Product Information

Single fluid for both cooling and lubrication, the GSL series is one of the best choices to work for continuous duty in severe hot weather conditions such as in tropical areas. Available both in an open and soundproof version, these generating sets are highly appreciated in the telecommunications, construction and defence sectors due to their durability and reliability.

Great performance from these oil cooled engine generators, offering reliable power with easy installation. The GSL series are perfect for locations not connected to a main power supply.

Extra Information

The Load Transfer Switch (LTS) panel operates the power supply change over between the generator and the Mains in backup applications, guarantying the feedingto the load within a short period of time.It consists of a standalone cabinet which can be installed separate from the generatingset. The logic control of the power supply changeover is operated by means of theAutomatic Control panel mounted on the generating set, so therefore none logicdevice is required on the LTS panel.
