Industrial Air Cooled Chiller Price in Bangladesh
An air cooled chiller rejects its heat straight to ambient air through a finned condenser, so it needs no cooling tower, no condenser pump and no water treatment, and it can stand outdoors or on the roof. That is why it is the usual choice up to about 100 TR and on any load that does not run continuously. MHM Machineries BD Ltd supplies air cooled chillers from 1.5 TR to 200 TR — imported complete or locally assembled — with installation, spares and service from Mirpur, Dhaka.
- No cooling tower, no condenser pump, no water chemistry
- Installed outdoors or on the roof — no plant room needed
- MCH range 1.5–200 TR; air cooled is most often supplied up to about 100 TR
- Scroll, reciprocating and screw compressors, imported or locally assembled

Why factories in Bangladesh choose air cooled
These are the six reasons an air cooled machine wins a comparison — and they are all about what is not in the scope.
| Advantage | What it means on site |
|---|---|
| Lower installed cost | No tower, no condenser pump, no treatment programme and no plant room in the scope. |
| Quicker availability | Fewer items to procure and install, so a smaller machine can be running in weeks rather than months. |
| No water consumption | Nothing evaporates, nothing is blown down, and there is no make-up water line to run to the roof. |
| No water chemistry to manage | No dosing, no blowdown, no cycles of concentration, no condenser tube cleaning — the maintenance is a coil and a set of fans. |
| No plant room required | The machine lives outdoors or on the roof, which frees the floor space a plant room would have taken. |
| Simpler to move later | A packaged outdoor unit can be relocated with the process it serves. A tower, a basin and two pump circuits cannot. |
And the honest trade-off
An air cooled machine condenses against outdoor air, and outdoor air in Dhaka is hot. That means a higher condensing temperature and more kW per TR than a water cooled machine on the same duty, and it means the capacity you actually get depends on the ambient temperature and on how freely the condenser can breathe.
On a single-shift or seasonal load that costs little, because the machine is not running most of the year. On a three-shift load at high capacity the electricity difference adds up, which is where the water cooled route earns its extra scope: water cooled chiller price in Bangladesh.
The question to ask every supplier
“At what ambient temperature is this capacity quoted?”
Air cooled capacity falls as the ambient rises. A machine rated at a mild ambient will look cheaper per TR and then fail to hold temperature on an April afternoon. Get the rating ambient, the capacity at it, and the total power input at it, in writing — for every quotation you are comparing.
Getting the installation right — five site rules
- Give the condenser its air. Leave the clearance the maker states around the coil and above the fans. Air that has just left the condenser must not be able to turn round and re-enter it — recirculation raises the condensing temperature and the machine loses capacity even though nothing has failed.
- Mind the walls and the neighbours. A unit boxed into a shaft or a walled corner behaves like a unit in a hot room. If the position cannot be changed, discharge ducts or a raised plinth are the fix, and both belong in the quotation.
- Ask which ambient the capacity is quoted at. Every air cooled machine is rated at a stated ambient temperature, and the capacity falls as the ambient rises. A capacity quoted at 35 °C and one quoted at 45 °C are not the same machine — in this climate it is the single most useful question a buyer can ask.
- Plan for lint, dust and salt. In dye houses, spinning mills and anywhere near a boiler yard the fins load up with lint and dust; near the coast the fins corrode. Coated coils and an agreed cleaning interval cost less than the lost capacity they prevent.
- Put the noise where it belongs. Condenser fans run whenever the machine runs. Keep them away from offices, boundary walls and residential neighbours, and allow for anti-vibration mounts on a roof slab.
What sets the price of an air cooled chiller
Swipe the table sideways to see every column.
| Cost driver | Why it changes the price | Effect |
|---|---|---|
| Capacity (TR) | Compressor, condenser coil, fans, evaporator and panel all scale together. | Largest single driver |
| Compressor type and make | Scroll on the smaller duties, reciprocating and screw as the size grows; Carrier, Bitzer, Danfoss, Daikin or equivalent. | Frequently the largest line below 50 TR |
| Condenser coil size and coating | A larger coil holds capacity at a high ambient; a coating protects the fins in lint, chemical or coastal air. | A real premium that buys capacity on the hottest afternoons |
| Fan arrangement | Number of fans, blade material, and whether fan speed is controlled. | Affects noise, part-load power and the condensing temperature |
| Evaporator type | Shell-and-tube or plate. Plate is compact; shell-and-tube tolerates dirtier water. | Moderate on price, decisive on behaviour with your water |
| Imported complete or locally assembled | A complete imported unit carries freight, LC and duty; a locally assembled unit has a shorter lead time and easier spares. | Moves with the exchange rate and duty on the day |
| Controls | Contactor panel, PLC, or a variable frequency drive on the compressor. | Adds capital cost, repays it at part load |
| Pump set and buffer tank | An air cooled machine still needs a chilled-water pump, and usually a buffer tank where the load swings. | Quoted as a separate line, and often forgotten in a comparison |
| Installation scope | Base or plinth, anti-vibration mounts, piping, insulation, cabling, starter, commissioning. | Ask for the split — equipment against installation |
MHM quotes against your duty rather than publishing a list price, because the compressor brand, the exchange rate and the duty on the day of the LC all move the figure. The quotation states the model, the capacity in TR and kW, the total power input, and equipment against installation as separate lines.
