Our business is simple. We make ultra precision
air temperature control systems to eliminate errors
in precision engineering.

Designed for enclosures with a footprint up to 3 m², the ATCU-2 is sized for diamond turning machines and metrology systems. 

When attached to diamond turning enclosures, the ATCU-2 includes a porous-fabric air distribution system that delivers laminar airflow over the lathe.
