Breathing new life into your
Air Handling Unit.
As HVAC equipment ages and technology continues to advance, the costs associated with air handling units become proportionally greater and their reliability begins to reduce.
There are usually options to either refurbish or upgrade the existing plant items including air handling units which often have far reaching advantages over a replacement unit.
Refurbishment refers to the process of returning something to a good state of repair and upgrading is, essentially, the addition of new technology or features to older systems. Normally every project will require both elements to a greater or lesser degree.
Refurbishment can be anything from simply re-sealing condensate pans, chamber ﬂoors and other surfaces to replacement of controls, or a complete overhaul.
Replaced with the latest energy efﬁcient direct drive EC fans which are inverter controlled. New plug fans can use 15-20% less energy.
Poorly ﬁtting ﬁlters allowing bypass of unﬁltered air. Replacement frames can prevent this and potentially ﬁt higher-grade ﬁlters.
Replacement coils can be provided in sections which are then joined on site, replacing valves and actuators. Coils can also be ﬂat-packed.
Incorrect function of your AHU dampers is one of the biggest causes of poor AHU operation due to inaccurate air flow.
Rapid and demonstrable return on investment due to greatly improved energy efﬁciency, translating into energy cost savings of between 20-40%.
Improve reliability with minimal disruption and reduced downtime.
Contributes to sustainable development in the HVAC sector is through upgrading and refurbishment of heavy-use equipment like air handling units with significant carbon footprint savings.
Problems of installing different sized plant and logistics (e.g. crane lift) associated with transporting new plant to roof or plantroom are eliminated.
Reduces ongoing maintenance time and cost.
Helps AHUs adhere to energy efﬁciency standards deﬁned in the ErP (Energy-related Products) directive. The ErP Directive applies only to ventilation systems installed after January 1, 2016. This means heat recovery components (which increase AHU size by around 20%) are not required.
Upgrading fans may also lead to the potential to serve additional areas if duty upgrade allows.
