Electric Steam Humidifier With Steam Distribution Unit
The amount of humidity required in a home depends to a certain extent on the way it is constructed. A well insulated house with vapor barriers in walls, ceilings and slabs and properly fitting storm doors and windows may require only couple of galolons of additional moisture per day to maintain the proper relative humidity. A house of same size but loosely constructed may need five times as much moisture in the same period.
If your home winds up with too much humidity, it can incease the growth rate and spread of a wide variety of molds. It will also greatly accelerate the rotting process of many woods and other structural materials.
Humidity not only affects your home itself, but also a wide variety of contents. Low humidity is the main cause of static electricity in a home. Dry skin and dry carpets are great for creating the friction required to send sparks from you fingertips into anything you touch. With all the highly sensitive electronics equipement (from stereos and tv's to computers) in homes today, static electricity can be a major threat. It doesn't take much of a spark to harm that expensive piece of electronics.
A newly developed NEP steam-distubution unit for stand-alone electric steam humidifiers offers unprecedented precise humidity control in any size room or buildeng where ventilating ductwork is not present. The steam is discharged with a quiet fan blower (available in 3 sizes) directly into the area.
In addition, in order to prevent the accumulation of condensation in air ducts, NEP has designed 2 basic configurations of steam distribution to provide the client with the most economical solution for any particular application.
Distribution manifold systems are to be used to prevent condensation in air ducts (available in 3 types of manifolds) .
1. “MULTI-STEAM”; where absorption distances are very short.
2. “S.A.M.”; where absorption distances are short.
3. “S.A.M.E.”; where duct dimensions are restricted.
The SDU Steam Distribution Unit can be used with either SK-300 or SKR electric steam humidifier. The self contained SK300 steam humidifiers produce mineral free, odourless, sterile steam without the replacement cost associated with electrode cylinders manufactured by competitors.
SK-300 Electric Humidifier has the following features:
• Capacities from 6-180lb/hr (2.7-82kg/hr) of steam
• On/Off or fully modulating with solid state relays
• BACnet interface capability
• AFEC system, mass measuring water sensor.
• Permanent stainless steel chamber with self cleaning heating elements
• Simplicity of operation and service
• Corrosion and scratch resistant aluminium housing with powder paint finish
• Wall mounted installation
The SKR humidifier is easy to install and provides a simple and reliable operation with the user friendly control package. Steam is produced in a permanent stainless steel chamber which is easily removed and re-installed for rapid servicing. No plastic cylinders to replace, making it more economical to operate and environmentally friendly than the electrode humidifier.
• No expensive plastic cylinders to buy
• Environmentally friendly - no plastic cylinders to throw away
• No more blocked drain solenoid valves
• Drain water tempered to below 14 degrees

how do I know if my relay is bad on my split heat pump unit?
I had two wires which were rubbing together which caused them to short out. We replaced the wires and the end connectors. Now the air cools for the cooling option but now the fans will not shut off. The air in the house stops running but the fans still do not. Also, if we turn off the thermostat there is warm air generated and pushed into the house through the cold air duct.
There are lots of wires in a heat pump. Two of them being shorted together is likely your problem cause but without being able to actually look at it it is impossible to diagnose. To determine if the relay is bad you would need an ohm meter. Place the leads on either connecter of the switching portion of the relay. Then apply 24v to the coil portion of the relay. If the ohm meter starts beeping or shows zero ohms your relay is good. Now remove the 24v and the ohm meter should stop beeping and show OL. Or you can just do what most of us do and replace it with another $2 relay.
