Our Commitment

Our commitment is to save the earth and increase energy savings with digital technology that provides superior control and cost efficiency with the DC invertor compressor. Super-accurate rotation of an environmentally sustainable compressor results in power savings of up to 50%* (compared to AC Fixed Speed compressors) and quieter operation.

With the fast increasing waste stream, we aim to minimize the impact of electronic goods on the environment. Such inspiration helps us to limit the quantity of waste stream infiltrating into the final disposal by applying the recyclable plastics.
