ONMO heat manager — aluminium smokebox, two 27 mm coals for steadier flavour

What it is, why it helps, how it works: This is a heat management device (HMD) that sits on top of your bowl and replaces foil. Made from aluminium, it regulates how much heat your coals send into the tobacco so you get smoother flavour without harsh spikes. ONMO adds a diamond-profiled interior for airflow under the coals and a bar on the base so you can run it contactless, full contact or “bar contact” to fine-tune heat. If your bowl has a roughly 75 mm HMD rim, this will likely fit and give you more consistent sessions with less fuss.

What sets it apart

  • Even, stable heat because the diamond-profiled interior feeds air under the coals to keep them lit and prevent dead spots.
  • Versatile heat styles with the base bar: run distance, full contact or bar contact to match blonde or dark-leaf packs.
  • Dialled for 2 large cubes — comfortably fits two coals up to ~27 mm; wide upper lip lets you rest a third on the edge when needed.
  • Easy fit on HMD-ready bowls thanks to a ~75 mm base footprint that suits most modern phunnel/Egyptian rims.
  • Light, responsive build from aluminium (approx. 69 g) for quick heat adjustments and faster cool-downs between moves.

Fit & compatibility

Designed for most HMD-ready bowls with an inner rim around 75 mm. Works with popular phunnel and Egyptian profiles. If your bowl accepts a Lotus-style HMD, ONMO will generally sit the same way. For bowls, browse our curated phunnel selection.

How to dial it in

  • Use two natural coconut cubes (26–27 mm). Start “distance” (slight gap) for blonde leaf; move to bar/full contact for darker blends.
  • Vent/edge a third coal briefly on the rim to bump heat during the mid-session dip; return to two once flavour stabilises.
  • Rotate and tap ash every 6–8 minutes to keep the heat curve smooth.
  • If harsh, lift the lid (or crack the gap) for 10–15 sec, or slide back to bar/distance contact.

Craft & performance

Aluminium construction keeps response snappy: adjustments show up quickly in the bowl. The interior diamond profile improves airway response under the coals for cleaner flavour and steadier clouds, while the raised lip makes managing coal position safer.

Care & upkeep

  • Let it cool before rinsing; hand-wash with mild dish soap; avoid abrasives.
  • Do not preheat the HMD on a burner; always heat coals separately.
  • Dry fully before storage. For fresh, clean heat every time, see our quick HMD cleaning guide.

FAQ

  • Will it fit my bowl? If your bowl accepts a Lotus-style HMD and the inner rim is around 75 mm, you’re set.
  • How many coals? Run two 26–27 mm cubes for most mixes; rest a third on the rim to boost heat mid-session.
  • Why ONMO over foil? Cleaner flavour and steadier heat with less micro-management — and fewer burnt spots.
