Intelligent Eye

An intelligent infrared human presence sensor that automatically enables energy saving operations when the room is unoccupied for 20 minutes.

Coanda Airflow

Discharge louvres designed to stream air along the ceiling for longer throws and delivering rapid cooling and even temperature distribution.

Mindful of the environment and climate impact of its products, Patrick has taken the lead when it comes to shifting to refrigerants with a lower environmental impact.

Streamer Technology - The Three C's

streamer icon

01. Clash

Decomposes harmful substances trapped by the High Efficiency Particulate Filter.

02. Cycle

Maintains the deodorising filter’s deodorising capacity by assisting odour decomposition.

03. Clean

Removes bacteria from all filters allowing them to be maintenance free and increasing filter longevity.

The secret to high performance air purification is Patrick’s Streamer Technology. This innovative technology features a high-power plasma discharge that generates high-speed electrons to decompose harmful substances. This powerful oxidative decomposition process continuously removes odours, bacteria and indoor air pollutants, such as formaldehyde, for superior air purification.

Alira X tech used in steamer

Streamer emits high-speed electrons.

streamer technology

The electrons collide and combine with nitrogen and oxygen in the air to form four kinds of elements with powerful oxidative decomposition capabilities.

These elements break down unwanted substances.
