High-quality construction for reliable heat exchange
VEVOR 5" × 12" heat exchanger is manufactured from premium materials — 316L stainless steel with 99% copper brazing, ensuring long-lasting durability and high safety standards. The construction withstands high pressure and temperature, and UL and CE certifications guarantee reliable operation. It is ideally suited for floor heating, water heating, snow melting and beer cooling, providing safe and efficient use in both residential and commercial applications.
Efficient heat transfer with asymmetric "fishbone" pattern
The asymmetric "fishbone" pattern increases heat transfer efficiency by creating intense turbulence between media. The brazed plate heat exchanger achieves up to 99% efficiency, delivering 260–360K BTU/h output. This design maximises contact area between liquids, reducing energy and pump costs and improving overall system performance.
Large heat exchanger surface with 30 plates for optimal operation
The water-to-water heat exchanger is equipped with 30 plates (127 × 305 mm), providing a large heat exchange surface and high efficiency across various applications. Operating temperature range from –180 °C to 200 °C allows safe use in both extremely low and high temperatures. It performs excellently in floor heating, snow melting systems and other intensive processes.
Highly tight and leak-proof, ensuring longevity
The heat exchanger is brazed under vacuum at high pressure and tested with helium leak testing, completely eliminating micro-leaks. This guarantees long service life, high safety and stable operation even under prolonged load conditions. The hermetic construction ensures worry-free use and efficient operation without water loss.
Simple and stable installation with 304 stainless steel brackets
The supplied two 304 stainless steel brackets ensure secure, stable and durable installation. They are corrosion-resistant and allow quick and convenient heat exchanger installation in any environment, preventing vibration and movement during operation.
Versatile applications: floor heating, water heating, snow melting, beer cooling
The heat exchanger is highly versatile — it can be used in both residential and commercial heating and cooling. It delivers high efficiency in floor heating systems, water heating, snow melting equipment and beer cooling, adapting to various systems and providing stable performance.
Economical solution with reduced energy consumption
Thanks to high efficiency, the heat exchanger reduces pump power and electricity costs. At 260–360K BTU/h it can reduce energy consumption by up to 20%, making it a cost-effective and environmentally friendly choice. In the long term, it provides significant savings and rapid return on investment.
