Basic parameter table

The GLII type is a steel double circuit (two rows) or multi circuit (four rows) air heat exchanger. The finned tubes are made of seamless steel pipes with a diameter of 18 × 2mm wound with 10 × 0.3mm corrugated steel strips, forming a spiral shape with a spacing of 3.2mm. There are various surface tube numbers, tube lengths, and row numbers to form various 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. It can be used as an air heater or air cooler, and is an economical, durable, and versatile air heat exchanger.

GL II type numbering method

Model - number of rows - number of surface tubes - length of surface tubes (inches).

If four rows are used, with 10 surface tubes and a tube length of 42 inches, it is GL II-4-10-42.

The basic parameters of GL II type are shown in the table.
