W-EC and W-EC 2R models: these models also reach a maximum range of 7.5 meters, thanks to the high-efficiency fan and electronically commutated (EC) motors, which guarantee a powerful and constant air flow.

This capability makes the HUMMER Series air curtains ideal for applications in industrial spaces, such as warehouses and workshops, where large openings need to be covered to prevent heat loss or cold air entry.

The electronic direct current (EC) motors used in some HUMMER Series models are highly efficient electric motors that combine the advantages of direct current (DC) and alternating current (AC) motors. Here's how they work and their main benefits:

Operating principle

THE EC motors They are powered by direct current, but use a integrated electronic control to convert AC mains power into DC and manage the electronic switching of phases. This integrated control allows the motor speed to be precisely adjusted, improving performance and energy efficiency.
Switching takes place without mechanical contacts thanks to electronic circuits, which replace the traditional commutators and brushes of DC motors. This reduces wear and maintenance.

Advantages of EC motors

High energy efficiency:
- EC motors are much more efficient than conventional motors, with efficiencies that can exceed the 90%. This translates into lower energy consumption and reduced operating costs.
Precise speed control:
- Thanks to the integrated electronic control, EC motors allow you to precisely adjust the speed of the air flow. This allows you to adapt the performance of the air curtain to your specific heating or cooling needs, improving comfort and efficiency.
Silent operation:
- EC motors produce less noise than traditional AC motors due to their brushless construction and optimized speed control.
Low maintenance:
- The absence of brushes and mechanical commutators reduces wear and maintenance requirements, increasing motor reliability and extending its life.
Compatibility with ErP 2015 regulation:
- EC motors meet the requirements of the European Directive ErP 2015 (Energy-related Products), which imposes energy efficiency standards for energy-using products.

Applications in HUMMER Series models

In HUMMER Series models that use EC motors (e.g., W-EC And W-EC 2R), these motors offer advanced performance control and significant energy savings, making them ideal for use in industrial and commercial environments with high demands on efficiency and airflow regulation.

In summary, EC motors represent an advanced technology that combines energy efficiency, precise speed control and low maintenance, improving the overall performance of the HUMMER Series air curtain.

Installing a HUMMER Series water air curtain requires compliance with some fundamental requirements to ensure safe and efficient operation. Here are the main installation requirements:

1. Mounting position

The air curtain should be mounted above the door opening so that the air flow covers the entire width of the entrance. It is important that the curtain is centered and aligned correctly to create effective separation of the inside and outside air.
The maximum installation height must be compatible with the barrier range, which for the HUMMER Series can reach up to 7.5 metres.

2. Support structure

You need to make sure that the supporting structure (wall or ceiling) is able to support the weight of the barrier, which can vary from 40 to 70 kg depending on the model. Assembly must be carried out using the fastening systems supplied or specified by the manufacturer.

3. Hydraulic connection

For models with water heat exchanger, it is necessary to connect the air curtain to the central heating system which supplies hot water. The water temperature should be adequate (generally up to 120°C), and the maximum permissible operating pressure is 1.6 MPa.
THE hydraulic connectors of the barrier are generally from 3/4 inch, and the system must be equipped with control valves to regulate the flow of water.

4. Power supply

The barrier requires a Power supply 230V/50Hz. It is important to ensure that the electrical system is sized correctly to support the power of the engine and control systems.
The installation should include a safety switch so that the power can be easily disconnected if necessary.

5. Ventilation space

Sufficient space must be provided around the air curtain to allow for proper ventilation. This prevents overheating of the components and ensures adequate airflow.

6. Automation and control

HUMMER Series models can be equipped with automation accessories, such as temperature sensors, speed controllers or chronothermostats, to automatically regulate the operation of the barrier. These devices must be installed and configured according to the manufacturer's instructions to optimize the efficiency of the system.

7. IP protection and harsh environments

The HUMMER Series has a IP54 protection rating, which makes it resistant to dust and splashes of water. However, in environments with extreme conditions (such as very high humidity or excessive dust), it may be necessary to take additional protective measures or frequent maintenance.

8. Regulations and safety

The installation must comply with the local regulations on safety and heating systems. It is important that the installation is carried out by qualified personnel to ensure the safety and efficiency of the system.

By following these installation requirements, the HUMMER Series water air curtain can be installed safely and effectively, ensuring optimum thermal protection and reliable operation.

No, the HUMMER Series water air curtain is not designed for direct cooling of environments. Its main function is to create an air barrier that separates the inside from the outside, preventing the dispersion of conditioned or heated air and the entry of air at unwanted temperatures. In this way, it helps maintain the desired internal temperature, reducing the workload of heating or cooling systems.

In water heat exchanger models, the water used is hot, so the air curtain heats the air that blows in. To achieve a cooling effect, a different system would be needed, such as an air curtain designed to work with chilled water or an integrated air conditioning unit.

In summary, the HUMMER Series air curtain is effective in maintaining the thermal conditions already present inside, but does not directly provide cooling or air conditioning.
