AIR CURTAINS AND AIR CURTAIN-FAN HEATER UNITS

Product catalog summary
Overview: The document provides comprehensive information on ELiS and Slim air curtains and air curtain-fan heater units. These devices are designed to create an air barrier in door openings, reducing heat loss and enhancing energy efficiency in settings such as hotels, offices, shopping centers, and industrial buildings.
Technical Specifications: The document details specifications for models including ELiS B, Slim, ELiS AX, ELiS T, and ELiS G. Key parameters include installation height, airflow rates, acoustic pressure levels, and heating capacities. For instance, the ELiS AX model offers heating capacities from 7.9 to 41.4 kW and can be installed both vertically and horizontally.
Applications: Air curtains are suitable for commercial buildings, logistics centers, and industrial halls, effectively maintaining thermal comfort by preventing cold air inflow in winter and warm air in summer.
Testing and Standards: The document emphasizes laboratory testing for product quality and effectiveness, conducted according to ISO standards. FLOWAIR, a EUROVENT association member, is involved in developing guidelines for energy savings and air curtain effectiveness.
Innovations: Optiflow technology is introduced, enhancing energy efficiency and thermal comfort by ensuring even airflow distribution and creating a robust air barrier. Adjustable air outlet louvres provide optimal room conditions and protection against external factors.
Installation and Control: The ELiS AX model offers flexible installation options with built-in automation for easy control. The T-box Zone Controller allows intelligent management of the air curtain's operation, enhancing user convenience and energy efficiency.
Conclusion: The document highlights the benefits of air curtains, such as energy savings, reduced investment risk, and improved thermal protection, along with a commitment to continuous product improvement through rigorous testing and adherence to international standards.
Specifications: Models like ELiS AX45-W3R and ELiS AX45-W4R have airflow capacities from 2400 m3/h to 6100 m3/h. Heating capacities vary, with detailed data on air and water temperatures, water flow, and pressure drop in heat exchangers.
Technical Data: Slim air curtains come in three lengths (1 m, 1.5 m, 2 m) and versions (W - water heat exchanger, N - without heating elements, E - electric heaters), suitable for horizontal and vertical installations in commercial spaces.
Installation and Control: Installation dimensions and options include brackets and rods for mounting. Control options feature built-in motion sensors, TS controllers, and T-box controllers for intelligent management and integration with building management systems.
Advantages: Slim air curtains offer intelligent savings with motion sensors, air quality improvement with external filter modules, and discreet operation, fitting 99% of door openings.
Additional Features: Special painting options, connection diagrams, and CAD drawings are available for detailed installation planning.
Performance Data: Airflow ranges from 2000 to 6600 m3/h for ELiS B models, and up to 12800 m3/h for ELiS G models. Heating capacity varies significantly across models, with detailed tables showing performance at different temperatures. Acoustic levels are specified according to ISO standards.
Applications: ELiS B is suitable for shops, restaurants, and exhibition rooms, designed for ceiling installation. ELiS G is intended for warehouses, halls, and logistics centers, capable of horizontal and vertical installation.
Additional Features: Controllers include TS (3-step fan speed controller with thermostat) and T-box (intelligent controller with touch screen). Sensors such as magnetic and mechanical door sensors are available for integration.
Control Systems: The document describes TS Controller for basic regulation, T-box Controller for intelligent regulation, and T-box Zone Controller for advanced zoning functions, managing fan speed, temperature settings, and integration with a Building Management System (BMS).
Installation Elements: Details on door sensors, valves, and splitters for controlling air curtains, along with brackets and consoles for installation, specifying compatibility with different ELiS models.
Integration with FLOWAIR System: The FLOWAIR system allows integration of multiple devices under a single controller, offering advanced control features such as antifreeze protection, delay time, and idle speed settings.
Key Features: The document highlights the ability to control multiple units, set individual zone temperatures, and schedule operations, emphasizing the energy efficiency and intelligent management capabilities of the T-box controller.

TEST OF AIR CURTAIN EFFICIENCY IN RELATION TO TEMPERATURE DIFFERENCES The test was carried out in the FLOWAIR R&D lab, in order to measure the effectiveness of the air barrier created by the air curtain relative to the temperature difference. Measurement of air temperature difference between the „cooling” and „heating” chambers upon opening the door - with curtain in Off mode. Chamber 1 simulates external conditions (air temperature is 2°C), and chamber 2 simulates conditions inside the building (air temperature is 20°C). Simulation of external conditions - two closed chambers (cooling and heating)....

Optiflow technology ensures an energy efficient airflow through the aircurtain and guarantees high thermal comfort. How does it work? The air enters the curtain via 2 air intakes: the lower and the upper intake Then the air stream flows evenly throughout the entire area of the heat exchanger. Next the hot air stream passes through the fans and compression chamber and s directed towards two adjustable, dynamic outlet louvres which create 3 separate air streams, enuring an excellent air barrier and additional thermal comfort in the room. even temperature distribution throughout the entire area...
