The modernization of existing HVAC, especially the fans, has a high energy saving potential. At the same time, EC fan technology substantially improves the reliability of the system, reduces maintenance costs, and ensures uninterrupted operation of the air conditioning system.
By replacing old and inefficient fans with modern EC fans, energy, and CO2 savings of up to 50% can be achieved, depending on the building and the system.
Numerous examples of retrofit projects in non-residential buildings (from hotels to airports) show that inversion in substitution of a fan is amortized in a period between two and five years, depending on the system and building.
Sectors for modernization
Which sectors are most recommended in fan substitution? Multiple places has HVAC systems huge and old.
Hotels
Event Buildings
Industrial Buildings
Automotive Industry
Airports
Shopping Centers
Food Industry
Universities
Logistics Industry
Hospitals
Sports Centers
Pharma Industry
Administration Buildings
Therefore, energy savings potential is huge. In addition, in more sensitive applications, the risk of a unit stroke, is practically vanished, because the redundance of an ECFanGrid.
What is an EC FanGrid?
An EC FanGrid consists of several EC fans operating in parallel mounted in a matrix. The flow rate is multiplied proportionally to the number of fans, while the pressure conditions remain constant. EC fans are not only highly efficient, but also have fully integrated electronics, motor and turbine. This allows for simple plug & play solutions for any ventilation need.
In addition, multiple controllable fans can be much better matched to the actual air throughput required, increasing efficiency at any duty point.
The EC FanGrid Retrofit system is ideal for replacing old, inefficient belt-driven fans in ventilation units, regardless of the brand used. The retrofit system is highly adaptable and always suitable.
Airtecnics supplies all the necessary components, from the fans and the AHU retrofit wall to the sensors and the control and regulation cabinet.
Energy Savings
Obsolete fans are one of the main causes of excessive energy consumption in HVAC systems.
In comparison, modern, efficient fans save up to 50% of energy consumption. In addition, the operating cost of the system is reduced by up to 70%.
Easy installation
ECFanGrids are ideal for retrofitting existing ventilation and air conditioning installations, especially when replacing a large centrifugal fan. Due to the smaller size of the components, the ECFanGrid can be transported into the building and installed by one or two people without the need to make structural changes to the building to move the equipment.
Easy maintenance
Unlike conventional belt-driven fans that emit dust into the air due to belt abrasion, EC fans are non-contaminating. Most ECFanGrids are supported only by the structural wall and, due to their smaller size, allow for better cleaning and maintenance.
Reliability
EC FanGrid offers a tremendous degree of reliability due to its redundancy. In the unlikely event of a fan failure, the remaining fans automatically increase speed to compensate for the loss in airflow.

Who benefits from a retrofit project?
Depending on your role in the project, your priorities may vary depending on how important they are to you. EC FanGrid systems are designed to meet the needs of all parties involved.
For the property owner, energy savings and system reliability are most important. Professional measurements are provided to determine the actual energy consumption and show the potential for energy savings. In addition, reliability is greatly increased by the redundancy of the system.
For the developer, time is the key factor and he needs to find an optimal solution quickly. Only four pieces of information are required to issue a complete quotation within a few hours: flow rate, pressure, height and inner width of the AHU.
For the installer or builder, practicality is most important. Installations must be facilitated with systems that include all the necessary components and that are manageable, easily transportable between two people and can fit into existing elevators and stairs. Our ECFanGrid system meets all these requirements, you will not have to worry about anything, we deliver the solution tailored to your project.
Projects
In airports, public buildings, office complexes, production plants or hotels, EC FanGrids are used where air handling units are operated uninterruptedly or almost around the clock. Here are some examples of fan replacements that are already in operation.
