Three-Pass Hot Water Boiler

• Optimum heat transfer, environment friendly
• 6-8 bar operating pressure
• Up to 94,4% efficiency
• Optimum thermal balancing and heat energy use, effective heat use, three passes for reduced operation costs
• Uninterrupted passes in all three passes and balanced cooling of flue gases resulting in extended service life.
