Solid State Rocket Fuel

Working with a major solid-state rocket fuel producer for space exploration and NASA, we upgraded their system including replacing original upright compressors, and also shell-and-tube heat exchangers with plate and frame chiller and modern screw compressors. Using an ammonia refrigeration system to chill a brine solution, which is used in another part of their processing.

Since 2008 LA Roser has worked upgrading this system, significantly reducing the space required for equipment, and greatly improving cooling capacity.

Chilling Ammonia

A unique facility in that it uses ammonia refrigeration systems to chill ammonia. Storing millions of pounds of ammonia at any given time. Louis A. Roser Company provided a new shell-and-tube heat exchanger to chill a small part of their process. This particular chiller presented a challenge, in that the heat exchanger had to replace an existing one, and still remain on the skid package originally installed.

Louis A. Roser Company designed a refrigeration system to lower the pressure of rail car tankers reduce the offloading time. An all-stainless steel ammonia refrigeration system was integrated into their existing processes and reduced rail car unloading time by 50%.

Gas Producers

A major transformation took place when an outdated, manual analog compressor controls were replaced with a cutting-edge digital system. This upgrade brought a wave of efficiency, empowering the compressors to seamlessly communicate with each other, ensuring optimal performance without the risk of overworking the system. The result? A significant leap forward in control, reliability, and overall system performance.

Glycol Cooling Upgrades | National Dairy Producer

A prominent dairy producer recently added a new yogurt processing line, prompting the need for modifications to their existing ammonia refrigeration system to increase glycol cooling capacity. The Louis A. Roser Company played a crucial role in this upgrade, ensuring that the new system met the high standards for efficiency and reliability. Our work included the installation of compressors, condensers, a recirculator, and a plate-and-frame ammonia-to-glycol heat exchanger skid. Additionally, we assisted in the reassembly of a cooling tunnel that had been relocated from another facility.

The project began with a comprehensive 3D scan of the existing mechanical areas. Using this data, we developed detailed 3D models of the existing equipment and piping. This allowed us to seamlessly integrate all the new equipment, piping, and valves into the model. Collaborating closely with the client’s team, we reviewed the layout to ensure satisfaction with the placement of the new piping and valves. This meticulous planning enabled us to fabricate much of the piping in our shop, significantly reducing the overall cost and time required for the project.

In 2020, we made additional modifications to support a new process line that the client installed. These enhancements included the installation of hundreds of feet of new glycol piping, converting a flooded ammonia-to-glycol heat exchanger to direct injection, and removing the surge drum to reduce ammonia inventory. We also cleaned the heat exchanger plates and added new ones to increase the unit’s capacity.

Why It Matters
The expanded glycol cooling capacity was essential for the new yogurt processing line, ensuring that the client could maintain optimal production temperatures and quality.

New compressors and condensers were selected for their efficiency and reliability, providing a robust foundation for the upgraded system.

The recirculator and plate-and-frame heat exchanger skid were critical components in delivering consistent cooling performance.

Reassembling the cooling tunnel involved careful coordination and precision. The tunnel, originally from a different facility, had to be integrated seamlessly into the existing operations.

Major Refrigeration Upgrade | Spiral Freezer

To support growing demand, we had the privilege of designing and building a new ammonia refrigeration system to support two spiral freezers. This new refrigeration system is critical to maintaining the quality and consistency of truly outstanding product. By supporting the two spiral freezers, the system helps in rapidly freezing product, preserving the texture and flavor while extending shelf life.

The design and installation of this system required meticulous planning and execution. Our team worked closely with the client to understand their specific needs and operational challenges. We provided a customized solution that not only enhances their current production capabilities but also offers scalability for future growth. Integrating seamlessly with their existing infrastructure, ensured minimal disruption to their operations during the installation process.

This project is the latest in a series of successful collaborations at the same facility, demonstrating their trust in our expertise and our commitment to delivering high-quality solutions. Each system we have installed has contributed to their ability to scale up production, maintain product quality, and meet increasing market demands.

Our ongoing partnership is a testament to the value we provide our clients. We are proud to be their go-to partner for refrigeration solutions, and we look forward to continuing our support as they expand their business.

This relationship is a perfect example of why the Louis A. Roser Company has been in business since 1907. Our long history is built on delivering innovative, reliable, and efficient solutions that meet the evolving needs of our clients.

The successful implementation of this new ammonia refrigeration system not only supports the client’s current needs but also positions them for future success.

As the demand for their delicious mashed potatoes continues to grow, they know their team can rely on the Louis A. Roser Company to provide the expertise and solutions needed to stay ahead in a competitive market. This project is a proud addition to our portfolio and a shining example of our dedication to excellence in refrigeration technology.
