Turtle Bay — Northern Quarter

Project Overview

Extechnology delivered a standardised, high-performance odour control stack for Turtle Bay’s Northern Quarter restaurant, designed to provide predictable filtration outcomes and streamlined servicing. The system combines electrostatic precipitator filtration, UV-C/ozone treatment, and activated carbon polishing, creating a repeatable specification suitable for deployment across a wider restaurant estate.

The approach focused on consistency, maintainability, and reliable performance in a challenging urban environment.

The Challenge

The Northern Quarter location operates a high-intensity cooking profile within a dense urban setting, with residential properties in close proximity to the kitchen discharge point. Low-level discharge constraints increased the risk of odour impact, requiring robust odour control without excessive system resistance.

Key challenges included:

• Managing high grease and smoke loads from intensive cooking

• Preventing odour nuisance in a residential environment

• Designing within restricted discharge heights and urban constraints

• Ensuring predictable performance and ease of maintenance

The Solution

Extechnology engineered a standardised multi-stage filtration and odour control system, beginning with an electrostatic precipitator (ESP) stage to remove grease aerosols and smoke particulates upstream of odour treatment.

UV-C/ozone treatment was introduced using iDUCT system, selected to suit duct geometry and available space, and sized specifically to match kitchen duty and airflow. This stage effectively breaks down odorous compounds within the airstream.

A final activated carbon polishing stage using Site Safe carbon modules was installed downstream to quench residual ozone and ensure odour targets were achieved prior to discharge.

Technology Used

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

• Ozone System ECOVENT iDUCT UV-C systems.

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

Project Outcomes

• Consistent odour reduction and a measurable decrease in complaints

• Predictable system performance across a demanding cooking profile

• Repeatable specification enabling faster and more efficient estate roll-outs

• Planned maintenance regime incorporating washable filtration stages and scheduled carbon change-outs

Consultant Notes

Fan selection was undertaken with full allowance for total system resistance across all filtration stages. Differential pressure monitoring points were installed across the carbon stage to support data-driven media replacement and long-term performance management.
