Last week we reviewed the types of steam humidifiers normally supplied in building HVAC systems. Creating the steam is simply the first step. Now we …
Types of Isothermal Humidifiers: Humidification Basics Part 12
Isothermal humidifiers are the overwhelming choice in building HVAC systems. This week’s R. L. Deppmann Monday Morning Minute talks about the various types of isothermal …
Humidification Specification and Steam Absorption Distance: Humidification Basics Part 11
In humidification systems, we know that steam absorption distance is important. We also know that various distribution methods have different required absorption distances. How do …
Steam Absorption Distance: Humidification Basics Part 10
What is humidification steam absorption distance, and why is it critical in humidification applications? Absorption distance is the length of duct that is required to change …
Importance of Water Quality and Type: Humidification Basics Part 9
Water quality is an important concern when it comes to humidification. Regardless of what type of humidification you’re using (isothermal or adiabatic), chances are you …
Adiabatic Humidification: Humidification Basics Part 8
Recently, we discussed isothermal humidification. Today, we’re going to talk about the other method of humidification, which is called “Adiabatic.” Adiabatic humidification puts water (not steam) …
Steam Isothermal Humidification: Humidification Basics Part 6
In many ways, Psychrometrics is like a Rubik’s Cube. Change one thing, and you automatically change something else. But instead of shifting colored cubes around, …
Steam Vent Operating Pressure
I have a 15 psig steam system which operates at about 7 PSIG most of the time. Is the Hoffman Main Steam Vent Model 75 appropriate for this application with its listed 15 psig maximum?
Can I change my Vacuum Condensate Pump to a Simple condensate Pump? (Part 3)
When you use the word vacuum with most people, they think of sucking something up like a vacuum cleaner does. There are times that vacuum condensate systems were used to lift or “suck up” the condensate from a lower level. Today, we will examine the use of vacuum condensate pumps to lift condensate from a low return.
Can I change my Vacuum Condensate Pump to a Simple condensate Pump? (Part 2)
We began a series about vacuum condensate units and introduced one of their uses: the reduction of time to bring a building up to temperature …
