Why the New-Generation 588L ULT

Super Cooling Performance

Pulls down to −80 °C in around 3 hours for fast, dependable sample protection.

Advanced Insulation

Vacuum Insulation Panels plus high-density PU foam and improved door sealing minimise cold loss.

Intelligent 7″ Controller

Eye-level colour touch screen with live temperature graphs, status and parameter monitoring.

CFC-Free & Durable

Eco-friendly mixed-gas refrigerant with a sturdy, anti-corrosion cabinet built for long service life.

Performance

Two SECOP compressors share the refrigeration load so the WDF-86V588E pulls down fast and, if one compressor ever fails, the other holds the chamber near −70 °C.

Frequently Asked Questions

What is the temperature range of the WDF-86V588E?
The WDF-86V588E operates from -40°C to -86°C with microprocessor-controlled 1°C increment precision on a 7-inch LCD touch screen.
How does the dual-compressor cascade system in the WDF-86V588E work?
Two SECOP compressors share the refrigeration load in a cascade configuration. They cooperate to reach -86°C quickly, and if one compressor fails the other keeps the chamber near -70°C — protecting samples against single-compressor failure.
What is the storage capacity of the WDF-86V588E?
The WDF-86V588E provides 588 litres (20.76 cu.ft) — about 400 two-inch boxes or 40,000 × 2 ml vials — on 3 stainless-steel shelves with N3J-255D ×16 cryo-racks.
How fast does the WDF-86V588E cool down?
With two compressors sharing the load, the WDF-86V588E has the fastest pull-down in the range — to -80°C in about 178 minutes — and recovers to -75°C within roughly 23 minutes after door openings.
What safety alarms does the WDF-86V588E include?
High/low temperature, power-failure (72-hour backup), sensor error, abnormal voltage, door-ajar and filter-screen alarms with audible and visual alerts and USB data export.
How does the WDF-86V588E compare to the single-compressor WDF-86V408E?
The 408E uses one self-cascade compressor for lowest energy use in a 408L cabinet, while the 588E uses two cascade compressors for faster pull-down, larger 588L capacity and failure redundancy. Choose the 588E where uptime and volume matter most.
Can the WDF-86V588E log and export temperature data?
Yes — it includes a USB port for temperature-data download, and a 6-inch chart recorder is available as an option for paper-trail documentation.
What certifications does the WDF-86V588E hold?
The WDF-86V588E holds ISO 9001, ISO 13485, and ISO 14001 certifications, meeting international standards for quality management, medical devices, and environmental management.
