Advantages of the modular systems LUEFTA LS and LUEFTA MAX:

• All LUEFTA system components can be combined with each other as desired.
• All accessories such as supplementary heating registers, three-/four-way valves, heat pumps etc., can be integrated into the system scheme without problem.
• Even with limited space inside the installation room the individual components of the heat recovery system can be easily set-up.
• Exchanging individual modules within the system is possible without problem. Due to the modular design this can be accomplished without exchanging the entire system.
• The high-performance components from the heat exchanger up to the fan etc. comply with the requirements of major projects.
• All systems no matter whether central or semi-central are suitable for passive houses. 
• The heat exchangers stand out due to low pressure loss, a high degree of heat recovery and extremely good tightness.

Application fields for the different sizes of the LUEFTA ventilation systems

• LSD 150 DC - apartment units up to about 120 m² floor space
• LSD 300 DC - apartment units up to about 150 m² floor space
• LS 300 DC - apartment units up to about 150 m² floor space
• LS 450 DC - one- and two-family houses up to about 200 m² floor space
• LS 600 DC – one- and multi-family houses, office space, restaurants
• LS 800 DC – multi-family houses, office space, restaurants

• MAX 1000 DC air volume up to about 1000 m³/h
• MAX 1500 DC air volume up to about 1500 m³/h
• MAX 2000 DC air volume up to about 2000 m³/h
• upon request DC air volume up to about 8000 m³/h
• upon request AC air volume up to about 8000 m³/h (alternating current systems)
• The ventilation system LS300 is available with direct current (DC) fans, also called EC = electronically commutated

With regard to the systems LS 450, LS 600 and LS 800 a selection between DC and AC fans (alternating current) is possible depending on the required external pressure.

The exact dimensioning of the ventilation system for each object will be individually determined after in-depth consultation.
