Project Summary

Improving vacuum collection systems reliability by up to 70%.

HIFraser was awarded the task of assisting the supermarkets in handling waste water generated by refrigerated and back of house areas. The project included a new vacuum collection system and vacuum condensate risers with EVAC components.

Through our innovative approach and robust equipment, we were able to successfully deliver a system to collect and transport the condensate through overhead piping to our centralised vacuum station installed in the back of house areas.



Victorian Supermarket