The MCH sizes usually supplied as air cooled units
The full 26-model table is on the chiller page. This excerpt covers the 1.5 TR to 100 TR band with kW per TR worked out, so two quotations can be compared on electricity and not just on price.

Model, capacity, flow and total power input are from MHM Machineries’ Specification of Chiller (PDF); kW per TR is total power input divided by capacity, worked out here rather than published. Three things to know before you use that column: the sheet publishes one power column for the whole range and does not separate air cooled from water cooled ratings; it states no ambient, condenser-water or chilled-water condition; and the implied efficiency is not smooth — 1.50 kW per TR at MCH-02 and 1.43 at MCH-7.5 against 0.88 at MCH-100. The MCH-7.5 figure is tied to a naming quirk: that model is rated 84,000 BTU/h, which is 7.0 TR rather than 7.5. Every row of the 1.5–100 TR band is shown above, in the sheet’s own order, so nothing flattering has been selected; the 120–200 TR rows are on the chiller page.
Where air cooled chillers are working in Bangladesh
Plastics and moulding
Mould and barrel water at a stable set point, on loads that start and stop with the shift. An outdoor packaged unit beside the shed is the usual answer, with the loop controlled to a set point rather than run as cold as the machine can go — below the dew point the tool sweats in Dhaka’s humidity.
Food, beverage and bakery
Dough water, filling lines, pasteuriser sections and cold-room glycol duty — a glycol loop below zero is a different selection from a plain water chiller and de-rates the machine, so it has to be stated on the enquiry. Hygiene rules make an air cooled machine attractive here, because there is no tower plume and no open water circuit anywhere near the product.
Pharma and cleanroom AHUs
Chilled water for the cooling coils that hold cleanroom temperature and humidity in a validated band. Redundancy is normal here — two smaller air cooled machines instead of one large one, so a service visit does not shut the suite.
Textile and general manufacturing
Smaller dye houses, garment finishing, compressor after-coolers and machine cooling, where a tower would need water, a base and a maintenance team that a compact site does not have. Coil cleaning matters here more than anywhere else, because of the lint.
Maintenance: it is a coil and a set of fans
The whole maintenance case for air cooled plant is that there is no water circuit to look after. What replaces it is one discipline — keeping the condenser coil clean. A coil blanketed in lint behaves exactly like a hot day: condensing temperature climbs, power per TR climbs with it, and on the worst afternoon the machine trips on high pressure and the process stops.
Log the ambient, the condensing temperature and the kW drawn once a month on the same sheet. A coil that is fouling shows up in those three numbers weeks before it shows up as a trip.
- Condenser coil cleaning on an interval set by how dirty the air is — monthly in a lint-heavy mill, quarterly in a clean plant
- Fan motor and blade checks, including direction of rotation after any motor change
- Refrigerant charge, superheat and sub-cooling readings, and a look at the high-pressure trip history
- Chilled-water side: strainer cleaning, flow verification, glycol concentration where glycol is used
- Electrical tightening, contactor wear, and control calibration
- A monthly log of ambient, condensing temperature and kW drawn — the earliest warning of a dirty coil
MHM installation, maintenance and repair services cover coil cleaning, refrigerant work, electrical checks and repairs — including on machines MHM did not supply.
How to size an air cooled chiller
- Work out the load. kW = flow (l/s) × 4.19 × temperature drop (°C). Then TR = kW ÷ 3.517.
- Add the allowance. Future load and diversity between machines, then take the next MCH model up — never the one below.
- State the ambient and the water temperature. The rating ambient decides the real capacity, and a supply temperature below about 5 °C means glycol and a de-rated machine.
- Size the pump and the buffer. Chilled-water pump from the flow column of the table; a buffer tank where the load swings, so the compressor is not short-cycled.
- Check the position before you order. Free air on the coil faces, clearance above the fans, a level base, and a cable route that does not cross the discharge air.
Worked example — an injection moulding shop
Six machines circulating 4 l/s of mould water with a 5 °C rise: 4 × 4.19 × 5 = 83.8 kW = 23.8 TR. With a 15 percent allowance for a seventh machine, about 27 TR — so an MCH-30 is selected, with a buffer tank because the moulding load pulses with every shot.
Not sure the air cooled route is right? The comparison table on the chiller hub page sets air cooled against water cooled line by line, and we will say plainly if your load points the other way.

