Product details

The high-efficiency heat exchange unit is a set of targeted automation system tailor-made for heat exchange stations by Anyin Tongrui Energy Saving Equipment., Ltd. after years of collecting and analyzing customer demands and combining the actual situation of heat exchange stations. It has all the functions such as data collection, programmable control, regulation, over-limit alarm, remote communication and remote control. Users can choose the required functions and control methods according to the actual needs. The automation unit adopts touch screen display, human-machine interface and complete functions with simple operation.

functions that the high-efficiency heat exchange unit can achieve are

The water supply temperature of the heat exchange unit is constant and automatically controlled. water supply temperature can be automatically adjusted according to the outdoor temperature, and the speed of water supply temperature rise and fall can be freely adjusted.

Water supply over temperature alarm, when the water supply temperature continues to exceed the set value within a certain range, the unmanned heat exchange unit will send alarm, prompting the manager to check whether the temperature self-control system has failed.

Water supply overpressure alarm, when the water supply pressure continues to exceed a certain range of the set value, the unmanned heat exchange unit sends an and opens the pressure relief valve at the same time to drain and relieve pressure. The pressure setting deviation of the pressure relief valve is set to prevent the pressure relief valve from repeatedly starting stopping.

The circulating pump can be set to equal pressure difference and variable flow control by time period, and the make-up water pump automatically supplies water, with the make-up water pump set to make-up water pressure deviation; all water pump motors have self-protection functions, and overvoltage, overcurrent, undervoltage, overload, phase loss, output short circuit, overheating and other protection are realized through the frequency converter; the water pump realizes fault switching, and the frequency converter automatically stops and alarms after detecting abnormalities in the water pump motor, and starts another water pump at the same time.

Backwater pressure loss alarm, when the backwater pressure of the unattended heat exchange unit is lower than the set value, alarm and automatically stop the circulating.

The circulating pump and the steam valve are interlocked. After the water pump stops running due to power failure or fault, the steam valve is closed uncond to prevent accidents.

Frequency converter fault alarm and self-cut, when the frequency converter has a fault, it will automatically alarm and switch to the working frequency.

Low efficiency alarm, automatically alarm when the thermal conversion efficiency of the unattended heat exchanger unit is reduced, prompting the manager to check and repair.

All data of the heat exchange station can be uploaded to the superior machine through the network or GPRS, remote monitoring and remote control can be realized.
