steam generator for coffee machines

This coffee machine uses electric steam generator made of stainless steel. It is especially designed for espresso machines, capsule coffee systems, and other devices able to rapidly generate stable hot water and high-temperature steam. Made from 304 food-grade stainless steel, it readily cleans and is resistant to corrosion. With a PID temperature control system for 3-second heating and ±1°C precise temperature control, this meets the dual requirements of steam milk frothing and espresso extraction. The totally enclosed system eliminates the hidden danger of leaking; the anti-scaling device reduces scale deposition and extends service life. A modular design helps compact models; an energy-saving mode also reduces energy consumption. Safe, reliable, and compliant with CE and RoHS certifications, it helps coffee devices’ product stability and steam performance.

1. Product Application Overview

Our ​​steam generator heating elements for coffee machines​​ are critical components in ​​electric boiler heaters​​, designed to deliver precise, rapid steam generation for espresso machines, pod coffee makers, and commercial coffee brewing systems. They convert electrical energy into controlled thermal energy to produce hot, dry steam (ideal for milk frothing, coffee warming, or flavor infusion), ensuring consistent performance in both home and commercial coffee preparation. Optimized for high efficiency and durability, these elements withstand frequent use and contact with water, making them essential for maintaining the quality and speed of coffee service.

2. Product Parameters (Aligned with Factory Capabilities)

Parameter Specification Range Options de personnalisation
Power Rating 800W–3000W (household coffee machines); 1500W–5000W (commercial espresso systems). Custom wattage (e.g., 500W–6000W).
Operating Voltage 110V/220V (standard household); 220V/380V (commercial 3-phase). Custom voltage (e.g., 12V–480V).
Material Primary: 304 stainless steel (food-grade, corrosion-resistant for water contact). Optional: 316L SS (for high-purity or hard water environments). High-nickel alloys (e.g., Incoloy 800) for extreme temps.
Dimensions Length: 100mm–800mm; Diameter: 10mm–25mm (fits compact coffee machine boilers). Tailored length/diameter to match specific machine chambers (e.g., pod coffee makers).
Temperature Resistance Continuous: 750°C–850°C; Peak: 950°C (stable under rapid heating cycles for quick steam). Ceramic insulation for >1000°C in high-demand models.
Pressure Resistance Rated ≤3 bar (standard for home coffee machines); ≤5 bar (commercial espresso). Reinforced casing for ≥7 bar in industrial coffee systems.

3. Key Advantages

  • ​Coffee-Specific Precision​​: In-house welding and stamping workshops ensure tight tolerances for stable steam output, critical for milk frothing and flavor extraction.
  • ​Corrosion & Scale Resistance​​: 304/316L SS construction and optional anti-lime-scale coatings extend lifespan in hard water or high-use environments.
  • ​Rapid Response Design​​: Optimized heating elements reduce warm-up time to <90 seconds, matching coffee machine fast-service requirements.
  • ​OEM Adaptability​​: Flexible production lines accommodate custom dimensions, power, or material needs (e.g., slim profiles for compact espresso machines).
  • ​Certified Reliability​​: 100% pre-shipment testing (leakage, insulation resistance, thermal cycling) meets CE, UL, and ISO 9001 standards for food-safe applications.
