Advantages – Induction Technology

LTG induction units of the latest generation are energy-efficient and can be operated and demand controlled

with LTG SmartFlow technology.

Advantages:

Energy Savings

Sustainable: long service life and low maintenance

Silent

High cooling and heating output

Cooling / Heating and fresh air supply in one unit

No fan needed in the unit

– Comfortable and Efficient

Information – Induction Technology

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.

– Comfortable and Efficient

Induction unit Induction principle

Air-Water Systems – Active Chilled Beams HDF / HDFsf

Power meets comfort –

and the highest requirements

Reduced duct sizes due to transport of cooling

energy with water

Energy-efficient with high cooling output and

optimized fresh air quantity (suitable for LEED

certified buildings)

Low-noise and maintenance-free

2-/4-way version for any desired room layout;

integration of extract diffuser unit possible

Space-saving: low installation height

(e. g. HDF-N only 6.3“)


‹#›

Air-Water Systems – Active Chilled Beam HDC

Comfortable even in complex

installation situations.

Energy-efficient by low primary pressures and

high cooling output

Silent: very high-performance at low noise level

Low installation height possible

Two-in-one: Supply air and exhaust air in one

unit

High thermal comfort

Maintenance-friendly construction


‹#›

Air-Water Systems – Induction Unit HFG-MQ

The induction unit for any

application – even for complex

installation and room situations.

High comfort by LTG mixed/displacement

ventilation

Many versions are suitable even for special

requirements like narrow or low sills

High heating / cooling output

Low-maintenance, proven and robust

Air volume and pressure can be selected

individually


‹#›

Air-Water Systems – Induction Unit QHG

The induction unit for

displacement airflow.

Comfortable room climate by low flow speed

High ventilation efficiency: The thermal effects

remove hazardous substances in a targeted

manner

Flexible room design: displacement ventilation

prevents risk of draughts

Air diffusers adjustable to suit installation

situation


‹#›

Air-Water Systems – Induction Unit HFVsf


‹#›


Up-to-date induction technology –

energy-efficient refurbishment

Easy: 1:1 replacement during operation

Reduce energy costs: demand-controlled

ventilation with lowest primary pressures

High user response: Supply air and cooling

variable, extremely low-noise

Robust technology, low-maintenance

Sustainable thanks to flexibility: a unit model

with various comfort stages, easily adjustable

for all types of use in the building

The Evolution of Induction

The Evolution of Induction


‹#›

Air-Water Systems – Induction Unit HFFsuite

Five stars for efficient and

silent ventilation, heating and

cooling without a fan

As quiet as a whisper even at maximum

power: 24 dB(A)

20 % more cooling output than standard

systems – also in a tight space

Maximum thermal comfort: induction control

for individualized user control, adjustable air

baffle elements

Very low operation costs: energy-saving,

maintenance-free and hard-wearing induction

technology

The perfect alternative to fan coil

solutions: easy integration, economical for

retrofit work too


‹#›

Air-Water Systems – Under-Floor Induction Unit HFB / HFBsf

Compact and powerful.

Flexible and efficient.

Dissipates heat and cooling load at the facade

Allows for smaller ducts inside the building

No moving parts results in low maintenance

and extremely long product life time

Low noise level

Does not obstruct window or view

With LTG System Design: for a Consistent

appearance with different floor devices (e. g. with

VKB…)


‹#›

Unit mounted in raised floor

Quiet Tangential Fan with even

velocities over discharge opening

Air inlet on room side

through heat exchanger

Air outlet along facade

All components accessable

through grille

Fan-Coil-Unit VKB - Function

Recirculation

Air

Supply Air

Outstanding performance under demanding conditions.

Unsurpassed in comfort, acoustics and design.

Linear / Swirl Diffusers Displacement Diffusers Floor Diffusers Transfer Air Device Customized Solutions


‹#›

LTG Innovations – the LTG System clean®

Contaminants within the room air like dust, tobacco smoke, carpet abrasions, dust or oil vapor deposit

around the ceiling and diffuser as a result of entrainment. 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

LTG System clean® – unique and ingenious!

The LTG System clean®: part of the supply air is diffused directly along the ceiling and prevents contamination


‹#›

Air Diffusers – Swirl Diffuser DLA

The highly inductive spot diffuser. Can be

applied versatilely in offices, restaurants,

laboratories and shopping centres.

Fresh air everywhere: Optimal, efficient 360-

degree ventilation

Easy to operate: Easy flow rate control

Inexpensive to install: With central fastener up

to an installation size of 625

Flexible: Factory preset swirl disk, fast and easy

to adjust to changed room conditions

Low maintenance: Minimal cleaning necessary,

depending on design

Choice of housings: Rectangular, pyramid or

cylindrical boxes. Pyramid boxes are stackable

for low transport costs


‹#›

Air Diffusers – Floor-mounted Linear Air Diffuser LDU-W

Comfortable and draft-free

heating, cooling and venting.

Quiet and draft-free with highly efficient

ventilation

Energy efficient: Thermal shielding of glass

façades

A unified look meets exacting demands for

attractive design

Height-adjustable feet, easy to align – ideal for

raised access floors

Flexible design of exhaust grid; visual

continuity with other LTG floor units

More security for your investment.
