Proprietary temperature monitoring system employed by The Frozen Food Courier for continuous tracking of cold chain conditions throughout delivery operations. Cold Watch provides real-time temperature data, immediate alerts when temperatures…
Compressor Cycling
On/off operational pattern of fixed-speed compressors that wastes 25-35% energy through startup surges and inability to match partial loads, causing 20-40 daily cycles in courier operations.
Cross-Docking (Cold Chain)
A logistics strategy where incoming frozen or chilled products are immediately transferred to outbound vehicles with minimal or no storage time, reducing handling costs and maintaining temperature integrity. Products move…
Defrost Cycle
The periodic process in refrigeration systems where heating elements melt ice accumulation on evaporator coils to maintain cooling efficiency. Traditional timer-based defrost cycles activate at fixed intervals regardless of actual…
Delivery Window
The scheduled time period during which courier operations plan to complete a specific delivery, balancing customer convenience with operational efficiency. Delivery windows in frozen food logistics must account for route…
Demand-Based Defrost
Advanced defrost control that initiates cycles based on measured system conditions rather than fixed timers, reducing fuel consumption 20-30% through intelligent activation.
Design Temperature
Extreme temperature condition for equipment sizing – industry uses 32-35°C European standards for 42°C South African urban conditions plus altitude effects, ensuring summer failures.
Direct-to-Consumer (D2C) Frozen Delivery
See: Last-Mile Cold Chain Delivery Business model where frozen food producers or platforms deliver directly to consumers’ homes, bypassing traditional retail distribution. Requires specialized last-mile logistics infrastructure maintaining cold chain…
Door Openings (Thermal Load)
The heat infiltration and temperature disruption caused by opening refrigerated cargo spaces during multi-stop delivery operations. Each door opening introduces warm ambient air, humidity, and radiant heat from surrounding surfaces,…
Dry Ice
Solid carbon dioxide (CO2) at -78.5°C used as a passive cooling method for short-duration frozen food transport. Dry ice sublimates directly from solid to gas without liquid phase, eliminating moisture…
