Project Overview

Extechnology delivered a compact, high-performance odour control solution for Fuller’s — The Blue Boat, combining UV-C/ozone treatment with activated carbon filtration. The system was carefully integrated with upstream grease control to minimise plantroom footprint while delivering effective odour mitigation suitable for a sensitive location.

The design prioritised performance, maintainability, and predictable system resistance to ensure long-term operational reliability.

The Challenge

The site is located in a sensitive environment with nearby residential properties and outdoor seating areas in close proximity to the kitchen discharge point. Odour control expectations were therefore particularly stringent, with a requirement to minimise nuisance at all times of operation.

Key challenges included:

• Preventing odour impact on neighbouring residents and patrons

• Accommodating odour control equipment within a compact plantroom

• Maintaining manageable pressure drop across the system

• Ensuring filtration stages remained accessible for routine maintenance

The Solution

Extechnology engineered a multi-stage odour control system beginning with primary grease control at the canopy, followed by an electrostatic precipitator (ESP) stage to remove grease aerosols and smoke upstream of odour treatment.

UV-C/ozone treatment was introduced either in-duct or off-duct, depending on available space and duct configuration, and sized specifically to suit the kitchen airflow and cooking duty. This approach allowed effective breakdown of odorous compounds without unnecessary increases in system resistance.

A final activated carbon stage using Site Safe carbon modules was installed downstream to quench residual ozone and provide odour polishing, ensuring a clean and compliant discharge to atmosphere.

Technology Used

• RY5000B Electrostatic Precipitator (ESP) for upstream grease and smoke removal

• ECOVENT or iDUCT UV-C systems, selected to suit duct routing and space constraints

• Site Safe activated carbon modules for final odour polishing and ozone quenching

Project Outcomes

• Marked reduction in odour complaints following commissioning

• Effective odour control achieved within a compact plantroom footprint

• Maintainable system configuration with accessible UV-C lamp arrays and carbon cassettes

• No additional pressure penalties where off-duct UV-C treatment was selected

Consultant Notes

Activated carbon dwell time was engineered to approximately 0.2 seconds for odour treatment and 0.1 seconds for ozone quenching, ensuring effective performance without excessive system resistance. Differential pressure monitoring was incorporated to support condition-based carbon change-out and maintenance planning.
