The Dilution Air Processing Unit (DAPU) is an ideal solution for small and medium businesses to prepare themselves for the Covid-19 new normal by employing an enhanced air ventilation technique. The DAPU system allows the creation of zones (e.g. sickbays, waiting rooms, etc.) within workplaces with no recirculation of air. This prevents cross-contamination of unclean air in between the zones. This solution is suitable for hotels and other premises to be used for quarantine purposes.
The DAPU consists of the following key features:
The DAPU can also be deployed in any area without an existing air-conditioning system making it highly versatile.

Key Performance advantages:
DAPU is an innovative solution for enhanced ventilation and reduced transmission of airborne infectious diseases. Its aim is to offer an easily implementable and low-cost solution for 100% fresh air supply to buildings in curbing infections during a pandemic. The system has 25% less energy consumption in comparison to conventional options and maintains the optimum humidity range at 45% to 55%. The modular design feature makes it unique and can be easily retrofitted to buildings. DAPU achieves 60% reduction of integrated airborne particle concentration in comparison to ordinary air-conditioners (with 100% recirculation).
DAPU could be an ideal solution when it comes to the creation of isolation zones within buildings to curb the spread of infectious diseases. This can play a vital role in safeguarding public health and ensuring global health security.
Examples of practical applications are as follows:
The DAPU technology demonstrates the innovative strategy in improving the capabilities of existing solutions and applying novel concepts to a very challenging situation such as pandemic control. The estimated market size for this technology could be largely due to its sustainable approach in meeting the demands for an expanding healthcare facility in the future.
For pandemic control, DAPU can be operated indoor for the test chamber with 1 patient and 1 attending nurse/staff. This setup has a simple payback of less than 2 years. However, for high usage areas such as swab test stations in airports or conference venues, simple payback is expected to be less than a year.
The business case for DAPU can only be properly articulated after this solution has been deployed in an actual situation and feedback obtained from stakeholders. This will ensure the integrity of the information provided and improvements to be made to ensure wider adoption of the system by other companies.
