Upright Blood Bank Refrigerator with Chart Recorder

What is the Upright Blood Bank Refrigerator with Chart Recorder?

A floor-standing 2–6 °C refrigerator of about 300–1500 L for whole blood and red cell concentrates, fitted with a chart or electronic recorder and an independent alarm. It is used by hospital blood banks and transfusion laboratories that must document storage temperature.

Overview

Blood storage is governed by a narrow 2–6 °C window, so this variant uses tighter control than a pharmacy refrigerator, with temperature uniformity of 2 K or better. Air is circulated by fans through ducted shelves with racks or drawers sized for blood bags. A circular chart recorder or an electronic data logger provides a continuous record, and an independent probe in glycol drives a separate alarm circuit with battery backup. The cabinet has a glass door to allow checking the inventory without opening, a rear or side condenser and an internal light. Capacity ranges from 300 to 1500 L. A remote alarm contact can connect to a hospital monitoring system. Validation by temperature mapping, plus alarm challenge tests, is normally required at installation.

How does it work?

A laboratory blood bank refrigerator uses a vapour-compression circuit with forced-air circulation to hold a narrow temperature band. The cabinet has PU insulation, ducted shelves and a microprocessor controller that reads a control probe and cycles the compressor. A second, independent probe, often buffered in glycol, drives a separate alarm circuit with battery backup so that a control failure cannot go unnoticed. A chart recorder or electronic logger produces a continuous record. Air ducting and fan placement minimise cold spots near the evaporator to avoid freezing red cells and haemolysis. Units for samples and reagents can use a simpler undercounter design, while those for transfusion units need tighter uniformity, recording and validated alarm performance.

What are the key features?

• Tight 2–6 °C control with uniformity of about 2 K or better
• Circular chart recorder or electronic logger for continuous records
• Independent glycol-buffered alarm probe with battery backup
• Racks and drawers sized for blood bags with ducted air circulation
• Glass door for checking stock without opening

What are the technical specifications?

A typical upright blood bank refrigerator with chart recorder configuration offers temperature range of 2–6 °C, set point 4 °C, net volume of 300–1500 L, temperature uniformity of ≤ 2 K, recorder of Circular chart or electronic logger, alarm probe of Independent, glycol-buffered and battery backup of Alarm and controller, ≥ 24 h. 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 Upright Blood Bank Refrigerator with Chart Recorder is used in hospital blood banks, transfusion laboratories, blood collection centres and red cell concentrate storage. Across the wider Blood Bank Refrigerators class, laboratories also deploy it for retained patient samples, red cell storage and transfusion reagents.

Which standards and certifications apply?

Relevant standards and methods include AABB Standards for Blood Banks and Transfusion Services, Council of Europe Guide to the Preparation, Use and Quality Assurance of Blood Components, ISO 15189, IEC 61010-2-011 and IEC 61010-1. 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 on a level floor with the clearance stated in the manual, away from heat sources, and allow the cabinet to stabilise before loading. Perform installation, operational and performance qualification, including temperature mapping and alarm challenge tests, and repeat after relocation or major repair. Calibrate probes and recorders at least yearly against traceable references. Clean condensers, check gaskets and test battery backups on schedule. Keep records of temperatures, alarms and corrective actions as required by your accreditation body and transfusion regulator.

How do I select the right Upright Blood Bank Refrigerator with Chart Recorder?

Select this variant for whole blood and red cells that require documented 2–6 °C storage. Specify volume, recorder type, alarm probe, battery duration, remote contact and number of drawers or racks. A separate qualified plasma freezer is needed for frozen components unless the combination model is chosen.

How does it compare with other Blood Bank Refrigerators variants?

Decide first what will be stored. Samples and reagents suit 2–8 °C undercounter or benchtop units, red cell units need 2–6 °C upright cabinets with chart recorder and independent alarm, and plasma needs a freezer or a combined cabinet. Compare temperature uniformity (2 K or better for units), recording method, battery duration and alarm contacts. If several cabinets are operated, choose remote monitoring with audit trail. Match capacity to peak stock and allow for growth. Check that the ambient range and power supply suit your laboratory, and ask for mapping data from the manufacturer.
