LTG Air Diffusers Meet Highest Standards for Quality and Efficiency
For almost 90 years, LTG has been a pioneer in air and air conditioning technology, always a step ahead with trailblazing innovations. When it is crucial to achieve ideal environmental conditions for people and products, LTG creates inspiring, tailor-made comfort air technology solutions, including air diffusers, air-water systems (such as induction and fan coil units) and products for air dis-tribution (flow rate controllers and shut-off valves).
Air diffusers are most important for operation and ef-ficiency of air conditioning and ventilation systems. They allow ideal distribution of conditioned air within a room, as well as effective removal of thermal loads – impor-tant criteria for health and well-being. Even under the most demanding conditions, LTG air diffusers meet all important requirements and set the benchmark in their class.
© LTG Incorporated4
LTG air diffusers can be installed in ceilings, walls and floors. Special diffusers are availa-
ble for specific applications. The choice of air diffuser depends on building type, building
use and interior design specification.

Air Diffusers for Ceiling Installation
LDB
Advantages
Comfortable:n High induction air diffusers ensure rapid mixing
of supply and room airn Uniform, optimal flushing of the room with fresh
airn Pleasant indoor conditions due to uniform
temperature distribution
Quiet: Low-noise air distribution, due to aerodynami-cally optimized inner cylinder contours
Variable: Limitless options for design, color and surface appearance, can be perfectly integrated in all ceilings, due to a wide selection of border profiles
Flexible: Can be adjusted to individual room conditions without affecting performance (even retroactive)
LDB linear air diffusers with variable settings supply all rooms with fresh air in the
optimum way and provide comfortable room conditions.
Profiles and cylinders are available in all color systems (e.g. RAL, Pantone …) and can be combined individually
LTG System clean® – Unique and Ingenious!
Contaminants of the room air like dust, tobacco smoke, carpet abrasions or grease deposit around the ceiling diffuser. The LTG System clean® prevents surface staining almost completely by providing a screen of clean supply air across the ceiling. Benefits: The costs of renovation and maintenance are considerably reduced.
The LTG System clean® is available for the products LDB, LDK-B and LDR (see pages 8-9, 13-15 and 23).

LDR and LDB 12/M LTG System clean®
Circular and Metal Air Diffuser
LDR and LDB 12/M LTG System clean®
The right diffuser for every requirement – in an attractive look and with highest
thermal comfort.
Advantages LDR
Limitless design options – whether as a visible de-sign element with straight or curved lines, or almost invisible: any requested shape and color available
Different flow configurations through adjustable elements
A safe investment: Easy to adjust later on to chan-ged room conditions
Customized solutions on request.
Advantages LDB 12/M LTG System clean®
Vandalism-proof and non-flammable: the success-ful LDB-series now also available made entirely from metal
Quiet: Low-noise air distribution through aerodi-namically optimized inner cylinder contours
Narrow and unobtrusive – perfectly integrable into train ceilings
Advantages
Comfortable: n rapid mixing of fresh air and room air through highly inductive multi-single-jet technologyn uniform, ideal flushing of the room with fresh air
Flexible: Individually configurable air flow pattern depending on usage area – from the entrance area to the passenger cabin, from museum to show-room
Low maintenance: minimum surface staining near the diffuser thanks to patented LTG System clean®

Special Diffusers
Step Diffuser
BLQ
Advantages
Uniform air distribution, without draft, at large temperature differences
Discrete: Installation into steps allows the outlet to blend in with existing architecture
Color scheme based on customer´s individual choice, and available in any color system, such as RAL, Panto-ne and many more. Custom designs (such as anodized or stainless steel) upon request.
Special dimensions upon request.
The BLQ step diffuser ensures effective ventilation of large rooms and is especially
suitable for cinemas, theatres or concert halls.

BLQ, DLD and DLQ
Displacement Air Diffusers
DLD and DLQ
Advantages DLD
High-output: High cooling and heating performance possible (air volume 600-5500 cfm)
Space-saving: a single device for heating and coo-ling
Variable use: at ceiling heights from 10´ to 35´
User-friendly, due to individually adjustable air stream
Pleasant, uniform temperature air distribution with no risk of draft, even when installed inside the occupied zone
Advantages DLQ
Especially well-suited for work areas where over-head ventilation is not possible or where inductive mixed ventilation is not desired
Very quiet with large air volumes: NC 20 at 600 cfm
Flexible: Can be installed up to 14´ high or on the floor
Pleasant and draft-free, but still extremely powerful (air volume up to 1100 cfm)
Especially suited for industrial and production halls, lobbies, entrance and work
areas, as well as sports facilities.

Your advantages
� Cost optimized from the very beginning: In-vestment cost, energy consumption and ope-rating cost can be reliably calculated and spe-cifically reduced in the planning stage.
� Implementation risks can be almost comple-tely eliminated.
� User-friendly and comfortable: The grea-test possible thermal and olfactory comfort through simulation and testing
� Safety when renovating air systems
� Reduced on site commissioning due to factory presets.
� Choice of the best climate system design to suit each building type
� Benefit from our modern development center with various flow laboratories, reverberation chamber, a calorimetric test stand and simulati-on tools for optimizing your project.
LTG Engineering Services –
more safety for your investments!
LTG Engineering Services offer reliable and detailed reports with recommendations re-
garding function and costs for comfort air technology installations prior to final design.
As early as the initial design concept for a new building or a renovation, we determine
facts and data precisely for you to secure your investment. Benefit from decades of expe-
rience and expertise!

Our services
� Realistic space flow tests in various scales (model tests or full scale) for simulating and optimizing of ventilation and temperature sys-tems
� Comfort parameter measurements according to DIN EN ISO 7730, and room conditioning eva-luation in the lab and on site
� Evaluation and optimization of existing ventilati-on systems and devices
� Evaluation and visualization of air flows, and calculation of pressure losses, heat flows, ventilation efficiency and much more, inclu-ding Computional Fluid Dynamics (CFD) simu-lation
� Dynamic building simulation for calculating room conditioning and energy consumption of free or mechanically ventilated buildings (dai-ly temperature variation, heating and cooling loads)
� Acoustic and aerodynamic investigations – on site, if desired – for assessing noise, sound le-vel, attenuation characteristics, flow rate and pressure loss of air flow products and devices
� Implementation and validation of your design ideas through construction, measurement and cost optimization
� Comparative studies of various room conditio-ning systems as to cost of investment, operati-on and life cycle cost
