Precision-Engineered for
Peak Thermal Performance
At Thermal Engineering International (TEi), we design and manufacture custom feedwater heaters to meet exacting thermal demands—whether it’s extreme superheat, abnormal flow conditions, or the controlled dissipation of high-energy fluids. With over 100 years of engineering expertise, TEi feedwater heaters are built for performance, reliability, and long service life.
From design through installation, testing, and full or part-load operation, TEi solutions help power plants maximize cycle efficiency and minimize operational disruptions.
Compact. Efficient. Purpose-Built.
TEi has designed and manufactured over 2500 low pressure feedwater heaters with all types of tube materials and configurations. Our Vertical Channel Down (VCD) designs reduce footprint and streamline piping layouts, while offering easier bundle access and simplified maintenance. Each LP heater is custom-built to meet specific site conditions and thermal demands.
Advanced Design for Demanding Conditions
High pressure feedwater heaters operate in extreme environments—often above 1000 psi—and require proven engineering solutions. TEi delivers with sophisticated designs that handle severe superheat, complex flow paths, and high-energy fluid dissipation. We specialize in optimizing performance under both normal and overload conditions through robust mechanical designs and advanced thermal modeling.
Custom Desuperheater & Drain Cooler Zones: Engineered for optimal drying and flash performance
Efficient Venting Systems: Enhances heater operation and steam quality
Vibration Analysis: Comprehensive modeling ensures durability under both normal and overload conditions
Channel Closure Options:
- Bolted-Gasketed – Cost-effective, easy to disassemble
- Seal-Welded Diaphragm – Leak-proof, no gaskets required
