Out phasing of dimethylformamide (DMF) and cobalt dichloride in piping production

By introduction of new production equipment, the pipe producing company Logstor, have been able to phase out dimethylformamide (DMF) as a cleaning solvent. Instead, most cleaning of mixing heads and sprayer heads is done mechanically, and in rare cases a Dowanol (1-methoxypropan-2-ol) bath is used. Cobalt dichloride containing silica gel desiccant have been substituted with a cobalt free desiccant, which is performing even better than the old one.
