We are able to investigate the performance of the refrigeration system and advise on means of reducing power usage, improving compressor optimisation or just in removing bottle-necks in the plant to allow them to operate to their full potential.


Our clients include Alliance Group Ltd, Silver Fern Farms Ltd, Prime Range Meats Ltd and Cold Storage Nelson to name a few.
