LTG products meet highest standards for quality and efficiency
For 90 years, LTG has led the way of air and climate technology, always a step ahead with trailblazing innova-tions. When it is crucial to achieve ideal environmental conditions for people and products, LTG creates inspi-ring, tailor-made comfort air technology solutions: These include air-water systems (such as induction units and fan coil units), products for air distribution (flow rate controllers and shut-off valves) and air diffusers.

Example System C of the VDI 3804:Room temperature and ventilation withinduction devices
In the VDI 3804 all essential ventilation and air condition concepts are compared. To VDI 3804´s development LTG Aktiengesellschaft essentially contributed. On this basis, we offer high-performance products for any requi-rement and installation situation. These include air-water systems, air diffusers or air distribution components. LTG engineering services provide you with decades of expert know-how in comfort air and process air techno-logy, as well as a state-of-the-art lab. We will gladly support you in selection of the best system. Contact us!
LTG System Solutions & Innovations
Mixed/Displ. Air FlowTangential Air FlowDisplacement Air Flow
The mixed/displacement air flow developed by LTG and assumed into the VDI 3804 permits high cooling output at high thermal comfort. It can be implemented in any LTG device type with optimised air distributors. The above chart shows the areas of application of different flow forms that are es-sentially defined by thermal comfort. The ideal flow shape for the project-specific parameter cooling output and supply air flow rate can be implemented with different LTG air-water systems then. We per-form optimisation for special requirements within the scope of our engineering services.

Induction Technology – comfortable and efficient
LTG induction units have been developed further continually since the first patent was registered by founder Dr. Albert Klein for an induction plant in 1915.
Benefits
� No additional fan needed in the unit
� Silent, long service life and low maintenance
� Low energy costs / variable ventilation
� High cooling and heating output
� Cooling / heating and fresh air supply in one unit
Induction Units
Induction
The Induction Principle
Air flowing through a nozzle forms a free jet. It induces the surrounding air layer along at its edges and thus enlarges the flowing air volume. This „induction“ takes place within the induction device. A special construction entrains room air (secondary air) through a heat exchanger, where it is cooled or heated. Together with the fresh air (primary air) the supply air then returns to the room for a comfortable climate.
Induction principleInduction device chart
The Evolution of Induction
LTG Air-Water Systems Induction Units / Chilled Beams
The System SmartFlow
The LTG System SmartFlow offers best comfort and energy consumption even under changing load stations. The ideal flow form is selected depending on required cooling output and fresh air volume. For this, the air nozzles are opened and the cold water valves are controlled. This ensures best comfort, acoustics and energy efficiency for any load case with a single device. Manual (different room use) or automatic (occupancy or CO2-controlled) regulation is possible. In contrast to conventional induction technology, this permits adjustment of cooling output and fresh air supply to the specific requirements.

� Part of LTG SystemDesign – for a consistent look
LTG fan coil units use both radial and cross-flow fans to implement the best flow and acoustics for different installation situations. Flexible and high-performance.
LTG fan convectors with cross-flow technology are characterised by a particularly even and large-area flow through the heat exchanger. Low pressure loss and low noise level with high cooling or heating output.
The latest drive technology generation (EC-technology) also permits capacity modulation at the lowest electrical energy consumption.
The Air Conditioning Classic – energy-efficient and low-noise
The principle: A fan conveys room air through a heat exchanger and cools or heats the room.

Differential pressure + Damper setting = Flow rate
Contrary to common measuring techniques, the differential pressure is not measured using an upstream element such as orifice plate or differential pressure sensor.
Flow rate controllers VREactive and VRFactive measure the differential pressure directly in the damper blade area (stronger signal due to locally accelerated air flow).
Unique and Brilliant – LTG System ActiveControl
The differential pressure is measured in the damper blade area. This results in
– increased measuring signal due to the local acceleration of the air flow– highest measuring accuracy for small air flow rates– minimum pressure loss

A lot of experience collects across a corporate his-tory of about 90 years. The range of our references is accordingly wide, reaching from renovation of the air conditioning technology of monument-protected old buildings to air conditioning units for pioneering buildings or solutions for highly technological production processes. We ensure good air even in Egyptian pyramids or in space flight.
What many of these projects share is an unusual task that can only be mastered with lots of commit-ment, know-how and creativity. This was the case even in the early days of LTG, when founder Dr. Klein constructed the first air conditioning systems, and this will continue to characterise our company in future. We continue development where classic concepts end.
Challenge us and become our future reference. Our experts in room air and process air technology will gladly develop a concept for you that will not only meet your requirements, but also convince you with energy efficiency and investment safety.
