    S5 Range - Generator sets with Stage V engines

    The new S5 generator sets incorporate all manner of design and innovation features that make it one of the most technologically advanced and competitive products in the European rental market.



    A few years ago, the European Union set itself the main goal of limiting emissions of gaseous and particulate pollutants to improve air and pollution levels. Since the beginning of 2019, Europe began to apply the 2016/1628/CE regulation, which has forced all rental companies operating in Europe to renovate their fleet by incorporating equipment with Stage V engines. Generators that help to respect the environment by significantly reducing substances such as nitrogen oxides (NOx), carbon monoxide (CO), hydrocarbons (HC), particulate matter (PM) and particle number (PN) control.  


    STAGE V: EU Regulation 2016/1628, which regulates the emission limits for gaseous and particulate pollutants for internal combustion engines installed in non-road mobile machinery (NRMM). 

    RoHS2: Directive 2011/65/EU, which establishes restrictions on the use of hazardous substances in electrical and electronic equipment (EEE); designed for use with a rated voltage not exceeding 1000 volts for alternating current, and 1500 volts for direct current. An additional 5-year extension of the application of the directive has been set in place, from 22 July 2019, for lead in solders, and for bearings and pistons used in certain internal combustion engines.


    Stage V & RoHS2

    As a leader in the power generation sector and committed as we are to doing all we can to respect the environment, HIMOINSA offers a complete range of diesel and gas powered generator sets and lighting towers with Stage V engines.

    In addition, to reduce the use of polluting substances in electrical or electronic equipment in the European market, our generators comply with RoHS2, Directive 2011/65/EU.

    HIMOINSA has designed generator sets with Yanmar, FPT and Scania engines that include a new after-treatment system to guarantee an emissions reduction that is in compliance with EU Regulation 2016/1628 for non-road mobile machinery (NRMM). This has implied a qualitative leap that ensures a reduction of up to 90% of emissions of harmful components with respect to the previous technology.

    Guaranteeing a wide power range of from 9 to 550 KVA in P.R.P., the S5 range has been designed taking into account such factors as maintenance, durability, fuel consumption, and the final cost of the machine to make it one of the most competitive products in the rental sector in Europe. One of the main components of the S5 generator sets is their control units, meticulously designed to ensure a secure and efficient coordination with the control units of the new Stage V engines.

    These are compact generator sets that integrate all emission reduction systems and AdBlue’s tank in a robust and functional canopy. The new range incorporates a heavy-duty chassis whose pull skid has been reinforced and also includes protections at the accesses for forklift. The drip tray is designed to withstand 100% of the engine liquids.

    Optimization of maintenance and running costs

    S5 generator sets, primarily those with power greater than 80 kVA, guarantee running costs lower than those of generator sets with Stage IIIA engines, mainly due to a significant reduction of fuel consumption. Most S5 models incorporate a new after-treatment system for gases that require a greater investment in filters 

     and spare parts for new components. However, the fuel consumption of the new engine is significantly lower, which ensures lower operating costs than generator sets with Stage IIIA engines. In parallel, HIMOINSA has made the fuel tanks of their S5 generator sets the same size as the AdBlue tank to match their fuel and urea running

    time, thereby reducing running tasks and costs. The HRFW 200 S5 model that is being presented at Bauma, incorporates a fuel tank with a capacity of 600L with a running time of 14 hours. The consumption of urea in an S5 genset is roughly 10% of the fuel consumption.

    In order to reduce noise emissions even further, S5 generator sets incorporate a special rock wool insulation. Components of different densities and characteristics are used at the air inlets to reduce noise in a broad spectrum of frequencies. The location and layout of the air inlets have also been optimized to mitigate noise.

    The S5 range includes a new control and power panel at the rear of the canopy which affords several competitive advantages: 

    • It minimizes noise emissions. The panel is isolated from the engine room so there is no exposure to noise while the control unit is being handled.
    • It facilitates maintenance. The panels can be replaced without having to remove the canopy.
    • Accessibility and reduction of space. The usual power outlet is replaced by a lower one that limits the total footprint of the genset and improves access when any kind of manipulation is required.
    • To ensure easy transportation. The new design has optimized the location of the lifting points; the single point is replaced by two side plates with different points distributed longitudinally to stabilize the lifting of the genset. In addition, the drawbar and the forklift accesses have been retained

    To ensure the highest levels of impermeability new doors have been designed whose upper face is angled at 20 degrees. This prevents water filtration and oxidation points caused by an accumulation of stagnant water. The canopies of the S5 generator sets retain the rest of the components that have been added to the other ranges to withstand heavy rains and snowfall.

    HIMOINSA has incorporated a new layer in the process it follows to paint and protect metal parts. This involves a zinc-rich primer prior to the final finish ensuring a best-in-class canopy. As they are made in stainless steel, all the door locks and hinges of this new range are more resistant.

    To ease the access for maintenance purposes, the S5 Range incorporates:

    • A hinged door that provides access to the after-treatment system for maintenance, and to the radiator for cleaning.
    • Wider doors to ensure better access to all the engine and alternator components for correct maintenance and for the replacement of consumables. 
    • Maintenance intervals of 500 hours.
    • Drain valves to make it easier to clean the radiator. S5 generator sets with FPT and Scania engines include low coolant level sensors that provide an additional point of control to prevent overheating before it occurs, thereby lengthening the life of the engine.
    • Internal fuel filling tank to prevent theft and accidental spillage of fuel during loading.

    What is the After Treatment System?

     01. Exhaust Gas.  After an efficient diesel combustion thanks to an electronically controlled engine and a common rail injection system, the exhaust gas comes out of the engine as yet untreated but already with reduced emission levels.

    02. DOC | Diesel Oxidation Catalytic. The DOC reduces the amount of CO and increases the percentage of NO2 entering the SCR which speeds up the process that turns NOx into harmless nitrogen and water.

    03. Adblue Tank. The approximate consumption of AdBlue tank is about 10% of the diesel oil consumption. The concentration of AdBlue is 32.5% urea, the rest is water. The urea tank is heated to prevent the urea from freezing.

    04. Mixer. It contributes to the process of creating ammonia from the reducer (AdBlue). The mixer consists of an injector where the AdBlue enters the exhaust system.

    05. DPF | Diesel Particulate Filter. A filter that prevents the output of unburnt diesel particulate matter and ashes. Eliminating this particulate matter benefits emissions and reduces diesel consumption.

    06. SCR | Selective Catalyst Reactor. Emissions control technology that converts nitrogen oxide (NOx) into molecular nitrogen (N2) and water (H2O) through the use of a catalyst and a gaseous reducer.

    07. Exhaust Outlet. The exhaust gas is monitored by the ECU throughout the entire emission reduction process thereby allowing our generator sets to comply with Euro Stage V emission levels under all working conditions.

    01. DPF – Regeneration Assist Device (intake throtte valve). Engine temperature is increased by using an inlet valve.

    02. EGR – Exhaust Gas Re-circulation. Redirects part of the exhaust gases into the combustion chamber to ensure they are burnt better, thus reducing the amount of NOx.

    03. Common Rail Electronic Injection. Provides more effcient combustion reducing the amount of unburnt diesel and NOx particulate matter.

    04. After Treatment Pack.

    ADOC –Diesel oxidation catalytic.

    BDPF – Diesel particulate filter.
