VWR Combination Laboratory Refrigerator and Freezer Unit Variable Speed Compressor, Dual Defrost Systems, 36-Hour Battery Backup and Alarm System 16 cu. ft. (13 cu. ft. Frg / 3 cu. ft. Frz)
The VWR Combination Laboratory Refrigerator and Freezer Unit (Catalog No: 77148-140 / Model: VWR-HC-RFC-16A), supplied by VWR International, is a dual-chamber cold storage solution providing a total volume of 16 cubic feet (453 L total: 13 cu. ft. / 368 L refrigerator and 3 cu. ft. / 85 L freezer). Designed for medical, scientific, and industrial research applications, this dual-zone system features independent temperature zones powered by a variable speed compressor (VSC operating between 1300–4000 rpm) for the refrigerator compartment, delivering optimal energy savings, rapid recovery, and precise thermal control.
The system is equipped with dual XRi77CH microprocessor controllers with bi-colored LED displays (0.1°C resolution, switchable °C/°F) for separate management of each chamber. The upper refrigerator operates within a 1°C to 10°C window (set point 5°C) using forced draft air circulation and zero-energy cycle defrost, achieving extraordinary performance with ±0.22°C uniformity, ±0.48°C stability, and ±0.71°C maximum temperature variation. The lower freezer operates within a -35°C to -15°C range (set point -33°C) with auto-defrost capability, maintaining ±0.69°C uniformity, ±1.14°C stability, and ±1.95°C maximum variation. Operational security is maintained via a 12V high-capacity battery backup that keeps controllers, data acquisition (DAQ), and alarm logging active for up to 36 hours during power interruptions. Digital connectivity is provided through an RS-485 (MODBUS) interface.
The interior layout features three adjustable vented stainless steel shelves in the refrigerator chamber and one fixed shelf in the freezer chamber, illuminated by a 12V LED light bar in the refrigerator. Each chamber includes an independent 3/8" probe access port and two controller probes (one air probe and one in a sample bottle).
Built with a Bioscience Grey powder-coated canopy, white textured chamber exterior, and foamed-in-place high-density urethane insulation, the unit features two solid right-hinged swing doors with key locks. Operating on eco-friendly EPA SNAP-compliant R600a natural hydrocarbon refrigerant, the unit is ETL/cETL listed and certified to UL 471 and CSA C22.2#120 standards. It comes backed by a 2-year parts and labor warranty and a 7-year compressor parts warranty.
Features:
- Dual-Zone Variable Speed Compressor Technology: Refrigerator compartment utilizes a hermetic variable speed compressor (1300–4000 rpm) to maximize energy efficiency, accelerate pull-down times (40 min frg / 165 min frz), and ensure uniform cooling.
- Independent Microprocessor Controllers: Dual XRi77CH microprocessor controllers with bi-colored LED displays provide precise, independent set-point selection, touchpad controls, and resettable 1-point min/max history.
- Exceptional Thermal Performance: Refrigerator chamber delivers ±0.22°C air uniformity and ±0.48°C stability; freezer chamber delivers ±0.69°C uniformity and ±1.14°C stability.
- Dual Defrost Systems: Cycle-optimized zero-energy defrost for the refrigerator to prevent thermal spikes, paired with an auto-defrost system for low-maintenance freezer operation.
- 36-Hour Battery Backup & Alarm System: Integrated 12V battery backup keeps controllers, alarms (high/low temp, door ajar, sensor failure, power loss), DAQ monitoring, and remote alarm contacts active for 36 hours during outages.
- Digital Communication & Access: RS-485 (MODBUS) connection for remote monitoring and data logging, plus dual 3/8" rear probe access ports (one for each chamber).
- High-Quality Interior Architecture: Refrigerator includes 3 adjustable vented stainless steel shelves and 12V LED light bar; freezer includes 1 fixed shelf.
- Durable & Secure Enclosure: Bioscience Grey powder-coated canopy with white textured exterior, key-locked double solid swing doors (right hinged), and leveling legs.
- Eco-Friendly R600a Refrigerant & Warranty Protection: Employs natural, EPA SNAP-compliant R600a hydrocarbon refrigerant. Backed by a 2-year parts and labor warranty and a 7-year compressor warranty.
