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.
