Industrial Water Cooled Chiller Price in Bangladesh
A water cooled chiller rejects its heat into condenser water and needs a cooling tower, a condenser pump and a water treatment programme — which is why its price has to be read as a plant, not a single machine. In exchange it condenses at a lower temperature and draws less power per TR, so it is the normal choice above roughly 100 TR and on any load that runs two or three shifts. MHM Machineries BD Ltd supplies water cooled chillers from 1.5 TR to 200 TR with the tower, pumps, piping and treatment in the same scope.
- Water cooled MCH machines up to 200 TR (703 kW of cooling)
- 0.88 kW per TR at 100 TR on MHM’s sheet — rating condition not stated, so ask
- Tower selected on kW of heat rejection, not on the chiller’s TR number
- Chiller, tower, pumps, piping and treatment quoted line by line

What you are actually buying: the plant, not the box
A water cooled chiller quotation that shows only the machine is incomplete. These six items are what make the water cooled route work — and what an honest comparison against an air cooled machine has to include.
The chiller
Compressor, condenser (shell-and-tube on the condenser-water side), expansion valve and evaporator in one packaged machine, installed in a plant room rather than outdoors.
The cooling tower
Rejects the condenser heat by evaporation. Selected on kilowatts of heat rejection rather than by copying the chiller’s TR number, because a tower TR is a nominal rating that already carries the compressor heat.
Condenser and chilled-water pumps
Two circuits, two pumps. Condenser water moves roughly 0.7 m³/h per chiller TR (3 US gpm/ton); the chilled-water pump follows the flow column of the chiller table.
Piping, insulation and valves
Chilled water insulated to stop condensation and gain, condenser water usually bare, both with strainers, balancing valves and pressure gauges at the points you will actually need a reading.
Water treatment
A dosing and blowdown programme for the open tower circuit, plus a softener where the make-up water is hard. Skipping this is what turns a new condenser into a scaled one inside a year.
Heat exchanger, where the loops must stay apart
Induction furnaces, laser cutters and anything needing low-conductivity water run a closed loop separated from the tower circuit by a plate or shell-and-tube exchanger.
How an industrial water cooled chiller works
Four components and one refrigerant loop. The compressor raises the refrigerant’s pressure and temperature. In the condenser the refrigerant gives that heat to the condenser water and turns liquid — and it is the cooling tower, not the chiller, that then throws the heat away. Through the expansion valve the liquid drops in pressure and temperature, and in the evaporator it absorbs heat from your process water and becomes gas again. The cycle repeats, continuously, for as long as the load is there.
The practical point for a plant engineer: the machine can only be as cold as its condenser lets it be. Condenser water two degrees warmer than design, or a condenser tube coated with scale, shows up immediately as lost capacity and a higher kW per TR — which is why tower performance and water chemistry are part of chiller performance, not separate topics.
- Compressor — raises pressure and temperature
- Condenser — hands heat to the condenser water
- Expansion valve — drops pressure, drops temperature
- Evaporator — takes heat out of your process water
What sets the price of a water cooled chiller
Swipe the table sideways to see every column.
| Cost driver | Why it changes the price | Effect |
|---|---|---|
| Capacity (TR) | Compressor, shell-and-tube condenser, evaporator and panel scale together. | Largest single driver |
| Compressor type | Scroll or reciprocating on the smaller duties, screw above roughly 60–80 TR. | Often the biggest line in the bill of materials |
| Tower, pump and treatment | A water cooled machine cannot run without them, so they belong in the comparison. | Adds a real capital cost that an air cooled quotation does not carry |
| Condenser material | Copper is the usual tube material; MHM lists copper, copper-nickel and stainless steel as options, so confirm which one your quotation covers. | A clear premium, and the right answer on brackish or ETP-affected water |
| Imported complete or locally assembled | Freight, LC and duty against 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 |
| Plant room and civil work | Foundation, drainage, ventilation for the plant room, and the tower base on the roof or yard. | Usually a separate civil line, not in the equipment price |
| Redundancy | Two machines where the load needs one and a half, or a standby pump on a critical circuit. | Chosen deliberately in pharma, food and furnace plants |
MHM quotes against your duty. The quotation states the model, the capacity in TR and kW, the total power input, and the tower, pumps, piping, treatment and installation as separate lines — so the water cooled and air cooled options can be compared on the same basis instead of on the machine price alone.
