How Much Does a Double Membrane Gas Holder Cost?

For customers involved in biogas projects, wastewater treatment, or biomass energy projects, the first question they usually ask when they learn about double membrane gas holders is:

“How much does a gas holder cost?”

However, they often discover an interesting phenomenon — for the same storage capacity, quotations from different manufacturers may vary by 30% or even 50%.

Some suppliers quote RMB 80,000, some quote RMB 150,000, and others quote RMB 200,000 or more. Customers become confused:

1.Which price is actually reasonable?

A double membrane gas holder is not a standard product with a fixed price, like buying a household appliance. It is a customized gas storage system, and its price is determined by multiple factors, including capacity, material, configuration, installation conditions, and project requirements.

Without understanding these factors, simply comparing prices can easily lead to the wrong choice.

This article will help you understand:

How to choose the most cost-effective solution?

What is the approximate price range of double membrane gas holders?

What factors influence the quotation?

2. How Much Does a Double Membrane Gas Holder Usually Cost?

First, let’s provide a general market reference range to help you understand the approximate cost.

Important note: The prices above are estimated ranges. The actual quotation must be determined according to specific project requirements.

Why is there such a large price difference?

Because the price is determined by far more than just the storage capacity.

Let’s analyze the key factors one by one.

3. Main Factors Affecting the Price of Double Membrane Gas Holders

• Capacity and Size — The Most Basic but Critical Factor

The larger the gas holder volume, the more membrane material is required, and the higher the cost will be.

However, one point is often overlooked:

Even with the same volume, different length-to-diameter ratios can result in different membrane consumption.

For example, if the installation site limits the height, the gas holder may need to be designed as a shorter and wider structure. In this case, the required membrane area may actually increase, resulting in higher costs.

• Membrane Material — The “Core” of the Gas Holder

The most important component of a double membrane gas holder is the PVDF-coated fabric membrane used for the outer and inner membranes.

Imported Membrane vs. High-quality Domestic Membrane:

• Imported membrane materials can have a service life of 20–25 years.
• High-quality domestic membrane materials generally have a service life of 10–15 years.

Imported membrane materials may cost 30%–60% more, but they can provide better long-term value due to their longer service life.

Membrane Weight and Thickness:

Higher-pressure applications require thicker and stronger membrane materials, which naturally increase the cost.

Different working pressure requirements require different membrane specifications.

UV Resistance and Corrosion Resistance:

The outer membrane is exposed to outdoor environments. Its resistance to ultraviolet aging directly affects the service life of the gas holder.

High-quality membranes use special UV-resistant coatings, which increase the initial cost but provide better durability.

• Auxiliary Equipment Configuration — A “Basic Gas Holder” and a “Complete System” Are Different

A complete double membrane gas holder system includes much more than just the membrane structure.

It may include:

• Explosion-proof blower (to maintain positive pressure inside the gas holder)
• Biogas compressor (when gas boosting is required)
• Flame arrestor and safety valve (for safety protection)
• Pressure, liquid level, and temperature monitoring systems
• Intelligent PLC automatic control system
• Gas inlet/outlet pipelines and flange connections

For the same capacity, different configurations can result in a price difference of more than 100%.

When requesting quotations, customers should carefully check whether these components are included.

• Installation and Site Conditions — Hidden Costs That Are Easily Ignored

Foundation Construction:

• Is a concrete foundation ring wall required?
• What are the local soil conditions?

Transportation Distance:

• Membrane materials are large in volume, and transportation costs increase for remote areas.

Installation Difficulty:

• Are lifting facilities available on site?
• Are there additional risks from working at height?

Weather Conditions:

• Membrane welding and installation require suitable weather conditions.
• Severe weather may extend the construction period.

Many customers focus only on the equipment price but ignore these “implementation costs.”

• Customization Level — Non-standard Requirements Increase Design and Manufacturing Costs

Customized requirements may include:

• Special dimension designs due to site limitations
• Special pipeline interface requirements
• Explosion-proof requirements for chemical or gas applications
• Specific industry certifications (such as CE, ISO, special equipment certifications)

• After-sales Service and Warranty — Buying a Product Also Means Buying Security

Important factors include:

Warranty Period:

• 1 year?
• 3 years?
• 5 years?

Service Coverage:

• Are regular inspections included?
• What is the response time after equipment failure?
• Is membrane replacement service provided at preferential prices?

A lower price often means limited service.

However, the production losses caused by gas holder failure can be much higher than the money saved initially.

4. Why You Should Not Compare Double Membrane Gas Holders Only by Price

Choosing a supplier only based on the lowest price is one of the most common mistakes in the industry.

• Low-price Trap:

Some manufacturers offer a very low basic gas holder price.

After signing the contract, additional costs appear one by one:

• Foundation construction charged separately
• Blower charged separately
• Installation charged separately
• Transportation charged separately

In the end, the total cost may not be lower than other suppliers.

• Missing Items in Quotations:

Some quotations intentionally exclude auxiliary equipment or installation costs.

The price looks attractive at first, but customers discover missing items after the project starts and have to pay extra.

• Poor-quality Membrane Materials:

The membrane is the most critical component of a double membrane gas holder.

Gas holders made with low-quality membrane materials may start aging, leaking, or deteriorating within only a few years.

The cost of replacing the membrane can be almost equal to purchasing a new gas holder.

Therefore:

Choosing a gas holder is not about choosing the cheapest one, but choosing the most suitable one.

5. How to Choose the Most Cost-effective Double Membrane Gas Holder?

Cost-effectiveness does not mean the lowest price.

It means obtaining the most reliable product and service within your budget.

Follow these steps:

• Confirm Your Project Requirements

• Gas holder volume
• Available installation space (length, width, height limitations)
• Working pressure requirements
• Gas type (biogas, landfill gas, natural gas, etc.)
• Required auxiliary equipment (blower, compressor, control system)
• Installation location and transportation conditions

• Request Complete Quotations from 3–5 Manufacturers

The quotation should clearly include:

• Membrane brand, model, and thickness
• Complete auxiliary equipment list
• Installation cost
• Transportation cost
• Taxes
• Warranty period
• After-sales service terms

• 3. Evaluate Manufacturer Strength

Check:

• Does the company have similar project experience?
• Does it have its own membrane processing and manufacturing line?
• Does it have professional installation teams?
• What is the customer feedback?

• 4. Make a Comprehensive Evaluation

Do not focus only on price.

Compare:

• Price
• Configuration
• Warranty
• Project experience

Calculate the full life-cycle cost:

Initial investment + maintenance cost × service life

7. Conclusion

There is no fixed answer to the price of a double membrane gas holder.

However, after reading this article, you should understand that:

The price is not determined by a single factor.

It is the combined result of:

• Capacity
• Membrane material
• Equipment configuration
• Installation conditions
• After-sales service

When selecting a gas holder, the key is not:

“Who is cheaper?”

but:

“Who is more reliable?”

A transparent quotation, complete configuration plan, and manufacturer with real project experience are far more valuable than an attractive but unrealistic low price.
