Central HVAC Solutions
Engineered Cooling for Large-Scale Applications
Large buildings and complex facilities require more than individual cooling units.
ERATEC provides complete Central HVAC solutions designed around the actual cooling load, operating conditions and technical requirements of each project.
From system design and equipment selection to supply, installation, commissioning and after-sales support, we deliver integrated cooling solutions engineered for reliable long-term operation.
Complete Central HVAC Solutions
A Central HVAC system brings multiple components together to provide cooling across an entire building or facility.
ERATEC designs and delivers integrated systems that may include:
Chillers
Air Handling Units (AHUs)
Fan Coil Units (FCUs)
Pumps and associated equipment
Ductwork and piping networks
Control systems
HVAC system integration
Every configuration is selected according to the requirements of the project rather than applying the same system design to every building.
Designed Around the Actual Cooling Load
Correct system sizing is one of the most critical factors in Central HVAC design.
An oversized system can increase initial and operating costs, while an undersized system may struggle to maintain the required indoor conditions.
ERATEC evaluates the project’s cooling requirements, occupancy, building use, operating hours and environmental conditions to develop a system configuration based on the actual load profile.
Chiller Systems
Chillers form the core of many large-scale Central HVAC applications.
ERATEC provides chiller-based solutions engineered according to project capacity, operational requirements and building conditions.
The complete system is designed to work as one integrated cooling infrastructure, connecting chillers with pumps, AHUs, FCUs and the associated distribution network.
Air Handling Units — AHUs
Air Handling Units are responsible for conditioning and distributing air throughout different areas of a building.
Their selection and configuration depend on factors including airflow requirements, cooling loads, filtration requirements and the intended application of each space.
ERATEC integrates AHUs into the overall HVAC design to ensure that air distribution works effectively with the central cooling system.
Fan Coil Units — FCUs
Fan Coil Units provide localized cooling across different zones within a Central HVAC system.
They can be selected and distributed according to room layouts, individual zone requirements and the architectural conditions of the project.
This allows the central system to serve multiple areas while responding to different cooling requirements throughout the building.
More Than Equipment Selection
Central HVAC performance depends on how every component works together.
Chillers, AHUs, FCUs, pumps, piping, ductwork and controls must be correctly selected, sized and integrated.
ERATEC approaches Central HVAC as a complete engineering system rather than a collection of individual equipment.
Engineering from the Start
Load Calculations
Evaluating the cooling requirements of the building and its individual zones to determine the required system capacity.
System Selection
Selecting the appropriate Central HVAC configuration according to project scale, application and operating conditions.
Equipment Selection
Determining suitable chillers, AHUs, FCUs and associated equipment based on the engineering requirements of the system.
Distribution Design
Planning the piping, ductwork and air distribution infrastructure required to deliver cooling throughout the facility.
System Integration
Ensuring that the different mechanical and control components operate together as one coordinated HVAC system.
Built for Demanding Applications
Central HVAC solutions are particularly suited to projects with large cooling loads, multiple zones and extensive operating requirements.
Commercial Buildings
Integrated cooling for offices, business complexes and large administrative facilities.
Hotels & Hospitality
Centralized systems capable of serving guest rooms, public areas and service spaces with different cooling requirements.
Healthcare Facilities
HVAC solutions designed around the specific operational and air-conditioning requirements of medical environments.
Industrial Facilities
Large-scale cooling systems engineered according to facility loads and demanding operating conditions.
Mixed-Use Developments
Central HVAC infrastructure capable of serving different building functions within the same development.
Energy Efficiency Starts with Engineering
Reducing HVAC energy consumption is not achieved by equipment efficiency alone.
System sizing, equipment selection, load management, controls and operating strategy all influence the total energy performance of a building.
ERATEC considers these factors during the engineering process to develop a Central HVAC solution that meets cooling requirements while supporting more efficient long-term operation.
Designed for Long-Term Operation
A Central HVAC system is a long-term infrastructure investment.
For that reason, the engineering process must consider more than initial cooling capacity.
Maintainability, accessibility, system reliability, future operation and equipment lifecycle all influence the final design.
ERATEC develops solutions with the complete operating lifecycle of the system in mind.
From Design to Operation
ERATEC provides support across the complete Central HVAC project lifecycle.
Engineering & Consultancy
Technical assessment, load calculations and system planning.
Equipment Selection
Selection of the appropriate HVAC equipment according to project requirements.
Supply
Providing the equipment and components required for the approved solution.
Installation
Executing the HVAC system according to the approved engineering design.
Testing & Commissioning
Testing system operation and configuration before project handover.
After-Sales & Maintenance
Preventive and corrective maintenance to support reliable system performance throughout its lifecycle.
One Project. One Integrated HVAC Solution.
Every facility has a different load profile, operating environment and set of technical requirements.
ERATEC brings engineering, equipment and execution together to deliver Central HVAC solutions designed around the project from the beginning.
