Air Cooled Heat Exchangers from Heft Engineers are engineered solutions designed to efficiently dissipate heat from industrial process fluids using ambient air as the cooling medium. Built with precision, our exchangers optimize heat transfer without the need for large water infrastructures, making them ideal for locations with limited water availability or where water conservation is a priority. With durable materials, custom finned tube designs, and reliable fan & support mechanisms, our air cooled heat exchangers deliver high performance, low maintenance, and long service life.
Features
High Thermal Efficiency: Optimised fin geometry and multiple tube‐row arrangements maximise surface area for superior heat exchange.
Fan & Ducting Setup: Install fans (forced or induced draft) in line with manufacturer’s recommendations; ensure proper alignment, balancing, and guarding. Include screens or filters to prevent dust, debris, or insects entering finned sections.
Piping & Fluid Connections: Properly connect inlet/outlet fluid nozzles; ensure good sealing; provide adequate supports and expansion joints for thermal expansion..
Control & Monitoring: Install thermocouples / RTDs to monitor inlet/outlet temperatures; vibration sensors for fan assembly; optionally variable speed drives for fan motors to adjust airflow vs heat load.
Commissioning: : Gradually bring the system online; monitor for leaks, airflow resistance, and thermal performance; adjust fan speeds or airflow dampers if included.
Maintenance Practices: :Periodic cleaning of fins; lubrication of fan bearings; checking belt tension (if belt‐driven); inspecting fan blades & motors; replacing worn or corroded components.
Applications & Industries
Heft Engineers’ Air Cooled Heat Exchangers find application in many sectors where efficient cooling is critical. Typical industries include:
Oil & Gas :(upstream, midstream, downstream): Cooling of condensate, natural gas, refinery process fluids.
Petrochemicals & Chemicals: Heat recovery, cooling of reaction fluids, process‐stream cooling.
Power Generation : Cooling of turbine oil, lubricants, ambient air after compressors, auxiliary systems.
• Manufacturing & Heavy Industries :Metal processing, pulp & paper, cement plants, sugar mills, etc., where hot process fluids must be cooled reliably.
• Pharmaceuticals & Food Processing :Where hygiene, precise temperature control, and cleanliness are important, and water usage is restricted.
• Mining & Material Processing :Cooling fluids in mineral extraction, wash systems, ore crushing and grinding where reliable cooling without water losses is an advantage.
