Technical Features and Advantages

---

① High Flow & Extreme Thermal Efficiency

Featuring a generous channel volume of 0.74 L per channel, the CB400 accommodates high volume flows up to 200 m³/h while maintaining remarkably low pressure drops. The optimized plate corrugation triggers high fluid turbulence, achieving superior heat transfer even at low flow velocities.

---

② Compact Footprint & Cost-Effective Integration

Compared to traditional shell-and-tube heat exchangers of equivalent capacity, the CB400 reduces required installation space by up to 80%. This compact, lightweight design drastically cuts down structural installation costs and simplifies piping layouts.

---

③ Robust Copper Brazed Construction

By eliminating the need for rubber gaskets and thick frame plates, the 100% copper-brazed structure ensures a completely sealed, leak-proof performance. It safely operates under high-temperature ranges from -196°C to +225°C and pressures up to 30 bar.
