The Block 4.0 HMD Heat Manager

The Block 4.0 Heat Manager - bowl attachment for hookahs

Heat management devices (HMD) such as The Block 4.0 simplify heat management in hookah smoking and minimise the necessary charcoal consumption while maintaining or even improving performance. The heat manager is made of rustproof aluminium. It is provided with an anti-slip flange that allows it to sit securely on any suitable bowl.

Fit for popular large tobacco bowls

With a diameter of 74mm, the Smokebox is primarily suitable for large hookah heads with a correspondingly wide diameter and preferably a dedicated space for this type of accessory. Suitable bowls for The Block 4.0 are, among others, the Kaya Phunnel Deep Clay, Miray as well as silicone bowls with ceramic or fireclay phunnels. But it also fits easily on bowls of the Saphire Prime Edition, Oblako M and Cascade as well as Kalifa Phunnels.

The lower coal cup has 3 large slots for the supply of fresh air in the side area and a further 8 openings in the base to release the heated air towards the tobacco. The bottom area of the cup is criss-crossed by several grooves, which ensure that the coal does not lie flat in the cup, but that the air can circulate completely around it. This allows the coal to burn evenly. At just under 4.5 mm, the slots on the sides are high enough not to be covered by the tobacco bowl's rim area during use. This is the only way to keep the airflow unobstructed and regular.

Lid with exhaust function

The lid has 5 exhaust air openings. When the heat manager is placed on the tobacco bowl, the lid is usually not needed immediately. When the heat decreases, the lid is put on to retain the heat. Excess heat escapes through the exhaust openings to avoid the formation of heat peaks. This prevents the attachment from overheating and thus the tobacco from being burnt. By turning the lid, the size of the openings can be adjusted to suit individual needs. The handle of the lid has a heat-resistant coating of black plastic. The plastic handle makes it easier to operate the Heat Manager and reduces the risk of burns. The handle and lid form two separate components. Before using the heat manager, the handle must be screwed into the round opening provided in the lid.

Suitable hookah charcoal: shape, number and size

Only natural charcoal (e.g. based on coconut) is suitable for use with The Block. When using charcoal cubes, 2 pieces of hookah coal with a diameter of 26 mm are already sufficient for one session. Alternatively, 3 x 25 or 3 x 26 mm cubes can be used. Commercially available 1/4 or 1/3 coals also fit well in the cup and can be used for operation without hesitation.

Instructions for use from the manufacturer

Before first use, clean thoroughly to remove residues of dust and metal shavings. Caution - the edges of the milled openings can be sharp.

Please do not preheat the smokebox on the charcoal lighter/stove top. Aluminium can start to melt at high temperatures.
