Are You Serious About Reducing
Your Energy Cost and Increasing
Operational Efficiency?

If You Are, Then It’s Important To Do The Things That Are Easy And Will Give You The “Biggest Bang For Your Buck”; Installing Cottonwood Filter Screens Is One Of Those Things – They Will Keep Your Equipment Clean And Running Efficiently So You Can Get Every Ounce Of Energy Savings From It.

That’s Easier Said than Done.

If your Facility is operating with a “Lean” Budget &
Maintenance Staff, It Can Be Difficult and Sometimes
Impossible to Capture All of The Energy Savings Because
You Simply Don’t Have the Money or Hands Available to keep
up with the maintenance that needs to be done.

If This Is Your Situation, Then Using Cottonwood Filter
Screens Will Definitely Help You. After Seeing the Energy
Savings Below, Be sure to visit the section on this site called
“Reducing Maintenance Time” You’ll Be Amazed How
Cottonwood Filter Screens Will Reduce Your Maintenance
Time & Effort!

Important Points to Think About:

  1. Every Day That Your Chiller / Condenser Unit
    Operates it takes on debris load and Runs at an
    Increasing Level of Inefficiency. That means that
    Each Day Following a Coil Cleaning, Your Chiller /
    Condenser unit is Costing You More Energy Dollars
    than the Day before until the Next Coil Cleaning!
  2. High Efficiency Equipment is only as efficient as the
    Coils are Clean. Replacing Old Equipment with
    New High Efficiency Equipment doesn’t guarantee
    that you’ll reap the Efficiency & Energy Saving
    Benefit. “Micro Channel Coils” typically used in high
    efficiency condenser systems Increase the Coil Fin
    Density so as to increase the heat rejection surface
    area; this reduces the air space between each fin,
    making them prone to Rapid Fouling – keeping
    them clean is an imperative in order to realize the
    efficiency and energy saving benefit.
  3. “Going Green” without “breaking the bank” typically
    requires stepping-up maintenance practices on
    existing equipment and replacing old equipment
    only when it can no longer provide the efficiency
    needed even under the best of maintenance

Energy Saving Calculator

The Following Energy Cost Calculator is designed to Show General Savings at Various
Energy Rates as Applied to Various Tonnage Ratings.

Due to many variables affecting
energy costs from region to region, the information from this chart should only be used to get
a directional

sense of benefit from operating a clean vs. dirty condenser coil.
