Premium Quality: Similar to the 30-plate model, this exchanger uses 316L stainless steel with copper-edged brazed plates, offering durability and resistance to leakage under demanding conditions.
Convenient For Use And Energy Saving: Smooth Thread connections allow for easy hookup, while the compact plate design delivers efficient heat transfer for water-to-water applications without extra energy use.
Product Parameter: Up to 250,000 BTU per hour with 20 plates, 4″ x 12″ format, and 1″ MPT ports. Suitable for a variety of heating and domestic hot water uses.
Water to Air Heat Exchanger 18×18
Excepetional Performance: This unit delivers up to 360kBtu per hour, featuring 12 aluminum fins per inch and three rows of 3/8″ seamless copper tubes. Wave fins and tube contact areas boost heat transfer efficiency for heating or cooling.
Convenient For Use And Energy Saving: Installation is simplified by slipping into the plenum with four MNPT ports. No special tools required, and the design minimizes space usage while maintaining performance.
Energy-efficient and Affordable: The exchanger supports multiple heat sources (boilers, solar panels, etc.), enabling use of renewable energy sources and reducing energy costs over time.
24×24 Heat Exchanger Water To Air
Superior Quality: A robust 24×24 steel case supports the exchanger, with 12 fins per inch and 3 rows of 3/8″ seamless copper tubes. Base brazed edges ensure durability under high pressure and temperature.
Easy Installation: Four thick MNPT ports and a plenum-ready design simplify mounting. The compact footprint saves space without compromising performance.
Highly Energy-saving: This unit directly converts thermal energy into heat transfer, leveraging highly conductive copper and aluminum to optimize efficiency, especially when paired with renewable energy sources.
14×16 Heat Exchanger Water To Air
Superior Quality: Built with a 306 steel case and 12 fins per inch, this unit uses 3 rows of 3/8″ seamless copper tubes to maximize heat transfer. Base brazed edges ensure resilience against high pressures and temperatures.
Easy To Install: Four MNPT ports enable simple insertion into the plenum, minimizing required tools and space. The compact 14×16 footprint suits tighter installations without sacrificing performance.
Energy-saving Performance: Designed to heat water directly via efficient copper/aluminum conductors, promoting energy savings and compatibility with renewable energy sources.
Buying Guide
Key considerations when selecting a water heat exchanger:
- Application type: Choose water-to-water exchangers for heating liquids, or water-to-air units for space heating or cooling. Consider the system it will integrate with (boilers, solar, wood furnaces).
- Capacity and size: Match BTU capacity to your load. Larger capacities offer more heating potential but require more space and might be overkill for small installations.
- Materials and durability: Stainless steel (316L) bodies with copper brazed edges provide strong resistance to corrosion and leakage in high-temperature environments.
- Installation ease: Look for units with plenum-friendly designs and MNPT ports that fit existing ducts or piping without excessive modification.
- Maintenance and lifespan: Brazed-plate designs tend to have fewer gaskets and leaks, offering longer service life in demanding applications.
- Energy impact: Efficient plate designs and highly conductive metals reduce heat losses, supporting energy savings when paired with renewable energy sources.
- Compatibility and upgrades: Ensure the exchanger can be integrated with existing systems ( boilers, solar collectors, pellet or wood furnaces ) and that spare parts or replacements are accessible.
When evaluating options, consider local climate, heating load, and your preferred energy mix. For homes prioritizing renewable energy integration, heat exchangers with robust copper/aluminum construction and strong corrosion resistance provide reliable performance over time. For retrofits, a compact, plenum-friendly model can simplify installation and reduce space requirements. Always verify compatibility with your specific equipment and consult a professional for complex installations.
