Labotemp 2°C to 8°C Portable Pharmacy Refrigerator PHR-23 provides dependable cold storage for vaccines, insulin, pharmaceuticals, biological reagents, diagnostic kits, and other temperature-sensitive medical products. Designed as a compact small pharma refrigerator and medical refrigerator, it features a 25 L storage capacity, precise temperature range from 2°C to 8°C, and ±1°C temperature stability to protect valuable medical supplies during storage and transportation. The gravity-driven thermosiphon heat transfer system, high-performance polyurethane insulation, and precision PT100 temperature sensor maintain uniform chamber temperatures, while compatibility with 100–240 V AC and 12–24 V DC power enables reliable operation in hospitals, pharmacies, vaccination clinics, ambulances, mobile healthcare units, and field laboratories.
Advanced Stirling Cooling Technology
The refrigerator utilizes a free-piston Stirling cooling engine, where sealed helium gas repeatedly compresses and expands within the cooling system to remove heat efficiently without relying on a conventional compressor. This innovative refrigeration technology produces minimal vibration, quieter operation, and fewer moving mechanical parts, helping reduce maintenance while improving long-term reliability. The system cools from 25°C to 2°C in approximately 30 minutes and consumes only 15 W during steady-state operation, making it an energy-efficient solution for continuous medical storage. A lockable lid, manual defrost, high and low temperature alarms, durable insulated construction, and precise temperature control ensure safe and consistent protection of temperature-sensitive pharmaceuticals.
