Heat Recovery for Energy Conservation

The Rohde team fully engineered the mechanical and electrical systems to recover waste heat being generated from the ammonia cooling system for use in heating water for production sanitation needs.

Customized Solution:

  • A custom designed heat pump that is 8 times larger than what is traditionally available

  • Directly recovering heat from an ammonia refrigeration system

  • Integration of hot water heating system controls with the ammonia refrigeration controls

  • Remote monitoring and data collection

  • Rohde designed, engineered and implemented the system within 6 months, typically during scheduled plant shutdowns. Working closely with Gold’n Plump’s team, Rohde ensured integration of the new system with minimal disturbance to the existing facility and processes in place

  • Rohde engineers scaled an existing heat recovery design to accommodate the plant’s daily use of 1,000,000 gallons of 140°F water for production and sanitation

  • This is the largest heat pump heat recovery unit in Wisconsin

  • Saved Gold’n Plump $178,000 per year in energy costs
