SKR Residential Steam Humidifier

Efficient resistive steam humidification for
homes, condos & light commercial spaces

Overview

The Neptronic SKR Residential Steam Humidifier is a resistive electric steam humidifier designed for precise humidity control in residential, multi-unit residential, and light commercial HVAC systems. Utilizing an immersed heating element within a durable stainless-steel evaporation chamber, the SKR generates sterile, mineral-free steam independent of water conductivity, eliminating the need for disposable electrode cylinders and reducing long-term operating costs.

Engineered for integration into forced-air duct systems or remote Steam Distribution Units (SDUs), the SKR offers both On/Off and modulating control options to accommodate varying load profiles and tighter humidity tolerances. Its compact footprint and simplified electrical and plumbing connections streamline installation, while the serviceable boiling chamber and self-cleaning heating elements minimize scaling impact and extend equipment lifespan.

Advantages

Clean, Sterile Steam

Generates mineral-free, odorless humidification for healthier indoor air.

Permanent Stainless-Steel Chamber

Easy to clean and built for durability.

Low Installation Cost

Simple wiring and setup for residential use.

Quiet Operation

Designed to blend into living spaces with minimal noise.

Flexible Installation

Works with remote SDUs or through-wall setups for non-ducted environments.

SDU (Remote Space Distribution Unit)

The SDU is a compact remote outlet that lets steam from the SKR humidifier be delivered directly into a room rather than through a duct system. It installs through a wall partition and uses a flexible steam hose, operating at low noise levels suitable for living spaces. This makes the system quieter and more adaptable where ductwork isn’t available.
