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

VWR VWR-HC-SPL-49 Premium Series Laboratory Double Solid Door Refrigerator Variable Speed Compressor, PID Microprocessor Controller and LCD Display ENERGY STAR, 49 cu. ft.

The VWR Premium Series Laboratory Double Solid Door Refrigerator (Catalog No: 76919-388 / Model: VWR-HC-SPL-49), supplied by VWR International, is an ENERGY STAR® certified, high-capacity 49 cubic foot (1388 L) vertical cold storage solution designed for temperature-sensitive biological, scientific, and clinical laboratory materials requiring maximum thermal insulation and full ambient light protection. Powered by a hermetic Variable Speed Compressor (VSC) operating across a 1300 to 4000 rpm speed range, this unit automatically self-adjusts to cooling demands to minimize energy consumption, accelerate pull-down times (70 minutes to nominal operating temperature), and ensure ultra-quiet operational performance (38 dBA or less).

System temperature is regulated by a Proportional Integral Derivative (PID) microprocessor controller paired with an LCD display, delivering precise thermal management across an adjustable range of 1°C to 10°C (factory default set point 4°C). The patent-pending Forced Air circulation system, combined with zero-energy cycle defrosting, achieves exceptional thermal stability of ±1.0°C, thermal uniformity of ±1.2°C, and a maximum cabinet temperature variation of ±1.6°C. System monitoring and data integrity are supported by a 24V high-capacity battery backup that maintains active temperature monitoring, data acquisition (DAQ), and alarm logging (last 100 entries) during facility power outages. Communication and data transfer are supported via an RS-485 (MODBUS) connection and an integrated USB port for event logging export and software updates.

The interior cabinet features full-coverage, balanced-spectrum shielded LED lighting, ten adjustable steel shelves with rear guard rails, optional pull-out drawer capability, and a rear-wall 3/4" probe access port for external sensors. Thermal monitoring is driven by dual probes housed in a thermal media bottle filled with glass beads.

Constructed with a durable white powder-coated steel exterior and high-density EPA-compliant foamed-in-place urethane insulation, the unit features double solid swing doors (left and right hinged) with key locks for enhanced access control. Mounted on four preinstalled swivel casters (front locking casters), the unit operates on eco-friendly EPA SNAP-compliant R600a natural hydrocarbon refrigerant. Certified to UL471 standards, ETL listed, C-ETL listed, and ENERGY STAR certified, this refrigerator is backed by a 2-year parts and labor warranty plus a 7-year compressor parts warranty.

Features:

• Variable Speed Compressor (VSC) Technology: Hermetic VSC self-adjusts speed (1300–4000 rpm) to dynamic thermal loads, delivering maximum energy savings, extended service life, and 70-minute pull-down times.
• ENERGY STAR® Certified Efficiency: Consumes just 1.47 kWh/day with low average heat rejection (465 BTU/hr), significantly exceeding ENERGY STAR energy efficiency requirements.
• Ultra-Quiet Operation: Engineered for noise-sensitive laboratory environments with an operational sound pressure level of 38 dBA or less.
• Double Solid Door Enclosure: Two full-height solid swing doors (left and right hinged) provide superior thermal retention and total protection against light degradation for sensitive samples.
• Superior Thermal Uniformity & Stability: Patent-pending forced air circulation achieves ±1.2°C cabinet air uniformity and ±1.0°C stability across all storage zones.
• PID Microprocessor Controller & LCD Display: Advanced PID control system with intuitive LCD interface, switchable temperature scales, and 0.1°C display resolution across a 1°C to 10°C operating range.
• 24V Battery Backup & Comprehensive Alarms: Keeps controller, data logging, and alarm functions (power failure, temp sensor failure, battery monitor, high/low temp, door ajar) active for up to 100 logged events during outages.
• Digital Connectivity & USB Data Transfer: RS-485 (MODBUS) interface and integrated USB port enable rapid temperature data extraction and firmware updates.
• Versatile High-Capacity Interior: Equipped with 10 adjustable shelves featuring rear guard rails, optional pull-out drawer integration, shielded LED lighting, and a 3/4" rear probe access port.
• Eco-Friendly R600a Refrigerant & Extended Warranty: Runs on natural, EPA SNAP-compliant R600a hydrocarbon refrigerant. ETL listed, supported by a 2-year parts and labor warranty plus a 7-year compressor warranty.
