2. GTR Rotor What does GTR stand for: What is it’s composition:
Gerry Trembly Rotor
What is it’s composition:
Combination SIGEL and Molecular Sieve
Where can it be used:
Coke Drying/Foundries
Spray Dryers
Fluid Bed Dryers
and more…

3. GTR Rotor What are it’s advantages: What are it’s disadvantages:
Better gr/lb depression with untreated outside air (high temp and moisture)
Able to deal with higher reactivation inlet and outlet temperatures
What are it’s disadvantages:
Requires high temperature reactivation energy source:
Direct Fired Gas
High Pressure Steam (150 PSIG+)
Because of the larger gr/lb depression, higher process outlet temperatures (advantage for some applications)
Not selectable in the ICA software by reps. Need to have your applications engineer provide performance runs.

5. Spray Drying and Fluid Beds

6. Spray Drying and Fluid Bed Problems
Production rate varies by season
Drying time too long
Inconsistent quality of the powder
Production stops
Product scrap
Lack of flexibility
Lots of customer use direct fired gas to heat ambient to °F

7. Typical Production Losses Related to Moisture

8. Munters Approach
Using desiccant technology to dry the outside air required for the process (GTR)
Provide a consistent low dew point (winter time conditions year round)
Desiccant wheel removes moisture while also heating the process air (energy savings)

Reactivation Usage (summer): Process Savings (summer):
BTUH = ((6390) * (1.08) * (325-84)) / .92 BTUH = ((10,000) * (1.08) * (200-89)) / .92
BTHU = 1,807,800 btuh input BTUH = 1,303,043 btuh input
Net Gas Used For Dehumidification = (1,807,800 – 1,303,043) = 504,757 Input
Therefore (Net): 504,757 btuh / lb water removed = 707 btu / lb water removed

Actual Gas Used For Re-Heat = ((10,000) * (1.08) * (200 – 30)) / .92 = 1,995,652 btuh
Therefore: Gas Usage = 1,995,652 btuh
Cooling Usage = 118 Tons
(NOTE: Does not account for cooling inefficiencies (COP and defrost) for cooling below the freezing point of water)
*NOTE: Higher gr/lb discharge because of the added moisture from the direct fired heater

14. Energy Analysis (Cont.)
For New Jersey:
Target = 40°F DP, constant outlet gr/lb, 10,000 CFM of outside air
$127,035 Cool / Reheat
$76,081 Desiccant Dehumidification
$50,954 Savings for DH vs. Cool/Reheat

15. Who is the Competition?
Doing nothing. No humidity control means lack of quality control.
Cool/reheat systems
Require more energy
Other desiccant dehumidification manufacturers
Don’t have GTR

16. Who Should We Sell to? End users of the following industries:
Dairy (powdered milk)
Fragrance Companies
Flavor Companies
Gelatin
Whey and other proteins
Any powdered product that is spray dried (meats, fats, broth powders, etc.)

18. How Do Technical Details We Sell
Simple Questions:
Is your production better in the winter time than the summer time?
If Yes, we can help.
Would our operations be improved if we could create winter time conditions year round?

19. What Do We Need to Know
What is the total CFM that you need for your process (making sure they include wall sweeps, etc.)?
What do you have for reactivation energy?
Understand your customers AHU requirements (construction, filtration, fan requirements).

20. Tools
Show the customer that we can supply winter time condition year round
Show the customer how much water you are preventing from entering the spray dryer or fluid bed

21. COKE What are we talking about?
A Cupola or Cupola Furnace is a Melting Device used in foundries
Diameters can be 18” – 13’ (round)
Coke is a heat source used
Coke is a high carbon coal.
Air is fed through “Tuyeres” to the Coke
Typically, raw outside air
Metal is placed inside the furnace at the top
The metal melts, has a chemical reaction with the COKE and other chemicals that may be added, and the liquid metal is removed at the bottom
Electric Induction Furnaces are also used in foundries, they do not require dry air

22. Typical Cupola

23. Technical Details
Lower gr/lb depression is achieved when lower face velocities are used
Example, 10,000 CFM through a 15,000 wheel
When looking at bin data, don’t concentrate on the highest gr/lb bin
Production improvement will be the targeted sell point
If energy is your story, make sure you work with your applications engineer on maximizing the performance

24. Coke
For every lb of moisture that enters the blast, an additional 1.19 lbs of coke is required
Coke is currently priced at $ to $560.00/ton (can vary)
The higher the outside air (ambient) moisture level, the more coke required to perform the same work

25. Munters Approach
Using desiccant technology to dry the outside air required for the process (GTR)
Provide a consistent low dew point
Desiccant provides moisture removal required without cooling (industry does not want to deal with chillers or DX systems)

32. How We Do the Energy Analysis
Select the bin data for closest city:
Hours represent 10 hr/day operation per the parameters
(total 2,860 hr/year)

33. How We Do the Energy Analysis
Optimize the system based on first cost, savings and possible energy recovery options (use your Applications Engineer)
Perform the runs for each bin and complete the analysis
Summary

34. How We Do the Energy Analysis
If we have the competitions performance, we can compare:
Competition doesn’t know about using TW for post cooling (keep secret)
Did not have, so assumed equal (with PowerPurge™, we should be less)
The customer gave us Bry-Air’s performance
We were provided their BHP

35. What Do We Need to Know:
What is the total CFM that you need for your process?
How should the Munters unit interface with their existing operation?
What do you have for reactivation energy?
What other utilities are available?

36. Industry Details Old Established Industry:
They have been doing it this way for decades, why change now?
First Cost Challenged Industry:
They do not like to spend money
Difficult to Establish Who are the Right People to Talk to
Site Utility Manager
Project Engineer
Technical Director
Engineering Manager
Melt Superintendent

37. Customer Details Listen to your customer:
Understand their concerns
Work with them to use the different Munters technologies that we have:
GTR
Heat Exchangers
Using Tower Water
Keep it simple if it needs to
be because of cost or other factors
Help them find out if grant money is available!

38. Market Strategy Be first to the customer:
This is actually not a new application (unit sold in 2004 was a replacement of HTS unit)
We have seen Bry-Air in this industry
Understand our competitive advantage:
Competition might not have the same gr/lb depression, but can try to make up for it on first cost
Create specifications around Munters, and make the competition match

39. Tools
Energy Analysis

40. What Do We Sell? Fully Welded Construction (discharge can be 200°F):
HCD if CFM < 12,001
IDS if CFM > 12,001 or a complex system
GTR Wheel
Better gr/lb depression with raw outside air
Basic Controls
Reactivation control
Face and bypass is outlet gr/lb level is critical (expensive sensor option, difficult control)
High Temperature Reactivation Utility
Direct Fired Gas
High Pressure Steam (min 150 PSIG)
High Reactivation Outlet (140 – 150°F)

41. Additional Opportunities
Look for Possible Energy Recovery Opportunities:
Possible reactivation outlet to process inlet
Spray dryer exhaust for additional post heating
Applications to look for
Applications that can deal with higher process outlet temperature
Applications looking for +/- 40 gr/lb and lower
