Scope: Known as the fastest track in the world, LA Roser assisted with installation and continued service to this world-class ice rink.
Louis A. Roser Company prolonged the life of this world record holding facility by replacing aging shell-and-tube heat exchangers. To ensure the long-term integrity of the rink’s piping, the cooling brine was flushed and replaced with new monitoring and chemical treatment capabilities. To reduce electrical costs, a new compressor with variable frequency drive (VFD) was installed. A full flow balance of the Calcium Chloride Brine was performed.
Those entrusted with maintaining the “fastest ice on earth” rely on Louis A. Roser company to continue to service their equipment on a regular basis.
Salt Lake City, Utah
Year Completed: 2019
Scope: The Engineering team at Louis A. Roser Company was asked to evaluate the equipment at Maverik center and offer suggestions to run more efficiently and prolong the life of the facility, both with and without the ice floor in place.
Our design was approved,and weworked with Lewis Young Robertson and Lux Energy toremove some of the aging equipment and install:
A new Ammonia Compressor with a Variable Frequency Drive (VFD)
New Evaporative Condenser and Cooling Towers
Ammonia to Brine HX for the ice floor
New Brine Pumps and associated piping
Ammonia to Glycol HX for arena comfort cooling
The retrofit went well, it works wonderfully, and looks amazing. Best of all, the soft ice issues are resolved, and they have reduced electrical costs.
Eccles Ice Center
Year Completed: 2018
Scope: The Louis A. Roser Company prolonged the life of this amazing facility by replacing the aged shell-and-tube heat exchanger. We also installed a new condenser and brine pump. The photos highlight the craftsmanship of our insulation team. We enjoy working with the Eccles Ice Center and are proud supports of their annual “Spice on Ice” event.
Year Completed: 2011
Scope: Geneva Nitrogen is a unique facility in that it uses ammonia refrigeration systems to chill ammonia. They can store millions of pounds of ammonia at any given time. In 2011, LA Roser 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%.

Scope: Linde Gas has utilized LA Roser for many aspects of their system, including service work and controls upgrades. In 2012, the facility in Lima, Ohio upgraded the compressor controls from a manual, analog system to a more current, user-friendly digital control system. This greatly enhanced the compressors, allowing them to all communicate together, and ensure the system is not over-working.

This greatly enhanced the compressor performance, allowing the controls and compressor to work together efficiently.
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.

These new chillers only take up a small fraction of the space for the same capacity.
Potato Products of 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.

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 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
Danone purchased an old dairy processing facility in Salt Lake City, Utah. Due to the change to an Ultra-Pasteurized process of theorganic 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!
