Cetetube - Shell and tube heat exchanger

Product catalog summary

Overview of Cetetube Heat Exchangers
The Cetetube range of liquid/liquid heat exchangers is designed for a variety of operating conditions, with ratings up to 5 MW. They are available in three basic thermal lengths, making it easy to find an optimal solution for most applications.

Design and Construction
The Cetetube features finned copper tubes that enhance the heat transfer area and provide stability. The design ensures turbulent flow inside and outside the tubes, which is beneficial for heat exchange and reduces the risk of fouling. The shell is made of pressure vessel steel, conforming to relevant standards, and the coil is made of spiral-round, seamless copper tube with fins.

Operating Conditions
The heat exchangers are designed for the same pressures and temperatures on both sides, suitable for heating, ventilation, and hot water systems. The maximum operating pressure is 1.6 MPa on the shell side and 2.5 MPa on the tube side, with maximum temperatures of 150°C and 160°C, respectively.

Installation and Connections
The Cetetube heat exchangers come with tubular legs and adjustable feet for installation. They feature flange connections PN40 on the tube side and PN16 on the shell side. For optimal performance, the liquid with the lower flow rate should be routed through the coil, except for domestic hot water, which must flow through the coil.

Quality and Standards
All sizes are designed and rated according to the Pressure Equipment Directive (PED) and approved by German TÜV. The Cetetube is available in seven sizes, with designations ranging from 460 to 3500, and in three different thermal lengths. Non-standard units are available upon request.

Cetetube - Shell and tube heat exchanger-1

Shell and tube heat exchanger Cetetube The Cetetube range of liquid/liquid heat exchangers comprises a number of sizes, with ratings of up to around 5 MW. The Cetetube is manufactured in three different basic thermal lengths. So it is easy to find a heat exchanger that will offer optimum properties for most operating conditions. Thermally optimized A Cetetube coil consists of finned copper tubes. The finned tube is designed to provide flow areas to suit modern operating conditions in heat exchange technology. Due to the fins, the outside heat transfer area of the tube is many times larger and they also serve as distinct spacers between the tube rows to ensure stability of the coil. Due to the stability and thus the repeatability in production, every Cetetube heat exchanger maintains the specified output. The heat exchanger is designed to ensure turbulent flow both inside and outside the tubes. The turbulent flow is favourable from the heat exchange viewpoint and makes the heat exchangers self-cleaning, with little risk of fouling of the heat transfer surfaces. For a variety of operating conditions The Cetetube is designed for the same pressures and temperatures on both sides. The same heat exchanger type can be used for different operating conditions, and all of them can be used in heating, ventilation and hot water systems. In order to put the heat transfer capacity of the heat exchanger to maximum use, the higher flow rate is routed through the shell. However, for domestic hot water, the tap water flow must always be connected to the coil side.
