GL_IIThe U-shaped radiator is a steel double circuit (two rows) or multi circuit (four rows) radiatorair-to-air heat exchangerThe finned tube is made by winding a seamless steel pipe with a diameter of 18 × 2mm and a steel strip with a diameter of 10 × 0.3mm, forming a spiral shape. It can be composed of various surface tube numbers, tube lengths, and row numbers to form multiple specifications. The inlet and outlet pipes are located on the same side, with steam or high-temperature water as the working heat source and low-temperature water or saltwater as the cold source. They can be used as air heaters or air coolers and are economical, durable, and versatileradiator.
GL_IIThe type numbering method is: Type number in one row - surface pipe length (inches). If four rows are used, with 10 surface pipes and a pipe length of 42 inches, it is GL_II-4-10-42.
