NH3 Compressor

Hi

I am looking for NH3 compressor with 20 M3/h displacement .

I am thinking to use IIV Bitzer open type compressor with changing O ring in shaft seals .

Any idea will help me .

mbc,
Not sure on Bitzer, but Bock make something for ammonia.
Usually need water cooled heads

mbc , RANGER1 , Bitzer also made NH3 comp.
For example open type W2TA-S230 or S250.
About Bock , I saw that they have problem with loosing too much oil with original oil separator.
That 2 compressors was installed by some other company and they put one more oil separator.
For Bitzer I dont know , I use them only in ***** installation.