Read kW per TR, then read it again in month three
Total power input divided by capacity in TR is the figure to compare on. On MHM’s published MCH sheet a 100 TR machine draws 88 kW total input, which is 0.88 kW per TR. Two caveats worth stating plainly: the sheet publishes one power column for the whole range without saying which condenser arrangement or rating condition it belongs to, so ask for that in writing; and whatever the number is, it is only held on site if the condenser water arrives at design temperature and the tubes stay clean. A treatment programme and a tower in good order are part of the efficiency you paid for.
The running-cost comparison nobody writes down
Against an air cooled machine, a water cooled plant usually wins on electricity per TR — it condenses against tower water instead of hot outdoor air — and loses on water, chemicals and maintenance hours. On a two or three shift load the electricity difference dominates; on a single shift or seasonal load it often does not. Ask each supplier for kW per TR with the rating condition stated, put both quotations side by side with equal scope, add your own tariff and water cost, and the answer stops being a matter of opinion.
Ask for these lines in writing
- Chiller model, TR, kW, total power input and the condition those are rated at
- Tower model and the heat rejection it is selected for
- Condenser pump duty (m³/h and head) and chilled-water pump duty
- Piping, insulation and valve scope, with the boundary stated
- Water treatment programme and first chemical fill
- Electrical scope: starter or drive, cabling, interlocks
- Installation, commissioning and operator handover
- Warranty: compressor as against the rest of the machine, and whether site labour is included
Water cooled machines in the MHM range
The full 26-model MCH table lives on the chiller page. Shown here is the part of the range where water cooled machines are normally selected, with kW per TR worked out and the condenser water flow a tower would have to carry.
Swipe the table sideways to see every column.
| Model | Capacity (TR) | Capacity (BTU/h) | Cooling capacity (kW) | Chilled water flow (l/min) | Compressor power (kW) | Total power input (kW) | Heat to reject (kW) | Condenser water flow (m³/h) |
|---|---|---|---|---|---|---|---|---|
| MCH-40 | 40 | 480,000 | 140.7 | 404 | 32 | 40 | 173 | 28 |
| MCH-60 | 60 | 720,000 | 211.0 | 606 | 45 | 54 | 256 | 42 |
| MCH-80 | 80 | 960,000 | 281.4 | 808 | 64 | 74 | 345 | 56 |
| MCH-100 | 100 | 1,200,000 | 351.7 | 1,010 | 80 | 88 | 432 | 70 |
| MCH-120 | 120 | 1,440,000 | 422.0 | 1,212 | 96 | 105 | 518 | 84 |
| MCH-130 | 130 | 1,560,000 | 457.2 | 1,313 | 104 | 114 | 561 | 91 |
| MCH-150 | 150 | 1,800,000 | 527.5 | 1,515 | 120 | 130 | 648 | 105 |
| MCH-180 | 180 | 2,160,000 | 633.1 | 1,818 | 144 | 154 | 777 | 126 |
| MCH-200 | 200 | 2,400,000 | 703.4 | 2,020 | 160 | 170 | 863 | 140 |
Model, capacity, cooling kW, chilled-water flow, compressor power and total power input are from MHM Machineries’ Specification of Chiller (PDF). The last two columns are arithmetic rather than data-sheet figures: heat to reject is cooling kW plus compressor kW, and condenser water flow is 0.7 m³/h per TR (3 US gallons per minute per ton), the flow that carries that heat at a 5 to 5.5 °C rise. Note that the sheet publishes one power column for the whole range, does not say whether a model is rated air cooled or water cooled, and states no ambient or condenser-water condition — so use these figures to size the loop and get the rating condition confirmed in writing before comparing them with another maker’s numbers.
Water cooled or air cooled? Decide on the load, not the brochure
Swipe the table sideways to see every column.
| Situation on your site | Usually the right choice | Why |
|---|---|---|
| Load runs two or three shifts | Water cooled | The lower kW per TR is earned every running hour, so the extra scope pays back |
| Load is intermittent or seasonal | Air cooled | Tower, pump and treatment cost money whether the plant runs or not |
| Duty above roughly 100 TR | Water cooled | Screw machines on condenser water stay compact and efficient at that size |
| No space or no water for a tower | Air cooled | A tower needs free air on every face, a base, make-up water and drainage |
| Water is scarce, hard or expensive | Air cooled | Evaporation, drift and blowdown are continuous, and treatment is not optional |
| No maintenance team for water chemistry | Air cooled | An untreated tower circuit scales the condenser and the bill arrives as lost capacity |
| Plant room available, roof already loaded | Water cooled | The machine goes indoors and only the tower needs an outdoor position |
If the table points to air cooled for your case, we will say so: air cooled chiller price in Bangladesh. Selling the wrong machine costs more in service calls than it earns.
