Plate Heat Exchanger
Regular maintenance is common. Your car needs to be serviced, your computer needs to be updated, and your heat exchanger needs proper maintenance. Properly cleaning your plate and frame heat exchanger is very important. One main and important reason is efficiency. In order to keep the flow rates and pressure levels at the designed unit specifications and the heat transfer as optimal as possible the plates need to be clean. Over time, the various types of fluids that are run through the heat exchanger can start to develop process build up or scaling on the plates. This scaling reduces: flow rates, heat transfer and the efficiency of the heat exchanger.
Secondly, it’s not only important to have the plates clean, but to have the plates validated free of holes or cracks. Particularly in the food and beverage industry, cross contaminating in the products can be a very serious and costly issue. Having your plates serviced regularly helps to prevent disastrous issues that can occur when product cross contamination takes place. We can provide our customers with the option of detecting pin holes and cracks after we thoroughly clean your plates from scale, we use a dye penetrant to locate and reveal any holes that may have developed over time.
Lastly, opening up and servicing your heat exchanger, gives our technicians an opportunity to visually inspect the gaskets of each plate. As with any polymers, over time they can become hard, brittle and begin to break down. When this happens, it is possible for pieces of the gasket to break apart and enter the product, thus creating issues and causing the heat exchanger to be shut down. Depending on the application, it is important to at least open and inspect the heat exchanger, frame, plates and gaskets once a year.
Has your Plate heat exchanger been professionally cleaned by HVAC HYGIENICS? We can reduce your operating costs, obtain maximum system operation and extend component life cycles!
What is a plate heat exchanger?
Commonly referred to as a PHE it’s the means of transferring heat from one medium to another.
How often a phe should be cleaned?
Manufactures recommendations are the plates need to cleaned on a regular basis. The frequency depends on several factors such as type of material and temperatures.
Common poor maintance issues
- -- Settlement of sludge, rust or dust particles
- -- Possible contaminants entering product
- -- Reduced low rates and heat transfer
- -- Buildup of scale on PHE plates
- -- Increased operating costs
- -- Clogging of mesh filters
- -- Damaged gaskets
- -- Restricted cooling
- -- High pressure drop
- -- Biological deposits
- -- Blocked plates
- -- Water leaks
Benefits of an HVAC hygienics cleaning programme:
- -- Optimum low rates and heat transfer
- -- Free of sludge, rust or dust particles
- -- System working at peak efficiency
- -- Greener on the environment
- -- Free of PHE plate scaling
- -- Optimum pressure drop
- -- Reduced operating cost
- -- Reduced repair bills
- -- Zero leakage
- -- Clean filters
PPM cleaning will detect faults within your system before any Mechanical or Electrical failure occurs.
HVAC HYGIENICS use only user friendly, non-harmful, non-corrosive, non-acidic, and non-fuming cleaning fluids allowing it to be used in any occupied areas and safely washed down drains causing no effect to the surrounding area or wild life.
Of course, performing great maintenance on a PHE means going a little deeper, but at HVAC HYGIENICS every little extra effort is always worth it.
