WASHINGTON, June 26 (Reuters) - Hudson Technologies Inc (HDSN.O: Quote, Profile, Research) filed on Thursday to periodically sell up to $30 million in debt securities, common and preferred stock, warrants, and units.

The refrigerant services company said in a filing with the U.S. Securities and Exchange Commission it will use the proceeds from the offering for working capital, general corporate purposes, or acquisitions.

Under a shelf registration, a company may sell securities in one or more separate offerings with the size, price and terms to be determined at the time of sale. (Reporting by Karey Wutkowski; Editing by Andre Grenon)
