Featuring a 7-inch LCD touch screen, the unit offers intuitive control, real-time temperature visualization, and convenient USB data export, ensuring efficient monitoring and sample management. Its advanced cascade refrigeration system, powered by dual SECOP compressors, provides rapid pull-down performance, stable temperature uniformity, and long-lasting operational reliability.

Enhanced by VIP + PURF insulation and a multi-layer sealing structure, the MDF-86V728 minimizes heat loss, maintains consistent ultra-low temperatures, and optimizes energy efficiency even under challenging environmental conditions. Comprehensive safety protections—including high/low temperature alarms, power failure alerts, sensor error notifications, and 72-hour backup—ensure secure sample storage at all times.

Certified to ISO9001, ISO13485, and CE standards, this large-capacity ULT freezer is a trusted, high-performance solution for laboratories requiring dependable ultra-low temperature storage with advanced monitoring and operational safety.

Product Features

7” LCD Touch Screen Interface

Eye-level 7-inch color touch screen provides simple, intuitive operation with real-time temperature display, performance graphs, event logs, and freezer status monitoring. The built-in USB port allows convenient downloading of operating data for documentation and audits.
Super-Stable Cascade Cooling System
Utilizing the world’s most proven ultra-low temperature cascade refrigeration technology, this system delivers exceptional stability, long service life, and reliable performance. High-efficiency compressors ensure excellent cooling capacity even under extreme ambient conditions, while maintaining low noise (50 dB).
Rapid and Efficient Cooling Performance
The two-stage cascade cooling cycle, connected through a high-efficiency heat exchanger, enhances thermal exchange and ensures fast pull-down performance to -86°C. The system is optimized for energy efficiency and long-term sample preservation.
Advanced Thermal Insulation Structure
VIP insulation panels, thick high-density PU foam, and multi-compartment interior design minimize cold loss and significantly improve energy efficiency. The superior warm-up time provides extended sample protection in the event of power failure.
Multi-Layer Sealing & Anti-Frost Design

Multiple sealing layers, optimized door gaskets, and a heated door frame reduce cold air leakage and prevent frost buildup. This ensures stable internal temperatures, quieter operation, and improved compressor efficiency.
High-Level Safety & Monitoring System

Features a comprehensive alarm system (temperature, power failure, sensor error, door ajar), remote alarm interface, optional RS485/232 ports, and compatibility with LN₂/CO₂ backup systems. Optional 4G/WiFi data logger and temperature chart recorder further enhance traceability.
Flexible Expandability Options

Designed for diverse laboratory needs with optional water-cooling system, chart recorder, 4G/WiFi real-time monitoring, RS485 dry contact, and CO₂/LN₂ backup. Internal USB data logging is standard.
User-Focused Ergonomic Design

Includes automatic vacuum release for frequent door openings, ergonomic one-hand operation handle, file box for log storage, quick-release magnetic filter, built-in door lock with padlock slot, and heavy-duty universal casters for easy mobility.
Durable & Optimized Construction

Features a strong stainless steel interior with 27 mm PU-filled inner doors, reinforced shelves supporting up to 40 kg, detachable components for easy cleaning, and a robust exterior shell engineered for long-term service reliability.
Eco-Friendly and Energy-Efficient Operation

Constructed with CFC-free refrigerants (R290/R170) and environmentally friendly insulation materials. The system delivers quiet performance (50 dB) and energy-saving operation while maintaining stable cooling in harsh conditions.
International Certifications

Certified to ISO 9001, ISO 13485, and CE standards, ensuring reliable quality, safety compliance, and broad acceptance in global markets.
