GENSET DESIGN


Trends in the genset market: - a rental sector focus


Generally speaking, the genset rental sector is being strongly driven in particular by considerations such as noise pollution, engine efficiency, and gas emissions, as well as the need for an increase in energy output. This is the conclusion of a recent report by INMESOL which also looks at issues such as low sound emissions, low gas emissions, and remote monitoring, reports UKPN.


A


significant portion of the growing genset market - mainly the rental machinery sector - incorporates companies which organise shows,


events, and promotions, food and beverages, catering and hospitality services, etc. An INMESOL spokesman told UKPN:


“These types of clients are demanding equipment with low gas emissions regulated by strict and limiting regulations, equipment controlled at all times, and equipment with maximum reliability in terms of service provisioning. They are also seeking increas- ingly quieter gensets. “The reduction of noise emissions has been


one of the main objectives set by INMESOL for developing new products launched in 2017.” The INMESOL R&D Department has worked hard, establishing elaborate studies and making numerous tests on different prototypes. A design with optimum airflow and that includes a good sound trap system (sound absorbing elements) has finally been developed. In the new equipment the approximate decrease in the perception of the genset’s sound emission is between 15 and 20%.


All INMESOL rental range generator set models already include the new design. In addition to being robust gensets which offer all the features required by the sector, they are now quieter. The regulations on gas emissions that


affect internal combustion engines are increasingly demanding and have more restrictive limitations. Engine manufacturers keep on trying to adapt the design of their engines to comply with the regulations and, as a consequence, they are developing efficient engines with advanced control systems and with gas emissions below the limitations established. In European legislation, STAGES I, II, IIIA, IIIB and IV determine the amounts of the following pollutants which are permitted, based on the number of grams per kilowatt- hour of the compounds present in diesel exhaust. * NOx Nitrogen Oxides: NOx is a combustion byproduct which combines in the atmosphere to create ozone, acid rain and smog. * HC Hydrocarbons: Essentially unburned


fuel, HC contributes to ozone and smog production. HC is a minor constituent in diesel exhaust.


“Cl ients are demanding equipment with low gas emissions regulated by strict and l imiting regulations, equipment controlled at all times, and equipment with


maximum


rel iabil ity in terms of service


provisioning. They are also seeking


increasingly quieter gensets.”

*.CO Carbon Monoxide: CO is also a minor constituent of diesel exhaust. It is controlled by improving combustion efficiency. * Particulates: Particulates are made up of


soot particles in diesel exhaust from unburned carbon. Particulate matter is controlled by optimising the combustion temperature and improving combustion efficiency. Generating sets with diesel engine from 18


to 560kVA are required to meet stage IIIA requirements, with the exception of generators for fixed installations and emergency generators (STAGE II) within the European Union. INMESOL always works with prestigious manufacturing brands, capable of supplying engines that meet the latest emission requirements established by the correspond- ing regulations, in particular, those on the gas emissions, which is currently STAGE IIIA in Europe. Another feature in demand by the rental


sector is the remote monitoring of the genset status. The GPS devices installed on the generator set now make it possible to remotely control, monitor, and locate the equipment in real time. Thus, the generator set status, alarms, consumption, and fuel level can be checked from any device (computer, tablet, or mobile phone), at any time, from anywhere. This helps minimise maintenance costs and visits to the place of use. A further advantage is the real time motion


alert warning, which makes it possible to prevent and act quickly in the event of machinery theft. www.inmesol.com
