FAQ

  • How does Brazed Plate Heat Exchanger work?

    A:  Kaori's Brazed Plate Heat Exchangers are made by brazing chevron stainless steel plates together and forming separate counter-current flow channels between the plates. Every other plate is reversed so the ridges of the herringbone pattern intersect with one another on adjacent plates thus forming a lattice at contact points. The lattice structure causes vigorous turbulence within the channels, providing maximum heat transfer between medias.

  • What are some Brazed Plate Heat Exchanger' Applications?

    A:  Kaori Brazed Plate Heat Exchanger can be used with various fluids:

    • All type of refrigerants. (Use of Ammonia requires nickel brazed heat exchangers) 
    • Organic solvents 
    • Oil 
    • Various brine solutions (glycol mixtures , CaC12 , alcohols, etc) 
       

    Kaori Brazed Plate Heat Exchanger can be used with:

    • Heat pumps
    • Air dryer 
    • Industrial chillers; plastic machines, welding machines, hydraulic oil presses, and compressor oil cooling. 
    • Water cooler; drinking water or water processed water for various industries. 
    • Temperature holding for storage tanks. 
    • Heat recovery including heat recycling from hot steam. 
    • Indoor heating including floor heating. 
       

    Refrigerant applications, Brazed Plate Heat Exchanger function as

    • Evaporators
    • Condensers
    • Super-Heaters for gas 
    • De-super-heaters for gas 
    • Sub-Coolers for Condensates 
    • Economizers
    • Intercoolers
    • Oil Coolers
  • What are the advantages of using Kaori’s brazed plate heat exchangers as opposed to other types of heat exchangers?

    A:  When compared to traditional shell and tube and gasket type heat exchangers, Kaori Brazed Plate Heat Exchanger provides many great advantages including:

    • Higher thermal transfer
    • Higher working pressure
    • Higher thermal resistance and higher operating temperature
    • More Compact and lighter weight
    • Lower initial and operating cost for the same performance
    • High corrosion resistance
    • No leakages
    • Easy installation and easy replacement
    • High Durability
  • Which international certifications does Kaori hold for its Brazed Plate Heat Exchanger?

  • What should I be aware of when using Brazed Plate Heat Exchangers?

    A: Fluids that are explosive, extremely flammable, highly toxic, highly corrosive, hazardous or etc. cannot be used with our Brazed Plate Heat Exchanger. (I.E. nitric acid, sulfuric acid, etc.)
         

    We recommend using clean water when applied to our Brazed Plate Heat Exchangers.  When water of unknown quality is used, a filter and strainer should be placed at the water inlet of Brazed Plate Heat Exchanger to filter out the dirt or any large particles present.  In most cases, a filter mesh size of around 20 is recommended.  If unfiltered water with particle debris is allowed to flow through the heat exchanger, particle debris can impede the flow of water.  In many cases, water will freeze within the heat exchanger and compromise the unit.
         

    Chlorinated water, swimming pool water etc. are suitable for Brazed Plate Heat Exchanger but require special corrosion resistant materials.  Please inform your sales representative if you have a need for chlorinated water applications.
         

    When Brazed Plate Heat Exchanger works as a condenser, the single-phased (gas) refrigerant should enter the condenser at top left connector and the single-phased (liquid) refrigerant leave the condenser from the bottom left connector. The water should enter the condenser at bottom right and leave the condenser from top right. In water and both of the fluids are in counter flow direction.
     

    Please see Installation Guide for more information.

  • What is the warranty period for Kaori brazed plate heat exchangers?

    A:  Warranty Period is 12 months after delivery, or else, by contract with the purchaser. 
    Exceptions are:  

    1. The failure of malfunction of Brazed Plate Heat Exchanger is caused by improper or negligent usage of Brazed Plate Heat Exchanger.  
    2. Malfunctions from accidental freezing or natural disasters such as flooding and fire.  
    3. Damages cause by improper or faulty installation or if product is exposed to corrosive elements harmful to its structure.
