Halton Foodservice has announced significant upgrades to its Reactocell ultraviolet air treatment cassette, which integrates into ventilation canopies to remove and neutralise grease vapours and small particles from kitchen extract air. Upgraded elements range from new ‘plug and play’ controls through to increased treatment capacity, longer life lamp and reduced cost of ownership.

Reactocell’s new UV control system features ‘plug and play’ operability to simplify installation and commissioning. Each controller automatically checks safety features (door and filters in place, airflows acceptable) before energising the UV and any problems are indicated on the new easy-to-read console (or by optional text message). The controllers also store full, downloadable run histories to assist with planned maintenance.

Each console, integrated within the front of the hood or in a separate control box if preferred, can communicate with up to 12 UV racks through unique numeric addresses on the system and can be linked to a Building Management System to assist with facilities management planning and reporting. The system is completely contained within the canopy and does not require a separate location for control panels or ballast boxes.

Reactocell can also be fully interfaced to building management and fire alarm systems, with optional text messaging of alarms so that maintenance engineers are alerted immediately a problem occurs.

The latest generation of Reactocell has also been configured to allow higher treatment capacity in a more compact design. This upgrade is combined with more energy-efficient electronic ballasts and a lamp life of 13,000 hours. Further efficiencies are achieved through the use of LEDs for task lighting.

Cost of ownership is further reduced through a range of design features, including easy access for maintenance and an internal pressure transducer for maintenance engineers to quickly prove air flow.

Reactocell works in conjunction with Halton’s KSA multi-cyclone filters to provide comprehensive treatment of exhaust air. The KSA filters are highly effective at dealing with medium to large grease particles, while the Reactocell oxidises small grease particles and grease vapours.

Reactocell technology uses UV-C light (185µm wavelength) and works in two ways. Photolysis breaks down the grease particles while, in parallel, ozone is generated to oxidise the remaining volatile organic compounds.
