LDR Series Small Scale Hot Water Boilers, Features and Advantages: 1. Low Management Costs: Not classified as special equipment, no need for boiler operation permits or operator qualifications. 2. Energy-Saving: Innovative structure, compact size, high thermal efficiency, fully compliant with environmental protection standards. Utilizes a new double drum three-pass design to increase feedwater temperature, stabilize steam pressure, and achieve an energy conversion rate of over 93%. Steam is produced in 2-3 minutes, with flue gas temperatures of 50-60℃ (can use plastic or PVC pipes for the chimney); the preheater uses a serpentine fin pattern to enhance thermal efficiency. It raises the incoming water temperature from ambient to 95-100℃, reducing energy consumption. Larger steam storage space ensures better steam pressure stability and meets steam demand. Dual water level gauges and dual steam storage spaces for enhanced pressure stability and steam usage. 3. Easy Operation: Fully automatic with a computerized LCD touch screen control, automatic pressure regulation, automatic water replenishment, and automatic heating mode switching. High degree of automation with a single-button operation. 4. Safety Features: Overpressure and water cut-off protection, triple protection with dual valves and pressure controllers for reliability. 5. Environmental Friendly: Non-polluting, clean and hygienic, representing the new generation of energy-saving and environmentally friendly products. 6. Wide Application: Suitable for school, hotel, and corporate canteen steaming; also ideal for heating, chemical processing, garment processing, and laundry ironing processes.
