HUAYUANFILTER GQ01A is a single-coil cooler, used as an I-level (pre) cooler in the system. The cooling water enters the water tangentially from the bottom, and the sample water undergoes reverse heat exchange. The coil adopts F14×3mm seamless stainless steel tube, which can withstand the high temperature difference between the sample water and the cooling water. Improve the impact resistance of the coil.

GQ02B is a dual-coil cooler, used as the second-stage cooler in the system. The cooling water enters from the bottom and flows through the two processes of the inner coil and the outer coil. The cooling water is led to the flange surface through the middle duct of the inner coil. The cooling water flows through the inner and outer coils in sequence. , The sample water and cooling water conduct reverse heat exchange during the whole process. After level I pre-cooling, the temperature of the sample water drops below 100°C. Since the temperature difference between the sample water and the cooling water is reduced, the F8×1.5 stainless steel coil is used to increase the effective cooling area, so it has an efficient cooling effect.
