Shell and tube heat exchanger unit heat exchanger unit 1. The lowest price and best quality high-efficiency cyclone heat exchanger unit heat exchanger, forming a vortex state in the heat transfer process, the result of this heat exchanger own self-cleaning ability , so it is not easy to furring, suspended solids and impurities in the fluid easy attachment. Tested in practical velocity (1.5-2.5 m / s) in the range, steam - water heat exchanger when the overall heat transfer coefficient: Q = 6000-7000 kcal / m2.hC, water - water heat exchanger when the overall heat transfer coefficient: Q = 4000-5000 kcal / m2.hC. Compared with tube heat exchangers, plate heat exchangers, corrugated tube heat exchangers and other heat transfer coefficient is increased 1-3 times, is a new, efficient, ideal replacement heat exchanger equipment, compared with its energy efficiency Other similar-related products increased by 15-25%. 2. Water temperature control, mechanical and electrical integration, heat capacity, without human surveillance. 3. When the condensation heating tank and fill the tank into one, small footprint, high thermal efficiency. The configuration of a liquid crystal display according to user requirements, the system displays a variety of data, including: heat medium temperature, heat medium pressure, standard room temperature, water temperature, condensation water temperature, water pressure. 5. The unit heating power, small size, small footprint, less investment. 6. The control part of the well-known manufacturers of electrical equipment, more reliable operation. 7. If the unit is used for domestic hot water, can be fixed, regular, constant pressure, constant temperature, automatic control system, automatic control, energy efficient, safe and reliable. 8. The unit is divided into Simple, standard, intelligent, configured with different prices are also different. Customers can choose different configurations, different unit price according to their own situation. Then the two sides signed the norm. Uses: This product is suitable for homes, offices, factories, hospitals, hotels, schools and other occasions, heating, bath and air conditioning system
