Product Description:

Vokes® NPP (Nanoporous insulation panels)


Vokes® NPP is an evacuated micro porous thermal

insulating panel with excellent insulating properties.

Vokes® NPP 

The core material of

Vokes® NPP is fumed Silica board and noncombustible.

It is sealed into a high gas barrier film under vacuum.

Vokes® NPP 


Vokes® NPP is specially developed for insulation

applications where not much space is available but a

high thermal resistance is necessary. Mainly used in

high-temperature insulationMainly used in hightemperature


Vokes® NPP 

Vokes® NPP is a successful insulation element in the following areas:

• Industrial equipment insulation 

• High temperature boiler insulation 

• Thermal packaging (Medicine transport boxes, etc.)

• Appliance (Water boiler, etc.)

• Automotive (train, ship, air plains, etc.)


• Insulation : Long-term application temperature reached -120℃-1200℃. Insulation at normal

temperature for 3-5 times the performance of traditional materials. Stable thermal conductivity at high

temperatures, Temperature at 300 ℃ insulation performance is 4-8 times that of traditional materials.

• Drastically reduced insulation thickness 

• Thermal resistance :Particles constituting unit having a three-dimensional network structure,

will form many nanoporosity avoid sintering deformation.

• All purpose VIP with a long service life 

•Corrosion resistant :Products made of an inorganic material, no soluble chloride ions, No

corrosion on equipment, pipe grassroots.

• Soundproofing/Seismic Performance :Acoustic noise reduction, buffer shock.

• Waterproof :Product nanoparticles themselves with super hydrophobic properties.

Q:How to maintain the blower
4, the use of adjustment device will always maintain a uniform tension Tension state, not too loose or too tight.
Q:The relationship between fan power and air flow
Air volume is the total volume of air sent or sucked into the air-cooled radiator fan every minute. If the unit is CFM, the unit is CFM. If the cubic meter is the CMM, the air volume unit used in the radiator product is CFM.
Q:Boiler feed pump and the difference between ordinary pumps
The pulsating force is accompanied by severe noise and severe vibrations.
Q:How are the fans classified? Can be divided into several categories?
Fan classification can be divided into centrifugal, axial, oblique flow (mixed flow) and cross flow type according to the direction of gas flow.
Q:What are the uses of the blower?
In the operation of the use of blower pressure difference will automatically lubricate to the drip nozzle, drip into the cylinder to reduce friction and noise, while maintaining the cylinder gas does not return, such a blower, also known as the vane blower.
Q:It is good for coal - fired boiler
First fan needs wear-resistant structure and easy to scale the impeller - radial impeller
Q:What is the difference between a high-pressure ring fan and a Roots blower?
The air between the impeller blades is spirally accelerated and the gas outside the pump body is squeezed into the side slot (when sucked into the side of the suction port). When it enters the side channel, the gas is compressed and then reverts between the impeller blades
Q:Difference between air compressor and blower
Air compressor: usually used as a pneumatic machine or appliance power source, the general pressure is high, up to 5kg / cm2 - 105kg / cm2.
Q:What is the difference between the ventilator and the draft fan (G and Y)?
Its resistance to grain erosion and wear performance at least ordinary tungsten carbide surfacing, spray spray welding and alloy powder welding and other conventional treatment methods to improve more than 5 times higher than the matrix 16Mn steel more than 100 times; thickness of 1.5mm ceramic actually use
Q:Usually the fan can be divided into several types
The fan is a mechanical fluid that relies on the input of mechanical energy, which increases the gas pressure and sends the gas to the gas. It is a driven fluid machine.
