SAMlink Control Systems Designing Flexible Solutions Flexible, Energy Efficient, User Friendly Systems General Information 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. SAMlink System 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 Airflow 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. Lower Installation Cost • Installation is seamless and quick. Fewer breaker lines reduce material and electrical contractor costs. • Reductions in on-site power distribution wiring lower contractor labor cost. • Installation cost is lower as a result of simplified balancing and adjusting capabilities along with reducing the time required at start-up. • Reduced certification costs. Lower Maintenance Costs • Recalibration and balancing of rooms is simplified. • Small zone shut-down enables isolated upgrade or maintenance operations to take place without disrupting or affecting the integrity of the cleanroom.

A typical SAMlink Control System consists of an address or groups of addresses with four or more SAM units per address as shown in Fig. 1. Each address is controlled by a panel or wall mounted console as shown in Fig. 2. Each address includes the following components: • Group of four (4) SAM 24 Fan Filter Units consisting of (1) Master Unit and (3) Slave Units. • Choice of 115 or 277 volt AC impeller type motor blower assembly. • Control Console, panel or wall mounted. • With L.E.D. readout and user friendly control features. • Wiring for each group of four (4) SAM units. • HEPA or ULPA Filters with 53 mm media pack. Soft Start Capability SAMlink Systems with adjustable soft start holds start-up to under 0.8 amperes per 277 Volt SAM unit. This results in major cost savings during installation, reducing electrical breaker requirements by as much as 50%. SAMlink Options • HEPA or ULPA Filters with 70mm deep pleated design for increased operating efficiency. • Choose either NCR or CRF Style SAM units. • Single or multiple SAM units per control address with four per address is most common and economical. 406 Fig. 2: Touchscreen Console Shown (other consoles available)
