To balance performance with sustainability, the TSX505SA incorporates Thermo Scientific’s V-drive technology, which continuously adapts operation based on real-world usage patterns. The system actively responds to changes such as door openings and loading events, maintaining uniform conditions while reducing unnecessary energy use during stable periods. Unique to this model, a dual refrigeration solution uses two synchronized solid-state heat pumps that combine cold wall cooling with fan-assisted recovery. This design helps minimize temperature fluctuations commonly associated with traditional cycling compressor systems.
User-focused controls and monitoring features further enhance day-to-day operation. A touchscreen controller with password protection provides secure access to settings and system status. Integrated datalogging with USB download supports documentation and compliance requirements, while audible and visual alarms alert users to power interruptions, temperature deviations, door ajar events, and system conditions. With its compact undercounter footprint and advanced refrigeration design, the TSX505SA delivers reliable performance for critical laboratory cold storage applications.
All of our equipment is fully tested to perform at factory specifications before being shipped.
