The Neptronic SKE4 is a high-performance resistive electric steam humidifier, engineered for precision, reliability, and easy integration into commercial and industrial HVAC applications. The SKE4 provides consistent humidity control across a wide capacity range of 6 to 300 lb/h (≈ 2.7 to 136 kg/h).
Built for modern building automation, the SKE4 offers seamless connectivity with BACnet and Modbus protocols, making it ideal for smart buildings, data centers, healthcare facilities, and laboratory environments. Its intuitive LCD interface, modular tank design, and tool-free maintenance simplify installation and service, reducing downtime and total cost of ownership.
The SKE4 combines advanced control algorithms with durable construction, ensuring stable performance under varying load conditions. Whether used for direct room humidification or duct-mounted applications, the Neptronic SKE4 delivers clean, dependable steam and long-term operational efficiency.
Unlike electrode-based units, the SKE4 uses a permanent stainless-steel evaporation chamber, so you don’t pay every year for replacement plastic bottles.
The evaporation chamber slides out via rails; you don’t have to disconnect heating elements or steam hoses.
Detects foam and drains only as needed, conserving water and energy.
Uses two independent sensor technologies for reliable, self-calibrating readings.
Optional connectivity for building automation and IoT integration, enabling remote diagnostics and control.
Program steam cycles, drain timing, and setpoints conveniently through the interface or network.
