Bare Tube Biogas Cooler Heat Exchanger for Biogas Plant Gas Conditioning

Biogas generated from digesters contains large amounts of water vapor plus corrosive components such as hydrogen sulfide. Without proper cooling and moisture removal, wet biogas will cause corrosion on biogas engines, pipelines and downstream equipment, bringing extra maintenance cost for biogas plant operators.

As a practical solution, bare tube biogas cooler heat exchanger is widely adopted for biogas cooling and biogas dehumidification in small‑to‑medium biogas projects, landfill biogas systems and wastewater biogas treatment sites. Different from finned tube heat exchangers, this bare tube heat exchanger uses smooth bare tubes for gas‑side heat transfer. It avoids fouling blocking risks when handling dirty, moisture‑rich biogas streams, which makes routine cleaning much easier for site operators.

Our bare tube biogas cooler can be built with stainless steel bare tube bundle against biogas corrosion. It works for biogas condensate removal: when hot raw biogas passes through the bare tube biogas cooler, vapor condenses into liquid water, and condensate drains out from the bottom drain port. This simple process lowers biogas dew point and protects biogas CHP units and biogas compression equipment from wet gas damage.

We provide custom‑built bare tube biogas cooler heat exchanger according to customer working parameters: biogas flow rate, inlet & outlet temperature, operating pressure and material requirement. No over‑complicated structures, focus on stable field performance and easy on‑site maintenance.

This type of biogas heat exchanger fits for new biogas plant construction as well as retrofitting existing biogas cooling systems. Customers from biogas energy projects can send over their process data for quotation and technical discussion.
