Rohde Brothers achieved a remarkable feat in engineering by collaborating with a full-service boutique to install a state-of-the-art $10 million snow melt system. This project not only enhanced the guest experience but also played a crucial role in protecting the integrity of the hotel’s parking structure.

The Challenge: Faced with the need to provide a safe, snow-free environment for guests, the boutique hotel sought a solution that could handle a large and varied outdoor area. This challenge called for a design that was both innovative and aggressive.

Praise from Industry Experts: Rick Nierzwicki, Managing Director at CG Schmidt, commended the project as one of the most aggressive design solutions for such a vast area. He emphasized the success of the project was largely due to Rohde’s meticulous attention to detail and commitment to a tight construction schedule.

Our Customized Solution:

1. Extensive Snow Melt System: We designed and installed a 70,000 square foot in-slab snow melt system covering the entire parking structure, including decks, drives, sidewalks, stairwells, and ramps. The system comprised 25 zones and over 22 miles of PEX tubing.
2. Advanced Equipment Installation: We furnished and installed key components like steam to hot water heat exchangers, pumps, hydronic equipment, in-slab tubing, and controls.
3. High-End Technical Components: The project included a 3-stage high-pressure steam reducing station, two steam to hot water heat exchangers, hot water pumps, an expansion tank, glycol fill system, and sophisticated snow melt controls.
4. Storm Water Drainage Enhancement: We added and modified the storm water drainage system for the parking deck to complement the snow melt system.
5. Ventilation System Upgrade: The parking structure’s ventilation equipment was replaced with new fans and controls, ensuring proper ventilation to prevent carbon monoxide buildup.

Conclusion: This innovative snow melt system stands as a testament to Rohde’s engineering prowess and dedication to client satisfaction. By ensuring a safe, snow-free environment, we enhanced the guest experience while safeguarding the hotel’s infrastructure. If your business is looking for groundbreaking solutions in heating and ventilation, Rohde Brothers is your go-to partner.

Rohde Brothers proudly played a key role in a groundbreaking project at Kohler Pottery, an AGC Build Wisconsin Award Winner. Our mission: to ingeniously recover heat from the pottery production process, a task that not only showcased our technical expertise but also significantly reduced energy costs for Kohler Company.

Project Background: Kohler Pottery’s production involves four large kilns that reach temperatures above 800°F. With a substantial need for lower-temperature heat for pottery drying and domestic hot water generation, Kohler saw an opportunity to harness this waste heat. Our challenge was to capture and repurpose the heat from both shuttle and tunnel kilns effectively.

Innovative Solution:

1. Custom Thermal Storage Tank: Utilizing 3D modeling and Finite Element Analysis (FEA), we designed a unique thermal storage tank with a 4,000-gallon capacity, capable of handling pressures up to 400 PSIG – far exceeding typical systems.
2. Pre-Piped Pump Skid: Assembled in our shop to minimize plant disruption, this skid included an Allen-Bradley PLC for pump and heat recovery system control.
3. User-Friendly Control System: A web-based Honeywell controller allows easy operation and monitoring.
4. Efficient Heat Recovery Mechanism: We installed a high-pressure hot water coil in a bypass duct for capturing kiln waste exhaust heat, complete with a damper system for optimal heat management.
5. Closed Loop Hot Water System: This system operates between 120° to 350°F, transferring thermal energy effectively.
6. Enhanced Domestic Hot Water Heating: A brazed heat exchanger boosts domestic water temperature, allowing for reduced storage volume.

Impact and Savings: This project enabled the recovery of 254,000 therms per year, saving Kohler Company $178,000 annually in natural gas costs. Thanks to funding from WI Focus on Energy, Kohler saw a payback period of just 2.5 years.

Conclusion: The Kohler Pottery Heat Recovery project stands as a testament to Rohde’s commitment to innovative, energy-saving solutions. Our expertise in engineering and dedication to sustainability helped Kohler Pottery transform waste into a valuable resource, setting a new standard in industrial heat recovery. If your facility is looking to turn waste heat into cost savings, Rohde Brothers is ready to make it happen.

Rohde Brothers recently embarked on an ambitious project with Gold-N-Plump, a leader in the poultry industry. Our mission was to engineer a solution that turns waste heat from the ammonia cooling system into a valuable resource for the plant’s sanitation needs.

The Challenge: Gold-N-Plump needed an efficient way to heat water for production and sanitation. They turned to us to design a system that could harness the excess heat generated by their ammonia refrigeration system.

Innovative Custom Solution:

1. Groundbreaking Heat Pump Design: We developed a custom-designed heat pump that is eight times larger than traditional models, setting a new standard in the industry.
2. Efficient Heat Recovery: Our system directly recovers heat from the ammonia refrigeration system, an innovative approach to energy efficiency.
3. Integrated Control Systems: We seamlessly integrated the hot water heating system controls with the ammonia refrigeration controls for optimal performance.
4. Remote Monitoring: The inclusion of remote monitoring and data collection ensures continuous, efficient operation.
5. Rapid Implementation: Our team designed, engineered, and implemented the system within just 6 months, coordinating closely with Gold-N-Plump to minimize disruption during scheduled plant shutdowns.
6. Scaled for High Demand: The system was scaled to meet the plant’s significant daily use of 1,000,000 gallons of 140°F water.
7. Record-Setting Achievement: This project boasts the largest heat pump heat recovery unit in Wisconsin.
8. Impressive Savings: The system saves Gold-N-Plump $178,000 annually in energy costs.

Conclusion: This project is a milestone for both Rohde Brothers and Gold-N-Plump, demonstrating how innovative engineering can lead to significant energy savings and operational efficiency. We’re proud to have delivered a solution that not only meets Gold-N-Plump’s needs but also sets a new standard in industrial heat recovery. If your business is looking to turn waste into wealth, Rohde Brothers is ready to make it happen.
