อ่างน้ำหมุนเวียนอุณหภูมิต่ำ ด้วยน้ำหล่อเย็น (Water Cooler/Low Temperature Stiming Reaction Bath) ยี่ห้อ Greatwall รุ่น DHJF Series Ultra (-100℃, -120℃) (SIT110)

While, our R&D department designed a new powerful single-stage compression condensing refrigeration heat exchanger. DHJF Series Ultra Low Temperature Stirring Reaction Bath was developed on the base of this technology. This internal heat exchanger is composed of outer evaporating tubes and several inner condensing tubes. Compared with the three-leveled refrigerating group, the single compressor refrigeration unit is simpler, safer, more stable and more cost-saving.
