Minimum Temperature Difference of Just 2°C

The BKRV plate-shell storage type heat exchanger achieves remarkable performance in heat transfer engineering. The minimum temperature difference between the heating medium and the heated water can be as low as 2°C. This value is particularly important in heat pump systems. Smaller temperature differences can result in higher system efficiency. The heat exchange element uses a plate-shell design. Corrugated circular plates are welded together using plasma or argon arc welding. The fully welded structure provides excellent sealing and can withstand high temperatures and pressures. The design temperature range spans from -196°C to 700°C. Standard design pressures include 1.0, 1.6, 2.5, 4.0, and 6.3 MPa. This product delivers a heat transfer coefficient of 2,000 to 4,500 W/m²·°C.

Constant Hot Water Temperature with Advanced Flow Control

The tank includes water distribution devices and suction inlet devices. These components help maintain a constant hot water temperature. Multiple plate groups are welded into a column-shaped tube bundle. External baffles and flow diversion devices create multiple flow paths. Plate thickness options include 0.8, 1.0, 1.2, and 1.5 mm. The gaps between the plates provide sufficient space for fluid flow. This design helps resist fouling and scale buildup. All core components are manufactured in-house, giving us full control over quality. Compared with traditional shell-and-tube units, the plate-shell design provides a much larger heat exchange area within the same volume. The Plate-Shell Storage Type Heat Exchanger achieves higher performance with a smaller footprint.

Welding Expertise and Quality Assurance

Plate-shell construction demands precise welding. Any leakage in the welded joints could compromise performance. Our welding capabilities are a key strength. We operate plasma welding machines and tube-to-tubesheet welding equipment. Third-party inspection is welcome at any stage of production. Every unit undergoes 100% inspection before shipment. The 12-month warranty provides protection for your investment. Multiple modules can be freely combined based on your heating medium conditions. Shell material options include carbon steel lined with copper, carbon steel lined with SUS444, SUS304, or SUS316L. The plate-shell heat exchanger itself uses SUS304 or SUS316L stainless steel. This Plate-Shell Storage Type Heat Exchanger is designed for projects that require efficient heat transfer, compact construction, and reliable welded sealing.
