The compact, space saving vertical four-pass shock-proof design has no tubes to loosen or burn out. The Hurst Vertical Tubeless Boiler allows convenient access to “eye high” burner and solid-state controls for trouble free operation. Factory assembled and fully automatic. UL and ASME CSD-1 approved. Simple and inexpensive to install.

Inspection Access

  • The waterside openings are located in the most effective positions. The lower handholes offer far better access for both cleanout and inspection.
  • These more functional locations avoid the obstructing handhole “tunnels” used by our competitors.
  • The top opening offers a strategic view of the furnace crown sheet.

More Steam Storage

  • Capacity to handle swing and spike loads – quick recovery – quick response.
  • The larger steam-release surface is calmer, reducing carry over of unevaporated water.
  • The resulting drier steam also reduces system scaling.
  • In addition, dry steam helps to eliminate unnecessary extra condensate. Energy and fuel are saved. Longer life results.

Four-Pass Design

  • The gases leaving the furnace are split four ways and travel through four individual serpentine fin passages to the stack outlet.
  • Each quarter of the heat travels its own four-pass path (see illustration below).
  • Heat transfers evenly to the fins and boiler shell, eliminating the metal stress due to uneven heat transfer common in other designs.

This illustration shows the progression of four gas paths around the circumference of the boiler shell.

  1. Primary-pass in furnace pipe.
  2. Second-pass follows path through fins along outside of shell.
  3. Third-pass follows path through fins along outside of shell.
  4. Fourth-pass follows path through fins along outside of shell, then merges together to exit exhaust stack.

Options and Alternatives

  • We specialize in customizing your boiler. The Cyclone can be equipped to suit a wide variety of installations and specifications. We will help direct you to the most cost-effective models and features.

Simple Installation

  • Unit is skid mounted for easy handling.
  • Factory wired with wiring schematic included in the manual. Efficient and space saving layout.

Available Accessories

  • The Cyclone is available in a complete package with an optional compact boiler-mounted feedwater system for a finished wired and piped, ready-to-fire unit.
  • Blowdown separators are also available.

Turbulent Flame

  • Heat is forced down, with the fire whirling and spinning against its natural flow. This pattern enhances recirculation, mixing and heat transfer, driving more energy into the water for greater fuel-to-steam efficiency.

Reliability

  • The furnace crown is water cooled, eliminating troublesome refractory breakdown inherent inunits of inferior design.
  • No fire tubes, water coils or “in the fire” mud rings to burn out.

“Eye High” Burner

  • No step ladder is needed to service.
  • No bending over or sitting on the floor.
  • The air intake is located in the center of the unit so dust is not pulled from the floor.

Durability

  • Fire does not pass under the bottom mud ring, eliminating the blistering that occurs with other designs.
  • Cooler furnace gases are located at the bottom of the vessel where scale is most likely to occur. Baking of scale is alleviated.

Easier Service

  • Fireside fin access in top and bottom.
  • Access opening above feedwater inlet for easy cleaning.
  • Thoughtfully engineered with the owner in mind.
  • No heavy doors or covers to complicate service procedures.

Safety

  • Electrical components are located away from the floor, helping eliminate the possibility of water coming in contact with electricity.
  • Boiler built to ASME Section 1, High Pressure Boiler Code.CSD-1 approved.
  • Burner/Boiler UL Packaged.

                      Outside of work, Jim places a priority on his faith, family, friends, and fitness. He enjoys helping people-supporting charities, time with his wife and kids, road-biking with friends and efforts to stay physically fit.

                      A message from Jim on the achievements of SVL

                      SVL started in February 1967 by Charlie Schwab and Craig Vollhaber. Schwab-Vollhaber, Inc. (as it was named at the time) steadily grew and, in 1985, welcomed Paul Lubratt as another partner, becoming Schwab-Vollhaber-Lubratt, Inc. SVL’s founders had the determination to build the most talented, customer-focused HVAC representative in the Midwest. Our original drive and passion still shape the company and culture to this day. The achievements of an organization are the results of the combined efforts of every individual. From humble beginnings, SVL founders paved the way to industry success with hard work and determination. “Today, SVL is strongly organized with great people to lead our industry forward as we are challenged with fast-paced changes to reduce our environmental impact,” says Jim. Now, 55+ years later, SVL is under the leadership of two new principals who share the same vision and drive that has propelled SVL throughout the years. Built on a foundation of integrity, Jim Lubratt, and Charlie Vollhaber strive to ensure opportunities for personal growth, improved work environment, and shared life enrichment. The achievements of our organization are the results of the combined efforts of every individual.

