Generators

FunctionIndependent supplemental powergeneration/storing for refrigeratorboxcars

Product RangeSet of hydraulic generators” 400 V-3ph/50 Hz” 15 - 30 kVa” including fittings for installation

Air Diffusers type LDB

FunctionHigh cooling capacity, high airexchange and thorough rinsingwith fresh air, noiseless andwithout draft phenome-na even with low ceiling heights.

Fast reduction oftemperature and velocity

differences between suppliedair and room air within the short-

est distance from the diffuser.

Product Range” for installation in ceilings, walls,

perimeters, floors” varnished in any color (RAL), anodized,

chromium-plated or gold-plated ” single-, dual-, three-, and four-slot

version ” all-metal versions available (type LDW)

LTG System clean®

Airborne particles such as dust, tobaccosmoke, carpet abrasions, or grease easilydeposit in close proximity to the airdiffusers. The LTG System clean® almostcompletely avoids these deposits. Part ofthe clean supply air is directed as an aircurtain along the ceiling thus keepingairborne dust particles from polluting the ceiling. Consequently, maintenanceexpenses are significantly reduced.

Tangential Fans

FunctionUniform air flow over large surfaces.Therefore, advantageous for a variety of processes such as heating, cooling,drying. The airflow is turned 90° to savespace.

Product Range” Air/gas temperature: -40 to +700°C” Impeller diameter: 25 to 800 mm” Sizes: 60 to 4500 mm” Airflow rate: up to 160 000 m3/h” Static pressure: up to 1650 Pa” Versions with electrical heat register

up to 1.5 kW

Components and SystemsRail vehicles are in use for long periods of time. That’s why only thebest is good enough also when it comes to details.

Component functions are also essentiallyaffected by factors such as the installationsituation, sizing of the A/C supply media,or a component setting matching actualrequirements. LTG Engineering Servicessupport the customer to achieve bestresults with our products when used invehicles, e.g. through room airflow testsusing scale models, CFD (ComputationalFluid Dynamics) room airflow simula-tion, computation and dynamic simula-tion of air duct and water pipe systems.

Most tasks have been completed to our customers’ satisfaction not by rein-venting the wheel but by coordinatingthe knowledge and experience of theuser and of LTG Aktiengesellschaft specialists.

Our state-of-the-art R&D lab offers anymeans to provide computational andexperimental air technology services,thus ensuring optimum conditions toanswer, in detail and professionally, any question.

Optimizing the life support system withinthe European module of the InternationalSpace Station ISS.

The air conditioning unit type HDCSrequires little room, mixes the extremelycold supply air in low constructionvolume with the warm air in thecompartment, avoids condensation, andcreates a comfortable air flow. Integratinga sound absorber and a flow ratecontroller in the unit also reduces instal-lation time.
