Refrigerated Storage Containers – Reefers

Refrigerated storage containers, commonly known as reefers, are temperature-controlled units designed for the storage and transport of goods requiring a stable, chilled, or frozen environment. They are actively cooled using an integral refrigeration system, making them distinct from insulated containers which lack a powered cooling unit .

Key Features

• Active Temperature Control: Integrated refrigeration unit provides precise temperature management, typically ranging from -35°C to +30°C to accommodate a variety of products .

• Superior Insulation: Walls, ceiling, and floor are fitted with high-performance insulation to minimize heat transfer and maintain internal temperatures efficiently .

• Advanced Air Circulation: A T-bar flooring system and forced-air fans ensure cold air circulates uniformly around palletized cargo, preventing hotspots and maintaining product integrity .

• Hygienic Interior: Interior is typically lined with stainless steel or food-grade aluminum, providing a durable, corrosion-resistant, and easy-to-clean surface .

• Robust Construction: Built with a durable steel or aluminum outer shell to withstand the demands of transport and outdoor storage .

• Data Logging: Features microprocessor-based controls for precise monitoring, data logging, and alarm functions .

Detailed Description

Reefer containers are constructed to be both wind and watertight, with a two-layered vacuumed wall structure that creates a highly effective thermal barrier . The heart of the system is the refrigeration unit, which operates on a three-phase electrical power supply. It uses a vapour-compression cycle to cool the air, which is then circulated through the container .

The primary purpose of a reefer is to provide a stable, predetermined environment for temperature-sensitive goods, protecting them from spoilage and degradation . They are widely used for both active shipping and as a cost-effective, versatile alternative to constructing permanent cold storage facilities on-site .
