HVAC Materials Selection

Selection of materials for engineered products to optimize reliability,manufacturability, cost and availability

Corrosion Resistancecopper

Design for corrosion resistance in difficult applications.

Materials Processing 

Once materials are selected, either in the original component design or when alternatives are suggested as the result of a failure analysis, GEA can provide assistance in selecting the best way to process those materials.  We can help you decide whether to

  • cast,
  • forge or
  • fabricate a product. 

We can help you find the best

  • heat treatments,
  • coatings and
  • joining processes

and we can help you understand how those processes impact the cost and functionality of your product.

Heat treatment

Development of heat treatment processes for ferrous and non-ferrous metals to improve material strength, toughness, wear resistance and corrosion resistance.

Bearing metallurgy 

Selection and processing of specialized materials used in rolling element and plain bearings. Development of tribological tests for bearing materials

Sheet Metal Forming

Selection of materials for sheet metal forming applications including deep drawing, bending and stretching. Application of circle-grid analysis to facilitate application of appropriate materialsBrazing-Welding


Selection of brazing filler metals and processing to join a wide variety of metals used in HVAC equipment.

Manufacturing Solutions

Machining, metal forming and joining problems slow production and cost money. Determine the cause of bottlenecks in your manufacturing process and eliminate them. Visit the Manufacuring Process Improvement page for additional details.

Chemical Evaluation

Evaluate chemicals used in your product and residual process chemicals used in manufacturing and cleaning parts.

Refrigerants, Oils and Materials

Determine appropriate selection for refrigerant, lubricant and metals combinations. Determine compatibility of electric motor insulations, elastomers and other materials with refrigerants and lubricants. Evaluate new refrigerants in regards to environmental properties, thermodynamics, toxicity, flammability, compatibility and other properties. GEA also has experienced design engineers who can help you select the right refrigerant for your product(s). 

Supplier selection

Evaluation, selection and development of suppliers for raw materials as well as cast, forged, machined, formed, heat treated and coated components used in engineered products.

Failure Analysis

Determination of failure causes for components and for complex machinery including air conditioning compressors, chillers, unitary products, fans, air handlers, earthmoving equipment, diesel engines, transmissions, electric motors, rolling element and plain bearings.
