Edwards IQ Dry Vacuum Pumps are well-suited for vacuum applications in solar cell manufacturing. Like integrated circuit and flat-panel display manufacturing, solar cell manufacturing depends on a variety of vacuum-based processes, from PECVD (plasma-enhanced chemical vapor deposition) silicon deposition to lamination of the finished module. High pumping speeds and rapid chamber cycling are essential if these processes are to meet the throughput requirements of the solar cell industry. Our rebuilt Edwards IQDP Dry Vacuum Pumps are dependable with benefits that include very lower up front costs, reduced energy consumption and decreased maintenance requirements.

Please be aware this equipment is located in Brazil.
Brazilian laws for imports and exports are very specific and different from all other countries in South America. It’s therefore important to understand Brazil’s export regulations/policies to move goods across borders.
EquipNet’s Brazilian sellers never export equipment by themselves, which means they do not conduct transactions/business with foreign companies, only with Brazilian legal entities.
International buyers are responsible for hiring, by their own expenses, a trading company. This trading company is a Brazilian legal entity, duly registered with CNPJ (National Registry of Legal Entities) and RADAR (Registry and records of customs and customs-related agents).
The trading company legal entity will acquire the equipment from the Brazilian seller, pay the seller in local currency, and receive the related invoice from the seller in the name of their Brazilian legal entity. After this process, the ownership will then be transferred to the trading company who will be responsible for export and assistance during the customs clearance process.
The international freight quote is also necessary for the transaction process. EquipNet is happy to provide support throughout this process. Please contact sales for more information.
