ATK/Thiokol

Magna, Utah

Year Completed: 2008/2009/2011

Scope: ATK is a major name in space and science, providing NASA with the solid-state rocket fuel for the space program. They use an ammonia refrigeration system to chill a brine solution, which is used in another part of their processing. In 2008 and 2009, LA Roser began upgrades to their system, including replacing the original upright compressors with the advanced screw compressors used now. In 2009 and 2011, ATK worked with LA Roser to upgrade the old, very large, shell-and-tube heat exchangers to the new, efficient plate-and-frame chillers. These only take up a small fraction of the space for the same capacity.

ATK is a major name in space and science, providing NASA with the solid-state rocket fuel for the space program. Louis A. Roser provides and services them with an ammonia refrigeration system to chill a brine solution, which is used in their processing method. Updates completed include a replacement of the original upright compressors with new, advanced screw compressors. ATK later worked with L. A. Roser to upgrade the old, very large, shell-and-tube heat exchangers to the new, efficient plate-and-frame chillers. These new chillers only take up a small fraction of the space for the same capacity.

Potato Products of Idaho

Rigby, Idaho

Year Completed: 2020

Scope: Potato Product of Idaho makes the best mashed potatoes we have ever tasted! To support the growing demand of these delicious potatoes, the Louis A. Roser Company had the privilege to design/build a new ammonia refrigeration system to support two spiral freezers.

This is not the first time that PPI has turned to L.A. Roser for our expertise. This is the third refrigeration system that we have installed at this same facility. As their business grows, they continue to turn to the Louis A. Roser Company. Just one more example of why we have been in business since 1907.

Schreiber Foods

Logan, Utah

Year Completed: 2020

Scope:In 2019 Schrieber added a new Yogurt processing line. We modified their existing ammonia refrigeration system to give them additional glycol cooling capacity. This included the installation of compressors, condensers, recirculator, and plate and frame ammonia to glycol HX skid. We also assisting in the re-assembly of cooling tunnel that was moved from a different facility.

We started by taking a 3D scan of the existing mechanical areas. We developed 3D models of the existing equipment and piping, and then we inserted all the new equipment, piping, and valves into the model. This allowed us to review the layout with the great people at Schreiber’s to ensure they were happy with the piping and valve locations. It also allowed us to fabricate much of the piping in our shop, thus reducing the overall cost of the project.

In 2020 we made additional modifications to support a new process line that was installed. This included hundreds of feet of new glycol piping, converting a flooded ammonia to glycol HX to Direct Injection, and the removal of the surge drum to reduce ammonia inventory. We also cleaned the HX plates and added new ones to increase the capacity of the unit.

Gossner Foods

Logan, Utah

Year Completed: 2020

Scope:

Gossner Foods is one of the most well-known dairies in Northern Utah & Southern Idaho with their signature ‘squeaky cheese’. We have enjoyed working with Gossner for many years. Here are a few of the projects we have had the pleasure to perform:

2019 thru 2020 – Expanded the capacity of their system by adding a new compressor, condenser, and evaporators in a new shipping cooler.

2019 we installed a new condenser and condenser control system at the Heyburn, Idaho facility.

2017 – provided a new glycol chiller package, utilizing the existing ammonia refrigeration system to improve their production capabilities.

2015 – added additional warehouse storage at their facility. L.A. Roser provided design/build services to create a state-of-the-art cheese aging/storage facility.

Danone North America

Salt Lake City, Utah

Year Completed: 2018

Scope:

Danone purchased an old dairy processing facility in Salt Lake City, Utah. Due to the change to an Ultra-Pasteurized process of the organic products, most of the facility was gutted, and new equipment was installed.

As part of this re–model Louis A. Roser Company had the privilege of working with Hill & Wilkinson out of Texas, and with Hixon Engineering out of Ohio. We all worked together to create an incredible refrigeration system for Danone. A short list of some of the major items we performed is listed below

Opened and performed UT inspection on tubes of Shell and Tube HXs
Installed new Glycol cooling system including

New piping throughout the facility
New Flooded plate and frame HX package from Evapco
New glycol storage tank and pumps

Installed new Ammonia compressors from Frick
Retrofit of existing recirculator
Added a liquid ammonia transfer pump
Installed new cooling water storage tank and pump system
Installed new fluid coolers

Installed a new ammonia diffusion tank
Installed new Evaporative Condenser
Assisted with controls changes and coordination
Provide PSM/RMP start-up assistance

We continue to support Danone on a regular basis, and we value their relationship.

This was a complex project that was performed within a very tight schedule. Well done team!

Daily’s Premium Meats

Salt Lake City, Utah

Year Completed: 2020

Scope: The Louis A. Roser Company recently installed a cooling tower for the microwave units at Daily’s Premium Meats. This installation took a load off of their existing freezer system, allowing them to both save money and free up the system’s cooling capacity for other vital loads.

In addition, our exceptional team installed both an ammonia detection and ventilation system for their plant as well. This system is running well and is controlled by Alan Bradley PLC.
