BRAZED PLATE REFRIGERATION HEAT EXCHANGERS

The Brazed Plate Refrigeration Heat Exchanger  is the most efficient and compact heat exchanger for refrigeration applications. They can be supplied in single and dual circuits designs for evaporator and condenser applications.

DESIGN
The Brazed Plate Refrigeration Heat Exchanger is a variant of the traditional Gasketed Plate Heat Exchanger. It is composed to a number of ‘herringbone’ corrugated Type 316 stainless steel plates brazed together in a vacuum furnace to create a bond that allows it to operate at pressures over 600 psig. Advantages of BRAZED PLATE over other technologies

  1. Efficiency
    The brazed plate heat exchanger for refrigeration applications is the most efficient heat exchanger in the refrigeration industry. The induced turbulence through the channels formed by the herring bone corrugations allow for the liquid to flow in a forced turbulence pattern providing up to 3-5 times higher heat transfer coefficients compared with tubular heat exchangers.
  2. Compactness
    The refrigeration brazed plate heat exchanger weighs about 30% less than coaxial for a similar capacity and occupies 25% space compared to other technologies. There is a tremendous advantage over other heat exchangers for installation on skids and in restricted spaces where space is a premium.
  3. Liquid Volume
    The low hold up volume in a brazed plate heat exchanger on the refrigerant side is about 10 times lower than a tubular heat exchanger. The major advantage to this that the there is a rapid response to capacity changes and a low filling volume reducing refrigerant costs.
  4. Stock
    Valutech keeps a a large inventory of brazed plate hear exchangers for immediate delivery to replace heat exchangers that may have frozen due to valve failure or general replacements for higher capacities.
