Containerized Ammonia Refrigeration System for a Freezer Warehouse

Advanced Technology and Waste Heat Utilization for Temperature Control and Energy Efficiency

Project Overview

Our team at ADEAREST successfully delivered a comprehensive refrigeration solution for a freezer warehouse in the logistics industry. We proudly designed, supplied, installed, and commissioned a containerized ammonia refrigeration system, ensuring optimal temperature control for both the freezer and loading areas.

Scope of Work

This project required the supply and installation of an insulated containerized ammonia plant room adjacent to a freezer warehouse. The plant room housed an ammonia compressor rack, an ammonia separator with accessories, ammonia pumps with valve stations, and a chilled water cooler for plant room cooling. We also installed an ammonia leak detection system with ventilation fans, control and starter panels, a complete set of controls, cabling and wiring, and lighting for the plant room. The system featured ammonia coolers for the freezer room and chilled water coolers for the loading area, with interconnecting ammonia and chilled water piping. A glycol underfloor heating system was installed, utilizing retardant (waste) heat from the refrigeration system. Electrical control panels and related wiring were supplied and installed in the warehouse, with system operation visualized in the control room. The ADEAREST team demonstrated a comprehensive system start-up and thorough commissioning before handing over the project.

Technical Highlights

The ammonia compressor rack featured a screw-type compressor and NH3 refrigerant. Ammonia air coolers were installed in the freezer room, while chilled water air coolers served the loading area. The system utilized high-quality materials for all vessels and piping, adhering to ASTM or DIN standards. A glycol underfloor heating system was implemented to provide thermal protection and prevent ground freezing by utilizing the retardant heat from the refrigeration system.

Project Success

This state-of-the-art ammonia refrigeration system meets the stringent requirements of the logistics industry. Our client can now maintain precise temperature control in both freezer and loading areas, ensuring the integrity of stored products. The project is a testament to ADEAREST's expertise in delivering customized, high-performance refrigeration solutions.
