Bulk Gas Delivery Systems
SureFlow™ Bulk Specialty Gas Supply Systems and Controllers
Linde is revolutionizing flow rates for bulk ammonia as well as many other Specialty Gases. Our bulk gas systems significantly reduce the number of cylinder
change-outs required by conventional systems – helping customers achieve improvements in up-time, production costs, more consistent purity, and most importantly, safety.
The proprietary Linde enclosed heating system and new silicone
rubber heat blanket system allow for higher flow rates while maintaining controlled external ton container temperatures. These systems can be skid mounted to facilitate installation and movement around the facility. They deliver continuous ammonia
flows of 600 slpm with peaks greater than 3000 slpm.
Gases
- Ammonia (NH3)
- Chlorine (Cl2)
- Dichlorosilane (SiH2Cl2)
- Hydrogen Chloride (HCI)
- Halocarbon 14 (CF4)
- Halocarbon 23 (CHF3)
- Halocarbon 116 (C2F6)
- Halocarbon 218 (C3F8)
