1. The whole life cycle cost of self-purchased air compressor (high hidden cost)
The expenditure of the self-purchase model is **"large investment in the early stage + long-term continuous investment"**, including 6 major items:
Equipment procurement costs: screw machines/centrifuges, gas storage tanks, cold dryers, filters and other equipment costs, a set of small and medium-sized enterprises usually ranges from 100,000 to 500,000 yuan (according to production capacity).
Installation infrastructure costs: computer room renovation, pipeline laying, power expansion, shock absorption and noise reduction, etc., accounting for about 15%-30% of the equipment purchase price.
Electricity Cost: Air compressors are the "electric tigers," accounting for 70%-80% of their lifecycle costs. Taking a 22kW screw machine as an example, the annual operation is 8,000 hours, and the electricity cost is about 110,000 yuan/year (industrial electricity price is 1.0 yuan/kWh).
O&M Maintenance Cost:
Consumables replacement: air filter, oil filter, oil core, lubricating oil, an average of 5000-20000 yuan per year;
Labor cost: requires special inspection, operation, or outsourcing maintenance, with an average annual cost of 3,000-10,000 yuan;
Overhaul cost: The main engine needs to be overhauled for 3-5 years of operation, and the cost is 20,000-80,000 yuan.
Depreciation cost: The equipment has a service life of about 8-10 years, with an average annual depreciation rate of 10%-12.5%.
Hidden loss costs: energy efficiency decreases due to equipment aging (5%-10% increase in annual electricity bills), pressure fluctuations lead to increased defective rates, production losses due to downtime, etc.
For example, a 22kW self-purchased air compressor costs about 1.4 million to 1.8 million yuan in the 10-year life cycle.
2. The cost of the "gas" payment model (transparent and controllable expenditure)
The core of paying by "gas" is "no upfront investment + paying according to actual gas consumption", and the expenditure only includes 2 items:
Gas fee: billed in cubic meters (Nm³), the price is negotiated according to the industry, gas consumption, and region, usually between 0.15-0.3 yuan / Nm³;
Minimal additional costs: only the maintenance of the end pipeline in the plant area is covered, and no other costs are required.
The operator bears all costs such as equipment procurement, installation, operation and maintenance, electricity bills, depreciation, etc., and customers do not need to pay for "idle capacity" (such as waste of electricity costs for idling equipment during the off-season).
For example, under the same working conditions, the gas production efficiency of a 22kW air compressor is about 2.8 Nm³/min, and the annual gas production capacity of 8,000 hours is about 1.344 million Nm³, and the gas cost for 10 years is about 2.688 million yuan based on the gas price of 0.2 yuan/Nm³? The key difference here seems to be higher, but the key difference lies in the "energy efficiency advantage": the shared air compressor uses high-efficiency permanent magnet frequency conversion dual-stage compression equipment + intelligent joint control system, which is 15%-40% higher than traditional self-purchased equipment, and the actual gas price can be lowered through energy-saving space. If the energy efficiency of the operator's equipment is 30% higher than that of the customer's old equipment, the gas bill can be reduced to less than 1.88 million yuan in 10 years; If the customer is using old, inefficient equipment, the savings will be even greater.
3. The core conclusion of long-term savings
For small and medium-sized users / new factories: savings of up to 20%-40%
There is no need to bear hundreds of thousands of equipment investment in the early stage to alleviate cash flow pressure;
Avoid hidden costs such as operation and maintenance, depreciation, and downtime, and save a total of 300,000 to 1 million yuan (according to production capacity) in 10 years.
For large energy users / high-energy consumption factories: savings of up to 15%-30%
The large-scale operation and maintenance of shared air compressor stations + intelligent energy-saving regulation is 10%-20% higher than that of single-plant self-operation and maintenance.
No need for special management, save labor costs, and save 1 million to 5 million yuan (annual gas consumption) in 10 years.
Special cases: Users who purchase new high-efficiency equipment: Savings of about 5%-15%

If the customer has just purchased Tier 1 energy efficiency equipment, the space savings of paying for "gas" mainly come from the worry-free cost of operation and maintenance outsourcing, not the electricity bill.
