Double Helix Manure Heat Exchangers



Double helix heat exchangers are specifically designed for thermal processing of manure, sludge and any other liquid biomass. With the double helix system, cold substrate can be circulated against heated substrate for heat recovery purposes. This makes our double helix heat exchanger system optimal for economical hygienisation and pasteurisation, heat recovery and for external heating systems for biogas digesters with estremely low energy loss.
