Ventilation in Bangladesh.

Your factory is hot and you already have enough tonnage. The problem is usually not cooling — it is that hot air has nowhere to go.

Buying more chiller to fix a ventilation problem is the most expensive possible answer.

RMG machinery and lighting generate heat. Source extraction and engineered make-up air reduce the load on factory cooling systems.

Extracting heat where it is produced often delivers more felt relief per taka than any chiller, and costs a fraction to run. We will tell you this at the load audit even though it sells less equipment.

FABRICATION & INSTALL

Ductwork we fabricate ourselves.

Ventilation stands or falls on the ductwork. We fabricate GI and stainless ducting in our own workshop and install it with our own crews — the same capability behind our Sri Lanka and Maldives ventilation work.

What we design and install.

Heat extraction — roof and wall-mounted extract engineered against the actual heat gain, not a rule of thumb.
Engineered make-up air — filtered, tempered where needed. Extract without make-up just starves the floor.
Lint management — filtration and coil protection for textile and washing plants, where lint destroys efficiency.
Kitchen and canteen exhaust — hoods, ducting and ecology units for large staff canteens.
HVLS fans — large-diameter low-speed fans for high, open production spans.
Plant-room and generator-room ventilation — BNBC-compliant, and sized for the heat the plant actually rejects.

Compliance depends on it too.

Workplace temperature, air quality and ventilation rates sit inside buyer and RSC compliance. A floor that fails on air change rate is a commercial finding against the factory, and ventilation is usually the cheapest route to closing it.

Common questions

What Bangladeshi buyers ask us first.

How do we know whether we need cooling or ventilation?

A load audit. We measure the actual heat load, the air movement you have now and the electrical capacity available, on site, at your busiest hour. Often the answer is ventilation first, and less cooling than expected.

Will ventilation alone make an RMG floor comfortable?

Sometimes, and often it gets you most of the way. Where humidity affects the process or the product, dehumidification joins it. Where the ambient is simply too high, ventilation reduces the cooling you then have to buy.

Can this be retrofitted into a running factory?

Yes. Most of our ventilation work is retrofit, phased around production so the floor keeps running.
