Central Heating & Municipal Water Supply Intelligent Control System

Energy-saving heating & water supply automation with customized HV/LV cabinet, HV VFD & soft starter, PLC intelligent regulation to stabilize supply and slash power cost.

The problem we need to solve

Fixed-speed circulating pump runs at full load all year round leading to huge power waste, indoor temperature unstable caused by unregulated hot water flow, scattered community heat station hard to manage uniformly, frequent motor startup damaging equipment lifespan.

How Our System Solve Problems Step by Step?

1.Hierarchical Power Distribution Allocation

Main heating boiler high-voltage power access via KYN28A-12 cabinet; heat exchange station internal equipment uses GGD fixed cabinet for fixed loads, MNS/GCS drawer cabinet for multi-group circulating pump centralized control; reactive compensation cabinet eliminates reactive loss from frequent pump startup and stop.

2.Motor energy-saving drive matching

Big high-pressure circulating pump adopts high voltage soft starter cabinet to reduce startup impact on boiler pipeline and grid; secondary network circulating pump uses HV VFD cabinet, automatically adjusting pump speed according to outdoor ambient temperature and user-side real-time heat demand.

3.PLC intelligent closed-loop control + optional DCS cluster management

PLC collects outdoor temperature, pipeline inlet/outlet temperature, pipe network pressure and user terminal flow data to form closed-loop automatic regulation system; when outdoor temperature drops, the system automatically increases pump rotating speed to improve hot water circulation, reducing insufficient heating complaints; DCS is selected for multiple community centralized heating parks to realize remote unified management of all heat stations.

4.Remote cloud management access

System data upload cloud platform, property and municipal managers remotely view running status, modify operation parameters and receive equipment fault notification anytime.

Application & Benefits

Application: District heating station, residential community water supply station, commercial complex heating & domestic water supply system.

Benefits: Reduce 25%~40% circulating pump power consumption, stable indoor heating & domestic water pressure, cut daily maintenance manpower, realize digital centralized management.

VFD control cabinet vs soft starter cabinet: what’s the difference and which do I need?

Both reduce motor starting impact, but they have completely different working principles, functions and application scenarios. Working principle difference Soft starter: Adopts thyristor phase-controlled voltage regulation technology. It gradually increases the output voltage during startup until the motor reaches rated speed, then switches to bypass contactor for direct grid operation.

When should I choose a prefabricated box-type substation instead of a traditional civil substation?

The choice mainly depends on construction schedule, land cost, capacity demand and project nature. Box-type substations have obvious advantages in most terminal distribution and temporary power supply scenarios. Construction schedule difference Box-type substation: Fully prefabricated, wired and tested in the factory. On-site work only includes foundation construction, hoisting, cabling and
