Pure nitrogen generator GCHA-21D
from 276 000 ₽
Manufacturer:
NPP Himelektronika
Location:
Moscow
Applying:
An analogue of GCHA-21, but equipped with a built-in system of catalytic purification of the resulting nitrogen from hydrocarbons. GCHA-21D nitrogen generators are designed to produce nitrogen of the highest purity in laboratory conditions.

The warranty period of operation of the generator is 18 months from the date of sale by the manufacturer.
