Hi-Tech Cryogenic Oxygen/Nitrogen Plants is designed and built to the highest standards of reliability and efficiency to meet the most severe operating conditions. Each plant is assembled completely, thoroughly inspected and tested for performance under actual operating conditions to assure the highest level of quality. The modular design of the HTO Series plant minimizes transportation and handling expense and enables rapid on-site installation. Packaged for shipment in two 40’ ISO containers, the plant can normally be installed and commissioned within two days, requiring only a simple foundation. On-site plants make the constant supply of nitrogen or oxygen less reliant on delivered liquid. Proven cryogenic technology combined with a robust control system makes our plants a source of reliable gas supply.
