VWR VWR-HC-SPL-23 Premium Series Laboratory Solid Door Refrigerator Variable Speed Compressor, ENERGY STAR, 23 cu. ft.

VWR Premium Series Laboratory Solid Door Refrigerator Variable Speed Compressor, ENERGY STAR, Ultra-Quiet Operation, PID Microprocessor Controller and LCD Display, 23 cu. ft.

The VWR Premium Series Laboratory Solid Door Refrigerator (Catalog No: 76919-386 / Model: VWR-HC-SPL-23), supplied by VWR International, is an ENERGY STAR® certified 23 cubic foot (651 L) high-performance vertical cold storage solution designed for temperature-sensitive scientific, biological, and clinical laboratory materials requiring a light-protected, fully insulated solid door enclosure. Powered by a hermetic Variable Speed Compressor (VSC) operating across a 1300 to 4000 rpm speed range, this unit automatically self-adjusts to dynamic thermal demands to optimize energy consumption, accelerate pull-down time (55 minutes to nominal operating temperature), and deliver ultra-quiet operational performance (35 dBA or less).

System temperature is regulated by a Proportional Integral Derivative (PID) microprocessor controller paired with a clear LCD display, offering precise thermal management across an adjustable temperature 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 outstanding thermal stability of ±0.6°C, thermal uniformity of ±0.6°C, and a maximum cabinet temperature variation of ±0.9°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. Digital communication and data extraction are facilitated via an RS-485 (MODBUS) interface and an integrated USB port for event logging export and software updates.

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

Constructed with a heavy-duty white powder-coated steel exterior and high-density EPA-compliant foamed-in-place urethane insulation, the unit features a single right-hinged solid swing door equipped with a key lock for security. 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 equipment service life, and 55-minute pull-down times.
• ENERGY STAR® Certified Efficiency: Consumes just 1.15 kWh/day with low average heat rejection (320 BTU/hr), significantly exceeding ENERGY STAR efficiency criteria.
• Ultra-Quiet Operation: Engineered specifically for noise-sensitive laboratory environments with an operational sound pressure level of 35 dBA or less.
• Insulated Solid Door Construction: Single right-hinged solid swing door provides thermal insulation and complete protection from ambient light exposure for sensitive samples.
• Superior Thermal Uniformity & Stability: Patent-pending forced air circulation achieves ±0.6°C cabinet air uniformity and ±0.6°C stability across all storage levels.
• 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 window.
• 24V Battery Backup & Advanced Alarm Suite: 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 Communication & USB Data Transfer: RS-485 (MODBUS) interface and integrated USB port allow easy temperature data extraction and firmware updates.
• Versatile Interior Layout: Equipped with 5 adjustable shelves featuring rear guard rails, optional pull-out drawer capability, 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.
