Shell and Tube Heat Exchanger System for Air Compressor Waste Heat Recovery

Shell‑and‑tube heat exchanger system designed to recover waste heat generated by industrial air compressors. It captures high‑temperature heat from compressor hot oil or compressed exhaust air, and transfers heat to water for hot‑water production. Reclaims otherwise wasted thermal energy, cuts boiler energy consumption, suitable for factory heating, process hot water, cleaning and domestic hot‑water supply.

Working Principle

High‑temperature medium (compressor lubricating oil / hot compressed air) flows through one side of the shell‑tube exchanger. Cold process water flows through the other side. Heat transfers from the hot compressor medium to water. The cooled oil / air returns back to the air compressor circulation loop. Heated water is stored in buffer tank for onsite usage. The complete system includes shell‑tube heat exchanger, connecting piping, valves, temperature sensors and circulation accessories.

Key Features

- Shell‑tube construction, high heat transfer efficiency for continuous compressor waste heat recovery

- Customizable per compressor power, oil flow rate, target hot‑water temperature

- Material selections: carbon steel shell, stainless steel / copper tubes, anti‑fouling design

- Tolerates oil contamination, high temperature and pressure fluctuation from air compressor operation

- Easy maintenance: removable tube bundle for inspection, fouling cleaning

- Complete system solution: match valves, temperature monitoring and safety bypass loop

- Reduce factory energy cost, realize waste‑heat utilization instead of heat dissipation via cooling tower

Typical Applications

- Screw air compressor waste heat recovery

- Large industrial reciprocating air compressor heat reclaim

- Factory process hot‑water preheating

- Workshop heating, facility domestic hot‑water supply
