PEAK Titan LN240 On-Site Liquid Nitrogen Generator

Overview

The PEAK Titan LN240 is an on-site, skid-mounted liquid nitrogen (LN₂) generator engineered for continuous, high-reliability production of ultra-high-purity cryogenic nitrogen in laboratory and clinical environments. Utilizing pressure-swing adsorption (PSA) technology followed by cryogenic liquefaction, the system separates ambient air into high-purity nitrogen gas (>99.999% N₂), then cools and condenses it into liquid nitrogen at −196 °C. Unlike conventional bulk delivery models, the Titan LN240 eliminates dependency on third-party logistics, transport hazards, evaporation losses during transfer, and scheduling constraints—delivering operational autonomy while maintaining strict compliance with ISO 8573-1:2010 Class 1 compressed air quality standards for nitrogen feed gas and ISO 8573-7:2003 for liquid phase purity. Its integrated 500 L vacuum-insulated storage dewar enables stable, on-demand supply for critical low-temperature applications without intermediate handling.

Key Features

• Skid-mounted modular architecture with factory-integrated PSA nitrogen generation, liquefaction cascade, and vacuum-jacketed storage—designed for rapid installation and minimal site preparation
• NPFS™ (Nitrogen Pulse Flow System): Patented pulsed-flow liquefaction control that optimizes thermal efficiency and reduces compressor cycling, extending component lifetime and improving long-term reproducibility
• “Boost” pressure augmentation mode: Dynamically increases system discharge pressure up to 12 bar(g) without additional energy input—enabling direct filling of high-pressure cryogenic transfer lines or automated sample storage systems
• Intelligent level management: Dual-mode ultrasonic + capacitive liquid level sensing with automatic standby activation upon reaching full 500 L capacity; real-time dewar vacuum integrity monitoring via integrated vacuum gauge
• Onboard oxygen analyzer (0–25% O₂ range, ±0.1% accuracy) and integrated water-cooled heat rejection system ensure stable operation under ambient temperatures up to 35 °C
• 7-inch industrial-grade color touchscreen HMI with multilingual UI, event logging, alarm history, and configurable setpoints for flow rate, pressure, and fill duration

Sample Compatibility & Compliance

The Titan LN240 is certified for use in GxP-regulated environments including GLP-compliant research laboratories, ISO 13485-certified medical device manufacturing, and FDA-regulated IVF clinics. It meets IEC 61000-6-2/6-4 for electromagnetic compatibility and carries CE marking per Machinery Directive 2006/42/EC and Pressure Equipment Directive 2014/68/EU. All wetted surfaces contacting liquid nitrogen are electropolished 316L stainless steel, passivated per ASTM A967, and validated for extractables/leachables per USP . The system supports 21 CFR Part 11-compliant electronic audit trails when connected to PEAK’s optional LabLink™ software suite.

Software & Data Management

PEAK LabLink™ (v3.2+) provides centralized remote monitoring, predictive maintenance alerts, and secure data export (CSV/Excel). Each unit logs timestamped records of nitrogen purity (O₂ residual), dewar level, vacuum pressure, cooling water temperature, and compressor runtime—retained for ≥12 months onboard and exportable for regulatory review. Role-based user access control, encrypted communication (TLS 1.2), and configurable alarm thresholds support alignment with ISO/IEC 17025:2017 Clause 7.7 (data integrity) and EU Annex 11 requirements.

Applications

• Cryopreservation of oocytes, embryos, and stem cell lines in IVF and regenerative medicine labs
• Long-term biobanking of genomic material, primary tissues, and microbial strains
• Cryogenic grinding and milling in pharmaceutical QC and materials science
• Low-temperature electron microscopy specimen preparation and storage
• Controlled-atmosphere packaging validation in food safety and veterinary diagnostics
• On-site cooling for superconducting MRI magnet quench recovery and semiconductor wafer testing

FAQ

Does the Titan LN240 require external liquid nitrogen for startup?
No—the system performs full cold-start from ambient air using integrated precooling stages and auto-purging protocols.
What is the typical nitrogen purity delivered to the dewar?
≥99.999% N₂ with ≤1 ppmv O₂, ≤0.5 ppmv H₂O, and ≤0.1 ppmv hydrocarbons—verified per ISO 8573-7 Annex B.
Can the unit be integrated with existing cryogenic infrastructure?
Yes—standardized 3/4″ VCR fittings, Modbus TCP interface, and optional 4–20 mA analog outputs enable seamless integration with LIS, BMS, or automated freezer networks.
Is routine calibration required for the onboard oxygen analyzer?
Factory-calibrated with annual verification recommended; traceable to NIST-standard gas mixtures.
What maintenance intervals apply to the PSA columns and liquefaction compressors?
PSA adsorbent life: ≥60,000 hours; oil-free scroll compressors: 20,000-hour service interval with scheduled filter replacement every 2,000 hours.
