SKRO - Overview

Overview

Optimize Humidification with RO Filtration

The Neptronic SKRO is a scalable reverse osmosis water treatment system tailored for adiabetic and isothermal Neptronic humidifiers. It is designed to purify water for atomizing applications, and eliminate maintenance on electric, gas, and steam to steam humidifiers. The Neptronic SKRO purifies water using a semi-permeable membrane to remove impurities, dissolved solids, salts, bacteria, and viruses. By applying pressure, water is forced through one or multiple membranes, ensuring exceptionally pure water through advanced filtration.

Designed to fully support Neptronic’s humidification range, the SKRO is available in multiple capacities:

Why you need our SKRO?

The Neptronic SKRO Reverse Osmosis system is your best defense against scale buildup and high maintenance costs. By removing nearly all of the dissolved minerals, it protects your humidifier, ensures cleaner steam, and boosts energy efficiency. Designed to integrate seamlessly with Neptronic humidifiers, the SKRO keeps your equipment running smoothly and your indoor air at its best. Less cleaning, more performance-just pure, smart humidity control.

Neptronic Reverse Osmosis Systems ensure maintenance-free operation of our isothermal humidifiers (SKE4, SKG4, and SKS4) and are an integrated component of our adiabatic high-pressure spray SKH4.

Neptronic WP series reverse osmosis systems are available with an array of storage and pre-treatment options. We understand every installation is unique, and our experts can help tailor a water treatment approach to a humidification project.

  • Available in capacities up to 4500 lbs/hr, and voltages ranging from 120/1-ph to 600/3-ph
  • Activated carbon, softeners, and anti-scale injection pretreatment
  • Painted galvanized steel closed enclosure and stainless-steel membrane vessels
  • Pressurized tank to prevent outside contamination
  • Humidifier functionality can engage RO during offseason to prevent stagnation.

Advantages of using water treatment systems for Neptronic humidifiers

  • Eliminate maintenance on multiple humidifiers with single RO system.
  • Reduce frequency of drain cycles to improve uptime for critical operations
  • Prevent foaming in humidifier tanks

System Overview

  • Digital pressure and flow gauges
  • Low pressure pump protection
  • Integrated pressure controls for pressurized accumulation tanks

Pretreatment

Several accessories are required to complete the water treatment system. In most water qualities, a softener or antiscale injection is required to pretreat the water upstream of the RO system. This ensures RO membranes do not scale over. Large capacity activated carbon filters prevent chlorine from oxidizing reverse osmosis membranes.

  • Single and twin softeners
  • Antiscale Injection
  • Standalone Activated carbon tanks

Storage

Storage is also a key component of the water treatment system. There should be enough buffer to ensure humidifier boiling chambers can fill rapidly.

  • Pressurized accumulators from 15 to 120 gallon
  • UV Post Treatment
