Commercial Buildings
Central HVAC for malls, hotels, offices and showrooms: chillers, AHUs, VRF, BMS and fire systems that keep tenants comfortable and bills predictable.
InterContinental Dhaka, Eastern Plus and Fortune Shopping Centre depend on MHM for central plant that runs quietly behind the scenes. Commercial buildings need part-load efficiency — the plant runs at 40–60% load most hours — low noise near guest rooms, and a BMS that lets one operator run the building.
We deliver chillers and towers, AHUs and FCUs, VRF where floors are let separately, ducting, fire hydrant and sprinkler systems, lifts and BMS integration, with service crews used to working around guests and shoppers.
The engineering problems in commercial buildings
Efficiency at part load
Multiple smaller chillers, VFD pumps and tower fans, and chilled-water reset for the 40–60% load that dominates the year.
Comfort and indoor air
AHUs with fresh-air control, CO₂ demand ventilation and low-noise fans near occupied areas.
One operator, one screen
BMS with schedules, alarms and energy dashboards; tenant sub-metering where floors are let.
Life safety
Fire hydrant, sprinkler and smoke-control systems integrated with the HVAC shutdown sequence.
How we solve them
- 1
Central chilled-water plant
Water-cooled screw chillers with towers for large buildings; air-cooled or VRF for smaller ones.
- 2
Air side
AHUs, FCUs, ducting, ventilation and kitchen exhaust.
- 3
Building management
Siemens Desigo or KMC BACnet BMS with energy reporting.
- 4
Fire protection & lifts
Hydrant and sprinkler systems, fire pumps, passenger and service lifts.
Services specified for commercial buildings
HVAC
AHU, FCU, VRF and ducted-split systems for factories, hospitals and offices.
Chillers
MHM-manufactured and imported chillers — air cooled and water cooled, 5–850 TR.
Cooling Towers
MHM-manufactured FRP cooling towers and imported towers — supplied, erected and rebuilt by one team.
Solar System
On-grid, off-grid and hybrid solar systems for factory roofs and sites.
Fire Detection & Protection
Addressable fire detection and alarm, plus hydrant, sprinkler and suppression systems.
Water Treatment Plants & Chemicals
RO, DM, softener and effluent treatment plants, plus treatment chemicals for cooling towers, chillers and boilers.
Power & Electrical
Generators, transformers, UPS and battery banks, switchgear, distribution panels and voltage stabilizers.
Commercial Buildings plants running MHM equipment
Common questions from commercial buildings plants
Chilled water wins above roughly 150 TR or where a single owner pays the bill; VRF suits multi-tenant floors and phased fit-outs. Many buildings use both — we design the split.
Yes. Service and repair work in hotels and malls is scheduled at night with quiet-work rules and a named site lead.
Industries we serve
Textile & Garments
Dyeing, finishing, spinning and garment plants: process chilled water for jet dyeing, humidification for spinning, comfort cooling for sewing floors.
Pharmaceuticals
GMP HVAC with validated temperature, humidity and pressure control, purified-water plants and documented service records for audit day.
Steel & Re-rolling
Induction-furnace and mill cooling: closed-loop soft-water circuits, high-capacity cooling towers, plate heat exchangers and pumps that run three shifts.
Food & Beverage
Hygienic process cooling, cold rooms and ice-water systems for edible oil, dairy, beverage, bakery, poultry and seafood plants.
Plastics & Packaging
Mould and extruder cooling, compressed air and clean power for injection moulding, PET, film, pipe and packaging plants.
Hospitals
Operating-theatre and ward HVAC with pressure control, redundancy and 24-hour support — because a hospital plant is never allowed to stop.
Data Centres & Telecom
Precision cooling with concurrent maintainability, free-cooling economisers and monitored power for server rooms, exchanges and towers.
Energy, Gas & CNG
Compressor cooling, LPG and SNG systems, fire protection and standby power for CNG stations, LPG and oil terminals, battery and power plants.
Government & Institutional
Public buildings, defence workshops and institutions: tendered HVAC and utility works delivered to PWD specifications with full documentation.
