Flamco

Purpose-built for EN 12828 heating and chilled-water systems, this multifunction sealed-system unit combines automatic expansion control, pressurisation, deaeration and make-up in a single package.

A pressure-step degassing process—using a controlled pressure drop and patented PALL-ring media—removes dissolved gases even at equilibrium. A replaceable butyl bladder stores the expansion fluid at atmospheric pressure. Supplied with Flexvent Super, height-adjustable feet and a weight-capacity sensor.

• All-in-one functionality — expansion, pressurisation, deaeration and make-up
• Pressure-step deaeration with PALL-ring technology
• Replaceable butyl bladder — easy maintenance and long service life
• Delivered complete — Flexvent Super, adjustable feet, weight-capacity sensor

Designed for commercial, industrial and residential sealed LPHW/CHW installations requiring efficient air removal and stable operating pressures.
