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…

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.

Spray Drying and Fluid Beds

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 200-400°F

Typical Production Losses Related to Moisture

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)

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

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

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.)

Europe's Customer Base Whey Lactalis 4 units Milk CPS Germany Celia (for baby) 2 units Sevres 1 unit Starch Roquette 6 units Yeast Lesaffre 5 units Kerry 1 unit Scotland Baby foods Kerry 3 units Malaysia Kerry Penang Food Colorant Roche Vitamines 1 unit Coffee Nestlé 3 units Soup Leibig 1 unit Aroma Aromes de Bretagne 1 unit Seaweed Sea Oil 1 unit Mix Bionov 1 unit

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?

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).

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

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

Typical Cupola

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

Coke For every lb of moisture that enters the blast, an additional 1.19 lbs of coke is required Coke is currently priced at $480.00 to $560.00/ton (can vary) The higher the outside air (ambient) moisture level, the more coke required to perform the same work

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)

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)

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

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

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?

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

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!

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 http://www.thefreelibrary.com/_/print/printarticle.aspx?id=54577386 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

Tools Energy Analysis

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)

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 Open discussion
