Waste Heat Recovery - Geothermal Pond Loop

Pond Geothermal Heat Exchanger

Using 3D modeling and FEA, Rohde has designed and installed various geothermal pond loop systems to provide heating and cooling.  Our innovative approach allows us to capture waste process heat to reduce maintenance and operating costs associated with steam generators, high pressure hot water systems, and cooling towers.

The Rohde Customized Solution:
  • Patent pending undersized pond system to eliminate need for expensive vertical wells
  • Combine process cooling loops with geothermal loop to allow beneficial reuse of waste process heat from air compressors, refrigeration compressors and hydraulic systems
  • Waste heat utilized with heat pumps for comfort heating, sanitation, and process heating
  • Geothermal loop provides cooling for excess heat minimizing the need for cooling towers
  • Skid-mounted pump systems pre-piped and pre-wired with controls to reduce cost and time of installation
  • Web-based Honeywell Tridium control system to provide graphical user interface over the Allen-Bradley PLC system
