CRI SAMlink Control Systems

[ ]

SAMlink Control Systems are designed to control SAM units from a remote console or panel. Linked individually or in groups, an operator can increase or reduce airflow to a selected area and utilize the set back feature during off-peak hours, resulting in lower operating costs. Our exclusive state-of-the-art, reasonably priced fan filter control systems utilize our standard 115 volt and 277 volt, motor blower units without using high cost DC motors. Precise Airfl ow Control - SAM units are controlled individually or in groups, typically 1-4 units per address. - Fan speeds are set and/or adjusted from a console located outside the cleanroom without breaching the integrity of the cleanroom. Three levels of adjustment are possible: by Individual address / per Cleanroom zone / or Globally (all addresses) - The number of addresses is almost unlimited. - Room or equipment layouts with unique airflow requirements are easy to set and control.
