Plate Heat Exchanger Cleaning Methods

Above is a tranter 06t2 before and after our cleaning procedures.

Plate heat exchanger cleaning methods. Clean in place cip on site maintenance. Scalzo is the most effective product for cleaning heat exchangers although some require special products. Cleaning methods of gasket plate heat exchanger 15 jan 2019 in the drug industry process of using the gasket plate heat exchanger the calcium magnesium and carbonate in the water will be decomposed into calcium carbonate and calcium hydroxide precipitates on the heating surface of the heat exchanger forming a hard scale. Make sure you protect your eyes from splash back when cleaning with any type of acid.

Plate heat exchanger maintenance is provided through two distinct methods. Wire brushes or metal pads are discouraged because they may score the plates. Next manually apply the cleaning agent to each plate to loosen any debris that may have accumulated. Wear protective goggles and gloves to protect your hands.

Cleaning methods for plate heat exchanger scaling mechanical cleaning is the simplest cleaning method but it has disadvantages like scratching the plate and causing more scaling poor working conditions for worker large workload and damaging the plates and strips because the heat exchanger must be dismantled during cleaning. The basic difference between these two methods is not how but where and who performs the maintenance. Heat exchanger plate cleaning. Scalzo contains hydrochloric acid for the most effective cleaning plus corrosion inhibitors and dispersants to ensure the metal is protected and post cleaning fouling does not occur.

Some chemicals that can be used are nitric acid citric acid or phosphoric acid. This facilitates the transfer of heat and greatly increases the speed of the temperature change. The third method which offers an alternative to external cleaning is chemical cleaning of the plates while installed in the exchanger. Wcr service invented the cleaning process that s mimicked by other heat exchanger companies even oems.

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids this has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates. The descaler is typically an inhibited acid that would be matched to the deposit composition prior to the job. Acid cleaning is only recommended if you have a lot of trouble getting the debris out of the plate heat exchanger. Authorized cleaning facilities off site maintenance.

Chemical cleaning involves circulating a specialized descaler through the cooling water side of the plate and frame exchanger. Method one is the only procedure requiring the plates to be removed from the exchanger and cleaned either on site or offsite.
