Na Grani “On The Edge” Aluminium HMD — Open-top control, Lotus-rim fit

Na Grani aluminium HMD — open-top heat control for smoother flavour on phunnel bowls

What it is, why it helps, how it works: This is an open-top heat-management device (HMD) that sits on your bowl rim and holds your hot coals. By channelling heat evenly without foil, it keeps flavour steady and mess down. The lighter aluminium body reacts quickly to coal moves, so you can nudge heat up or down in seconds instead of fighting harsh spikes. Ideal for daily sessions when you want clean, consistent flavour with simple control.

What sets it apart

• Responsive heat curve from a lightweight aluminium body that warms fast and cools quickly when you adjust coals.
• Open-top control built for 2–3 × 26 mm cubes, so you can ramp or ease heat by adding, removing or edging a coal.
• Lotus-style rim fit on modern phunnel bowls (~72–76 mm typical), giving you a confident seat and even contact.
• Cleaner sessions with raised side ports that help keep ash off the mix and reduce harshness.
• Genuine Na Grani piece, supplied in a branded wooden box for tidy storage between sessions.

Fit & compatibility

Designed for modern phunnel bowls with a Lotus-style rim around the low-70 mm range. For bowl options, explore our curated Phunnel Bowls and pair with reliable 26 mm cubes from our charcoal range.

How to dial it in

• Start with 2 × 26 mm cubes inside the HMD; after 5–7 minutes add a 3rd if you want denser clouds.
• If notes get sharp, edge one coal half-in/half-out for 10–15 seconds; rotate coals every 6–8 minutes.
• Tap ash into the tray, not into the HMD, to keep airflow clear and flavour clean.

Craft & performance

The aluminium build gives a quick, predictable heat response and a forgiving flavour window. Draw stays open thanks to the ring-style design, and recovery after a purge or coal move is fast.

Care & upkeep

• Let it cool fully before cleaning; rinse with warm water and a drop of mild detergent; dry thoroughly.
• Avoid abrasive pads and harsh alkali cleaners to preserve the finish.
