Office Rack Acoustic 12U Now Equipped with New PWM Fan System and Enhanced Temperature Controller
by Marketing
Lehmann IT has updated its Office Rack Acoustic 12U (600×800×660) with a new generation of temperature‑controlled PWM fans and an improved controller unit designed for quieter and more efficient cooling. The upgraded model is engineered for noise‑sensitive IT environments such as offices, studios and meeting rooms, where active hardware must operate reliably without disturbing the workspace.
The new cooling system includes three PWM fans — two exhaust fans at the top and one intake fan at the bottom. All fans automatically adjust their speed based on the internal temperature, ensuring optimal airflow with minimal noise. The redesigned controller features a clear LED temperature display, more precise regulation and support for up to four PWM fans, allowing future expansion if required.
The Office Rack Acoustic 12U maintains its proven sound‑insulated construction, reducing equipment noise by up to 38 dB. Adjustable 19‑inch mounting rails, multiple cable entry points, lockable access doors and a maximum installation depth of 550 mm provide flexibility for switches, firewalls, compact servers and other active components.
With its combination of improved PWM cooling, precise temperature control and effective acoustic insulation, the updated Office Rack Acoustic 12U offers a reliable solution for IT installations that must remain quiet, secure and thermally stable in everyday office environments.
