A-Texas began research and development on this range of product after the launch of our Manhattan series of elevator airconditioners in 2003. As most lift lobbies are non-airconditioned, ingress of external warm moist air into the airconditioned lift usually causes condensation on the grill / diffuser surfaces.
Extensive R&D and beta-site testing since year 2003 has resulted in 4 grill / diffuser types, a wide range of air distribution configurations and ancillary accessories to provide solutions to surface condensation problems. A very in-depth understanding of airflow patterns (flow paths, flow balance, reflux, etc) in different types of grills / diffusers and the ambient air characteristic flux (RH, dew-point, air mass contraction) has been applied to our R&D to result in products that function to expectations.
We are aware of ‘solutions’ peddled in the market using grill surface treatment and coatings; these, from clients’ feedbacks, have not performed satisfactorily in condensation prevention; with some cases, algae formation happens after one year on the wet grill surfaces. The treated surfaces wholly lack aesthetics.
Also, there are others that make plastic or wooden grills, they are also aesthetically compromised and colour matching will be a problem. Plastic grills have a possibility of warping as temperature gradient exists throughout the linear grills. Wooden grills are bulky and clumsy. Most plastic and wooden grills, if not all, have problem meeting Class “0” fire rating requirements by authorities. Our grilles are class “0” fire rated, it conforms to Fire Safety Bureau regulation for installation at both public and commercial premises.
Our Dry-Flow range does not use surface treatment or material change. It is about application of technology and re-designing the air distribution devices.
