Robust heat transfer equipment withstands harsh conditions when its duty, materials, airflow, support and maintenance access are designed around the real site. Extran designs, manufactures, supplies, services and maintains industrial heat transfer equipment, with...
Skid-mounted heating and cooling systems meet pipe code requirements when the applicable code, design conditions, materials, joints, supports, inspection points and test boundaries are defined before fabrication. The skid layout then has to turn those requirements...
A total process skid package moves from conceptual design to commissioning by fixing the process duty first, defining every interface, arranging equipment for operation and maintenance, then testing the agreed package before it reaches the site. The skid is not simply...
Co generation heat exchangers recover useful energy from engine exhaust by transferring heat into a defined plant duty without exceeding the engine maker’s back-pressure limit. A workable design starts with the heat user, then sets the temperature approach, materials,...
Closed loop cooling systems reduce plant-wide water use by recirculating a controlled cooling fluid instead of continually drawing and discharging fresh water at the process boundary. They can also isolate process equipment from variable water quality. The practical...
Workshop rebuilding and retubing an industrial lube oil cooler is a controlled sequence of inspection, cleaning, failure assessment, tube or component repair, reassembly and testing. The aim is to restore the required duty without carrying a hidden leak, contamination...
On site equipment audits identify heat exchanger performance issues by comparing the unit’s current duty with temperatures, flow conditions, pressure behaviour, airflow, mechanical condition and operating history. That evidence helps a plant distinguish fouling from...
Repairing industrial radiators and oil coolers to AS1210 or ASME VIII starts by identifying the pressure-containing boundary and confirming whether either standard is actually nominated for the equipment. Not every radiator or cooler falls under the same code. The...
Testing pressure equipment with a calibrated gauge means matching the instrument to the test range, confirming its calibration status, controlling the test boundary and recording the result against the approved procedure. The gauge reading is only useful when the...
A manufacturer data record, or MDR, turns the production history of industrial heat-transfer equipment into a controlled, usable record. It connects the agreed duty and design basis with drawings, materials, inspections, tests, changes and final release information....
A fin fan unit can look acceptable through mild weather and then fall short during a hot spell. High ambient thermal derating explains that loss of margin. It helps the site understand whether weak performance is caused by weather, fouling, airflow, control settings...
Air cooler fan components are often sourced quickly during outages, but the part number is only the starting point. Blade replacement affects airflow, balance, noise, vibration and motor load. Hubs, blades and bearings need to be checked as a working system. Extran...
Fan diameter is only one part of an industrial cooling decision. Large diameter industrial fans need to be specified with duty, hub design, blade profile, speed, motor load, noise and access in mind. The same discipline applies to smaller packaged fan units. This...
Radiator rebuilds depend on tube selection more than many shutdown plans admit. A finned replacement tube may restore a known geometry, but the tube still has to match duty, material, airflow and service condition. The wrong replacement can fit neatly and still leave...
Australian industrial sites rely on practical engineering judgement when fan system retrofit and acoustic attenuation affect uptime, safety and operating cost. The discussion below keeps the focus on evidence, modelling where it is useful, and workshop decisions that...
Australian industrial sites rely on practical engineering judgement when alloy plate selection and harsh fluid cooling affect uptime, safety and operating cost. The discussion below keeps the focus on evidence, modelling where it is useful, and workshop decisions that...
Australian industrial sites rely on practical engineering judgement when compact unit flushing and alternative clean in place methods affect uptime, safety and operating cost. The discussion below keeps the focus on evidence, modelling where it is useful, and workshop...
Copper brazed compact units are efficient because thin plates are permanently joined into a sealed core. That construction can reduce the need for gasket maintenance and save space, but it also means the unit must be matched to suitable service conditions. Understand...
Spare PHE plates and gaskets look simple until a shutdown depends on them. Correct sourcing requires model identification, material compatibility, port arrangement, gasket compound, and frame capacity checks before the unit is opened. Start With Identification Before...
Gasketed plate units respond quickly to changes in duty because their passages are compact and highly efficient. Adjusting surface area can be effective, but plate pack tightening must stay within frame, gasket, and plate limits. Confirm Whether Surface Area Or...
Boiler feed water heaters must lift temperature while protecting a high pressure boundary. The design task is not only to transfer heat. It must also manage water chemistry, tube velocity, expansion, testing, and safe isolation during maintenance. Define The Feed...
Single phase and dual phase duties behave differently inside heat transfer equipment. A liquid cooler with stable properties can often be predicted with a narrower model. Condensing, boiling, or flashing services need a deeper review because pressure, vapour quality,...
Shell thickness is a safety boundary, a corrosion allowance, and a service-life decision. It cannot be selected from pressure alone. Mechanical calculations determine whether the exchanger shell can contain duty conditions, withstand local loads, and remain...
Selecting a fixed tubesheet heat exchanger configuration involves more than choosing a combination of TEMA letters. The front head, shell and rear head arrangement can affect tube-side access, cleaning options, thermal expansion, pressure-drop considerations and how...
Industrial coolers do not always operate under the same conditions as when they were originally designed. Changes in process flow, fluid properties, ambient temperature, fouling, control settings or production requirements can alter the heat duty and available...
Hydraulic systems generate heat at almost every working component. Pump inefficiency converts a portion of the input energy to heat. Pressure drops across valves convert pressure energy to heat. Friction in cylinders and motors generates heat. Internal leakage in worn...
Building a thermal process system in place at a plant site is expensive, slow, and exposed to weather, access, and trade-coordination risks that compound the longer the work takes. Every interface between separately specified components (heat exchanger to pump, pump...
A radiator that performs reliably in an automotive application or a domestic HVAC system can fail within weeks if pressed into heavy-duty industrial service. The reason is not poor manufacturing or unusual circumstances. It is that standard radiators are designed for...
Mine sites place demands on cooling equipment that few other industrial environments match. Continuous dust loading, high ambient temperatures across the Australian summer, distance from urban support infrastructure, and the production cost of any unplanned outage all...
Heat is generated at almost every stage of an oil and gas processing facility. Crude separation, gas compression, distillation, dehydration, and product storage all release thermal energy that must be removed, recovered, or transferred for the process to operate...
