Shell and Tube Heat Exchanger

Corrugated Tube Heat Exchanger is shell and tube heat exchangers which use corrugated tubes instead of plain tubes. Corrugated tubes take the best features of both the plain tube and the plate heat exchanger. The tubes are corrugated to induce turbulence in both flows (product service) at lower velocities. This not only increases thermal efficiency but also eliminates product channeling. Thermal efficiency is so improved, that for typical thin film applications heat transfer area can be reduced to less than half of that required in a plain tubular heat exchanger.

Models available:

• K-Series
• DT-Series
• MI-Series
• AS-Series Heat Exchanger

Features:

• ‘K’ Series heat exchanger consists of a bundle of tubes within a common shell
• MI– Series is multi-tube heat exchanger for heat recovery and food applications.
• DT- Series is a tube in the tube heat exchanger is capable of handling large particulates.
• AS-Series heat exchangers are made from three concentric tubes, which give three annular spaces. The product fluid channel is surrounded on both sides by the service fluid. It is widely used for Aseptic and Heat Sensitive Material.

Application:

• The heat exchanger finds its extensive use in various industries such as Chemical process, Pharmaceutical (bulk drugs and formulations), Petrochemicals, Fertilizers, Edible oil Industries, Paper Pulp, Power, steel, coal, oil refinery, food and beverage processing industry and many more where a shell and tube heat exchanger is used. The heat exchanger can be used as Condenser, cooler, chillier, heater, sub-cooler, heat recovery applications and many more applications.

The heart of a Plate Heat Exchanger is a pack of embossed plates with apertures. The plates are assembled in a 180° angle to each other, resulting in flow gaps on each side. Each plate is provided with a gasket, which securely seals the flow gaps from the atmosphere and separates the two media used in the heat exchange. The gasket plate pack is mounted in a rack and is compressed with tightening bolts between the fixed plate and the movable plate. To guarantee maximum heat transfer, warm and cold media are normally fed through the PHE in one-pass or multi-pass counterflow. Connections are on the fixed plate, but can also be on the movable plate for multipass flow.

Advantages:

• Low investment, operation, and maintenance costs.
• Highly efficient heat transfer (K- values on average 3-5 times higher than in the case of bare-tube heat exchangers).
• Asymmetrical flow gap is available for the most cost-effective solution.
• Use of smallest temperature difference
• Up to 75% less space required.
• The self-cleaning effect due to highly turbulent flow behavior
• Future additional capacity is possible by fitting extra heat transfer plates
• Double gasket with leak groove gives high safety with regards to media mixing.
• Easy to open/clean
• Low operating weight/low liquid content.
