If pressure, humidity and/or temperature control or frequent cleaning and sterilization are required, Terra recommends selecting a hardwall modular cleanroom. For any questions regarding your application, please speak with a Terra representative.
This chart suggests FFU quantities to meet ISO requirements for common cleanroom sizes; call for more information, or use Terra’s QuickQuote form to convey your custom ISO 5/Class 100. A complete system includes one or more Power Distribution Modules, which provide power to ceiling lights and Fan/Filter Units.
For applications requiring UL-listed products, you must request a declaration of system listing under UL File E472687 at the time of order, which covers all high-voltage Modular Cleanroom electrical components integrated into Power Distribution System. UL listing helps meet municipal and other permitting requirements that may apply, while ensuring the safety and integrity of electrical components.
Terra cleanrooms are designed to meet a specified ISO cleanliness rating while in use: with operations in progress, process machinery humming, and personnel in motion. So why maintain that level of performance when a production shift ends and personnel leave for the day?
A cleanroom at rest maintains its target ISO cleanliness standard with much less airflow, fewer air changes—and decreased power consumption. Terra’s Night Service Switch activates a separate operation circuit that drops all Fan/Filter Units (FFUs) into low-energy operation mode, shaving 25% of energy costs from your power bill while maintaining uninterrupted cleanroom performance at your specified cleanliness level (see chart below). With Terra's Night Service Switch, operators can save up to 7,000 kilowatt-hours per year based on a cleanroom system utilizing 10 FFUs.
Operation Setting | Airflow: cfm (m^3/hr) | Air Speed: ft/m (m/s) | Run Amps (Watts) |
---|---|---|---|
High Speed | 808 (1373) | 115 (.58) | 4.3 (512) |
Medium Speed | 717 (1218) | 102 (0.51) | 3.5 (416) |
Night Service | 654 CFM (1111) | 93 ft/min (0.47) | 3.3A (393W) |
