Model 8525
Mixture Range
0-100% carbon dioxide in nitrogen
Mixed Gas Flow Capacity 0-750 scfh (0-20 Nm3/h) This is the mixed gas capacity at the mid-range setting. The capacity may be more or less depending on the mixture setting. Consult Thermco for more details.
Gas Mixing Accuracy
±2% CO2 absolute over 50°F to 80°F (10°C to 27°C) ambient temperature range
±3% CO2 absolute over 40°F to 104°F (4°C to 40°C) ambient temperature range
Stated accuracies assume that the input temperature of the gases are equal
Gas Analyzer Thermal conductivity type made by Thermco. The detector is expected to last the lifetime of the gas analyzer. The calibration is highly stable, recommended calibration interval is one year.
Ambient and Supply Gas Temperature Range 40°F to 104°F (4°C to 40°C)
Standard Supply Gas Pressure 100-125 psig (6.9-8.6 barg) Supply pressures do not have to be equal.
Standard Mixture Outlet Pressure 10-50 psig (0.7-3.4 barg) Regulator provided by Thermco in gas mixer for mixture outlet pressure adjustment. Note: Gas mixers are frequently engineered for non-standard pressure conditions.
Gas Connections ½ inch NPT female pipe for nitrogen, carbon dioxide and mixed gas.
Surge Tank 5 gallon, ASME coded and CRN registered, pressure relief valve provided
Surge Tank Pressure Switch Solid-state sensing and output, rated 100,000,000 cycles

Additional Information

Application

The Model 8525 is designed to precisely mix carbon dioxide and nitrogen for food packaging. With a range of 0-100% CO2 in N2, the 8525 can mix any proportion of CO2 in N2.

The gas mixer is enclosed in a NEMA 4X stainless steel enclosure which enables the gas mixer to be mounted in a washdown area. A built-in gas analyzer continuously monitors the gas mixture being created. Alarms on the gas analyzer may be set by the user to alert personnel if the gas mixture is out-of-specification. An alarm will energize a horn and light when an alarm occurs.

The 8525 is specially cleaned for food service.

Because the gas mixer uses a surge tank design, this type of system is ideal for applications that require maintaining a precise proportion from zero flow to full flow with high reliability. The 8525 is suitable for continuous flow or intermittent flow demand.

Thermco Surge Tank System

All Thermco gas mixers use a surge tank. The Thermco surge tank system has the significant advantage of maintaining the accuracy of the gas mixture from zero to full rated flow rate. There is no “minimum” flow rate. Gas mixing systems without a surge tank will have a minimum flow rate below which the gas mixture becomes inaccurate. The Thermco surge tank system is able to accomplish this accuracy without complex control valves or flowmeters.

Supply Gas Systems

Gas mixers will be made for supply pressures of 100-125 psig (6.9-8.6 barg) and mixed gas output pressures of 10-50 psig (0.7-3.4 barg) unless ordered otherwise. Gas mixers are often made to special pressure conditions; consult Thermco for details.

Warning

Improper use of this product can cause death, serious injury, or property damage. Personnel dealing with this equipment should read and understand warning labels and instruction manuals provided by Thermco. Only personnel familiar with industrial gases should attempt to install or service this equipment. Gases are under pressure and therefore the hazards associated with pressurized systems exist. Gases from high pressure cylinders must be reduced to the specified pressure before entering the gas mixing system to prevent the possibility of equipment damage and personal injury.

Only use oxygen in gas mixers specifically designed for oxygen service. Gas mixers not designed for oxygen service cannot be converted to oxygen service.

Flammable, toxic, liquid or corrosive gases should not enter these gas mixing systems.
