These specs make the SWEP E8ASH a go-to choice for applications requiring <\/span>high-efficiency brazed plate heat exchangers<\/span><\/span>, such as air conditioning units, heat pumps, and solar thermal systems. Its vacuum-brazed construction ensures leak-proof joints at every contact point, with no gaskets to degrade over time.<\/span><\/span><\/span>Performance Data and Hydraulic\/Thermal Characteristics<\/span><\/span><\/span>SWEP’s AsyMatrix design in the E8ASH optimizes flow dynamics: refrigerant channels promote high turbulence for superior heat transfer (up to 5,000 W\/m\u00b2K), while water channels reduce pressure drop to under 20 kPa at typical flows. This asymmetry prevents the common trade-off in symmetric BPHEs, where boosting heat transfer spikes energy use for pumping.<\/span><\/span><\/span>Typical Performance Example<\/span><\/span> (for water-to-refrigerant evaporation at 5\u00b0C evaporation temperature, 40\/45\u00b0C water inlet\/outlet):<\/span><\/span><\/span><\/p>\n

    \n
  • Thermal Capacity<\/span><\/span>: 20\u201350 kW (scalable with plate count: 10\u2013200 plates)<\/span><\/span><\/li>\n
  • Refrigerant Flow Rate<\/span><\/span>: 0.5\u20132 kg\/s (R410A, R134a, CO2, or ammonia compatible)<\/span><\/span><\/li>\n
  • Water Flow Rate<\/span><\/span>: 1\u20133 m\u00b3\/h<\/span><\/span><\/li>\n
  • Pressure Drop (Water Side)<\/span><\/span>: 10\u201315 kPa<\/span><\/span><\/li>\n
  • Pressure Drop (Refrigerant Side)<\/span><\/span>: 50\u2013100 kPa<\/span><\/span><\/li>\n
  • Approach Temperature<\/span><\/span>: As low as 2\u20133\u00b0C for energy recovery<\/span><\/span><\/li>\n<\/ul>\n

    For precise sizing, use SWEP’s online selection tool or consult the official datasheet. In district energy setups, the E8ASH can handle several megawatts when paralleled, supporting sustainable goals like net-zero emissions.<\/span><\/span><\/span>Installation and Maintenance Guidelines<\/span><\/span><\/span>Installing a <\/span>SWEP E8ASH BPHE<\/span><\/span> is straightforward, enhancing its appeal for field technicians:<\/span><\/span><\/span><\/p>\n

      \n
    1. Orientation<\/span><\/span>: Mount vertically (ports up) for optimal drainage in refrigeration; horizontal for heating.<\/span><\/span><\/li>\n
    2. Connections<\/span><\/span>: Use silver solder (min. 45% Ag) at 450\u2013800\u00b0C\u2014never direct flame at the unit. Protect with a wet rag to avoid overheating.<\/span><\/span><\/li>\n
    3. Flow Direction<\/span><\/span>: Counter-current recommended for max efficiency; label ports clearly (hot\/cold inlets).<\/span><\/span><\/li>\n
    4. Cleaning<\/span><\/span>: CIP-compatible; flush with water or mild acid for scale buildup. No routine maintenance needed due to robust brazed design.<\/span><\/span><\/li>\n
    5. Safety Notes<\/span><\/span>: For flammable refrigerants, use welded fittings only. Ensure system pressure stays below 10 bar for potable water apps.<\/span><\/span><\/li>\n<\/ol>\n
