Binder Ultra-low temperature freezers (ULT)
Operational integrity is maintained by a state-of-the-art multi-level safety concept that secures the long-term viability of stored materials. This concept includes a robust design ensuring samples remain below critical temperature thresholds for over 30 hours during power interruptions, complemented by an electromechanical door lock and PIN-code access control to prevent unauthorized temperature fluctuations and entry.
The system prioritizes sustainable and economical performance through an environmentally-friendly design, featuring a highly efficient cascade compressor cooling system and the exclusive use of climate-neutral refrigerants. This engineering focus results in permanently low electricity costs over the unit’s service life while guaranteeing a constant, ultra-low temperature, ensuring resource optimization without compromising sample stability or preservation efficacy.
The thermal management system utilizes a precision cascade compressor cooling unit to achieve and maintain constant temperatures within the -40°C to -90°C range, with fine control adjustable to an accuracy of one degree. This stringent temperature regulation is critical to prevent degradation and loss of efficacy in highly sensitive materials like vaccines and complex biological specimens.
Security against unauthorized physical and operational access is addressed through an integrated electromechanical door locking system coupled with PIN code access control. Furthermore, the electronic controller features password-protected adjustment menus, ensuring that critical temperature setpoints and operational parameters cannot be inadvertently or maliciously altered, thereby maintaining process reliability.
The use of advanced Vacuum Insulation Panel (VIP) technology significantly enhances thermal retention capabilities. This high-performance insulation minimizes heat ingress, which is pivotal for maintaining stable ultra-low temperatures and contributing directly to the unit's best-in-class energy efficiency and extending the duration of sample protection during power failure events.
Integrated fault analysis systems provide immediate feedback on operational deviations. The controller automatically detects temperature changes outside the specified tolerance, activating simultaneous visual and acoustic warnings and alarms, allowing technical personnel to initiate corrective action rapidly and minimize exposure risk for valuable materials.
The interior construction features a long-lasting, rust-proof sample chamber and an insulated inner door coated with stainless steel, ensuring material compatibility and simplifying decontamination procedures. The smooth internal surfaces facilitate effortless cleaning, preventing cross-contamination and adhering to stringent laboratory hygiene and workflow protocols.
Designed for maximum longevity and minimal environmental impact, the refrigeration cycle operates exclusively with climate-neutral and CFC-free safety refrigerants. This conscious engineering choice supports global sustainability mandates while ensuring powerful, reliable cooling capacity necessary for consistent ultra-low-temperature storage over decades of service.
Beyond core function, the equipment is designed for efficient workflows, incorporating practical unit sizes and a reduced footprint to optimize valuable laboratory space. The combination of excellent usability and maximum process reliability is intended to make daily operations efficient and accurate, particularly in high-volume or constrained laboratory environments.
The multi-level safety architecture provides robust protection for stored samples for a minimum of 30 hours when faced with system failures or external power outages. This exceptional thermal holdover capacity offers a substantial time window for emergency procedures, backup power activation, or safe sample transfer, mitigating the risk of catastrophic sample loss.
