Cold Storage CO2 Case Study

Comprehensive Services for Transcritical CO2 Cold Storage and Freezer Facility

A pet food manufacturer faced a storage space shortage for both raw materials and finished products at one of its U.S. manufacturing plants. To address this, the company opted to build an 824,000-square-foot distribution and CO2 cold storage facility nearby.

The Problem:

The pet food manufacturer faced three primary challenges:

1. They needed help designing and managing the distribution and cold storage facility‘s 120,00 square-foot freezer, with space for nearly 15,000 pallets, and a 12,000 square-foot refrigerated cold dock.

2. The project had to meet federal, state, and local regulations, adhere to AIB food standards, and conform to FM Global design guidelines.

3. Implementing energy-efficient measures and selecting refrigerants with a low global warming potential (GWP) was imperative to decrease greenhouse gas emissions, supporting the company’s ambitious objective of slashing emissions by 50% by 2030.

Project Objectives:

  • Turnkey Refrigeration and Controls Design
  • Freezer Slab Frost-Heave Prevention Design
  • End-to-End Project Management
  • Startup, Testing and Commissioning
  • Ongoing Preventative Maintenance

The Solution:

CoolSys leveraged its teams of professional engineers, program managers, sustainability experts, and system installation, startup and maintenance teams to tailor a comprehensive solution that solved each of the customer’s problems.

CoolSys Energy Design (CED) engineered the freezer and cold dock to safely move and store raw materials and finished products while maintaining a temperature in the freezer space. The team’s comprehensive engineering drawings satisfied stringent safety design standards for the facility and enabled maximum racking and pallet positions.

CoolSys Management team successfully conducted the equipment RFP for the client, overseeing procurement, delivery and installation of the transcritical CO2 systems, adiabatic gas coolers and advanced control systems. Despite facing delays from other trades, the team adeptly rearranged non-essential construction tasks, ensuring the project’s timely completion.

CoolSys Energy Solutions installed and tested the controls and set the alarm parameters to ensure that the overall refrigeration system’s energy consumption could be initially and continuously optimized, while safety systems and alarming could continue to be supervised, as required.

Furthermore, CoolSys managed the refrigeration system startup, overseeing the commissioning and warranty processes.

CED’s design incorporated a CO2 refrigeration system—a natural refrigerant solution that satisfies the customer’s operational requirements and environmental goals. System specifications included:

The Impact:

CoolSys provided a one-stop source for a broad array of services the pet food manufacturer required to complete its design-build project, executing all tasks within the agreed-upon time and budget. CoolSys’ team of expertly trained CO2 technicians continues to provide preventative maintenance and repair for the systems to guarantee peak performance, easing the workload of the customer’s in-house technicians.

The pet food manufacturer, impressed by CoolSys’ work, is now considering utilizing CoolSys’ comprehensive solutions to upgrade its manufacturing facilities across the U.S.
