20 Units of S13-1600kVA/13.8kV Transformers for a Cold Storage Warehouse in the USA
Project Overview
HBTP supplied 20 units of S13-1600/13.8 transformers for a large-scale refrigerated cold storage and distribution warehouse in Chicago, USA. The project represents a significant deployment in the cold storage logistics sector, requiring transformers engineered for reliable operation under demanding conditions.
Project Background
This cold storage facility maintains temperatures from -25°C to +5°C across multiple zones for frozen and refrigerated food storage. With over 100,000 pallet positions, refrigeration accounts for 70% of the electrical load, making power reliability critical to prevent product loss.
Customer Requirements
US-standard 13.8kV/480V transformers, 1600kVA capacity, S13 efficiency, design for continuous high refrigeration load, N+1 redundancy for temperature-critical operations, compliance with IEEE C57.12 and NEC, and UL listing.
Our Solution
HBTP supplied its S13-series transformers, engineered specifically for cold storage logistics applications. The high-quality CRGO silicon steel core with step-lap mitered joints minimizes no-load losses, while copper windings provide enhanced short-circuit withstand capability and long service life.
