In traditional stone processing, fire machines often struggle with limited oxygen levels in the environment, making it difficult to achieve optimal combustion efficiency. This results in prolonged processing times and excessive fuel consumption. Incomplete combustion also generates harmful exhaust gases, contributing to air pollution. If emissions exceed regulatory limits, it can lead to fines or even production shutdowns, disrupting operations significantly.

To address these pain points, Jiangsu Luoming has developed the HDFO93 Series Industrial Oxygen Generator, which uses Pressure Swing Adsorption (PSA) technology to deliver high-purity oxygen. This technology enables more efficient combustion and offers an innovative upgrade for fire machine applications.
1. Enhanced Combustion Efficiency
Insufficient oxygen often causes weak combustion in conventional systems. The HDFO93 delivers oxygen with 93% purity, offering a rich oxygen supply that fuels a hotter, more concentrated flame. Tasks like stone surface roughening or texture carving, which previously required hours, can now be completed much faster, significantly boosting output and productivity.
2. Substantial Cost Savings
With improved combustion efficiency comes a notable reduction in fuel use. Over time, switching to an oxygen-enriched system can save 30%–50% in energy costs compared to traditional methods. These savings can support equipment upgrades or business expansion. The oxygen generator itself is energy-efficient, keeping operational costs low and offering a highly favorable return on investment.
3. Improved Processing Quality
A consistent, high-temperature flame is critical for precision stonework. By providing stable oxygen output, the HDFO93 ensures steady, uniform flames, allowing for more refined surface treatments. Whether it’s slip-resistance treatment on granite or artistic engraving on marble, the results feature better flatness and clearer texture detail, setting your product quality apart from the competition.
4. Simple Operation and Maintenance
Designed with user experience in mind, the HDFO93 features a straightforward, intuitive interface. With basic training, operators can quickly get up to speed. Routine maintenance involves only periodic checks of key components, allowing for fast upkeep and minimal downtime, which keeps production running smoothly.
5. Eco-Friendly Performance
The use of high-purity oxygen supports complete fuel combustion, which significantly reduces emissions of pollutants like carbon monoxide and unburned hydrocarbons. In addition, shorter processing times reduce airborne dust, helping to improve both the workshop environment and surrounding air quality.
