ZT GAS MIXER GAS WGM15/25/50/75/100-2 FLX

Detail

Parameters

The ZT GAS mixing ratio system is suitable for a variety of Industrial gas technology applications.Designed for low maintenance and ease of operation.

Advance mixing ratio technology, without the need for a buffer tank or power supply.

Advantage

l The mixing accuracy is not affected by changes in gas consumption (within the applicable range)
l Automatic stop mixing function: If one of the gas sources interrupts the gas supply, the mixer will automatically stop working
l Adopting a stainless steel casing, it can be installed outdoors and adjustment is inside the casing to prevent unauthorized adjustment.

Benefits

l High mixing accuracy
l avoids the need to stock multiple pre-mixes
l does not require receiver
l inlet gas filters protect the device against impurities
l pneumatic operating principle, no electrical required
l mixed gas production from 3 l/min to the max. flow
l robust, compact design
l Panel mount for wall mounting
l minimal maintenance required

Option

Optional Remote monitoring function
built-in inlet pressure alarm module
digital pressure display (when using analog pressure transmitter)
alarm monitoring with parameter setting
Historical data monitoring
Remote monitoring through mobile Apps

Easy operation:

a mixing valve with a control knob and %-scale provides infinitely variable mixture settings (FLEX)

Note: The determined data of mixture output are only in relation to N2!

The use of other required gases results in a difference to the mixture output, which is compensated by the

correction factor F_MIX.
