MORTUARY SYSTEMS – WHAT ARE THEY?
Mortuary systems are specialized refrigeration systems designed to preserve deceased individuals under hygienic, safe, and controlled temperature conditions until burial, transportation, autopsy, or forensic examination processes are completed. Mortuary systems are among the technically advanced cold storage solutions used in hospitals, municipalities, forensic medicine institutions, funeral service organizations, private healthcare facilities, military installations, and large-scale public buildings.
Modern mortuary systems consist of more than just a refrigeration cabinet. The system includes stainless steel mortuary cabinets, body storage chambers, refrigeration units, evaporators, condensers, compressor systems, automation panels, temperature control devices, hygienic surface coatings, drainage systems, and, when required, ventilation equipment. All these components are designed to maintain the desired temperature within the mortuary room while ensuring sustainable hygienic conditions.
Mortuary systems are of great importance for public health and environmental safety. Professional design of mortuary refrigeration systems is essential to slow down the biological decomposition process after death, prevent unpleasant odors, ensure hygienic preservation conditions, and facilitate proper forensic procedures. A properly designed mortuary system enables healthcare institutions and funeral service providers to operate safely, systematically, and in compliance with applicable standards.
HOW DO MORTUARY SYSTEMS WORK?
Mortuary systems operate on the principle of controlled preservation at low temperatures. The primary objective of mortuary refrigeration systems is to slow the biological decomposition process by maintaining the deceased within a specific temperature range. This process is achieved through a refrigeration cycle. The compressor, evaporator, condenser, expansion device, and refrigerant work together to transfer heat from the mortuary cabinet or mortuary room to the outside environment.
In mortuary systems, the evaporator absorbs heat from the air inside the cabinet or room. The compressor compresses the low-pressure refrigerant gas into a high-pressure state. The condenser rejects this heat to the outside environment, causing the refrigerant to return to a liquid state. The expansion valve then reduces the pressure, allowing the cycle to restart. Through this cycle, a constant temperature is maintained within the mortuary cabinet or room.
Temperature control is critical in mortuary systems. In standard body preservation systems, temperatures are generally maintained between +2°C and +6°C. Lower temperatures may be preferred for long-term storage or special forensic applications. Digital thermostats, PLC control systems, and alarm systems continuously monitor temperature deviations. This ensures that the mortuary system operates under constant supervision while maintaining hygienic preservation conditions.
WHAT ARE THE TYPES OF MORTUARY SYSTEMS?
Mortuary systems are classified into different categories based on application area, capacity, operating temperature, and project design requirements. The most commonly used mortuary systems include single-body mortuary cabinets, multi-body mortuary cabinets, modular mortuary systems, walk-in mortuary rooms, stainless steel mortuary chambers, forensic mortuary systems, and mobile mortuary systems.
Single-body mortuary cabinets are preferred in small healthcare centers, private clinics, and facilities with low-capacity requirements. Mortuary cabinets with capacities of two, three, four, six, or more bodies are commonly used in hospitals, municipalities, and funeral service organizations. These systems provide separate drawer or shelf compartments for each body.
Walk-in mortuary systems are implemented in facilities requiring larger storage capacities. In these systems, an entire room is designed as a refrigerated body storage area. Modular mortuary systems feature panelized construction and can be expanded according to future requirements while offering rapid installation. Forensic mortuary systems are specialized applications requiring higher levels of hygiene, security, record management, and access control. When selecting a mortuary system, factors such as capacity, frequency of use, hygiene requirements, room dimensions, and refrigeration performance must be considered.
