Cross-Flow Heat Exchanger
Plate Block Heat Exchangers
Instantaneous Indirect Water Heaters
AIC PlateBlock heat exchangers are a compact and durable solution to challenging applications that involve aggressive media, extreme temperatures, and high pressures. Fully welded plate packs with no exposed gaskets, they offer numerous cost, size, and performance advantages.

Maintenance and cleaning is less time consuming and space demanding as all the panels on the heat exchanger can easily be removed on site.

Features and Benefits
- Corrugated plate pattern creates a turbulent flow that diminishes the risk of fouling and clogging on both sides . Perfect solution for crude oil refineries and petrochemical plants.
- Compact operating space due to plate pack design, which provides even flow distribution and optimized surface utilization.
- High heat recovery due to close temperature approach and ability to handle crossover temperatures.
- Flexible construction allows for different multipass configurations on each circuit, enabling big disparity in both media’s flow rates without compromising pressure drops.
- Adaptable process design engineered for vertical or horizontal mount. Operates in co-current or counter-current flow mode, for single and two-phase duties.
- Robust structure provides reliable performance in harsh high temperature and high pressure conditions.
