SMARTEMP products are developed in the R&D laboratory in Marrickville, Sydney, in collaboration with manufacturing engineers at the SMARTEMP factory in China. Design models are created using 3D CAD, with in-house rapid prototyping for product fine-tuning and testing in the SMARTAIR DIFFUSION laboratory. 



SMARTEMP products are manufactured in the SMARTEMP factory, with local assembly and warehousing of key products in Australia and New Zealand for the Australasian market, and in Germany for sales within the EU. 




The SMARTEMP range of high induction air diffusion swirl technology includes ceiling swirl diffusers for low temperature VAV applications, as well as a variety of specialised ceiling and side-blow swirl diffusers for large volume spaces.  The latter includes the world's highest capacity adjustable pattern swirl diffusers. The patented design offers variable air pattern adjustment from horizontal to vertical, providing cost effective, energy efficient and quiet solutions for high comfort, draught-free applications, such as convention centres, sports arenas, performing arts spaces, TV studios, distribution centres, and similar.  Many of the swirl diffusers offer an option of manual, electric or self-powered thermal actuator discharge direction adjustment. 



SMARTEMP's range of floor swirl diffusers includes the world's only floor swirl diffuser with user-adjustable airflow rate, direction and pattern.  The low profile distribution basket includes the option of motorised VAV operation. The patented design maximises thermal comfort personalisation via user-adjustment of both local airflow rate and local air motion.  "Warm head / cold feet" discomfort at low airflow rates is avoided by maintaining throw to head height of seated occupants regardless of the diffuser airflow rate setting (manual or VAV). 



SMARTEMP offers a range of perforated displacement diffusers, both for commercial and auditorium applications. These, like their floor swirl diffuser counterparts, realise high comfort levels and enhanced indoor air quality to achieve elevated levels of occupant wellbeing. Perforated displacement diffusers include rectangular displacement, drum displacement, wall displacement, step displacement and floor displacement diffusers.
