Vent-Axia’sSentinel Apex efficiently ventilates Carmarthen Health and Wellbeing Hwb Project
Vent-Axia’s award-winning Sentinel Apex units have been specified for the landmark Carmarthen Health and Wellbeing Hwb project, delivering energy- efficient ventilation to this transformative multi-million-pound development.
T
he 245,000 sq ſt scheme is repurposing the former Carmarthen Debenhams building into a Health and Wellbeing Hub. The new hub will offer a range of services including public healthcare, a Customer Service Hwb, a new 24-hour Actif gym and a family entertainment centre.
The development will benefit from Sentinel Apex units installed across all three floors of the building, with four Sentinel Apex HR21 specified to meet the demand of the gym area alone. The extensive refurbishment involved a full reconfiguration of the internal space to create a welcoming environment that balances health, wellbeing, and entertainment under one roof. The Sentinel Apex commercial heat recovery units were specified for their energy efficiency, good indoor air quality, and their ultra-quiet operation, as well as meeting stringent Specific Fan Power (SFP) and dBA acoustic requirements, ensuring a comfortable and compliant building. Neil Higgins, contracts manager, F P Hurley & Sons said: “We chose the Sentinel Apex units because they deliver exceptionally quiet operation and low Specific Fan Power, ensuring they met all Building Regulation requirements. The units were also available in a wide range of airflows, allowing us to specify the correct units for each space. In short, they offered the ideal balance of airflow, low noise, and energy efficiency.”
Adam Bullon from Ventilation Warehouse added: “I have worked with Vent-Axia for a long time. The Carmarthen Health and Wellbeing Hwb was an interesting job with the Sentinel Apex ticking all the right boxes for the project, including energy efficiency, noise, and ease of maintenance. Twenty Sentinel Apex units were delivered over three project stages.” A brilliant fit for the Carmarthen Health and Wellbeing Hwb project, the Vent-Axia Sentinel Apex is the next generation of commercial heat recovery ventilation, providing specifiers help in creating low-carbon buildings. The Sentinel Apex is specifically designed to have a high level of energy efficiency with industry-leading SFP and low embodied carbon.
The Sentinel Apex offers the highest level of IAQ and thermal comfort, whilst maintaining the lowest energy and noise levels, both of which were vital for this refurbishment. Offering up to 93% heat recovery efficiency (EN308 test method), ultra-low sound levels and extremely low SFP, the Sentinel Apex also has intuitive controls compatible with Vent-Axia’s range of Sentinel-X Sensors, allowing for easily configurable set points ensuring optimised IAQ. In order to achieve the highest levels of IAQ, the Sentinel Apex unit features ePM10 50% extract and ePM1 55% supply filters (M5/F7 equivalent) as standard. By carefully selecting the filter media and by utilising the latest motors and impellers (with better than IE5 efficiency), the Sentinel Apex maintains an extremely low SFP with low sound levels whilst maintaining excellent IAQ.
Specifiers can choose from five sizes, as the Apex has been developed for a wide range of applications, and delivers airflows up to 4000m3/ hr. At the Carmarthen Health and Wellbeing Hwb 20 Sentinel Apex units were installed, including four Sentinel Apex HR21s used in the ground floor gym area alone, while Sentinel Apex HR15 units were used for the offices on floor 1 and floor 2, ensuring air flow meets design requirements in different parts of the building. Well-suited to the Carmarthen Health and
Wellbeing Hwb, the Sentinel Apex system, with the matched range of Sentinel-X Sensors, can monitor occupancy and air quality, responding by adjusting the ventilation accordingly, to maintain the IAQ and thermal comfort within predefined limits, whilst recovering up to 93% of the extracted thermal energy.
The Sentinel Apex’s new advanced integrated control system has three levels of interface, all as standard: simple purpose-designed onboard user interface controlled incorporating an alphanumerical, 2-line display which lets users know how the system is operating with 4-button keypad for fan status and a basic commissioning setup mounted within the control panel. The controls are designed to take the complexity out of the control system making it easy for the user, with two levels of interface: one for the engineer allowing commissioning and one simpler one for the end-user allowing them to easily monitor and boost the system if additional ventilation is required. Designed to have a low embodied carbon footprint, Vent-Axia has used the CIBSE TM65 data collection methodology to collect accurate, detailed embodied carbon information for the Sentinel Apex, working from a component level up.
