Cleanroom HVAC Humidification Steam Boiler – Engineered for Precision
As a leading cleanroom hvac humidification steam boiler supplier, we deliver steam‑based humidification systems that meet the stringent environmental controls demanded by semiconductor fabs, pharma labs, and advanced optics facilities. Our boilers generate saturated steam on‑demand, stabilizing relative humidity between 30 % and 70 % while maintaining ISO‑14644‑1 Class 5‑7 cleanliness. Designed for modular integration, each unit can be customized for capacity, pressure, and control interfaces to fit your plant’s HVAC layout and regulatory roadmap.
How It Works – Steam‑Based Humidification Simplified
The boiler uses a closed‑loop water‑to‑steam heat exchanger powered by a high‑efficiency gas or electric burner. Water is fed from a stainless‑steel reservoir, heated to produce dry steam, and then injected into the cleanroom’s air handling unit (AHU) via a stainless‑steel spray nozzle. Precise mass flow controllers modulate steam delivery in real time, responding to humidity set‑points supplied by the building management system (BMS). Because steam contains no dissolved minerals, there is no risk of scaling or particulate contamination—critical for environments where even a single dust particle can compromise yield.
The system also includes a condensate return line that recirculates excess water back to the boiler, reducing consumption and ensuring a stable water level. Integrated safety valves, pressure sensors, and automatic shutdown logic protect both equipment and personnel, complying with IEC 61508 functional safety standards.

Industry Certifications & Safety
Our boilers are manufactured in a ISO 9001‑registered facility and undergo rigorous testing to meet CE directives for pressure equipment. The design complies with IEC 61508 functional safety standards, ensuring fault‑tolerant operation in critical cleanroom environments. Materials are selected for corrosion resistance and particle‑free performance, with 316L stainless‑steel heat exchangers that meet USP Class 3 sanitary standards, a requirement for biotech and pharmaceutical applications.
Safety features include redundant pressure relief valves, low‑water cut‑off, flame‑failure detection, and automatic shutdown on loss of power. The unit’s wiring harness is rated for Class‑1 explosion‑proof zones, making the boiler suitable for hazardous area installations where flammable vapors may be present.

FAQ
What is the minimum order quantity (MOQ) for a custom steam boiler?
Our standard MOQ is one unit, which can be fully customized to your specifications. For bulk projects, we offer volume discounts and priority production scheduling.
Can the boiler be integrated with existing BMS protocols?
Yes. The unit supports Modbus TCP, Profibus, and 4‑20 mA analog loops out of the box. Custom protocol stacks can be added on request to match your facility’s control architecture.
What is the typical lead time after order confirmation?
Standard lead time ranges from 15 to 45 days, depending on capacity, fuel type, and optional accessories. Expedited production is available for an additional surcharge.
Do you provide on‑site installation and commissioning?
Our engineering team can perform full on‑site installation, start‑up, and performance verification. Training for your maintenance staff is included in the standard service package.
