April 10, 2026 — ChiEnCheng officially launches the new -120°C deep cryogenic freezer (Model: CEC-DL120). Following the successful -86°C ULT freezer and -150°C cryogenic storage freezer, this product represents another milestone in ChiEnCheng's deep cryogenic refrigeration capabilities. The CEC-DL120 utilizes a self-developed cascade compression refrigeration system to maintain stable operation at -120°C, providing reliable deep cryogenic storage for CAR-T cell therapy, stem cell storage, and gene therapy applications.
Breaking -120°C: Filling the Domestic Gap
The rapid development of CAR-T cell therapy, stem cell storage, and other cutting-edge medical technologies has set more stringent requirements for biological sample storage temperatures. Research shows that at temperatures above -80°C, cell membrane integrity and DNA stability gradually decline over time, while storage below -120°C through vitrification can effectively suppress these degradation reactions, extending sample viability for decades.
The ChiEnCheng CEC-DL120 can achieve cabinet temperatures as low as -125°C (limit: -130°C), with temperature uniformity of ±3°C, meeting the stringent requirements for deep cryogenic storage in cell therapy and reproductive medicine. This product fills the gap in the domestic market for mature commercial equipment in the -120°C temperature zone.
Core Technology: Cascade Compression Refrigeration
The CEC-DL120 employs a dual-stage cascade compression refrigeration architecture, using eco-friendly mixed refrigerants (R290+R170) to achieve ultra-low evaporation temperatures while maintaining energy efficiency and reliability. The unit features a 7-inch industrial touchscreen control system with real-time temperature curve display, data logging and export (USB/Ethernet), and remote alarms (SMS/email/WeChat) for round-the-clock sample protection.
The chamber uses high-purity aluminum alloy materials combined with vacuum insulation panel (VIP) technology, significantly reducing cold loss and achieving approximately 25% lower energy consumption compared to similar products. Additionally, the CEC-DL120 offers an optional liquid nitrogen backup system (LN2 backup) that can maintain temperatures above -100°C for up to 72 hours during extreme power outages.
Market Positioning & Applications
The CEC-DL120 is primarily targeted at: biopharmaceutical companies (CAR-T cell production lines, viral vector storage), large hospitals (cell therapy centers, reproductive medicine centers), research institutions (stem cell banks, organoid banks), and contract development and manufacturing organizations (CDMOs). ChiEnCheng also provides customization services to adjust chamber dimensions, storage capacity, and control system configurations based on customer requirements.
The new product is now available for global orders, with first deliveries scheduled for June 2026. For more product details and quotes, please call +86 189 1072 7740 or email info@chienchengfreezer.com.
