ONMO HMD Black Edition - Premium Heat Management Device

ONMO heat-management device — black sandblasted aluminium, 75 mm base for cleaner flavour

What it is, why it helps, how it works: An HMD sits on top of your hookah bowl and holds your hot coals. Instead of using foil, the device lets heat flow in a controlled way so your tobacco warms evenly. That means fewer harsh spikes, steadier flavour and less ash falling into your bowl. The ONMO Black Edition is an open-top, sandblasted aluminium unit with a 75 mm base that suits most bowls and makes heat control easy—just move or rotate your coals.

What sets it apart

• Even heat, fewer hot spots — perforated top and inner diffuser pattern spread heat across the pack for smooth, consistent pulls.
• Fast, simple control — lid-less design with wide ventilation slots for quick coal rotations and easy ash taps mid-session.
• Durable sandblasted finish — matte black exterior resists fingerprints and everyday handling.
• Balanced feel — light 69 g body sits securely without weighing down your bowl.
• Flexible technique — works with distance, full-contact or bar-contact setups so you can tune heat to your tobacco and coal strength.

Fit & compatibility

Base diameter is 7.5 cm. It fits most standard phunnel and traditional bowls with a flat rim and space for a ~75 mm HMD. Very small “mini” bowls or extra-wide rims may not suit. If your bowl comfortably seats a 7.5 cm base, you’re good.

How to dial it in

• Fully light your coals. Start by placing them around the edge; pull for 1–2 minutes.
• If flavour is thin, nudge coals slightly inward. If it’s harsh, move them back to the edge.
• Tap off ash every few minutes to keep airflow clear; rotate coals to refresh heat.

Craft & performance

Machined from premium aluminium with a sandblasted black finish. The top plate’s circular channels and perimeter holes regulate airflow, while the inner diffuser pattern spreads heat across the surface. Open-top form keeps temperature adjustments immediate and intuitive.

Care & upkeep

• Let the HMD cool naturally—do not quench in water.
• Brush out ash, then wash with warm water and mild detergent; avoid abrasive pads to preserve the finish.
• Dry fully before storage.
