Construction

Construction

- Compact Design - Maximum Efficiency - Small Water Content

Counter-Flow Principle

- Optimum Heat Transfer - Minimum Soot - Controlled Gas Flow

Staggered Tube Configuration

- Minimum fire risk - Easy to Clean - Low Surface Temperature - Low Exhaust Gas Temperature - Free Expansion - Dry Running up to 450°C - Exhaust Gas Temperature - Short Delivery Time (in stock) - Approved Construction - Ease of Transport & Installation

Plain Tubes

Spirally Wound Tubes

Standard Sections

- No Water Level Inside Boiler - Choice of Direction of gas and water

Forced Circulation

- Easy to Use - Highest efficiency - Minimum Maintenance
