シーテック List of Products and Services

Our company handles "plate-type heat exchangers (gas-gas)" which are formed by shaping and welding two metal plates into one set, and then combining several sets into a unified structure. These metal plates serve as elements that utilize exhaust gases and other gases to heat air or other gases through convective heat transfer. Moreover, when both fluids being exchanged are gases, the design can be made significantly more compact compared to multi-tube types, allowing for weight reduction and making it an economically advantageous heat exchanger. 【Features】 ■ Since the elements are combinations of flat plates, it is possible to keep pressure loss low. ■ In harsh environments such as waste incineration plants and industrial waste treatment facilities, dust adhesion is minimal, and by optionally installing dust removal devices, clogging in the element flow paths can be resolved. ■ If the elements are damaged due to corrosion or other factors, it is possible to replace them one block at a time. *For more details, please download the PDF or feel free to contact us.

Our company handles "fin tube type heat exchangers," which are equipped with thin plates called fins, measuring 0.2mm to 0.3mm, pressed and installed using a dedicated press machine. The pitch of the fins is approximately 2mm to 3mm, allowing for a larger heat transfer area in a small space. Additionally, this product is recommended for combinations such as liquid-gas, where there is a significant difference in the individual boundary layer heat transfer coefficients. Conversely, it is not suitable for heat exchange between "liquids" or "gases" of the same type. 【Product Lineup】 ■ Plate fin tube type heat exchangers ■ Erofin tubes *For more details, please download the PDF or feel free to contact us.

• Heat exchanger

Our company offers a "compact multi-tube heat exchanger" that prevents scale adhesion through self-cleaning action due to high flow rates within the tubes, achieving a long lifespan. By using stainless steel or titanium thin tubes, even at low flow rates, the flow velocity inside the tubes increases, resulting in a higher film heat transfer coefficient and enabling a compact design. Additionally, the structure directly welds the tube sheet to the shell (TEMA-N type), allowing for installation in the middle of piping. 【The following thin tubes are used for the heat transfer tubes】 ■S6: Outer diameter φ6.0mm, wall thickness 0.5mm or 1.0mm ■S8: Outer diameter φ8.0mm, wall thickness 0.5mm or 1.0mm ■S10: Outer diameter φ10.0mm, wall thickness 1.0mm ■SU *U-tube type: φ8.0mm, wall thickness 0.5mm *For more details, please download the PDF or feel free to contact us.

• Heat exchanger

Our company handles "multi-tube heat exchangers (shell & tube type heat exchangers)" that can accommodate fluids such as liquids and gases, ranging from high temperatures to low temperatures, as well as from low pressure to high pressure. These exchangers are applicable not only for heating and cooling but also for condensation and evaporation. We not only replace existing equipment but also calculate the thermal balance and necessary heat transfer area (U-value) from data sheets, and design new equipment. Furthermore, even if there are uncertainties or inconsistencies in the information on the data sheets, we will engage in discussions with our customers as needed, providing a one-stop service from design and manufacturing to aftercare after delivery. 【Product Lineup】 ■ Fixed tube sheet type TEMA: BEM ■ U-tube type TEMA: BEU ■ Floating head type TEMA: AES *For more details, please download the PDF or feel free to contact us.
