VWR VWR-HC-RFP-20 Standard Series Solid Door Laboratory Refrigerator, Cycle Defrost, Swing Door, 20 cu. ft., Dual Probe Safety Monitoring

The VWR Standard Series Solid Door Laboratory Refrigerator (VWR-HC-RFP-20) delivers dependable, energy-efficient, and cost-effective cold storage tailored for routine sample, media, and reagent holding. Engineered with a spacious 20 cubic foot (566 L) capacity, this upright laboratory refrigerator seamlessly balances professional cooling performance with a budget-conscious design, making it an ideal choice for daily scientific, clinical, and industrial workflows.

Constructed for indoor use in controlled laboratory environments ranging from +18°C to +26°C with less than 70% relative humidity, the unit features a durable white powder-coated steel exterior. Its single right-hinged solid swing door is insulated with EPA-compliant, foamed-in-place high-density urethane foam and seals tightly with a positive magnetic gasket. This robust insulation ensures maximum thermal retention, isolating sensitive materials from external room temperatures and ambient light. For enhanced security and controlled substance management, a physical keyed door lock is integrated directly into the door assembly to prevent unauthorized access.

The interior layout is optimized for organized, high-density storage. It features five adjustable wire shelves (composed of 4 full shelves and 1 half shelf) that allow users to customize space according to inventory needs. The unit comes equipped with adjustable leveling legs to ensure a perfectly stable installation on standard laboratory floors, and a 3/4" diameter rear wall access port that facilitates the introduction of external temperature monitoring probes without altering the cabinet wall.

Operational parameter monitoring is handled by a precise microprocessor temperature controller operating within an adjustable range of 1°C to 10°C. System status and sample temperatures are clearly displayed on an external digital screen, which allows users to switch between Celsius and Fahrenheit. A heavy-duty forced-draft air circulation system continuously drives cold air throughout the entire cabinet, eliminating hot spots and ensuring outstanding temperature uniformity alongside rapid thermal recovery after routine door openings.

Dual temperature tracking probes—one positioning an air temperature sensor and the other embedded in a simulated product sample bottle—provide high-accuracy operational monitoring. An integrated alarm system safeguards valuable biological inventory by delivering immediate audible and visual alerts for high/low temperature breaches, power disruptions, and sensor errors. State-switching remote alarm contacts are also built-in, enabling swift integration into centralized building management systems (BMS).

This eco-conscious refrigerator operates on natural R600a hydrocarbon refrigerant, ensuring optimal energy efficiency, lower utility expenses, and a minimal environmental footprint.

Features:

• Microprocessor Temperature Management: High-precision microprocessor controller maintains stable temperatures inside the cabinet within a flexible range of 1°C to 10°C, switchable between °C and °F.
• Forced-Draft Air Circulation: Internal fan-driven airflow dynamics guarantee superb uniform cooling across all shelves and enable rapid temperature recovery after door openings.
• Dual Probe Safety Monitoring: Employs two independent probes (one measuring cabinet air temperature and one inside a simulated sample bottle) to closely track real product conditions.
• Comprehensive Integrated Alarms: Provides instant audible and visual alerts for high/low temperature shifts, sensor failures, and power disruptions to prevent sample degradation.
• Remote Alarm Integration: Features state-switching remote alarm contacts to allow direct connection with external facility monitoring networks and automation systems.
• Secured Solid Door Access: Built with a single right-hinged solid door equipped with a heavy-duty handle and integrated physical keyed lock to control access to sensitive inventory.
• Eco-Friendly R600a Refrigerant: Utilizes natural hydrocarbon R600a refrigerant, offering an energy-efficient cooling system that meets global eco-friendly standards.
• Flexible Shelf Customization: Contains five sturdy wire shelves (4 full and 1 half shelf) that adjust easily to accommodate vials, media bottles, and large containers.
• Seamless External Probing: Includes a pre-drilled 3/4" diameter rear wall access port for running independent thermocouple lines or data loggers into the chamber.
• Robust Structural Insulation: Cabinet and door are fully insulated with foamed-in-place high-density urethane foam to maintain reliable thermal holdover.
