This is a new backflow prevention device, which can be used to fill:

• Heating systems

• Chilled water systems
• Cooling circuits
• Industrial processes

Filling loops for non-house applications must not be used at all.  Autofill does not require a filling loop.  There is no tank or pump (except model AFP) and replaces traditional pressurisation units.
