Are Your AHUs Ready For The Early Pollen Season?
The record-breaking warm spell at the end of February has brought about an earlier than usual start to the pollen season – bad news for both hay fever sufferers and HVAC plant.
Tree pollen in particular has started causing an issue ahead of schedule, blocking noses and air intakes alike.
To prevent blockages of a mechanical nature, ECEX Air Intake Screens provide a simple and cost-effective solution. Fitted externally to the air intake, the long-lasting mesh filter traps pollen and other airborne debris – such as leaves, dust and litter – preventing these unwanted objects from entering the system and compromising the efficiency of the HVAC plant; ideal for Air Handling Units (AHUs), chillers, dry air coolers, cooling towers and air conditioning.
By stopping this debris savings can be made across the board, including improved efficiency, extended life of internal filters, plus a reduced maintenance requirement as the internal workings avoid clogging and fouling. Importantly, ECEX Air Intake Screens have minimal impact on airflow and static pressure.
Ensuring AHUs withstand the most challenging seasons doesn’t just end with ECEX Air Intake Screens. Essential maintenance and in some cases, refurbishment is also key to ensuring efficiency and avoiding breakdown.
AHU refurbishment can entail anything from simply re-sealing condensate pans, chamber floors and other surfaces to the wholesale replacement of controls, or even a complete overhaul. By upgrading crucial parts, such as fans, considerable energy savings can be achieved. On a recent project, we calculated that fan upgrades lead to a 22% – 33% energy saving.
Refurbished AHUs when combined with ECEX Air Intake Screens make for a cost-effective solution, that will keep older plant operational for longer and able to withstand the changing season.
ECEX Air Intake Screens prevent airborne debris such as pollen, leaves, insects and litter from clogging internal coil fins, perishable filters and other components. For more information, click here.
