Accessori meccanici

Whenever the maximum guarantee of continuity in case of a power outage is necessary, Visa offers an evolved compressed-air operated start system as an optional. The normal engine start system for a generating set is powered by lead-acid batteries; this reliable and consolidated solution requires batteries that are able to deliver strong peak currents during start-up. Such elevated instantaneous stress on batteries that are old, poorly charged or not periodically tested can cause them to break without warning; being able to rely on a start-up system that is based on a completely different and independent accumulation of energy offers the maximum guarantee for success. The pneumatic system is usually provided alongside the standard electric one.

Visa offers a solution with no compromises if a fuel pre-filtering system must be used due to low quality or the presence of contaminants. This consists of the Parker Racor Turbine series; which is a top of the range product of the leading Californian manufacturer in the fuel treatment sector. The Turbine filters are designed specifically for their application in industrial diesel motors; thanks to their special technology they can intercept solid contaminants such as dirt, rust, algae, tarry residues and paints, and can separate, stop and signal any traces of water in the diesel.

Applications that are subject to particular regulations that limit the amount of fuel in the machine or any application requiring greater autonomy than standard, Visa S.p.A. offers two systems that are able to automatically manage on board tank loading. The following elements are required to set up an automatic fuel loading system: external tank, booster tank, control system, automatic diesel level detection system in the booster tank, transfer system. Normally, to guarantee a greater standard of safety it is also necessary to install a solenoid valve on board the cistern that is able to stop the flow of diesel in case of emergency.

For applications that require the generating set to be moved quickly and frequently Visa proposes installation on trailers; various technical solutions will satisfy the most differing conditions of use. The range of trailers includes certifiable low speed tow trailer models for road use.
STRENGHTS:
-the machine can be easily handled without specific lifting systems
-the machine can be easily stocked during non-use periods and/or for maintenance operations
-possibility to assemble specific accessories to the trailer

To guarantee elevated operating autonomy Visa can provide various fuel storage solutions. Based on the type of installation it is possible to choose between a vast range of below and above ground cisterns. In all cases these products are manufactured entirely in Italy, with top quality materials and equipped with safety devices as required by the regulations in force.

Star

With star the start of each of the three phases is connected together. Connections are taken from the ends of the three phases to give the three phases
Star symbol voltage

Delta

With Delta the starts and ends of the phases are connected. The end of phase 1 is connected to the start of phase 2, the end of phase 2 to the start of phase 3, and the end of phase 3 to the start of phase 1. Connections are taken from the three start-end points to give the three phases.
