勝川熱工 List of Products and Services

Katsukawa Thermal Engineering is a specialized manufacturer of finned tube heat exchangers for process air conditioning, primarily focusing on the Erofin and plate fin types necessary for industrial process air conditioning. Since our founding in 1934, we have been committed to "technology," "speed," and "trouble-solving capabilities," while also focusing on the development of engineers. We have delivered numerous heat exchangers to a wide range of industries, including automotive, pharmaceuticals, semiconductors, and food manufacturers. We take pride in our design and technical capabilities, which set us apart from other companies. We provide high-quality products based on reliable technology with short lead times and low costs. 【Wide Range of Heat Exchangers Supported】 - Heaters and coolers used in dryers, coolers, and dehumidifiers for heating and cooling industrial products - Unit heaters for heating - Hot and cold water coils within air conditioning units - Radiators for agriculture and horticulture, and radiators for snow melting in cold regions, among others For more details, please contact us or download our catalog.

Plate fin tubes are fin tubes that can combine pipes and fins made from various materials. The key to plate fins is pitch accuracy, and thanks to our self-developed high-performance servo motors, we can achieve a high precision of less than 3mm error over an effective length of 3000mm, proudly reproducing the design capacity faithfully compared to other hydraulic systems. 【Features】 ○ High-precision plate fin elements ○ Fin pitch error is less than 3mm over an effective length of 3000mm ○ Independently developed plate fin manufacturing machine ○ Fin pitch controlled in 0.1mm increments using NC control For more details, please contact us or download the catalog.

LS fin tubes are automatically and perfectly bonded with L-shaped fins on the outer circumference of the pipe using our unique special machine, allowing us to achieve heat transfer efficiency comparable to that of integral structures like rolled fins. The LS fins developed by Katsukawa Thermal Engineering Co., Ltd. are wrapped in a spiral using a special crimping method, resulting in a larger contact area and superior adhesion compared to conventional elofin tubes, thus achieving high thermal conductivity. 【Features】 ○ Exhibits higher performance than elofin tube types under certain conditions ○ When used in circulation-type drying ovens (dryers), it can fit into approximately half the heat transfer area compared to elofin types at maximum For more details, please contact us or download the catalog.

Welding fin tubes are continuously welded to the tube with fins spirally wrapped around it using high-frequency resistance welding. In the case of the Erofin tube, the welding of the fins and pipe occurs only at both ends. 【Features】 [Welding Fin Tube Flange Type] ○ Excellent durability and thermal conductivity, allowing for semi-permanent use ○ No reduction in capacity due to damage For more details, please contact us or download the catalog.

At Katsukawa Thermal Engineering, we also supply steam piping along with heat exchangers. We offer vertical tube heaters (with horizontal airflow) and horizontal tube heaters (with vertical airflow). Our sales engineers conduct piping diagnostics, so we provide on-site assessments for users who experience issues such as damage after repeatedly replacing heat exchangers. 【Features】 [Steam Heater and Steam Piping Construction] ○ We handle the design and construction of steam piping for steam heaters. ○ We have extensive experience with steam equipment that complies with domestic regulations and international standards. For more details, please contact us or download the catalog.

The Erofin tube uses our unique machine to automatically wrap the outer circumference of the pipe with complete adhesion, achieving a structure that is as integral as a single piece while maintaining excellent thermal conductivity. The outer diameter, length, width, and pitch of the fins can be customized in various ways according to your requirements. Additionally, the pipe and fins can be combined using stainless steel, iron, and copper for the wrapping process. It is widely used in heating and drying equipment for natural convection and forced ventilation. 【Features】 ◎ Superior fin adhesion rate, fin pitch accuracy, and impact resistance compared to conventional products ◎ In addition to standard specifications, we can also produce pipes with diameters, fin heights, and fin pitches close to specifications ◎ Effective lengths of up to 6.0m can be produced, with quantities starting from one piece ★ We are currently offering "product introduction materials" and "documents containing basic knowledge about heat exchangers"! For more details, please check the PDF download. Feel free to contact us with any inquiries.

The "LS Fin Tube" features fins shaped like an L that wrap around the outer circumference of a pipe, increasing the contact area with the pipe to improve thermal conductivity. When adopted in hot air circulation dryers, it demonstrates equivalent drying performance even when the heat transfer area is significantly reduced to about half that of our conventional Erofin heater. (Note 1) It contributes to total cost reduction by lowering heater prices, weight, and fan static pressure. We offer a wide range of outer pipe diameters, making it easy to replace existing Erofin tubes. ■ Achieves high heat exchange efficiency while minimizing heat transfer area ■ Enables space-saving and energy-saving equipment ■ Wide lineup of outer pipe diameters from Φ16mm to Φ76.3mm ■ Suitable for large dryers and air conditioning units, just like Erofin tubes ★ For more details, please refer to the catalog available for download as a PDF. We also provide materials introducing the basics of heat exchangers, their types, and their roles in manufacturing lines.
