New! Evaporator Integrity: Evaluating Tubes Using Eddy Current Testing

Caloris Engineering has made available a new white paper, Evaporator Integrity: Evaluating Tubes Using Eddy Current Testing — A Case Study.

Caloris uses eddy current testing (ECT) results to pinpoint problem areas in the tubes of existing evaporators. Targeted fixes can then be applied, potentially saving operators expensive replacement costs. This case study examines how two different customers used ECTs to determine how to invest in evaporation equipment.

Interested plant staff can request to download the white paper here, call Caloris at 410-822-6900 or send email to to speak with an engineer about evaluating evaporator health.

Sample eddy current testing report

“The eddy current tests can see parts of the evaporator that you would never be able to lay eyes on. It’s like asking ‘Will my transmission last another 20 years?’ It would be impossible to tell by looking at it. But the eddy current testing can reveal the answer.” – Jeff Podesto, Caloris West Coast Business Development Manager

ECT assesses the mechanical integrity of the tubes inside of an evaporator’s calandrias (shell and tube heat exchangers) after they have been cleaned of product deposits. The ECT provides an analysis of metal integrity down the length of each tube, reaching places that are difficult to visually inspect.
