Continuous SSP Nitrogen Purification Unit（WSNPU）
Dedicated nitrogen purification unit for continuous SSP
WELLSUN Continuous SSP Nitrogen Purification Unit（WSNPU）consists of molecular sieve adsorption tower, regeneration system and electrical control system PLC (DCS or FCS ). It can be equipped with two-tower type or three-tower type of adsorption tower in accordance with the requirements of products and consumers.
It adopts advanced process technology designs and various fuzzy logic programs to make sure the nitrogen output has stable dew point and is reliable.
It is equipped with specialized desorption unit for small molecules removal, so the molecular sieve will not be contaminated. The expected life of molecular sieve is more than ten years.
Advanced Human-Machine Interface（MMI/HMI）：Operating easily and saving manpower.
The unit is configured with special energy economizer. Compared to congeneric products, save one-third of the energy in general.
Capacity: 500 m3/hr ~5000m3/hr
Nitrogen dew point: the minimum can reach to -80℃