Sizing the whole loop, in five steps
- Size the chiller from the process. kW = flow (l/s) × 4.19 × temperature drop (°C); TR = kW ÷ 3.517. Add the future-load and diversity allowance before selecting.
- Read the heat to reject, in kW. Cooling kW plus compressor kW — both are published columns in MHM’s chiller sheet, and both are in the table below. An MCH-60 rejects 211.0 + 45 = 256 kW.
- Set the condenser water flow. About 0.7 m³/h per chiller TR (3 US gallons per minute per ton), which carries that heat at a 5 to 5.5 °C rise. An MCH-60 needs roughly 42 m³/h.
- Select the tower on kW, not by copying the chiller’s TR number. A tower TR is a nominal rating that already includes the compressor heat: at 0.7 m³/h per TR and a 5 °C range, one tower TR carries about 4.1 kW. 256 ÷ 4.1 ≈ 62 tower TR, so the 80 TR row is taken, and its 56 m³/h design flow comfortably covers the 42 m³/h the condenser needs. Multiplying the chiller TR by 1.2 and then reading the tower table oversizes by about a quarter.
- Check the approach, then fix the pumps and interlocks. The tower cannot deliver water colder than the wet-bulb, so check the approach against a design wet-bulb from a recognised climatic data set. Chilled-water pump from the chiller flow column; condenser pump from the flow above plus the tower head loss and the pipe and condenser losses; and an interlock so the compressor cannot run without flow on either side.
Worked example — 8 l/s dye house
8 l/s with a 5 °C drop = 8 × 4.19 × 5 = 167.6 kW = 47.7 TR. With a 10 percent allowance, about 52 TR, so an MCH-60 is selected.
That machine rejects 211.0 kW of cooling plus 45 kW of compressor = 256 kW. At about 4.1 kW per tower TR that is roughly 62 tower TR, so the 80 TR row is taken. The condenser itself needs about 60 × 0.7 = 42 m³/h, and the 80 TR tower is designed for 56 m³/h, so the loop has margin. The condenser pump is sized on the flow you settle on plus the tower head loss (25 kPa at 80 TR) and the pipe and condenser losses.
Installation, commissioning and the maintenance that protects the efficiency
Installation
Machine foundation and anti-vibration mounts; chilled-water and condenser-water piping with strainers, valves and expansion provision; insulation on the chilled side; the electrical connection with starter or variable frequency drive; and the interlocks between chiller, both pumps and the tower fan so the compressor can never run dry.
Commissioning
Flush and pressure test before the machine is opened to the loop, flow verified against the data-sheet figure, refrigerant charge, superheat and sub-cooling readings, safety and interlock tests, a pull-down under real load, and the first set of temperatures across both the evaporator and the condenser recorded on paper. Those readings are the baseline for every later argument about performance.
Maintenance that is specific to water cooled plant
- Condenser tube cleaning — brushing or chemical, on a schedule set by the water quality
- Dosing and blowdown control, with cycles of concentration checked against the make-up water
- Tower cleaning, fill and nozzle inspection, fan rotation and current draw
- Approach and range logged monthly — a drifting approach is an early warning, not a failure
- Strainer cleaning on both circuits, and pump seal and bearing checks
MHM installation, maintenance and repair services cover all of the above, including on plants MHM did not supply.

