When it comes to curing prints in screen printing and digital printing, choosing the right dryer is essential to efficiency, consistency, and overall production quality. The two most common types of conveyor tunnel dryers are gas and electric, and each has its own advantages and drawbacks. Understanding the differences will help you determine which is best suited for your operation.
Gas Dryers - For Large Production
Advantages:
-
Gentler Heat - Gas dryers offer a gentler heat that is better for your t-shirts, especially 50/50s, tri-blends and other sensitive garments.
-
Lower Operating Costs – Natural gas is typically more affordable than electricity, resulting in lower long-term costs. (https://lawsonsp.com/blogs/education-and-training/understand-screen-printing-and-direct-to-garment-dtg-dryer-energy-costs-comparing-gas-vs-electric-dryers)
-
Even Heat Distribution – Gas dryers use convection to generate heat, which involves the movement and manipulation of air molecules to transfer warmth.
-
Better for Large Runs – Due to their efficiency and lower operating costs, gas dryers are best for shops handling large-scale production.
Disadvantages:
-
Higher Initial Cost – Gas dryers tend to have a higher upfront investment compared to electric models.
-
Ventilation Requirements – Proper ventilation is necessary to expel fumes, which may require additional infrastructure.
-
Space Considerations – Gas dryers are usually larger, requiring more floor space.
Best For:
-
High-volume shops: Ideal for businesses that print large volumes.
-
Speciality Printing: If you print on sensitive garments or a lot of poly or tri-blends.
-
Water-Based & Digital Inks: Due to the convection design, gas dryers excel at curing water-based and digital/DTG inks.
-
Shops with proper ventilation: If you already have or can install a proper venting system, a gas dryer could be the more cost-effective choice.
Electric Dryers - For Smaller Print Runs
Advantages:
-
Faster Heating – Electric dryers reach curing temperatures quickly, making them ideal for when you want to start up and go.
-
Lower Initial Cost – Electric dryers are more affordable upfront, making them a good choice for small shops or startups.
-
Easy Installation – Unlike gas dryers, electric models don’t require specialized ventilation systems.
-
Compact and Portable – Many electric dryers have a smaller footprint, making them suitable for limited spaces.
Disadvantages:
-
Higher Energy Costs – Electricity typically costs more than natural gas in many areas, leading to higher operating expenses over time. (https://lawsonsp.com/blogs/education-and-training/understand-screen-printing-and-direct-to-garment-dtg-dryer-energy-costs-comparing-gas-vs-electric-dryers)
-
Power Consumption - Large electric dryers may require more power (amperage) or a phase (1-Phase vs 3-Phase) that may not be available at your location.
Best For:
-
Smaller shops or startups: If you’re just starting out, an electric dryer offers an affordable and accessible option.
-
Shops without ventilation systems: Electric dryers don’t require venting, making them ideal for locations without gas infrastructure.
Final Verdict: Which Dryer is Best for You?
The right choice depends on your production volume, ink type, available space, and budget. If you’re running a high-production shop, consider a gas dryer for speed and efficiency. However, if you’re a smaller operation or working in a small space, an electric dryer is likely your best bet.
