Product catalog summary
Overview of Ceiling Swirl Diffusers:
The document provides a comprehensive overview of Type DCS ceiling swirl diffusers, designed for use in both comfort and industrial zones. These diffusers are suitable for supply and extract air, handling both variable and constant volume flows. They are particularly compatible with T-bar ceiling systems and are ideal for comfort zones due to their high induction levels and efficient swirl effect.

Specifications:
- Nominal sizes for diffuser face: 593, 598, 618, 623 mm
- Nominal sizes for swirl unit: 125, 160, 200, 250, 315, 400 mm
- Volume flow rate range: 4 – 260 l/s or 16 – 936 m³/h
- Temperature difference for supply air to room air: –12 to +10 K
- Suitable for room heights up to 4 m

Design and Construction:
The diffusers feature a perforated face plate made of galvanized sheet steel, powder-coated for durability. They include a swirl unit with fixed air control blades for horizontal swirling air discharge. The construction allows for horizontal or vertical duct connections, with optional plenum boxes.

Variants:
- DCS-P: Perforated diffuser face
- DCS-N: Unperforated diffuser face
- DCS-C: Diffuser face with exposed discharge nozzle

Installation:
The diffusers can be installed with exposed or concealed T-bars and are compatible with circular ducts to EN 1506 or EN 13180 standards. They are maintenance-free and designed for easy inspection and cleaning according to VDI 6022.

Materials and Safety:
The materials used include galvanized sheet steel and aluminum, with mineral wool lining for the plenum box. The mineral wool is non-combustible, biosoluble, and safe according to German and EU standards.

Technical Data and Performance:
The document provides detailed tables for quick sizing, showing volume flow rates, sound power levels, and differential pressures for various configurations. The diffusers are designed to minimize noise and turbulence in occupied zones, ensuring efficient room ventilation.

Order and Customization:
The document includes an order code system for specifying different configurations and finishes, including RAL CLASSIC colors for exposed surfaces.

Dimensions and Weight:
Detailed tables provide dimensions and weights for each diffuser variant, specifying parameters such as outer diameters, heights, and effective air discharge areas. Weights range from 1.9 kg to 12.9 kg depending on the size and variant.

Installation Details:
Installation is suitable for rooms with a clear height up to 4.0 m, with options for flush ceiling installation and both horizontal and vertical duct connections. Specific installation variants include DCS-*-V-A, DCS-*-H-A, and others, each with unique features like suspension lugs and T-bar concealment.

Basic Information and Nomenclature:
The document provides a comprehensive nomenclature for understanding diffuser dimensions, including terms like outer diameter (ØD), height (H), and effective air discharge area (Aeff). Sound power levels and volume flow rates are also defined, with all sound power levels based on 1 pW.

Key Parameters:
Effective air discharge areas (Aeff) are specified for each nominal size, ranging from 0.0034 m² to 0.0355 m². The document includes detailed tables for dimensions and weights, aiding in the selection of appropriate diffuser models for specific applications.

Type DCS-4

Ceiling swirl diffusers with perforated face plate Functional description Ceiling swirl diffusers in air conditioning systems ​ create a swirl to supply air to rooms. The resulting ​ airflow induces high levels of room air, thereby ​ rapidly reducing the airflow velocity and the ​ temperature difference between supply air and ​ room air. Ceiling swirl diffusers allow for large ​ volume flow rates. The result is a mixed flow ​ ventilation in comfort zones, with good overall ​ room ventilation, creating only very little ​ turbulence in the occupied zone. Type DCS ceiling swirl diffusers have fixed...
