Temptek Tuff- Tank 800 gallon for Plastic Manufacturing Chilling - for repair

We are a chiller and chiller system provider. We purchased this for a local project several years ago, and spent much time insulating it. On start up a small leak was discovered in the center on the bottom. We removed and replaced. Some insulation removed while diagnosing leak. It is relatively small crack would need repair, best way might be a bolted plate with gasket. We need the space back.

We will strap to the pallet it's on but freight is extra.
