HVAC Systems: Facility heating, cooling, and air handling
These systems play a critical role in improving energy efficiency, reducing operating costs, and maintaining process stability.
Used Heat Exchanger Buying Considerations
When selecting a used heat exchanger, it is important to evaluate both process requirements and equipment condition:
Condition & Maintenance History: Review refractory lining, heating elements, and prior use
Heat Transfer Requirements: Evaluate temperature differences and thermal duty
Fluid Compatibility: Ensure materials match corrosiveness and cleanliness requirements
Pressure & Temperature Ratings: Confirm suitability for operating conditions
Design Type: Shell & tube, plate, or air-cooled based on application
Fouling & Maintenance Needs: Consider ease of cleaning and maintenance
Condition & Service History: Review wear, scaling, and prior usage

Sell Your Used Heat Exchangers
Aaron Equipment actively purchases surplus heat exchangers, including shell & tube, plate, and air-cooled systems. Whether upgrading equipment or decommissioning assets, our team can help maximize value.
A heat exchanger is a system that transfers heat between two fluids without mixing them. It is used to heat or cool process streams in industrial applications.
Common types include shell and tube, plate, air-cooled, scraped surface, and spiral heat exchangers. Each type is designed for specific heat transfer requirements and applications.
Choosing the right heat exchanger depends on temperature requirements, fluid properties, pressure conditions, and required heat transfer efficiency.
Yes. Used heat exchangers are built for long service life and can remain highly reliable when properly maintained, cleaned, and inspected.
Heat exchangers are used in chemical processing, food production, energy, pharmaceuticals, and HVAC systems where temperature control is critical.
