Standardized shipping container (typically 20ft or 40ft) with integrated refrigeration unit, used for sea, rail, and intermodal transport.
Refrigerant
Working fluid in a refrigeration system that absorbs heat by evaporating at low temperature/pressure and rejects heat by condensing at high temperature/pressure.
Refrigeration Cycle
The continuous process by which a refrigeration system removes heat from a low-temperature space and rejects it to a higher-temperature environment.
Refrigeration Technician Certification
Definition: Professional qualification for refrigeration and air conditioning technicians, demonstrating competence in installation, maintenance, and repair of refrigeration systems. Why It Matters: Qualified technicians ensure system reliability and safety. Regulatory requirements for handling refrigerants. Insurance and warranty implications. SAIRAC registration demonstrates professional standing. South African Qualifications:– Trade Certificate: Refrigeration Mechanic (Red Seal)– National Certificate: Refrigeration (NQF levels)– SAIRAC Professional Registration–…
Relative Humidity (RH)
The amount of moisture in air expressed as a percentage of the maximum moisture the air can hold at that temperature. 100% RH = saturation (condensation begins).
RTD (Resistance Temperature Detector)
High-accuracy temperature sensor using metal resistance wire (typically platinum) whose electrical resistance changes predictably with temperature.
SABS (South African Bureau of Standards)
Definition: South African Bureau of Standards. The national standards body responsible for developing, publishing, and promoting South African National Standards (SANS). Also provides testing, certification, and training services. Why It Matters: Compliance with SANS demonstrates quality and safety. Some SANS are mandatory; others voluntary. SABS Mark is recognized indicator of quality for equipment and materials. SABS Services:– Standards Development: SANS…
SADC Cold Chain Standards
Definition: Proposed regional cold chain standards under development by the Southern African Development Community (SADC) to harmonize cold chain requirements across member states and facilitate cross-border trade in perishable goods. Why It Matters: Harmonized SADC standards would simplify cross-border cold chain operations, reduce trade barriers, and improve food safety across the region. South African cold chain operators would benefit from…
SAHPRA (South African Health Products Regulatory Authority)
South African regulatory authority for medicines, medical devices, and in-vitro diagnostics. Enforces GDP (Good Distribution Practice) requirements for pharmaceutical cold chain.