সংক্ষেপে — বাংলায়
Air cooled chiller তার তাপ সরাসরি বাতাসে ছাড়ে finned condenser দিয়ে। তাই cooling tower, condenser pump বা পানির treatment — কিছুই লাগে না, machine ছাদে বা বাইরে বসানো যায়, আর আলাদা plant room দরকার হয় না। এজন্য প্রায় ১০০ TR পর্যন্ত এবং যেসব load একটানা চলে না, সেখানে এটাই স্বাভাবিক পছন্দ।
তবে সৎ কথাটা হলো — বাইরের বাতাস গরম হলে air cooled machine-এর capacity কমে যায় এবং প্রতি TR-এ বিদ্যুৎ বেশি লাগে। তাই quotation নেওয়ার সময় অবশ্যই জিজ্ঞেস করুন: “এই capacity কত °C ambient-এ দেওয়া?” ৩৫ °C-এ দেওয়া capacity আর ৪৫ °C-এ দেওয়া capacity এক জিনিস নয়।
বসানোর সময় তিনটি বিষয় সবচেয়ে জরুরি — condenser-এর চারপাশে ও উপরে খোলা বাতাস রাখা, গরম বাতাস যেন ঘুরে আবার ভেতরে না ঢোকে তা নিশ্চিত করা, এবং coil পরিষ্কার রাখা। Dye house বা spinning mill-এ লিন্টে coil বন্ধ হয়ে গেলে condensing temperature বাড়ে, বিদ্যুৎ খরচ বাড়ে, আর গরমের দিনে high pressure-এ machine trip করে।
নিজের TR হিসাব: kW = প্রবাহ (l/s) × ৪.১৯ × তাপমাত্রার পার্থক্য (°C), তারপর kW ÷ ৩.৫১৭। উদাহরণ: ৪ l/s mould water ৫ °C ঠান্ডা করলে ৮৩.৮ kW বা প্রায় ২৩.৮ TR — allowance দিয়ে MCH-৩০। ফোন +880 1767-004433।
Frequently asked questions
What is the price of an air cooled chiller in Bangladesh?
It is quoted against your duty, because capacity in TR, compressor type and brand, the size and coating of the condenser coil, the fan arrangement, the controls and whether the unit is imported complete or locally assembled all move the figure. An air cooled quotation is shorter than a water cooled one — there is no tower, condenser pump or treatment programme in it — but it still needs the chilled-water pump, buffer tank, piping and installation shown as separate lines. Send the process, the heat load and the water temperature you must hold for a written quotation.
Is an air cooled chiller cheaper than a water cooled one?
Cheaper to install, almost always, because the tower, the condenser pump, the treatment programme and the plant room are not in the scope. Not necessarily cheaper to run: an air cooled machine condenses against hot outdoor air, so it uses more kW per TR than a water cooled machine on the same duty. On a single-shift or seasonal load the installed saving usually wins; on a continuous high load the electricity difference usually wins.
Does air cooled chiller capacity fall in hot weather?
Yes. The condenser rejects heat to ambient air, so as the ambient temperature rises the condensing temperature rises with it, capacity falls and power per TR increases. That is why the rating ambient matters: ask what ambient the quoted capacity and total power input are stated at, and make sure it is realistic for your site in April and May, not a mild laboratory figure.
How much clearance does an air cooled chiller need?
Enough for the condenser to take in fresh air on its coil faces and discharge freely above the fans, to the clearance the manufacturer states for that model. The failure to avoid is recirculation — discharge air turning round and re-entering the coil, which happens when a unit is boxed into a walled corner or a shaft. Where the position cannot be changed, a raised plinth or discharge ducting is the fix, and it belongs in the quotation.
What maintenance does an air cooled chiller need?
Condenser coil cleaning on an interval set by how dirty the air is — monthly in a lint-heavy mill, quarterly in a clean plant — plus fan motor checks, refrigerant charge with superheat and sub-cooling readings, chilled-water strainer cleaning and flow verification, electrical tightening and control calibration. Log the ambient, the condensing temperature and the kW drawn monthly: a fouling coil shows up in those numbers weeks before it trips the machine.
Can an air cooled chiller be installed on the roof?
Yes, and that is the normal position in Bangladesh because it keeps the machine out of the production area and away from the boundary wall. What the roof has to give is a level base able to carry the operating weight, anti-vibration mounts, free air on the coil faces and above the fans, and a cable route that does not cross the discharge air. Noise at the parapet should be checked if there are offices or neighbours nearby.
What air cooled chiller capacity does MHM supply?
The published MCH range runs from 1.5 TR (18,000 BTU/h, 15 l/min chilled water, 2 kW total power input) to 200 TR, in 26 sizes, on R22 / R407c, with scroll, reciprocating and screw compressors. Air cooled units are most often supplied up to about 100 TR (1,200,000 BTU/h, 1,010 l/min, 88 kW total input); above that the water cooled route is usually chosen. Units are imported complete or locally assembled and customised.
