Product / MDH
Halton ModularChef is a low profile and freestanding Capture Jet™ hood. Its design allows for connecting it to the ventilation ductwork on the back, the side or from the bottom.
Up to 40% reduction in exhaust airflow rates compared to traditional suspended hoods. Here is the first benefit that distinguishes ModularChef hood. The downdraft exhaust plenum it is equipped with can’t be closer to the cooking appliances and the heat, smoke, steam, grease and other pollutants they release. This proximity combined with the Capture Jet™ technology’s action and the full height sides makes it less airflow-consuming. ModularChef hence achieves massive savings on the ventilation energy bill.
Such exhaust airflow reduction also means ModularChef is the ideal hood to be used with PST PolluStop exhaust units or RAH RecoAir recirculating units by increasing their global cost effectivity. An asset to establish restaurants in previously unfeasible locations.
The Capture Jet™ technology enables the hood’s front to be backward regarding the cooking appliances. The Indoor Air Quality is kept at the highest level while the noise levels are reduced. The ergonomics are hence close to that of a hood installed at the regular height, while the comfort and productivity are even better.
Lastly, ModularChef is a solution especially suitable to establishing kitchens in low height rooms. The numerous connection possibilities to the ductwork combined with the reduction of its section greatly facilitates the path of the ductwork to outside in the most challenging situations.
ModularChef finds also its place in kitchens with normal ceiling heights, With the additional benefit of promoting the feeling of openness. Its compact design makes it also especially suitable to front and show cooking concepts. It is an aesthetic solution that makes the chefs and guests closer.
ModularChef integrates the cooking appliances power supplies. It modular design enables whatever configuration, even for long cooking lines.

More about the main embedded technologies
About Capture Jet™ technology
The Capture Jet™ technology ensures the grease, smoke and the other pollutants released by the cooking appliances are captured with the lowest possible airflow rate. In the majority of cases, it pays back upon start-up of the kitchen.
The energy savings directly contribute to your profitability while the staff benefits from improved working conditions.
- Up to 55% reduction in exhaust airflow rates compared to traditional suction only hoods.
- No compromise on the smoke and heat capture with reduced airflow rates while maintaining the air quality.
- Significant energy savings for the cooling/heating make-up air systems (less air out, less air in!).
- Reduced infrastructure costs on the smaller duct and fan system, saving on the capital cost of the installation.
- No specific duct required for Capture Jet installation, reducing installation costs.
- Improved working conditions for the staff: less drafts inside the kitchen and reduced noise levels due to the airflow rate reduction.

3 – Junction module
Up to 2450 mm length, the ModularChef hood is equipped with a unique junction module (3) which integrates also a grease collector. The module can be located either on the left or the right of the active module (2).
Above 2450 mm, the junction module is used to assemble two active modules together. The grease collector is then common to the two sections. Alternatively, each active module can also be equipped with its own junction module.
Admissible and calculated airflows
(1) QE min = 505 m³/h/KSA @ ΔP T.A.B. = 59 Pa
QE max = 786 m³/h/KSA @ ΔP T.A.B. = 120 Pa
The exhaust airflow rates of Halton’s Capture Jet™ hoods are determined with a EN 16282-1(1) based calculation method. It relies on the evaluation of the convective volumes (air mixed with heat, steam, grease, smoke and other pollutants) generated by the cooking appliances, depending on the energy used and their installation conditions (central, on a wall, in an angle).
The air volume required to remove the convective loads is then calculated depending on:
– The hood or ventilated ceiling installation conditions;
– The makeup-air strategy (mixing or displacement);
– The hood or ventilated ceiling capture efficiency according to ASTM 1704-12 standard.
On that base, MDH ModularChef hood reduces the exhaust airflow rates by up to 55% compared to traditional hoods.

Combination with RAH RecoAir recirculating units
RecoAir is a range of advanced and cost-effective recirculating unit that enables setting up a kitchen in a room which doesn’t have an exhaust ductwork available. They work at the heart of a kitchen ventilation system serving electric catering equipment.
The very low airflow levels required by ModularChef hoods make them an ideal capture solution for RecoAir units. They allows for reducing the units’ size to improve more the cost effectiveness.
Cooling down the return air
After Reco-Air unit, the return air is a similar temperature to that extracted and needs to be cooled down before being blown back into the kitchen.
– Spot cooling i.e. fan coil units within the kitchen space;
– Chilled water coil or DX refrigerant cooling coil installed on the return air ductwork etc…
