Dimensions are the injector. The control panel is a separate wall-mounted enclosure with mains lead, on/off and ozone indicators, fuse holder and monitor bypass socket. Supplied with power lead and fused 3-pin plug, 6mm clear tube with clips, and push-on pitot tubes. Duct connection 100mm circular. Electrical supply 240V, 1-ph, one supply per injector. Optional external ozone sensor: 200L x 150W x 95H, weatherproof cabinet, detection level adjustable to meet local guidelines.

Understanding System Performance in Real Applications

How it's works

Control happens inside the duct. A variable air pressure switch in the control panel samples extract pressure through a 6 mm tube and holds the air-to-ozone ratio as the cooking load changes. Concentration stays high enough to break down the odour compounds without running the injectors harder than the airflow needs. The same switch proves airflow, so the injectors cannot run while the extract system is off.

Ozone is generated by corona discharge from ambient air. The discharge splits oxygen molecules into single atoms, and those atoms bind to other oxygen molecules to form ozone. It is injected into the canopy plenum or the first length of duct, where it oxidises the compounds carrying the cooking odour, so the smell does not reappear further down the extract.

Where a site needs the discharge itself monitored, the EXM range adds a second stage of control at the end of the extract.

One change worth knowing about: your draft says "odour particulate", but the compounds that carry cooking smell are gaseous, which is the whole reason grease filtration doesn't touch them. Your own brochure makes that point on the odour control spread, so I've used "odour compounds" in both to keep the two consistent. Say if you'd rather keep the original wording.

EXS Ozone Odour Control For Commercial Kitchens

- Notes

on

Application

Output controlled from the air pressure switch, which holds the air-to-ozone ratio as the cooking load changes

Holds the correct ozone concentration across airflows from 0.9 to 7.2 m³/s (3,240 to 25,920 m³/h)

Ozone injected at the earliest point in the system, which keeps dwell times low

Delivered to multiple points to suit the system (plenum, duct before or after the fan, inline with filtration), with further injectors added without redesign

Power drawn only when injection is called for, which keeps capital and running costs low

Straightforward retrofit into existing ductwork, with the control panel sited away from the injectors where it can be read easily

Frequently Asked Questions

Frequently Asked Questions

Is the EXS200 or EXS400 suitable for my type of commercial kitchen?

Teal arrow pointing right, indicating direction or next step.

It suits kitchens with a varying load, which covers most restaurants, hotels and pub kitchens where the extract runs all day but only cooks hard at service. Up to 1.9 m3/s takes the EXS200 and up to 3.8 m3/s takes the EXS400. Above that, more injectors run from the same panel.

Can the EXS200 or EXS400 be used in non-kitchen environments such as factories or industrial premises?
