ScienTemp 85-3.1EX Explosion Proof Chest ULT Freezer – 3.1 Cu.Ft. –85°C

ScienTemp Corporation 85-3.1EX Explosion Proof Chest Freezer, 3.1 cu. ft., -45 C to -85 C, 59" Width, Class 1-Division 1 and 2 (Groups C and D), Polyurethane, 115 or 230 Voltage Options

The ScienTemp 85-3.1EX Ultra-Low Explosion Proof Chest Freezer is a highly specialized cooling solution engineered for the most demanding laboratory and industrial environments.

Designed to provide unwavering thermal stability, this unit maintains an impressive temperature range from -45°C down to –85°C, making it indispensable for the long-term preservation of volatile biological samples and sensitive chemical compounds. Despite its compact 3.1-cubic-foot footprint, it offers uncompromising safety by meeting strict Class 1, Division 1 and 2 (Groups C and D) requirements for hazardous locations.

The dual-stage refrigeration system, powered by a 1/2 HP compressor, utilizes specialized R-513A and R-508B refrigerants to achieve deep-freeze depths that standard industrial units simply cannot reach. Its robust polyurethane insulation and gravity-fed air circulation ensure that even at -85°C, internal conditions remain consistent and reliable.

Security is prioritized with a keyed hasp lock, while the analog dial controller provides a spark-free, fail-safe method for temperature management. Whether utilized in high-stakes pharmaceutical research or specialized petrochemical testing, the 85-3.1EX delivers the critical performance needed to protect both your high-value inventory and your facility's safety integrity.

Features

• ULT Hazardous Compliance: Fully certified for Class 1, Division 1 and 2 (Groups C and D), providing a spark-free environment for ultra-low temperature storage.

• Deep Cryogenic Reach: Engineered to sustain temperatures as low as -85°C (-121°F), ideal for genomic research, vaccine storage, and volatile chemical stability.

• Dual-Stage Refrigeration: Features a sophisticated high/low stage compressor system (1/2 HP) designed for rapid pull-down and long-term ultra-low reliability.

• Specialized Insulation: High-density polyurethane foam provides a superior thermal barrier to maintain deep-freeze integrity even in fluctuating ambient temperatures.

• Compact & Secure Design: The 3.1 cu. ft. capacity offers a space-saving solution without sacrificing industrial-grade security features like the keyed hasp lock.
