The Stirling Ultracold SU780XLE -86C Upright Ultra-Low Freezer is at the forefront of ultra-low temperature (ULT) freezer technology, offering an unparalleled temperature range of -20°C to -86°C, adjustable in 1°C increments. This freezer stands out with its industry-leading steady-state temperature variation of ± 1°C over time and an impressive 35-minute door opening recovery time to -80°C within ± 1°C of the setpoint, as per the ENERGY STAR Final Test Method. It is equipped with connectivity options for Building Management Systems (BMS)/Building Automation Systems (BAS) or third-party monitoring systems, alongside a real-time temperature display for constant monitoring. With a voluminous 780L capacity in a compact design, the SU780XLE offers the largest storage capacity per square foot of floor space in its class, accepting universal power sources for versatile installation. Its modulated cooling capacity and 100% adaptive control ensure faster temperature pull-down and recovery times, while the advanced Stirling engine technology employs only two moving parts, eliminating the need for compressors and significantly reducing the risk of failure.

The SU780XLE is not only a powerhouse in protecting research materials but also champions environmental sustainability. It consumes up to 70% less energy than traditional compressor-based units and 45% less than similar-sized ENERGY STAR rated freezers, utilizing EPA SNAP-approved 100% natural refrigerants and environmentally friendly manufacturing processes. This results in a significantly smaller carbon footprint. Economically, the freezer is designed to protect your operating budget by offering up to 70% reduction in electric utility costs compared to legacy freezers, alongside minimized heat output and HVAC operation costs. It reduces the need for extensive floor space, infrastructure, and backup power, all while maintaining the lowest ongoing maintenance and service costs. With its manual defrost method, helium-charged free-piston Stirling cooling engine, and gravity-driven thermosiphon heat transport system, the SU780XLE is a smart choice for research organizations seeking reliability, efficiency, and environmental responsibility.
