HVAC & Commercial Building Cooling Solutions
Commercial buildings, industrial campuses and large HVAC plants need stable heat rejection for chillers, condenser-water loops and building services. HACST supplies open and closed-circuit cooling towers, evaporative condensers and air-cooled heat exchangers for new installations, upgrades and replacement projects.

Common HVAC Cooling Duties
- Chiller condenser-water systems.
- Commercial and industrial building HVAC plants.
- District cooling and campus utility systems.
- Data, telecom and mixed-use facility support systems.
- Replacement and capacity-expansion projects.
What Should Be Evaluated?
HVAC heat rejection depends on design load, entering air conditions, water temperature, flow, sound limits, available roof or plant-room space, maintenance access and local water restrictions. A practical selection should also consider part-load operation and seasonal control.
Open Cooling Towers
Open towers are commonly considered for central condenser-water systems where the water-treatment and filtration strategy is established.
Closed Circuit Cooling Towers
Closed-loop towers can separate the primary fluid from the evaporative circuit and support applications where fluid cleanliness or system separation is important.
Dry and Adiabatic Cooling
Dry and adiabatic systems can be considered where water use, discharge or seasonal operation is a major design factor.
HACST Selection Process
- Confirm design and part-load cooling duties.
- Review flow, entering and leaving temperatures and ambient conditions.
- Check roof loading, footprint, sound, plume, access and service routes.
- Compare wet, closed, dry and adiabatic options.
- Prepare a maintainable configuration with suitable controls.

Frequently Asked Questions
Are dry coolers suitable for every HVAC plant?
No. The answer depends on required water temperature, ambient conditions, available airflow, fan power, footprint and seasonal operation.
Can HACST support replacement projects?
Yes. Existing equipment dimensions, connections, pump duty, controls and access should be reviewed before selecting replacement equipment.
