Envirex® tube-in-tube heat exchangers are designed for applications where a facility already has a hot water source or is using a separate hot water boiler. The proven grooved piping system provides efficient heating or cooling of sludge with large return elbows to prevent clogging. A modular design allows for flexibility and expansion in meeting changing requirements over time.
