We are offering here the Dry Ice Blocks that serve as excellent refrigeration for food processing and transportation applications. Dry ice removes almost twice as much heat per pound as water ice. It changes directly from a solid to a gas without becoming a liquid, thus, eliminating clean-up. Blocks are generally used for larger frozen transport shipments, camping and fishing trips or when power (hydro) has been lost (blocks can be used to keep the contents of walk-in freezers and residential chest freezers from thawing). The dry ice blocks are made for use in the various industries.
