VWR VWR-HC-PL-49 Premium Series Laboratory Double Glass Door Refrigerator Variable Speed Compressor, ENERGY STAR, 49 cu. ft.

VWR VWR-HC-PL-49 Premium Series Laboratory Double Glass Door Refrigerator Variable Speed Compressor, Ultra-Quiet Operation, ENERGY STAR, 24V Battery Backup, 49 cu. ft.

The VWR Premium Series Laboratory Double Glass Door Refrigerator (Catalog No: 76919-380 / Model: VWR-HC-PL-49), supplied by VWR International, is an ENERGY STAR® certified, high-capacity 49 cubic foot (1388 L) vertical cold storage solution designed for demanding scientific, clinical, and industrial laboratory applications. Engineered with a hermetic Variable Speed Compressor (VSC) operating across a 1300 to 4000 rpm range, this unit dynamically self-adjusts to cooling demands to optimize energy consumption, accelerate pull-down times (70 minutes to nominal operating temperature), and deliver ultra-quiet operation (38 dBA or less).

Thermal management is controlled via a Proportional Integral Derivative (PID) microprocessor paired with a clear LCD display, providing precise temperature regulation across an adjustable range of 1°C to 10°C (nominal set point 4°C). Featuring patent-pending Forced Air circulation technology and zero-energy cycle defrosting, the unit maintains outstanding thermal consistency with ±1.2°C cabinet air uniformity, ±1.0°C stability, and a maximum temperature variation of ±1.6°C. Operational continuity is supported by a 24V high-capacity battery backup system that ensures uninterrupted controller operation, temperature monitoring data acquisition (DAQ), and alarm logging (up to 100 entries) during facility power interruptions. Data communication and exports are facilitated via an RS-485 (MODBUS) interface and an integrated USB port.

The cabinet interior provides extensive storage capacity equipped with ten adjustable shelves featuring rear guard rails, optional pull-out drawer integration, and full-coverage balanced-spectrum shielded LED lighting. System control is monitored via dual thermal probes placed inside a bottle filled with glass bead thermal media, while a rear-wall 3/4" port allows easy access for external validation probes.

Built with a durable white powder-coated steel exterior and EPA-compliant high-density foamed-in-place urethane insulation, the unit features double glass swing doors (right and left hinged) with key locks for enhanced security. Operating on eco-friendly, EPA SNAP-compliant R600a natural hydrocarbon refrigerant, the unit is ETL and C-ETL listed to UL471 standards. It comes backed by a 2-year parts and labor warranty and a 7-year compressor parts warranty.

Features:

• Variable Speed Compressor (VSC) Technology: Hermetic VSC adjusts compressor speed (1300–4000 rpm) dynamically to load demands, maximizing energy efficiency, extending system lifespan, and achieving a 70-minute pull-down time.
• ENERGY STAR® Certified Efficiency: Consumes only 1.47 kWh/day with a low average heat rejection of 465 BTU/hr, significantly exceeding standard Energy Star performance benchmarks.
• Ultra-Quiet Operation: Engineered with multi-speed fan control and sound suppression, delivering an operating noise level of 38 dBA or less.
• Large Capacity Double Glass Door Configuration: Generous 49 cu. ft. (1388 L) volume featuring two full-height glass swing doors (left and right hinged) with key locks.
• High Thermal Consistency & Forced Air Cooling: Patent-pending forced air circulation provides ±1.2°C cabinet air uniformity and ±1.0°C stability across all storage zones.
• PID Microprocessor Controller & LCD Display: Precise PID microprocessor temperature control with LCD display, switchable units, and 0.1°C display resolution across a 1°C to 10°C operating window.
• 24V Battery Backup & Advanced Alarm Suite: Keeps controller, data monitoring, and alarm logging (up to 100 events) active during power outages. Alarms include high/low temp, sensor failure, door ajar, power failure, and battery replacement.
• Data Transfer & Digital Connectivity: Outfitted with RS-485 (MODBUS) communication and a USB port for rapid data logging download and firmware updates.
• Versatile Interior Setup: Outfitted with 10 adjustable shelves with rear guard rails, optional pull-out drawer compatibility, shielded LED lighting, and a 3/4" rear probe access port.
• Eco-Friendly R600a Refrigerant & Warranty Protection: Runs on natural, EPA SNAP-compliant R600a hydrocarbon refrigerant. ETL listed, backed by a 2-year parts and labor warranty plus a 7-year compressor warranty.
