Is the SKR safe for residential use?

Yes. The SKR is a product designed for residential and small commercial spaces, equipped with low-voltage safety systems. Dry-run protection and overheat protection are standard.

Is the SKR capacity sufficient?

The SKR is designed for typical residential and small office spaces with a capacity of 3–5 kg/hr. For larger spaces, the SKE4 or other industrial models are recommended. You can use our contact form for capacity calculation.

What is the permanent cleanable chamber?

Instead of using plastic cylinders, the SKR has a permanent stainless steel chamber. This chamber can easily be removed and cleaned once or twice a year; it does not require replacement and provides long-term cost savings.

Typical Installation

Duct and Fan Distribution Options

The SKR humidifier is typically used with a dispersion tube installed through a duct. However, we offer fan distribution installations as well for applications where a duct system is not available.

1 On/Off humidifier complete with 1 remote alarm dry contact

1 dry contact to start the HVAC fan on a call for humidity

1 S.A.M. stream absorption manifold for duct distribution

6 ft (1.8 m) flexible steam hose for steam distribution

System Overview

System Components

Evaporation Chamber

Evaporate Water, Not Money!

The Neptronic SKR humidifier includes a permanent, reusable stainless steel chamber instead of a disposable plastic bottle that must be replaced at least once a year, resulting in thousands of dollars of savings. These savings will more than pay for the initial cost of the humidifier.

Duct Distribution

Duct Distribution Installation

For a duct distribution installation, the SKR requires a S.A.M. Steam Distribution System to disperse steam.

S.A.M. Technology

Stream Absorption Manifold

Short absorption distance (less than 155 cm)
Stainless steel tube with brass nozzles
Nozzles prevent condensate from escaping the duct
Inclined steam dispersion tube to return condensate back to humidifier or steam trap

S.A.M.: For models SKR4E and SKR5ES.A.M.E2: For models SKR3E

Fan Distribution

Fan Distribution Installations

The fan distribution installation option is ideal to supply steam directly with an SDU (steam distribution unit) into a room without a duct network or for a localized area.

Common Features of SDU

Quiet steam distribution

Powered and controlled by the humidifier

Air pressure switch included

Fan will keep running for four minutes after steam production has stopped to prevent any condensation

Integrated SDU

Integrated Steam Distribution Unit

This option is typically used in small stores, small warehouses and laboratories where the visibility of the unit is not an issue.
