Manual Graphite Plate and Frame Heat Exchanger, Color : Black

Graphite Plate & Frame heat exchangers are designed to cool down or heat up ultra-corrosive chemicals. Safety, reliability, and performance in the long-term are our primary considerations when we size, design and manufacture our impervious graphite plate heat exchangers. 

Key benefits:

Efficiency

2 to 3 times higher efficiency:

These units deliver 2–3 times greater efficiency compared to conventional heat exchangers, allowing for a much more compact design. The high internal turbulence significantly increases the film heat transfer coefficient, resulting in superior thermal performance.

Corrosion Resistance

Exceptional resistance to aggressive acids:

Our range of impervious graphite plate heat exchangers offers highly customized solutions for ultra-corrosive heat transfer applications. They provide excellent corrosion resistance to strong acids including HCl, HF, H₂SO₄, and HBr.

However, they exhibit limited resistance to oxidizing agents such as Cl₂ and high-concentration H₂SO₄ (above 65%), as well as caustic solutions like KOH and NaOH.

Modular Design

Ultra-compact and fully customizable:

Every impervious graphite plate heat exchanger is designed with a modular architecture, enabling precise adaptation to specific process requirements.

The number and dimensions of plates, along with process and service-side flow passes, can be customized to achieve optimal velocities, pressure drops, and heat transfer efficiency.

All graphite plates are precision-machined after impregnation, ensuring a perfectly smooth heat transfer surface and delivering excellent corrosion resistance along with long-term operational reliability.
