SKS4 Documentation

SKS4 - Overview

The SKS4 humidifier provides chemical free steam by using an on-site central boiler or steam generating station as a heat source. The raw steam under pressure from the boiler provides the energy to produce clean, sterilized steam through a heat exchanger.

Environmentally friendly
Optimize the use of boiling water – no unnecessary drain!
Ease of maintenance with comprehensive scale management system

Advantages of Steam to Steam Humidifiers

Capacities from 17 to 1250lbs/hr (8 to 570kg/hr) of steam
Stainless steel (for raw steam) heat exchangers
Ease of servicing: clean and re-install within minutes
Patent-pending water level detection system using 2 sensor technologies
Comprehensive scale management system
Uses either domestic, RO or DI water
For Multi-Steam and SAM in-duct distribution systems
Available with BACnet MS/TP or Modbus communication
Optional ethernet module for BACnet IP or Modbus IP, and web services
Patented Anti-Foaming Energy Conservation (AFEC) System
Drain water tempered to below 140°F (60°C)
Now available with an OSHPD option – the SKS4 meets the requirements of OSHPD Special Seismic Certification Preapproval (OSP)
Supplied with Neptronic actuated globe valve, giving full modulation control of low pressure steam

Linear Actuated Globe Valve

The Neptronic electric linear actuated globe valve provides a modulating output for close humidity control. Each unit comprises a linear actuator that is directly coupled to the valve. The SKS4 sends an analog control signal to the actuator to open and close in proportion to the demand of steam.

Electronic feedback from the actuator allows the SKS4 controller to monitor the exact position of the valve
Failsafe feature closes the valve when there is a power failure
Delivers a maximum of 100 pounds (450 Newtons) force at rated voltage
Sizing ranges from 1/2 inch to 2 inches (15mm to 50mm).

For low pressure steam applications, it is necessary to shield the actuator from heat generated by the valve. This is accomplished by a factory installed adapter kit, the DDSTM.

System Overview

In-Duct Distribution

For Multi-Steam^TM SD/HD and S.A.M. in-duct distribution systems.

Efficient and economical, S.A.M. and S.A.M. E2 systems are suitable for installations where absorption distances are short (less than 5ft/1500mm) and/or low/restricted duct temperatures are in effect
Custom-made to the dimensions of the duct or AHU, the Multi‑Steam™ SD/HD systems are used at critical locations within the air handling systems where absorption distances are extremely short (less than 3ft/900mm) or where low air duct temperatures are present
