Single-Door Upright Pharmacy Refrigerator

What is the Single-Door Upright Pharmacy Refrigerator?

A floor-standing single-door refrigerator of roughly 300–500 L that holds 2–8 °C for medicines, biologicals and reagents. It is the standard choice for hospital pharmacies, dispensaries and departmental stores where a balance of capacity, footprint and temperature stability is needed.

Overview

The single-door upright is the most common pharmacy format, with 300–500 L of net volume, 4–6 adjustable shelves and a glass or solid door. Forced-air circulation with a ducted or rear evaporator limits temperature differences inside the cabinet to about 2–3 K under normal loading. Controllers provide set-point adjustment, alarm thresholds, a delay before the door-ajar alarm, and often a USB or RS-485 interface for records. Heated glass doors reduce condensation, and LED interior lighting lowers heat input. The compressor and condenser sit at the base or top of the cabinet. Castors allow positioning, and levelling feet hold the unit steady. Shelf spacing is adjustable to fit vials, boxes and drawer baskets, and a backup battery for the alarm is common.

How does it work?

A pharmacy refrigerator removes heat from an insulated cabinet with a vapour-compression circuit: a compressor, condenser, expansion device and evaporator circulate refrigerant, typically R600a, R290 or R134a. A fan moves air over the evaporator and through the cabinet, which equalises temperature and speeds recovery after door opening. A microprocessor controller reads an air or buffered probe and cycles the compressor around the set point, normally 5 °C. Independent sensors drive high and low alarms, door-ajar warnings and power-failure alerts. Insulation of polyurethane foam, a sealed door gasket and, in some models, a heated glass door limit heat gain and condensation. Data loggers record temperature for audit. Performance is judged by uniformity, stability, recovery time and hold-over during power loss.

What are the key features?

• Net volume of 300–500 L with 4–6 adjustable shelves
• Forced-air circulation limits internal temperature spread to about 2–3 K
• Heated glass door reduces condensation and allows stock viewing without opening
• Alarm set with door-ajar delay, sensor fault and battery backup
• USB or RS-485 output for temperature records
• Castors and levelling feet for positioning

What are the technical specifications?

A typical single-door upright pharmacy refrigerator configuration offers temperature range of 2–8 °C, net volume of 300–500 L, temperature uniformity of ≤ 3 K at 5 °C set point, cooling method of Forced-air circulation, refrigerant of R600a or R290 and shelves of 4–6 adjustable, coated wire. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Single-Door Upright Pharmacy Refrigerator is used in hospital pharmacy, dispensary stock storage, biological product storage and departmental reagent storage. Across the wider Pharmacy Refrigerators class, laboratories also deploy it for hospital pharmacy stock, vaccine storage and insulin and biologics.

Which standards and certifications apply?

Relevant standards and methods include WHO PQS E003 refrigerators and freezers, WHO Good Distribution Practices for pharmaceutical products (TRS 957 Annex 5), EU GDP Guidelines 2013/C 343/01, USP <1079> Good Storage and Distribution Practices, IEC 61010-1 and ISO 13485. Certification candidates for this model are CE, ISO 9001 manufacturing and ISO 13485 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Install the cabinet on a level floor away from heat sources and direct sunlight, leaving the ventilation clearance in the manual, and let it stabilise for several hours before loading. Validate the cabinet by temperature mapping at empty and loaded conditions, and calibrate probes against a traceable reference at least annually. Clean the condenser every few months, check door gaskets and verify alarms regularly. Keep stock away from the evaporator outlet. Retain temperature records and excursion reports for the period required by your regulator. Good practice guidance, such as WHO and national pharmacy rules, sets expectations for monitoring and response.

How do I select the right Single-Door Upright Pharmacy Refrigerator?

Choose a single-door upright for 300–500 L of stock in a medium-traffic pharmacy. Specify volume, uniformity requirement, door type, interface needs, ambient range and alarm contacts in the RFQ. Move to a double-door model when stock exceeds about 500 L, or to a vaccine model if validated holding time and remote monitoring are required.

How does it compare with other Pharmacy Refrigerators variants?

Start from what is stored and how much. Small volumes of routine medicines fit an undercounter unit, typical dispensary stock fits a single-door upright, and central stores need a double-door cabinet. Vaccines call for a dedicated model with buffered probe, data logging and verified hold-over time. Consider uniformity (about 3 K or better), recovery after door opening, alarm set, interface to monitoring systems and door type. Check whether the refrigerant and energy use match local rules, and confirm the ambient temperature range, since a cabinet rated for 32 °C may struggle in a hot storeroom. Combination units suit small sites with frozen items.
