INVI - Scalar - HMD

The INVI Scalar HMD is a sandblasted aluminium heat management device with a removable lid in silver/grey. It measures 7.5 cm in diameter, is around 4.5 cm tall and takes three 26 mm coals at the start. The charcoal sits in the HMD instead of on aluminium foil.

Lid, slots and nubs

You control the heat via the removable lid. Slots built into the wall provide air circulation. Rounded nubs on the underside are meant to let the charcoal burn evenly.

Aluminium: fast and forgiving

Aluminium reacts faster to changes than stainless steel, does not absorb the heat excessively and releases it again more quickly. Mistakes in heat management are therefore easier to correct, which makes the HMD practical for beginners.

Dimensions

• Total diameter: 7.5 cm
• Total height: approx. 4.5 cm, without lid 3 cm
• Inner diameter of the anti-slip ring at the bottom: approx. 6.8 cm
• Inner diameter of the container at the top: approx. 6.9 cm

How to use the HMD

1. Pack the tobacco loosely into the bowl and do not press it down.
2. Put the HMD on the bowl; the ring at the bottom keeps it in place.
3. Place up to three well-glowing 26 mm coals inside and put on the lid.
4. Heat up for a few minutes, then adjust the heat via the lid and the number of coals.

Care and note

Do not preheat the HMD directly on the charcoal burner. Aluminium can melt at extremely high temperatures. Let it cool down completely after the session before you clean it.

Frequently asked questions

How many coals fit inside?

Three 26 mm coals at the start.

Does the HMD fit my bowl?

The listed compatibility for the HMD is standard. What matters is the rim diameter of your bowl; the ring at the bottom has an inner diameter of approx. 6.8 cm.

May I preheat the HMD on the charcoal burner?

No. Aluminium can melt at very high temperatures, so only place the coals in the HMD.
