Is the initial cost of a resistive humidifier higher?

No. The initial purchase and installation cost between an equivalent-capacity Neptronic SKE4 and an electrode humidifier are similar. Thanks to the built-in disconnect switch, installation costs are often lower.

We have hard mains water. How often is maintenance needed with a resistive system?

Cleaning frequency depends on water hardness and daily operating hours; with hard water the steam tank needs cleaning more often. In facilities fed by RO systems, tank cleaning becomes very infrequent. With the Neptronic SKE4, this is done without tools and quickly.

Can we use deionized (DI) or reverse osmosis water?

Yes, it is the ideal choice for resistive humidifiers. No scale forms in DI or RO water; maintenance needs practically drop to zero. For electrode systems, DI/RO water is completely prohibited, they cannot conduct electricity in these waters and will not operate.

Are electrode humidifier cylinders really single-use?

In most common models, yes. Electrode cylinders are made from single-use plastic material. When scale covers the electrode, the cylinder is removed and discarded, and a new one is installed. This is not only costly but also produces significant plastic waste.

Which technology should I choose for a hospital or pharmaceutical facility?

In these facilities, stable control within a narrow relative humidity band, the use of pure water (RO/DI) and hygiene come first; these requirements favour resistive technology. According to Neptronic data, resistive systems operate with ±1% RH precision and electrode systems with ±5% RH.

How is Neptronic service and spare parts availability in Türkiye?

As NKT – Nem Kontrol Teknolojileri, we are Neptronic's official distributor in Türkiye. We provide equipment supply, technical support in equipment selection, technical service and spare parts.
