Complete HVAC Solutions — Design to Maintenance
Cooltech Corporation handles every stage of your HVAC project: load calculation, system design, equipment supply, installation, commissioning, and long-term maintenance — all under one roof, nationwide.
What we do, from start to finish
Equipment Supply & Procurement
Cooltech is the authorised supplier of internationally certified HVAC equipment in Bangladesh. Our catalogue covers the full spectrum — from 1-tonne residential split ACs to 2,000-tonne industrial centrifugal chillers. All units are AHRI-certified, ETL-certified, and compliant with ASHRAE 90.1.
- Industrial chillers (air-cooled and water-cooled, 10–2,000 tonnes)
- VRF/VRV multi-zone systems for commercial buildings
- Residential and commercial split, cassette, and ceiling-concealed ACs
- Air handling units (AHUs), fan coil units (FCUs)
- Cooling towers and associated plant-room equipment
- Precision air conditioning for data centres and server rooms
System Design & Load Calculation
Our certified engineers conduct full HVAC load calculations based on your building's specifications, occupancy, climate data, and operational requirements before recommending any equipment — ensuring you never over-specify or under-specify your system.
- Heat load calculation per ASHRAE standards
- Duct design and airflow modelling
- Chilled-water plant-room layout design
- Electrical and power requirement planning
- Energy performance projections and ROI analysis
Installation & Civil Works
Our installation teams — certified HVAC engineers supported by trained technicians — manage the complete installation process. For large industrial projects, we co-ordinate all civil, mechanical, and electrical works from a single project-management interface.
- Residential split AC and multi-head installation
- VRF indoor and outdoor unit installation across multiple floors
- Industrial chiller plant-room construction and pipework
- AHU/FCU installation and ductwork fabrication
- Cooling tower installation and water treatment setup
- BMS (Building Management System) integration
Commissioning & Handover
Every Cooltech installation ends with a full commissioning and testing phase. We verify that the system operates at its rated performance, that all controls and safety devices function correctly, and that your team is trained on day-to-day operation before we hand over the project.
- System startup and performance verification
- Refrigerant leak testing and charge optimisation
- Controls, BMS, and thermostat calibration
- Performance data logging and documentation
- Operator training for your maintenance team
