This new product platform has been developed for premix condensing gas boilers and other gas appliances. Advanced design and engineering tools such as FEM (Finite Element Method), CFD (Computational Fluid Dynamics), DOE (Design Of Experiments) testing routines, and Design for Assembly principles were used in developing this product.
NG40 main features are: 
@ Compactness – Blower Dimensions are the most compact among premix fans available in the market in its class. 
@ High “pressure vs. volume” characteristics provided while overall blower efficiency maintained above average industry levels 
@ Wide modulation ratio up to 10:1 can be achieved with use of SIT developed electronics 
@ Flexibility for various applications - The blower electronics is equipped with a programmable microcontroller managing several functional curves and as such the NG40 can be easily fitted to a wide range of applications. 
@ NG40 has 5 patented technical solutions related to impeller and scroll case flow dynamics, electric motor construction (coupling compactness and simplicity), programmable electronics.
 

Three principal models are available:
- Controlled by 230 V AC electronic board
- Controlled by 24 V DC electronic board
- Without electronic board, with hall sensor only.
