance procedures of lubrication.
