3. Brief History
Cargocaire (CEC) was founded in 1939 by Commander Colvin to protect cargo aboard merchant and naval vessels.
Munters Corporation was founded by Carl Munters in The two companies merged to create Munters Cargocaire.
Nick Des Champs develops air-to-air counter flow heat exchanger in 1973 for cooling jet fighter cockpits. Des Champs Laboratories incorporated in 1974.
Munters acquires Des Champs Technologies in 2007.

14. Dew Point Control Foundries
Provides dry air to increase fuel consumption

15. 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.

16. Typical Cupola

17. Typical Cupola

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

19. What Does That Mean?
If O.A. contains 132 gr/lb, and the Cupola requires 9,000 CFM, then 764 lb of H2O are introduced per hour.
This means 909 lbs of additional Coke is required
If 9,000 CFM at 132 gr/lb can be reduced to 77 gr/lb.
Only 530 lbs of additional Coke is required, a savings of $106 / hour.
Example (2) 8-hour shifts for 5 days a week:
Coke Savings = Greater Than $350,000 / year
Energy Required = $50,000 / Year

20. Munters Approach
Using desiccant technology to dry the outside air required for the process.
Provide a consistent low dew point.
Desiccant provides moisture removal required without cooling.

Average energy cost / hour = $12.2
Average Coke Savings / hour = $90
Assuming (2) 8-hour shifts, 5 days a week:
Payback = 4 Months for equipment

23. Cupola Dehumidification Process

24. Energy Savings
For Every 1,000 CFM required in the Cupola, about 35 lb/hr of Coke can be saved, or $11.8/hr (assuming 55 gr/lb depression).
For a typical 30,000 CFM System, this means:
1,050 lb/hr of Coke can be saved, or $294/hr (values do not include unit operating energy, estimated at $54/hr)

27. What Do We Sell? Fully Welded Construction: GTR Wheel Basic Controls
HCD if CFM < 12,001.
IDS if CFM > 12,001 or a complex system.
GTR Wheel
Better gr/lb depression with raw outside air.
Requires higher reactivation heated to temp.
Basic Controls
Reactivation Control
Face and Bypass outlet if gr/lb level is critical (expensive sensor option, difficult control).
