Rasmussen became my “one stop shop” for ALL my boiler needs. All I had to do was call and explain what was going on and then sit back. Parts were ordered in a timely fashion and Techs arrived when they said they would. Work was always done quickly and second to none! Great feeling knowing I have a company that has my back and has proven it over and over for the past 21 years.

We needed (help with) mechanical projects; welding, boiler, steam, condensate, compressed air, in different areas around our plant. Rasmussen Mechanical Services helped us evaluate our options and save us a lot of time and money to get back on line – ASAP.
Matt Stryson
Plant Engineer, Hughes Brothers Inc.
I wouldn’t recommend anyone else… We had issues that other technicians couldn't get to the bottom of so Rasmussen came in and did the repair work and followed up with preventive maintenance.

We get all of our help from Rasmussen. I can call on the phone and talk with somebody and they are local.

Rasmussen Mechanical is a key partner in our school district's efforts to maintain effective and efficient mechanical systems.
Jeremy Christiansen
Superintendent, Laurel – Concord – Coleridge Schools
You were by far the best outside contracting crew we have ever had the opportunity to work with. The knowledge and expertise was superior. Your guys did an outstanding job replacing our boiler's burners.
James Rucker
Maintenance Supervisor, WireCo
Rasmussen does the job right the first time.
Steve Feauto
Maintenance Custodial Supervisor, Riverside Elementary, Oakland, IA
I’ve worked in facilities all my life, for 35 years. I would recommend Rasmussen Mechanical because of their outstanding service and reliability... If my boilers break down I know who I’m going to call and who’s going to show up.
David McAtee
Director of Operations, Boystown National Research Hospital, Omaha, NE
I would recommend them to work with other people just based on the quality and craftsmanship of their work. We went from 75%-80% efficient to 92%-94% efficient. A 12%-15% gas savings for the plant.
Conrad Baldwin
Facilities Utility Planner, Kelloggs, Omaha, NE
They’ve done a tremendous job for us. Not only are they there to do a job, but they can break it down to layman’s terms, so that as an operator, I can practice what they teach me. We’ve learned from their experience so it’s kind of a win-win for all of us.
Robert Stiles
Utility Technician, Mars Petcare, Aurora, NE
They do more than what’s expected and we have one contact we can call for many different services.
John Nikkila
Utility Technician, West Pharmaceuticals, Kearney, NE
After the first boiler, we were so pleased with their service and quality that the second one was a no brainer.

What are some important chiller maintenance considerations?

Tube Cleaning – Tubes are the primary path for heat transfer and can have a big impact on the performance.
Condenser Water Treatment – Untreated water results in higher condenser pressures and less heat transfers. It can also cause inconsistencies in water flow and temperature. Proper chemical treatments keeps the system working correctly.
Analyze and Change Compressor Oil – Analyzing oil ensures you are changing the oil frequently enough.
Purge Low Pressure Machines – This involves purging the system of non-condensable gases. This ensure air and moisture are low.
Analyzing Compressor Water Temp – When possible; increasing the temperature of water being supplied to the facility will improve efficiency.
Look at Flow Rates – Flow rates should be higher than 3 feet per second and less than 12 feet per second. To slow and you will have flow issues and two high and vibration and noise will create issues.
