One, Product Performance 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; all emissions meet environmental protection standards. Utilizes a new double-drum three-pass structure to increase feedwater temperature, stabilize steam pressure, achieve high energy conversion rates over 93%, and produce steam in 2-3 minutes with exhaust temperatures of 50-60℃ (can use plastic or PVC pipes for the chimney). The preheater features a serpentine fin pattern to enhance thermal efficiency; it changes the original ambient temperature feedwater to 95-100℃ feedwater (or use this hot water for other purposes), reducing energy consumption. Larger storage space for steam, providing better steam pressure stability and meeting steam demand. Dual level gauges and storage spaces for steam, ensuring more stable steam pressure and meeting steam usage. 3. Easy Operation: Fully automatic with a computerized LCD touch screen control, automatic pressure adjustment, automatic water refilling, automatic heating mode switching, high level of automation, and one-touch operation. 4. Safety Features: Over-pressure and water failure protection, triple protection with dual valves and pressure controllers, reliable. 5. Environmental Friendly: Non-polluting, clean and hygienic, a new generation of energy-saving and environmentally friendly product. 6. Wide Application: Suitable for school, hotel, and corporate cafeteria steam cooking; also ideal for heating, chemical processing, garment processing, and laundry ironing processes.
