ULTRAL LN₂ & LAr: Cryogenic Liquid Purifiers
Cost-effective automatic purifiers for bulk liquid nitrogen (LN2) and liquid argon (LAr). Designed to strip impurities down to the sub-ppb level directly from delivery trucks to secure your semiconductor manufacturing supply.
In microelectronics and optoelectronics, ultra-pure liquid nitrogen and liquid argon are critical utilities. However, standard industrial deliveries from tanker trucks often contain trace impurities that can severely disrupt sensitive manufacturing processes. The ULTRAL LN2 and ULTRAL LAr provide a direct, highly effective solution. Positioned upstream of your site's storage tanks, they purify the cryogenic liquids straight off the delivery truck during container stripping, acting as a crucial high-purity safeguard and an excellent backup for on-site gas generators.
Upgrading bulk commercial liquid nitrogen or argon on-site provides semiconductor fabs with immense logistical and financial advantages over purchasing premium pre-purified specialty gases.
Large flow capacity: Engineered specifically for bulk offloading, safely handling large liquid flow rates of up to 16,000 L/h at working pressures up to 17.5 barg.
Sub-ppb guaranteed purity: Employs advanced cryo-trapping and chemisorption to reduce incoming impurities (up to ppm level of O2, CO, and CH4 depending on the gas) down to strictly < 1 ppb. Optional hydrogen (H2) removal is also available.
Built-in particle filtration: Features an integrated < 3 µm particle filtration system at the output, ensuring no physical contaminants reach your ultra-pure storage tanks.
Cost-effective OPEX: Lowers the cost of bulk gas procurement by allowing you to buy standard industrial-grade LN2 or LAr and purify it locally.
Simple, single-operator integration
Offloading liquid gases from a tanker truck must be fast, safe, and efficient. Both the ULTRAL LN2 and LAr models are specifically designed as easy-to-use automatic purifiers.
Despite their massive 16,000 L/h flow capacities, the skids are highly compact (measuring just 2,000 x 1,400 x 3,000 mm). This allows for seamless integration directly at your facility's loading bay or immediately upstream of your main liquid storage infrastructure.
Rapid adsorbent regeneration
The ULTRAL series purifies the liquid utilizing a high-performance adsorbent bed based on cryo-trapping and chemisorption principles.
Because they handle bulk offloading, the system’s autonomy depends on the incoming level of impurity. However, once the adsorbent bed reaches its capacity, the system does not require lengthy offline maintenance. The bed can be completely regenerated and reconditioned at low temperature in less than 24 hours. This rapid turnaround ensures the purifier is always ready for the next scheduled bulk tanker delivery.
Frequently Asked Questions (FAQ)
What is the primary use case for these purifiers?
They are used to purify bulk liquid nitrogen or liquid argon straight from a delivery tanker truck directly into a facility's storage tank. They are highly recommended as a high-purity backup system for fabs that utilize on-site gas generators.
What specific impurities do they remove?
The chemisorption technology eliminates oxygen (O2), carbon monoxide (CO), and methane (CH4) from inlet at ppm levels down to < 1 ppb. Hydrogen (H2) removal (from 50 ppb to < 1 ppb) is also available as an optional feature.
Can this handle the speed of a standard truck delivery?
Yes. The systems are engineered to handle liquid flow rates up to 16,000 Liters per hour, ensuring that tanker truck offloading is never bottlenecked by the purification process.
