Detailed Product Information
This document provides detailed information on various ventilation and air conditioning units offered by LTG Aktiengesellschaft, focusing on fan coil units, induction units, and decentralized ventilation systems. It highlights the benefits, technical specifications, and applications of each product type.

Induction Units
HFB / HFBsf Floor Induction Unit: Designed for challenging installation scenarios, these units offer high natural convection for heating without primary air. They are easy to maintain and integrate seamlessly with other systems for a consistent room appearance. Key specifications include a cooling/heating output of up to 1500/2400 W and a primary air flow rate of up to 160 m3/h.

Fan Coil Units
General Benefits: These units are energy-efficient, low-noise, and offer demand-controlled air conditioning. They utilize smart EC-technology for low power consumption and rapid response in cooling and heating.
LVC System Indivent®: Offers optimum thermal comfort with low air turbulence and efficient ventilation. It allows for architectural design freedom and integrates easily into any ceiling.
VKH and VKE: These ceiling installation units provide high cooling output with low noise and are maintenance-friendly.
KFA cool wave®: Provides gentle cooling with very low air speeds and noise levels, suitable for supplementing passive cooling systems.
VFC and QVC Sill Units: These units are energy-efficient and offer high comfort through mixed/displacement ventilation. They are suitable for narrow and low sills.

Decentralized Ventilation Systems
General Benefits: These systems do not require a central air conditioning plant, allowing for lower construction costs and efficient space use. They offer high energy efficiency with demand-controlled ventilation and heat recovery.
FVS Univent®: Ideal for schools and meeting rooms, this unit provides energy-saving ventilation with efficient heat recovery and CO2-controlled regulation.
FVM, FVD, and FVPpulse: These units offer flexibility in installation and are highly economical with reduced maintenance costs. They provide high thermal comfort with pulsating air flow.

LTG Engineering Services
LTG offers comprehensive engineering services to optimize investment costs, energy consumption, and operation costs. They provide realistic room flow tests, comfort parameter measurements, and evaluation of existing systems to ensure optimal performance and security for investments.

Overview of Services
LTG Engineering Services offers a comprehensive range of services aimed at optimizing building climate and energy efficiency. These include the calculation of pressure losses, heat flows, and ventilation efficiency, supported by Computational Fluid Dynamics (CFD) simulations. Additionally, dynamic building simulations are conducted to assess room climate and energy consumption for both naturally and mechanically ventilated buildings, considering daily temperature variations and heating/cooling loads.

Acoustic and Aerodynamic Assessments
On-site acoustic and aerodynamic investigations are available to evaluate noise levels, sound attenuation, flow rates, and pressure losses in climate-control products and devices.

Design Implementation and Validation
LTG provides support in implementing and validating design ideas through construction, measurement, and cost optimization. Comparative studies of various room climate systems are also conducted to analyze investment, operational, and life cycle costs.

Induction Units Induction Units Induction Induction Units 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. 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...
