In industrial settings where precise temperature control is mission-critical — from chemical plants to automotive assembly lines — outdated duct heaters can become a liability. At Sinoheater, we engineer industrial duct heaters that withstand extreme conditions while delivering unmatched efficiency, safety, and longevity.

Why Industrial Operations Demand Heavy-Duty Duct Heaters

Industrial HVAC and process heating systems face unique challenges:

• Harsh Environments: Exposure to corrosive fumes, high humidity, or explosive dust.
• Continuous Operation: 24/7 runtime with zero tolerance for downtime.
• Precision Requirements: Tight temperature tolerances for processes like paint curing or material drying.

Traditional heaters often fail under these stresses, leading to:
⚠️ Costly production halts from overheating or component failures.
⚠️ Safety incidents due to inadequate spark or corrosion resistance.
⚠️ Skyrocketing energy bills from inefficient heat transfer.

Introducing the EHA Series: Engineered for Industrial Excellence

Our EHA Industrial Duct Heater redefines reliability for sectors like air, metal processing, and pharmaceuticals. Here’s how it solves industry-specific pain points:

1. Built to Endure Extreme Conditions

• 316L stainless steel housing resists corrosion from acidic fumes (ideal for wastewater treatment or chemical plants).
• Class I Div 1 Certification: Explosion-proof design for hazardous environments like grain mills or refineries.
• IP66-rated components withstand dust, moisture, and temperatures up to 1200°F (650°C).

2. Precision Meets Power

• Multi-zone heating control ensures ±0.5°F accuracy for sensitive processes (e.g., pharmaceutical drying).
• High-velocity airflow compatibility (up to 5,000 CFM) without heat stratification.
• SCR (Silicon Controlled Rectifier) power controllers enable seamless integration with PLCs for automated workflows.

3. Energy Savings You Can Measure

• Interlaced finned tubular elements boost heat transfer efficiency by 45% vs. standard coils.
• Demand-based modulation reduces idle energy waste by aligning output with real-time process needs.ey Industries We Serve