Water cooled chiller তার তাপ condenser-এর পানিতে ছাড়ে, তাই এর সাথে অবশ্যই cooling tower, condenser pump ও পানির treatment লাগে। এজন্য দাম শুধু machine-এর দাম নয় — পুরো plant-এর দাম হিসাব করতে হয়।
বিনিময়ে এটি কম তাপমাত্রায় condense করে, তাই প্রতি TR-এ বিদ্যুৎ খরচ কম। MHM-এর data sheet অনুযায়ী ১০০ TR machine-এর total input ৮৮ kW, অর্থাৎ ০.৮৮ kW per TR। সাধারণত ১০০ TR-এর বেশি duty-তে এবং দুই-তিন shift চলা load-এ water cooled নেওয়া হয়।
হিসাবটা kW-তে করতে হয়, TR-তে নয়। MCH-৬০ ঠান্ডা করে ২১১ kW, compressor ৪৫ kW — অর্থাৎ বর্জন করতে হবে ২৫৬ kW। Tower-এর প্রতি TR প্রায় ৪.১ kW সরায় (compressor-এর তাপ ওর ভেতরেই ধরা), তাই ২৫৬ ÷ ৪.১ ≈ ৬২ tower TR → ৮০ TR row। Condenser-এ পানি লাগে প্রতি chiller TR-এ প্রায় ০.৭ m³/h, অর্থাৎ ৪২ m³/h। TR-কে ১.২ গুণ করে আবার tower table দেখলে tower এক-চতুর্থাংশ বড় হয়ে যায়।
যদি কারখানায় tower বসানোর জায়গা না থাকে, পানি দুষ্প্রাপ্য বা শক্ত হয়, অথবা plant একটানা না চলে — তাহলে air cooled chiller ভালো। আমরা সেটাই বলব, কারণ ভুল machine বিক্রি করে লাভ নেই। ফোন +880 1767-004433।
Frequently asked questions
What is the price of a water cooled chiller in Bangladesh?
It is quoted per duty, and it has to be read as a plant price. The machine itself moves with capacity in TR, compressor type and brand, condenser material and whether the unit is imported complete or locally assembled; on top of that a water cooled selection always carries a cooling tower, a condenser pump and a water treatment programme. MHM states each of those as a separate line so the total can be compared against an air cooled quotation honestly. Send the process, the heat load and the water temperature you must hold for a written quotation.
Is a water cooled chiller cheaper to run than an air cooled one?
Usually yes on electricity, because it condenses against tower water rather than hot ambient air, and on the same duty that shows up as a lower kW per TR. It is not cheaper on water, chemicals or maintenance hours. On a load that runs two or three shifts the electricity saving normally dominates; on a single-shift or seasonal load it often does not. One caution when you compare: MHM’s sheet publishes a single power column for the whole MCH range and does not split it by condenser type, so ask each supplier for kW per TR with the rating condition stated, then add your own tariff, water cost and maintenance time.
What size cooling tower does a water cooled chiller need?
Work in kilowatts. An MHM MCH-100 is 351.7 kW of cooling with an 80 kW compressor, so it rejects 431.7 kW, and the condenser itself needs about 0.7 m³/h per chiller TR — 3 US gallons per minute per ton — which is roughly 70 m³/h. A tower TR is a nominal rating that already includes the compressor heat, about 4.1 kW per TR at that flow and a 5 °C range, so 431.7 kW is about 105 tower TR and the 125 TR row is the selection. Multiplying the chiller TR by 1.2 and then reading the tower table counts the compressor heat twice. MHM’s published FRP bottle-type range runs 10 TR to 500 TR.
How many TR of water cooled chiller do I need?
Size from the process, not the floor area: load in kW equals water flow in litres per second × 4.19 × the temperature drop in degrees Celsius, and TR equals kW divided by 3.517. For example, 8 l/s cooled by 5 °C is 167.6 kW or 47.7 TR; with a 10 percent allowance that is about 52 TR, so a 60 TR machine is selected and the tower is then sized for about 72 TR of heat rejection.
What maintenance does a water cooled chiller need?
Everything an air cooled machine needs, plus the water side: condenser tube cleaning on a schedule set by your water quality, a dosing and blowdown programme with cycles of concentration checked against the make-up water, tower cleaning with fill and nozzle inspection, fan rotation and current draw, strainer cleaning on both circuits, and a monthly log of range and approach. A drifting approach is an early warning; a scaled condenser is the bill that follows if it is ignored.
Can a water cooled chiller be installed on the roof?
The machine normally goes in a plant room and only the cooling tower stands outdoors, which is one of the reasons the water cooled route is chosen where roof space is already committed or where noise at the boundary matters. What the tower does need is free air on every face and clearance from walls and neighbouring structures, or the hot plume recirculates into the intake and the approach collapses.
What capacity of water cooled chiller does MHM supply?
The published MCH range runs from 1.5 TR to 200 TR (2,400,000 BTU/h, 703 kW, 2,020 l/min chilled water, 170 kW total power input), on R22 / R407c, in air cooled and water cooled configurations, with scroll, reciprocating and screw compressors from Carrier, Bitzer, Danfoss and Daikin or equivalent. Larger duties are met by running machines in parallel on a common chilled-water header.
