Temperature-sensitive products—such as biopharmaceuticals, blood components, and vaccines—require precise, ultra-low temperatures to maintain their integrity and efficacy. Without the right freezing system, these valuable materials face risks like spoilage, reduced potency, or contamination. Over the last decade, advancements in cryogenics have reshaped how industries approach cold storage. A prime example is Cryometrix’s suite of liquid nitrogen (LN2) freezers and chillers, leveraging compressor-free technology to deliver faster cooling, lower operational costs, and improved product safety. Below is an in-depth exploration of how Cryometrix’s LN2 approach offers a competitive edge for businesses and laboratories aiming to preserve sensitive products at temperatures as low as -160 °C.
Liquid Nitrogen Technology vs. Conventional Mechanical Freezing
In a traditional mechanical freezer, compressors and chemical refrigerants (e.g., freon) are used to generate cold temperatures. While effective at achieving sub-zero conditions, these systems have significant drawbacks:
- High Energy Consumption: Compressors use considerable electricity and generate both noise and heat.
- Frequent Maintenance: Mechanical freezers involve many moving parts—motors, pumps, belts—which increases the likelihood of breakdowns.
- Environmental Impact: Certain chemical refrigerants can be damaging if leaked, and the accompanying heat load typically requires robust HVAC systems.
By contrast, liquid nitrogen (LN2) freezers rely on a contained LN2 reservoir that circulates cold throughout the freezer walls or internal channels—without subjecting operators or products to direct LN2 exposure. This design offers:
- Significantly Reduced Energy Usage: LN2-based freezers need minimal electricity, cutting energy consumption by up to 90%.
- Faster Temperature Pull-Down: Temperatures of -80 °C, -90 °C, or even -160 °C are reachable within minutes or hours, outperforming many compressor-based systems.
- Simplified Maintenance: Fewer moving parts mean fewer mechanical failures and less frequent servicing over the unit’s lifetime.
- Clean Emissions: Because LN2 is inert, it ultimately vents off as nitrogen gas, a harmless constituent of Earth’s atmosphere.
With these benefits, LN2 freezer technologies have gained significant traction in laboratories, blood banks, and manufacturing facilities that demand high levels of temperature control, reliability, and cost-efficiency.
Rapid Blast Freezers for Optimized Throughput
B-90 Blast/Thaw Freezer
Cryometrix’s B-90 Blast/Thaw Freezer exemplifies LN2-based engineering taken to new levels of speed and convenience. This upright unit pulls down from 20 °C to -90 °C in about 10 minutes, crucial for operations requiring quick “shock-freeze” capabilities. Whether used for plasma, biological samples, or other lab materials, the B-90’s performance can dramatically accelerate a facility’s processes. It also has thawing capabilities, allowing operators to set temperatures as high as +40 °C for in-unit thaw cycles.
Beyond speed, the B-90 offers a 20-year warranty on its cooling system, alleviating concerns about downtime in high-volume environments. On-board data logging ensures that every freeze-thaw cycle is recorded, while its upright stainless-steel interior provides easy access to stored materials.
MB-90 Miniature Blast Freezer
For faster freezing in a smaller footprint, the MB-90 Blast/Thaw Freezer occupies just 27 in × 56.5 in of space but delivers top-tier performance. It can reach -90 °C from ambient in as little as 3 minutes, making it indispensable for small test batches, pilot studies, or research labs exploring experimental freeze protocols. Despite its compact volume, the MB-90 still includes the same LN2-based efficiency, integrated data logging, and stainless-steel construction found in larger units.
This rapid freezing ability is particularly useful in scenarios where multiple freeze-thaw processes run concurrently, reducing the overall waiting period for each cycle. Researchers can operate near-instant freeze runs with minimal LN2 consumption.
Ultra-Low Temperature Storage for Biopharma and Research
T-90 Storage Freezer
For long-term storage at temperatures as low as -90 °C, Cryometrix’s T-90 Storage Freezer stands out for reliability and user convenience. While mechanical freezers may require hours to stabilize at -80 °C, the T-90 can reach similar temperatures in under 60 minutes. Its stainless-steel interior simplifies cleaning, thereby reducing cross-contamination risks in labs or clinical settings.
A core advantage of the T-90 lies in its cost-effectiveness. With LN2-based cooling, it draws minimal power and produces negligible heat exhaust, relieving facilities from heavy demands on air conditioning. Mechanical freezers often generate significant ambient heat, affecting room temperature and energy usage. LN2 systems largely sidestep that, maintaining a consistent lab environment.
T-160 Ultra-Low Temp Freezer
When even colder temperatures are required—for instance, -160 °C for advanced therapies, cell cultures, or certain vaccines—the T-160 Ultra-Low Temp Freezer provides a highly stable platform. Key features include:
- Battery Backup for 7 Days: Protects valuable materials from temperature excursions during power outages.
- Redundant LN2 Valves: Ensures continuous cooling even if one valve malfunctions.
- cGMP Compatibility: Offers 21 CFR Part 11 compliance and IQ/OQ/PQ documentation, catering to heavily regulated production environments.
By reaching -160 °C without subjecting materials to open LN2, the T-160 marries ultra-cold functionality with the convenience and safety of an upright access design.
Specialized Chillers for Ethanol Extraction and Winterization
LN2 has become integral to various industrial processes, notably CBD extraction and winterization. Super-chilled ethanol is used to filter out unwanted waxes or plant material, enhancing purity in the final product.
L-80 Lite Chiller
The L-80 Lite Chiller serves small- to mid-sized extraction facilities by cooling 30 gallons of ethanol to -40 °C in roughly 8 minutes (and potentially to -80 °C in under 20 minutes). Its modular design enables seamless upgrades as production scales. Full stainless-steel construction supports high cleanliness standards, beneficial in regulated industries like nutraceuticals or pharmaceuticals.
L-80 Max Chiller
For larger operations handling higher volumes, the L-80 Max chills up to 120 gallons of ethanol to -80 °C in under an hour. Eliminating compressors reduces downtime and simplifies maintenance, further enhancing throughput. By drawing less electricity, facilities can notably reduce their overall carbon footprint.
Temperature-Controlled Transport and Shipping
Transporting temperature-sensitive goods has long relied on dry ice, which can be labor-intensive, inconsistent, and hazardous. Cryometrix addresses these concerns with portable LN2-based units:
S-90 Low Temperature Shipper
The S-90 Shipper can maintain set points between +20 °C and -90 °C for up to 15 days, completely avoiding dry ice and its associated complexities. With a self-contained LN2 reservoir and battery-powered control systems, the S-90 can be loaded and deployed quickly. A pneumatic latch door, accessible only via user-specific credentials, preserves security during transit.
RMF-90 Freight Freezer
Intended for both ground and air travel, the RMF-90 provides a temperature range of -40 °C to +40 °C. Its versatility suits labs, biopharma manufacturers, or logistics companies that must ship critical items worldwide. During flight, it can maintain stable conditions without the large, ongoing additions of dry ice.
