Cooling Methods for Waterjets: Oil-Water Heat Exchange Closed Circuit and a Chiller

Waterjets, while less common than plasma or laser cutting systems—making up only 5-10% of the global market—play a vital role in cutting materials that other technologies cannot handle. Despite being significantly slower (up to 10 times slower) than thermal cutting methods, waterjets are indispensable for processing thick metals like bronze, copper, and aluminum, non-metals such as rubber and glass, organic materials like wood and ceramics, composites, and even food.

Most waterjet machines are produced by small OEMs. Regardless of size, all waterjets require effective cooling to maintain performance and longevity. The small waterjet systems typically need 2.5 to 3 kW of cooling capacity, while larger systems may require up to 8 kW or more.

An effective cooling solution for these waterjet systems is the oil-water heat exchange closed circuit combined with a water chiller. This method involves transferring heat from the waterjet's oil-based system to a separate water loop. A water chiller then removes heat from the water before it's recirculated. This closed-loop design prevents contamination and ensures optimal cooling efficiency.

TEYU S&A Chiller, a leading water chiller manufacturer, is renowned for the efficiency and stability of its chiller products. The CW series chillers offer cooling capacities from 600W to 42kW and are well-suited for cooling waterjet machines. For example, the CW-6000 chiller model provides a cooling capacity of up to 3140W, making it ideal for small waterjet systems, while the CW-6260 chiller offers up to 9000W of cooling power, perfect for larger systems. These chillers provide reliable and stable temperature control, safeguarding sensitive waterjet components from overheating. By effectively managing heat, this cooling method enhances waterjet performance and extends equipment life.

While waterjet systems may not be as widely used as their thermal cutting counterparts, their unique capabilities make them indispensable in specific industries. Effective cooling, particularly through the oil-water heat exchange closed circuit and chiller method, is critical to their performance, especially in larger, more complex systems. With TEYU high-performance water chillers, waterjet machines can operate more efficiently, ensuring long-term reliability and precision.

S&A Recirculating Water Chillers CWUL-10 for Cooling 8W UV laser

As the ambient temperature rises in hot summer, the cooling water of the water chiller is easy to deteriorate and limescale is more likely to occur, which will affect the cooling effect of the water chiller. So, how to change the circulating cooling water? Mr. Sousa from Spain, a customer of S&A water chillers, wrote and e-mail to S&A last Friday and asked the exact same question. S&A suggested to him that it is better to use clean distilled water or purified water as the circulating cooling water and change it every 15 days in the hot summer.

Mr. Sousa was quite grateful for S&A for the professional advice and prompt reply. Because of that, he placed the order again and purchased S&A recirculating water CWUL-10 to cool 8W UV laser. S&A recirculating water chiller CWUL-10 is characterized by the cooling capacity of 800W and the precise temperature control of ±0.3℃ and specially designed for cooling UV lasers. It is because the good product quality and well-established after-sales service that S&A has more and more regular customers.

In respect of production, S&A has invested the production equipment of more than one million RMB, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, all the S&A water chillers are underwritten by insurance company and the warranty period is two years.
