Helmer Scientific iUF freezers are single door -86°C ultra-low temperature freezers designed and developed to deliver world-class temperature performance for the storage of samples, reagents, controls, tissue, rare blood, and other biological materials.

Powered by OptiCool™ Cooling Technology, the iUF freezers utilise variable capacity compressors, natural hydrocarbon refrigerants, innovative oil management, and frost control to provide world-class cooling performance, increased energy efficiency and sustainability, and quieter operation compared to traditional ultra-low temperature freezer technology.

• OptiCool™ Cooling Technology with variable capacity compressors and natural hydrocarbon (HC) refrigerants optimises temperature performance, noise management, and energy management
• HC refrigerants support sustainability: reduce heat output, decrease carbon footprint, lower global warming potential grade (GWP), and have no impact on ozone depletion
• Designed to meet EnergyStar® standards for efficiency
• EPA SNAP-compliant refrigerants and foaming agents
• Unique Heat Barrier System™ keeps heat out and reduces frost. Includes four levels of containment: fortified outer door with multi-bulb gaskets, insulated and reinforced inner door with dual-blade gaskets, hot gas loop and advanced composite panels in cabinet frame, and premium insulation
• Custom cascade refrigeration system designed to provide maximum heat exchange and optimize oil management
• Innovative i.C3® Information Centre provides intelligent diagnostic information and temperature data, while providing security features to keep information safe
• Guardian Plus™ Access Control ensures product integrity
