Condair RS

Resistive steam humidifier

Innovative scale management removes the separated minerals from the steam cylinder during operation and automatically conveys them into the designated scale collecting tank. Scale deposits are thus continuously removed from the steam cylinder.

A technical innovation that solves the scale problem

Advanced steam cylinder design lets in-house staff remove scale easily. Deposits fall into a collection tank that can be drained without opening the unit. Regular removal improves performance, lowers service needs, and prevents drain blockages.

Cold water pool protects inlet and outlet from scale

Near the in- and outlet connections, the twin walled cylinder design of the unit creates a cold water pool which always remains below the temperature of scale formation. Water in- and outlet are therefore protected against scale deposition.

Robust outdoor housing for external installation

The weatherproof powder coated galvanized steel housing allows the Condair OC to be installed outdoors. This saves valuable indoor space and ensures reliable steam humidification even in challenging environments.

Steam distribution options

With steam hose for in-duct or blower pack for direct room humidification. The Condair steam pipe ensures optimal steam distribution with precise humidity delivery. Designed for efficient performance, it provides reliable indoor air quality and consistent humidification results.

Frequently asked questions

How accurate is humidity control with the Condair RS?

How does the Condair RS manage scale and how easy is maintenance?

The Condair RS features an integrated scale management system. Limescale is automatically separated from the stainless-steel cylinder and collected in an external scale tank, which can be drained at the push of a button. This makes maintenance quick and easy.  In addition, the cold-water pool design prevents blockages in the water inlet and drain by keeping these areas cool.

What control and automation options does the Condair RS offer?

The Condair RS comes with a touchscreen controller for intuitive operation, providing full access to system parameters, service reminders, and automatic safety shutdowns.  It also supports seamless integration with building management systems (BMS) via BACnet (IP and MSTP) and Modbus as standard. A USB port allows trend and fault data logging as well as software updates.

Quotes from our customers

Harrier GroupJeremy RawleySafety and Facilities Manager

We already knew Condair, as we have a couple of their units in other print rooms. The quality of their equipment is right up there. Paper is susceptible to changes in environmental conditions so humidity is really important. Their service is second to none as well. We work to tough deadlines and one of the key things for us is that Condair could supply the equipment quickly within the required timescale.

Having a local service engineer on call to maintain them in tip-top condition is important for us too.

Sporting Edge UKDave VincentManaging Director

...we have standardised our humidity control using the Condair RS steam humidifier. It provides us with a dependable, controllable product that will happily work with standard mains water. We also love the self de-scaling feature.

Steinway & Sons, UKCraig TerryManaging Director

Incredibly rare and expensive wood is used in some of our models – but actually any type of wood is susceptible to changes in environmental conditions. Dryness is the enemy of pianos so humidity is really important. We need 40% to 50% humidity all the time to protect the wood, whether they’re in the showroom or the workshop. Condair’s units are ideal for the job.

And because we rely so heavily on the reliability of the humidifiers, we also contracted with Condair to service the humidifiers at regular intervals. Would I recommend Condair? Oh yes, they’ve supplied great service.
