BLACK CONTINUOUSLY PLATED SOLCHROME SOLAR SELECTIVELY COATED TIG/ULTRASONIC WELDED FIN AND TUBE

• Welded in a continuous process.
• No use of solder, adhesive as in mechanical joints.
• The metallurgical bonding ensures:
  (i) A very high degree of thermal efficiency.
  (ii) Ability to withstand upto 200 to 300 degrees centigrade stagnation temperature.
• Continuous welding ensures better efficiency due to unrestricted transfer of heat from Fin to the Tube.
• Extremely high durability due to metallurgical bonding.
• 100% quality assurance through rigid tests including hydraulic pressure testing.
