Core equipment
Heat exchanger
Purac provides two kinds of heat exchangers: sludge/water heat exchanger and sludge/sludge heat exchanger. This equipment is a proprietary heat exchange product designed specifically for materials with high viscosity and solid content, and has 40 years of engineering application experience in the industry. The unique design provides a compact heat exchanger with minimal maintenance needs.
Function:
Sludge/water heat exchangers is designed based on a modular principle with circular sludge channels, which means the design can be adapted to each plant’s unique conditions. The channels provide a large throughput area that keeps pressure loss low and minimizes the risk of clogging. Each level of sludge channels is surrounded by a rectangular water circuit, in which water for heating/cooling flows in the opposite direction to the sludge.
The unique open turning chamber contributes to a compact design that is simple to install. Inspection, disassembly and maintenance are made easy because the turning chambers are mounted on a common flange. The turning chambers provide even higher heat transfer by equalizing the sludge’s temperature profile. Based on a modular principle and turning chambers, the compact design delivers low running costs.
Technical features:
• Unique design specifically for sludge
• Turning chamber
• Compact unit that is easy to install
• Simple inspection and maintenance
• High heat transfer
• Large throughput area
