Industrial cooling and ventilation in Chittagong
Chittagong is the port through which almost all Bangladeshi trade moves, and its industry sits close to the water. The Chittagong and Karnaphuli export processing zones hold garment, knit and accessory factories; Kalurghat, Nasirabad and Sagorika carry steel re rolling, cement grinding, edible oil refining and CI sheet works; and the Sitakunda coast north of the city is lined with ship breaking yards and the re rolling mills they feed. The Mirsharai economic zone is adding new capacity along the Dhaka highway. Sea air here is heavy with moisture in every month, so mills fight heat with volume of air rather than with cooling. Hammer exhaust fans on gable walls together with HVLS fans over the floor are the combination that actually suits Chittagong buildings.
Chittagong climate — the honest version
Chittagong sits on the coast and stays humid all year, with sea air close to saturation through the long monsoon, so evaporative cooling is not a sound choice and the need is volume of air and reliable extraction.
Chittagong is the arrival port itself, roughly 7 to 12 days sailing from Nhava Sheva or Mundra, which makes it the shortest lead time of any of our South Asian export destinations.

- Readymade garments and accessories
- Ship breaking and steel re rolling
- Cement grinding and CI sheet
- Edible oil and food processing
- Fisheries and frozen food
- Port logistics and warehousing
Worth knowing locally
- Industrial mains runs at 400 to 415 V three phase 50 Hz, and voltage dips are common, so a VFD driven PMSM fan is a safer choice than a fixed speed induction unit.
- Re rolling mills and CI sheet works generate radiant heat that no cooler can address; here the specification is large Hammer wall fans, up to 1750 mm and 68,000 CMH, working with roof level extraction.
- Coastal salt air attacks fasteners and blade fixings, so protected hardware and a scheduled inspection of blade bolts are worth building into the maintenance plan.

Ask on WhatsAppHow quickly can equipment reach Chittagong from India?
Production takes 10 to 20 working days, and the sea leg from Nhava Sheva or Mundra to Chittagong is only 7 to 12 days. With clearance, most Chittagong buyers have equipment on site within five to seven weeks of order confirmation, which is the fastest of our export lanes.
What ventilation suits a steel re rolling mill in Kalurghat?
Radiant heat from furnaces and rolled stock cannot be cooled away, so the aim is to move heat out fast. Large Hammer wall exhaust fans up to 1750 mm and 68,000 CMH placed opposite fresh air openings, with HVLS fans over the operator zones, give a workable temperature gradient across the mill.
Can mobile fans be used in Chittagong ship breaking and repair yards?
Yes, and they suit that work well. The 1.5 m mobile industrial fan moves 38,000 CMH on 370 W and can be repositioned as cutting moves along a hull section. For enclosed spaces it should be paired with proper extraction rather than used on its own, since a fan alone does not remove fume.
