HRZQ/S series heat exchanger machine set is competitive heat exchanger integrated with High efficiency heat exchanger, cycling pump, electric adjusting valve, water compensating pump Thermometer, Pressure gauge, dirt separator, different sensors, pipelines and valves. And we have added water compensating system, pressure fixing system, water treatment system, frequency conversion flow control system, calorimeters and network communication control system. So, most of the site installation and adjustment work that been done at the user's home has been moved to our wide, bright workshop. And what's more, we enjoy the most advanced technology, abundant experience, standard modul-designe the best parts of the machine, such as pumps, valves and so on which we imported from the world famous water supply equipment company. Maturely, We can make the most use of above advantages to product the excellent heat exchangers to meet your special requirements according to your unique conditions. The machine will do cold condition running before being sent to the clients. As a result, the only thing the user has to do is to get ready four or five tube line and one piece of power line linked with the power source, and then we can adjust the machine for users. Main characteristics 1. It is reasonably arranged, convenient to install and reliable in operation. It has compact conformation, superior performance but only takes a little space 2. It is provided with climate compensatory function. 3. Primary and secondary water supply sides adopt high-accuracy motorized valve and frequency-changing pump accommodation, making it energy-saving and efficient. 4. Equipment operation can be monitored on line at any moment. 5. This machine set fitly selects ISG (IRG) series of inline pump and LG series of high rise building feed pump. Its dynamo is soundly equipped as to reduce operating cost to the maximum and save expense for customers.
