SONDEX® SondBlock plate heat exchangers

SONDEX® SondBlock heat exchangers are compact and durable solutions for challenging applications that involve aggressive media, extreme temperatures, and/or high pressure. As SondBlock heat exchangers have no exposed gaskets, they can replace shell and tube heat exchangers and cover the same duties, yet offer numerous advantages in terms of cost, size, and performance.

SondBlock heat exchangers are much less prone to fouling and clogging and only require occasional inspection and cleaning.

Maintenance and cleaning is less time consuming and space demanding as all the panels on the heat exchanger can easily be removed. The entire plate pack is accessible from all sides with no additional space required.

Block heat exchangers in general mark the beginning of a new era of efficient heat transfer, even for the most challenging applications

Features and benefits

  • Perfect as condensers that can be configured to handle duties with or without condensate sub-cooling. SondBlock heat exchangers are also good choices as steam heaters or reboilers for non-cyclic duties, and a smooth and stable steam control system.
  • A very durable heat exchanger that excels at handling aggressive and fouling media. Able to handle aggressive media on both sides, it is a perfect solution for crude oil refineries and petrochemical plants. A top choice for the most challenging duties.
  • Increased production output due to the extended uptime of the heat exchanger. Very low maintenance and service requirements. Removable side panels provide fast and easy access to the plate pack for inspection or cleaning.
