Vacuum drainage systems for condensate utilise vacuum pressure for the collection, conveyance and disposal of refrigeration and HVAC condensate through a piping network that can be routed vertically and via the ceiling space.
Vacuum drainage systems work in concert with the new “open” architectural store environment where electrical and refrigeration services are brought to display cases from overhead. Drainage can now follow these services, allowing for unprecedented flexibility in store layout.
Labour and material costs are reduced since the installation is generally above ground and smaller diameter piping is used. On renovation work, the savings can be substantial depending on the size of the existing facility and the length and depth of trenching required for gravity waste pipe tie-in. Typical savings are 30% and in some cases much higher.
Because trenching is eliminated, store remodel activities are less expensive, safer, more sanitary, and take less time. Vacuum drainage systems are also completely adaptable to merchandising changes and can easily accommodate seasonal display requirements.
Vacuum drainage systems allow existing buildings with limited drainage to be developed for supermarket use when traditional trenching and underground piping upgrades are cost prohibitive because of site or structural conditions such as post tension slab, bed rock, asbestos, high water tables, etc.
