We have B1, B2 and B3 series, which are heat exchangers made up of copper tubes with aluminum fins. The aluminum fins and copper tubes employ double-flange and mechanical expand tubes techniques respectively.The fin and tube spacing are designed reasonable, which make the product compact, light and high efficient.
    B1 series: beehive type fin , φ9.52 red copper tube, fin spacing 1.4-6.3mm adjustable, optional rows(1-12rows), nice appearance, low air resistance, high heat transfer efficient.
    B2 series: adopt sine wave type and flat type, φ12.7 red copper tube, fin spacing 1.8-6.3mm adjustable, optional rows(2-12 rows), nice appearance, high heat transfer efficient.
    B3 series: sine wave type fin, φ15.88 red copper tube, fin spacing 2.8-6.35mm adjustable, rows 2,4,6,8, applicable for fresh air unit and air-conditioning process unit, preventing the breakage of the tube in winter by discharging the inside water when coil-cooling stops.

    This series is widely used in refrigeration, air-conditioning and heat ventilation such as air-conditioner, cooling, heating and dehumidify.
    B1 series is perfect auxiliary product of fan coil unit and other kinds of air-conditioners.
    B2, B3 series is perfect auxiliary product of fresh air unit and air treatment unit.
