Engineered for potable and general water services, the Flamco Airfix D-E Expansion Vessel uses a full flow-through construction to prevent stagnation and support hygienic, high-quality water delivery.

A replaceable butyl bladder (DIN 4807/5) is formulated to add no colour, odour or taste, while a coated two-way system connection ensures complete vessel flow-through with low pressure drop. The Airfix D-E includes a pressure gauge with blow-back protection, nitrogen pre-charge for long pre-pressure retention, and an anti-oxidation coating on the inside of the connection flange.

• Full flow-through design to minimise bacterial growth
• Potable-safe bladder — no impact on taste, colour or odour
• Nitrogen pre-charge for longer pressure stability
• Coated flange & two-way connection to prevent oxidation and ensure flushing

Built for oxygen-rich, non-mains water duties, the Flamco Airfix D-E-B Expansion Vessel serves domestic, process and firefighting installations that require dependable thermal expansion control.

A replaceable butyl bladder (DIN 4807/5) preserves water quality with no added colour, odour or taste, while a nitrogen pre-charge extends pressure stability. The single threaded coated steel connection is a non-flow-through design, and the connection flange's special coating helps prevent oxidation.

• Potable-safe bladder formulation for neutral taste/odour/colour
• Nitrogen pre-charge for longer pre-pressure retention
• Non-flow-through single threaded coated steel connection
• Anti-oxidation coated flange for durability

Purpose-built for heat pump systems and sealed heating circuits, the Flextherm PS Thermal Storage Buffer stores heated water to stabilise flow, smooth demand and cut compressor cycling.

Floor-standing steel construction with 90° opposed connections allows corner placement for a smaller footprint. Models up to 2000 Ltrs include height-adjustable feet for accurate levelling. Four G½" temperature sensor ports support precise control. Maximum operating temperature 95 °C.

• Heat-pump friendly: reduces start/stop frequency
• Compact install: 90° connections suit corner mounting
• Scalable: link multiple buffers for higher volume
• Serviceable: adjustable feet (≤ 2000 Ltrs) for easy levelling

Note: this PS variant is typically used for heating; for chilled applications with factory insulation specify Flextherm PSK.
