01 · Context
Steel, plastics, food, airports — these sites consume enormous energy, and a large share of their heat is vented straight out of production and wasted.
Steam, gas and electricity keep getting more expensive. Saving energy is no longer an environmental slogan; it is an operating problem.
For an energy-intensive plant, saving energy is not optional. It is a question of profit and competitiveness.
02 · The problem
Low-grade waste heat, exhaust heat and condensate heat go unused, so plants keep buying steam or fuel. Equipment runs hot and inefficient, and without monitoring data, savings are hard to quantify.
The real problem is not a lack of energy. It is that so much energy is never used a second time.
03 · Our solutions
We do not sell a single machine. We help a plant build an energy loop that keeps saving.
Identify and recover flue, steam and condensate heat
Lift low-grade heat to a usable temperature
Recovered heat goes straight back to production
System-level design for overall efficiency
Live monitoring, alerts and ongoing operation
Savings that can be measured, accounted for and reported
Equipment, engineering, data and operation — one energy loop that keeps saving.
04 · Core equipment and principle
In one sentence:Heat that was “not hot enough to use” is lifted back into hot water, steam or process heat the plant can keep using.
05 · A real process route
The Linyi Steel Investment Special Steel project. Low-grade heat in blast-furnace slag-flushing water is captured, lifted, and used for heating and cooling.
Hot slag-flushing water (90–100℃) enters the slag pool
Filters and plate heat exchangers draw the heat out
A two-stage single-effect hot-water unit (own invention patent) raises the grade
Heating at 75/59℃ and cooling at 7/12℃, with a closed cooling-tower loop
06 · How we deliver
Every site has its own process conditions, heat sources and production needs. We cover the whole path from assessment to delivery and operation.
Where recoverable heat is, its temperature band, how it is vented, and its potential
Process and operating data used to value recovery and size the savings
Recovery path designed; exchange, transport, control and auxiliaries matched
Continuous monitoring and tuning for stability and long-term savings
A saving that works starts on the plant floor and ends inside the system.
07 · Patents and credentials
Covering heat recovery, absorption heat pumps, system integration and monitoring; designed to the site and delivered to run.
Our own patents and third-party verification make “real and effective” more than a slogan.

10 · Data centres and power
Liquid-cooling return water from data centres and the cooling loops of gas engines are steady, year-round low-grade heat. We package the heat exchange, pumps, controls and heat-pump / ORC interfaces as a standard module so that the design, the quote and the delivery repeat. 25 MW is an engineering block, not a machine model: a 100 MW project is about four units.
Two heat sources, one exchange, upgrade and control platform
Liquid-cooling return 30–55 °C
A heat pump lifts it to 70–95 °C; with no heat user, heat returns to the original rejection system.
Jacket water · intercooler · aftercooler · lube oil 50–90 °C
Total heat is set by the OEM heat balance; 350–450 °C exhaust gets its own heat-recovery boiler or ORC.
Four outcome targets for a 25 MW unit
Target ranges. Each is checked against project data in FEED (front-end engineering design); electricity savings are settled on independent metering.
Worked example · 25 MW data centre, PUE 1.35 → 1.25
Excludes heat sales, extra generation, financing cost and tax. China scenario at CNY 0.65 / kWh: about CNY 13.65 M a year, payback 1.8–4.4 years.
One 25 MW heat-recovery system, six engineering boundaries
CDU or engine temperature and flow
Plate exchangers protect the host system
Pumps, valves, buffer tanks
Heat pump or ORC, chosen by use
PLC / EMS: temperature, flow, heat
Heating, hot water, cooling or power
Protect the host system first, then save energy. If the heat user stops, a heat pump fails or load swings, the system bypasses automatically and the original cooling keeps 100% of its rejection capacity. No interface crosses the OEM warranty boundary.
Pricing basis · from core package to complete energy station
Data audit, heat balance, concept and budget
Exchange, pumps, controls, core unit
Adds heat pump / ORC and module integration
Design, procurement, construction, commissioning
Engineering contract value excluding tax. US projects are quoted in USD alongside; exchange rate set on signing.

Where we stand: industrial sites have verified 41% and 50.54% saving cases; a dedicated data-centre operating reference is still being built.
Market window
11 · Grain drying
The coal-fired hot-air furnace is replaced by an air-source heat-pump hot-air system, one heat pump per dryer, with operating control built around temperature, airflow, humidity and electricity. Wheat and paddy rice alike.
Project under discussion · Taicang, Jiangsu
12 × 10 t = 120 t rated batch capacity, which is not daily throughput; real capacity depends on load, moisture removal and cycle. Scope: heat-source selection and siting, duct connection, controls, power capacity, steel frame, foundations and equipment protection.
How it dries · hot-air delivery with temperature and humidity control
An air-source heat pump draws heat from ambient air into the drying air
Fans and ducts organise the flow so hot air meets the grain fully
Vented or condensed per the site design, matched to temperature and humidity control
At the agreed final moisture, tested, then cooled, moved or stored
Control: a staged drying curve, with grain temperature, hot-air temperature and final moisture monitored. Return-air ratio and dehumidification method are fixed by the site design.
Unit data · proposal selection 5RWF160
Rated at 20 °C dry bulb / 15 °C wet bulb. 120 ÷ 30 = 4.0 is the nameplate heating COP, not year-round system efficiency.
Running-cost reference · Nantong, four units (2017)
52 t of wet paddy per batch, 16% final moisture, electricity at CNY 0.60 / kWh, dryer exhaust fans included. Recomputed from the original comparison table's energy use and unit prices.
Historical reference conditions; the original energy and moisture records were not independently verified, and cycles run about 20–24 hours by heat source. The reference units totalled 60 kW; this project is 360 kW with a different configuration, so costs do not simply scale by three.
A 12-dryer project needs its own energy and cost baseline
Record wet mass, initial and final moisture, grain type, drying time and quality per batch
Meter the heat pumps, existing fans, conveying and new auxiliaries separately
Batch electricity ÷ wet tonnes, weighted by real peak and off-peak tariffs
Only with equipment and installation quotes, batches per year, maintenance and applicable subsidies
Delivery · from site review to a loaded trial run
Batch mass, moisture targets, existing fan data, power capacity and installation space
Selection, duct and control design; steel frame, foundations and construction plan
Fixing, air path, electrical and protection functions; unit and system commissioning
Temperature, humidity, initial and final moisture, batch time, electricity and product quality recorded
Operating manual, parameter sheet, training and maintenance plan delivered. Warranty, response time and service scope as set in the project contract.

12 · Value to the plant
Burn less fuel, buy less steam, vent less heat. Energy costs fall, and the savings become auditable emission cuts.
What we save a plant is not only energy — it is long-term operating cost and an auditable emissions record.
13 · Why us
We do not stop at a proposal. Equipment, engineering, data and operation — the whole loop, closed.
14 · Belief
Industrial sites are complex, heavy and never stop. But complex does not mean beyond optimising, and loss should never be taken for granted.
Real efficiency comes from understanding the system again — seeing the heat that was ignored, tracing its path, and bringing it back into production value.
Every unit of energy deserves to be managed seriously
Every waste may hide new value
Every industrial system has room to improve
Sustainability is not a slogan but engineering that lands
Real expertise makes a complex system clear, controllable and sustainable.
15 · Contact
Industrial sites hold a great deal of ignored heat. With real equipment and engineering, we help plants use it again — lowering energy, steam and cost step by step, with data that makes the savings visible, measurable and lasting.
