HIFraser supply the EVAC Horizon collection units to the Australian building sector.

EVAC’s Horizon vacuum drainage system is an efficient, reliable and compact solution for supermarkets. Its capacity allows for easy and quick relocation of complete departments of chilled cabinets or installation and removal of existing medium temperature or frozen cases.

One of the key advantages the system provides is the flexibility to overcome traditional gravity construction obstacles within any project. Other benefits of the unit include:

  • Compact design
  • High reliability with low maintenance requirements
  • Quiet operation
  • Continuous operation, even during the discharge process
  • Construction flexibility
  • Cost effective

The EVAC Horizon unit comprises:

  • Control panel
  • Two or three liquid-ring vacuum pumps with rotary displacement
  • Vacuum pump cooling system using recirculating water
  • Vacuum volume tank of 567 litre
  • Two wastewater collection tanks of 151 litres each
  • Valves and controls

The liquid-ring vacuum pumps generate a vacuum by forming a sealing ring of water. The vacuum collection unit uses a freshwater connection in conjunction with a re-circulating water reservoir to supply the liquid-ring pumps with the correct amount of sealing fluids. The collection tanks receive all wastewater and discharge it into the building’s sewer system. The tanks operate independently and are controlled by high-level switches.

HIFraser also supply spare parts and service all EVAC equipment.
