Ohata laser water chiller
Laser marking is one of the most popular industrial processing methods that emerged in the late 20th century. Currently, domestic enterprises engaged in the research and development, production, and processing of laser marking machines, laser engraving machines, laser welding machines, laser inkjet printers, laser cutting machines, as well as laser processing equipment such as hospital carbon dioxide laser machines, excimer lasers, and argon ion lasers are emerging from time to time. The quality of the cooling system is a key link in the entire laser marking operation. It is precisely for this reason that the Daheda DHT series laser water chiller is designed and manufactured according to the characteristics and requirements of laser marking equipment, and is an indispensable companion in the laser industry.
Features of Ohata Laser Water Chiller Unit
The microcomputer control system can automatically control the operation of the entire machine, and is a fully functional error prevention operation system.
Electrical appliances are original products from Taian or Schneider, ensuring stable machine operation and long service life.
All titanium tubular water tank evaporator prevents the generation of solids and other metal impurities during the transportation of pure water.
The product has a wide range of specifications and varieties, suitable for matching use on different specifications of laser machines. The precise digital temperature controller can accurately control the water temperature to ± 1 ℃, and can be used normally without the need for professional personnel.
Easy to install, whether the chiller matches the laser host or not, it can be started and used normally.
Electrostatic spray plastic shell, European design, beautiful and generous.
Scope of application:
Widely used in laser marking, laser engraving, laser cutting, laser welding, laser drilling, laser marking and other laser processing equipment using YAG, carbon dioxide, and semiconductor as laser working media.
