Operating a refrigerated or frozen warehouse is expensive. Refrigeration power costs represent up to 60% of total operational expenditure, while every square meter of sub-zero floor space carries high construction and maintenance overheads. Selecting the right storage architecture is the single most critical decision for cold chain logistics leaders.
Traditional selective pallet racking requires multiple operating aisles for forklifts, resulting in up to 60% of expensive refrigerated air volume being wasted on empty aisle space. Drive-In racking improves density but introduces severe risks of forklift collision damage inside the cold room, slow pallet retrieval speeds, and limited FIFO (First-In, First-Out) control.
Remprack Cold Storage Radio Shuttle Racks solve these fundamental problems by creating a semi-automated, deep-lane storage system. Forklifts remain safely at the lane face, while self-propelled radio shuttle carts transport heavy pallet loads (up to 1,500 kg) along precision steel rails deep within storage channels up to 40 meters. By eliminating forklift aisles inside the freezer chamber, spatial utilization jumps from 40% to over 85%, cutting per-pallet energy consumption by up to 45%.
Engineered to withstand harsh condensation and sub-zero temperatures down to -30°C, Remprack provides specialized shuttle systems tailored to food processing, pharmaceutical cold chains, third-party logistics (3PL), and deep-freeze distribution centers.
Designed for perishable food, dairy, and meat processing facilities requiring strict First-In, First-Out expiration management. Forklifts load from the entry side while shuttles retrieve from the dispatch face.

Get CatalogAs global demand for fresh produce, biologics, prepared foods, and frozen pharmaceuticals surges, cold storage procurement strategies are undergoing a fundamental transformation. B2B buyers must account for evolving energy regulations and technological advances.
High labor turnover and harsh working conditions in sub-zero freezers make manual forklift driving unsustainable. Procurement managers are rapidly replacing traditional drive-in racks with radio shuttles and 4-way shuttle ASRS systems that reduce operator time inside freezer zones by up to 80%.
Escalating electricity tariffs globally mean that cold room operators can no longer afford wide forklift aisles. Deep-lane shuttle racking allows warehouses to increase pallet slot density per cubic meter, lowering the total kilowatts required to cool each pallet position.
Legacy lead-acid shuttle batteries suffer severe voltage drops in sub-zero chambers. Modern procurement contracts prioritize shuttles equipped with fast-charging Lithium Iron Phosphate (LiFePO4) power cells with built-in thermal jackets to guarantee 8 to 10 hours of continuous shift operation at -30°C.
Designing racking systems for sub-zero environments requires rigorous materials science and mechanical engineering. Remprack Storage Solutions Co., Ltd. continuously invests in technology R&D to overcome cold-room operational challenges.
Standard carbon steel becomes brittle and susceptible to fracture when subjected to freezing temperatures under dynamic load. Remprack manufactures cold-chain upright profiles using specialized Q355B cold-rolled steel tested via Charpy V-notch impact analysis to preserve ductility and structural integrity at -30°C.
Moving a shuttle car between ambient loading docks and freezer rooms causes rapid condensation buildup, which can short-circuit electronic control boards. Our cold room shuttles feature IP65-sealed control enclosures, internal anti-fogging heated lenses on optical sensors, and sealed bearings with synthetic sub-zero grease.
Modern cold room shuttles communicate via 5GHz Wi-Fi or RF modules directly to central Warehouse Management Systems (WMS). Operators can monitor battery health, track real-time pallet locations, auto-count stock, and execute automated maintenance alerts without entering the sub-zero room.
