Designed as per the Single-Double effect technology, Thermax’s multi energy machines enable maximum heat recovery from both the heat sources. In a Double effect cycle high grade heat is used, while for a single effect cycle low grade heat is used. Most commonly used Multi energy machine is EJ Series i.e., using Engine exhaust and engine jacket water.
