Performance of our parts

How do your parts compare to OEM ?

We pay particular attention to ensuring that the compressed air parts we supply have been internally tested and meet our quality standards. 

OEM (Original Equipment Manufacture ) can be confusing because the spare parts that a compressor manufacturer sells could have been produced by a third party and re branded to appear to be manufactured by the compressor supplier.

In many cases (take oil as an example ) the compressor manufacturer does not refine the oil they sell, they merely re brand the oil from other suppliers to appear like it was produced by the compressor manufacturer.

Ztechnique are very open about our 're branding' of our suppliers spare parts and often seek the same parts to re brand (Siemens contactors for example) but at lower re sale cost than the OEM,s

Which oil free air ends do we produce ?

Whos air ends do you replicate ?

We currently produce NON OEM air ends for Atlas Copco and equipment using GHH air ends like Ingersoll Rand for example.

We can refurbish your own elements you free issue to Ztechnique or we can supply you with new Ztechnique elements for these compressors.

In 2020 we can offer you NEW and refurbished GHH air ends from the OEM and alternative suppliers 

 

Are refurbished as good as new Elements ?

No you will never get the exact same performance as a new oil free element from a refurbished air end.

The normal difference is between 5 to 10% less efficiency due to re use of the key components .

Where new rotors are installed on refurbished element's from Atlas Copco and GHH compressors the efficiency increases to between 3% to 5%

Whilst many customers prefer refurbished instead of the cost of new elements the small loss of efficiency is agreeable when compared to OEM new prices. for more information about our air ends click here 

Can we buy new Ztechnique elements from you ?

Yes we have a range of new Ztechnique elements for Atlas Copco and GHH fitted equipment.

The price is considerably less than New OEM prices and the efficiency is within 1/2%  efficiency claims the OEM makes for its products.

Each air end is supplied with a test certificate showing the test has been carried out at our Merseyside test facility for 2 hours duration

Are your elements oil free ?

Yes exactly as the manufacturer states the design of the Ztechnique elements mirrors the OEM design by not allowing any oil to enter the compression chamber. 

Any oil passing the internal seals is sent down 'vent holes' to atmosphere and cannot contaminate the customers product.

Our design of our air and oil  seals has been proven to be as efficient as the design allows for sealing efficiency and promotes long life when paired with our proven coating material 

Is your rotor coating as good as the OEM material ?

We have worked very closely over many years with our coating provider.

Our coating has proven to work better in harsh environment's that the OEM choice of coating.

Our coating has a higher temperature threshold than some OEM,s and it has nil silicone or Teflon present making it suitable for the tobacco and vehicle industry.

Our coating is not a 'sacrificial' coating as some OEM,s prefer. Our coating is hand applied to very strict quality procedures.

 

NON OEM MD Dryer Rotors

Is Ztechnique MD Rotor Material Hard wearing

We use a high quality silica rotor material sourced in Europe. 

The life expectancy of an MD dryer rotor is 40,000 to 50,000 hours in good running conditions.

Rotor life can be affected by poor maintenance scheduling , frequent load , unload patterns , poor dryer tuning and lower than recommended regen temperatures.

For more information and warranty explanation pertaining to MD dryer parts please contact us 

 

Replacement Coolers

Are your ZR ZH coolers comparable quality to the OEM

Our coolers for Atlas Copco ZA ZR ZH equipment are our own Ztechnique brand.

The selection of cooler materials is very important to the longevity of the coolers.

Our coolers are plug and play with the original cooler housings.

We also supply a range of cooler install kits for ZA ZR ZH replacement coolers.

Our standard warranty on our coolers is 12 months from date of installation.

Warranty claims may subject to water quality inspections and use only  on closed circuit cooling systems.

Do you supply coolers for Ingersoll Rand Centac models

Yes we supply a full alternative cooler range for Ingersoll Rand Centac turbo compressors.

The quality of our coolers is very high and sourced in Europe.

Warranty is 12 months from the date of install subject of course to water quality conditions on site. Warranty claims may be subject to water quality testing.

If you need specific details of our products you can email a representative by going to our contact page
