Claro designs & manufactures proprietary large-gap heat exchangers that deliver maximum heating & cooling transfer efficiencies for sludge-to-sludge applications. Consistently-sized & large throughput diameters prevent clogging even with poorly screened sludges & other process liquids. Quick & direct access to all heat exchanger internals—doors open on both sides of the unit. Standard & custom heating & cooling capacities with very compact footprints.

Applications include a wide variety of municipal & industrial uses including: sludge heating, heat/energy recovery from a variety of sources, the heating & cooling requirements of biosolids renewable fuel processes, pulp & paper, food processing, & other uses.

Recover up to 85% of outgoing heat energy from process tanks such as anaerobic digesters with Claro heat exchangers. Immediate energy cost-savings & very quick pay-back periods. Please see Claro Heat & Energy Recovery.
