Air Handling Unit Refurbishment 

Five Star Hotel. Knightsbridge, London.

The belt driven fans within the air handling units at a prestigious 5-star hotel in Central London had failed, resulting in no ventilation to several areas of the building which included the toilets and the kitchen. 

 

It was imperative that the ventilation was reinstated in these areas as a matter of urgency to ensure the Hotel was fully operational. 

 

The air handling units were installed on a mezzanine floor within a basement plant room. The access route to the AHUs was problematic with our engineers requiring the use of specialist lifting equipment to offload and position the new components up onto the mezzanine floor.

Fan Upgrade & AHU Remodelling

Prior to installation Halo HVAC validated all technical aspects of the system, designed structural modifications of the AHU, pre-wired all fans, along with Internal-rotor motor PM/EC technology that boasts an efficiency of IE6,  exceeding motor energy efficiency classes set by both the International Electrotechnical Commission and European Efficiency. 

 

The new maintenance-free fans were installed into the Air Handling Unit, for both supply and extract air streams. Along with bespoke manufactured reinforced bulk heads and fan openings for a seamless installation.

 

This combines three solutions in a way that previously seemed almost impossible: Reliability, outstanding system efficiency and 15–20-year extended life cycle for each AHU. 

 

 

High Efficiency Filtration System 

Although we have been known to utilise IAQ technologies such as UVGI, ionic and ozone treatment, to improve indoor air quality (IAQ). Considering the nature of this five-star hotels function, the likelihood of potential side-effects and down time is much lower with a suitably designed and maintained high-efficiency filtration system.

 

The system we developed and installed has ease and simplicity of maintenance at the forefront. We installed a new high-quality air filtration system designed to effectively capture and remove airborne contaminants. To ensure the hotels deep commitment to holistic wellness of all staff and guests, the new filtration system is compliant to ISO 16890-1:2016, EN 779:2012, DIN 53438-3 (F1) and OEKO-TEX® 100. 

 

With Halo HVAC IOT it is possible to continuously remote monitor IAQ and accurately adjust based on live data to guarantee a consistent maintenance schedule.

Lower Noise

When we begin the strategic design of a new fan system, our engineers design it so that the fan speed, and the vibration caused by the rotational speed, does not cause the system to operate in a region of resonance, we achieve this  through the calculation of the systems overall psychoacoustics.

 

With this project being a five-star hotel, peace and quiet is one certainty the guests want to experience. The result with our installation achieved a reduction of 11 dB(A) LpA. This was enabled thanks to upgrading the fans to a new system that uses no belts or pulleys with better air flow conditions, new reinforced fan bulk heads for less vibration, new anti-leak seals, new efficient heating & cooling coils and the use of noise reducing baffle and separation plates.

13 Air Handling Units serving a critical manufacturing process and science laboratories, all requiring refurbishments, controls and BMS modifications, delivered in 5 days, whilst achieving 26t a year CO2e reduction.

 

5 Star Hotel, Knightsbridge, London

The belt-driven fans in the hotel's air handling units failed, causing no ventilation in critical areas; urgent reinstatement was essential for to ensure the Hotel was fully operational & compliant.

 

Kettering General Hospital

Bringing the Air Handling Unit in line with compliances such as HTM 03-01 whilst reclaiming lost heat through new ventilation strategies, enabling energy savings.

 

Food Manufacturer, Rugby

Ventilation is vital for food production, ensuring air quality and contamination prevention. Upgraded filtration and AHU refurbishment guaranteed compliance, reliability and effectiveness.

 

Offices. Gracechurch Street, London 

With the building owners advertising for new leases a key objective was to ensure the indoor environment is comfortable and healthy. Over time, the existing AHUs became less efficient, leading to higher energy bills and reduced indoor air quality.

 

5 Star Hotel. Mayfair, London

This luxury hotel operates 24/7 therefore we had to deliver this project with zero disruption. We completed all works in 2 evenings whilst staging the works to allow for ventilation to continue during daytime hours.
