    *Channel Form Characteristics

    L channel: low heat transfer coefficient, low resistance, suitable for large flow rate and weak heat transfer (low specific heat or small temperature difference), such as air heat transfer under ambient pressure.

    H channel: high heat transfer coefficient, high resistance, suitable for small flow rate and strong heat transfer (high specific heat, with phase change or large temperature difference), such as refrigerant phase change heat transfer.

    M channel: heat transfer coefficient and resistance are between H channel and L channel.

    Tips: Counter flow brazed plate heat exchanger troubleshooting.

    Malfunction Cause Solution
    Liquid crossing
    1. Operating conditions did not meet design requirements of the plate heat exchanger.
    2. The residual stress after cold stamping of the plate and clamping size in assembly are too small, causing stress corrosion.
    3. Leakage groove of the heat exchanger plate has a slight leakage, which causes the harmful substances in the medium to condense, corrode the plate, and cause liquid crossing.
    1. Adjust operating specifications of the plate heat exchanger to meet designed conditions.
    2. Clamping dimensions of the heat exchanger during maintenance and assembly should meet requirements, and not as small as possible.
    External leakage
    1. Improper clamping dimensions, uneven dimensions everywhere, or loose clamping bolts.
    2. Part of the gasket is detached from sealing groove, main sealing surface of the gasket is contaminated, gasket is  damaged or the gasket is aging.
    3. Plate is deformed, and displacement occurs during assembly, causing the gasket to run.
    4. There are cracks in plate sealing groove or in the second sealing area
    1. Under pressure-free conditions, re-clamp the device to clamping dimensions provided by plate heat exchanger manufacturer. Pressing size deviation and the parallelism between two pressing plates should be kept within 2mm.
    2. Mark the leaks, then disassemble the plate heat exchanger, and troubleshoot them one by one. When no spare parts are available, temporarily remove the deformed plate and reassemble it for use.
    Excessive pressure drop
    1. Pipeline of the operating system was not properly purged, and many dirt entered the inside of the plate heat exchanger. Flow channel cross-sectional area of the plate heat exchanger is narrow. Sediment and suspended matter in the heat exchanger are collected at corner hole and backflow area, which results in area of the flow channel there is greatly reduced. Therefore, the pressure is mainly lost in this part.
    2. After the plate heat exchanger is operated for a period of time, the pressure drop is too large due to fouling on plate surface.
    1. Remove dirt or scale from the plate heat exchanger flow channel. For newly running system, clean it once a week
      according to actual situation.
    2. The secondary circulating water is preferably soft water after being softened.

    Amazingly well
    I'm using this to transfer heat from my domestic hot water heater to radiant floor loop. No leaks, strong, well built heat exchanger. Transfers heat amazingly well.

    Awesome heat exchanger
    I mainly use heat exchanger if I need a hydronic zone off a gas steam boiler, only a few companies have tankless coils on gas boilers, so this is a good option.

    Good 300 plate heat exchanger, good price.
    Installed two of these, one for my domestic hot water and another for my sister. Both of us have the same outdoor wood stove. Installed just like manufacture recommends and they work great!

    Well worth the money
    I put this heat exchanger on my car to use as an engine oil cooler and it is working great so far. I am running the oil through one side of this heat exchanger and coolant through the other side. So far so good, the oil temp is staying within a couple of degrees of coolant temp and there are no leaks, so I am very pleased.

    Well built
    Using this heat exchanger as a boiler essentially. Heats slab much faster than thermal transfer fluid always circulating. Excellent product!! I really like this product. I will recommend it to my friends.

    Perfect heat exchanger custom service.
    Before purchase, I communicated with seller and got professional answers and suggestions. Because specifications is customized, its performance met my requirements. I used the heat exchanger to modify gearbox oil cooling device, heat dissipation effect is very good, no leakage.