                      Charlie Vollhaber

                      Executive Vice President & Officer

                      Charlie Vollhaber is a third-generation employee at SVL, as a grandson of company co-founder Craig Vollhaber and son of former CEO Todd Vollhaber. Charlie holds a Bachelor of Science in mechanical engineering and an MBA, both from the University of Minnesota. He became an outside salesman for SVL in 2013, was made a partner in 2019, and then executive vice president and officer in 2022.

                      He grew up playing sports, including football, basketball, golf, and track, and enjoys the competitive nature of the HVAC industry. “I like that no two days are ever the same as there are always questions to answer and problems to solve,” he says. “Most of all, I enjoy working with great people and coordinating together on challenging projects to achieve positive results together.”

                      Outside of work, Charlie enjoys spending time with his wife, Lesley, and their three boys. He’s also fond of golfing, traveling, and attending concerts and sporting events. One of his favorite quotes is from the book of Philippians: “Do nothing from selfish ambition or conceit, but in humility count other more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others.” Because HVAC and construction is such a team effort, he says, “this mindset helps to create positive results in a vast majority of situations.”

                      A message from Charlie on the culture of SVL

                      “At SVL, we strive to cultivate a unique culture that revolves around finding and empowering exceptional individuals. We believe in equipping our team members with the right tools and resources to succeed.

                      As we’ve grown the business, we have deliberately maintained a small firm culture, fostering an environment where collaboration thrives. We encourage open dialogue and promote a sense of comfort among our employees, allowing anyone to ask questions and seek guidance from anyone else, regardless of their level within the organization.

                      We foster a workshop-like atmosphere where everyone’s contribution is valued. Presenting your work to another individual or a group of teammates provides a platform for collaboration, where ideas are shared, dissected, and improved collectively. We firmly believe in the power of mentoring and provide various avenues for both formal and informal guidance. Whether it’s through structured training programs or casual conversations, we encourage team members to discuss a wide range of topics, from work-related successes or issues to everyday personal life topics.

                      In summary, our culture is built on the foundation of attracting exceptional individuals, empowering them with the necessary tools, and fostering a collaborative environment where mentorship and growth thrive. We are committed to creating an atmosphere where every team member feels supported, valued, and encouraged to reach their fullest potential.”

                      Al Gramse

                      Vice President of SVL Service Corporation

                      Al Gramse has been in the HVAC industry for over 30 years. He began as a service technician.  Then over his career worked in technical support, building automation, then service manager prior to his current role.

                      How did Al end up in the HVAC industry?  “After high school, I took a couple years to figure out what I wanted to do.   Where I was working at the time, a grumpy old coworker, who I didn’t get along with, walked up to me and said ‘What are you doing here?  Go back to school.’”  I said, “For what?”  He said “There’s a tech school down the street.  Go down there and pick something that interests you”. Then he walked away.  That weird interaction, with someone I didn’t get along with, sent me down a 30-year path in the HVAC industry.   Never underestimate the potential of a little encouragement.   Even if it is from a strange source.

                      Al has been with SVL for 15 years and is the head of our SVL Service division. “The people here are some of the best in the industry,” Al says. “A bunch of team-oriented, knowledgeable, go-getters.” His personal mantra is “figure it out,” “Do a little fact-finding on your own. Use your own brain before you use someone else’s. But know when to ask for help.” he prescribes. “It’s amazing what you can accomplish on your own if you dig in a little bit.”

                      Outside of work, Al has lots of outdoor hobbies, including hunting, fishing, and motorcycling, though his favorite pastime is simply hanging out with family.
