2/3CHP units for heat and powerTailor-made energy concepts for the provision of heat and power.Combined heat and power modules(CHP modules) are compact energygeneration units that provide a de-centralised(local) supply of heat and power with aconsumer focus at an overall efficiency ofaround 90 %. Compared with a separateenergy supply with power from a condensingpower plant and heat from a boiler, primaryenergy savings of well over 30 % can beachieved. This is also linked to acorresponding reduction in pollution.Depending on the fuel comparison, thismeans the emission of up to 25 % lessnitrogen oxide (acid rain) and around 60%less carbon dioxide (greenhouse gas).CHP modules are primarily used to coverthe heating base load and are complementedby peak load boilers. The generated power isused to cover own demand, whenever thisis economical. However, in principle, acombined heat and power module meansthat there should be no power generationwithout heat consumption. And withoutpower generation, there is no amortisationof investment and operating costs, whichwould therefore not be economical. Theparallel generation of heat and powerrequires a simultaneous consumption ofheat and power.An internal combustion engine is suppliedwith natural gas and combustion air from theinstallation room. This energy is convertedinto mechanical energy by the engine.A synchronous generator is powered via thecoupling. This generates 400 V and 50 Hzthree-phase current.Via the integral control system, the generatedcurrent is routed in accordance with therelevant protection regulations to the on-sitemain distribution board. The waste heat fromthe engine oil, the engine coolant and theexhaust gas, is collected in the "internalcooling circuit" and made available to theheating system at a flow temperature of up to90 °C.At the core of the CHP unitlies the gas engine.CHP units for the combined generation of heat and powerwith an output range from 5 to 401 kW el

4/5When and where is the use ofCHP beneficial?The use of energy efficient engines makes CHP a powerful and high efficiency unit.CHP unit viabilityWith the standard manufacture of CHP unitspowered by natural gas or biogas, Viessmannextends its comprehensive product range forapplications requiring a medium output inmunicipal buildings and industrial andcommercial enterprises. To ensure theeconomic viability of a CHP project operatedwith natural gas, it is recommended that theoutput is precisely matched to the heat andpower demand.CHP unit also with condensing technologyThe Vitobloc 200, module EM-20/39, used incombination with a peak load boiler is idealfor residential complexes from 30 to 50 units,for medium-sized hotels, care homes andbusiness showrooms, etc. With an overallefficiency of 94.9%, the CHP unit operateshighly efficiently thanks to its condensingtechnology and is recommended both for newbuild and modernisation projects.Operation in parallel mains andemergency power modeAll modules can be operated in parallel mainsmode and optionally also in emergency powermode. This means that, in the event of a powergrid failure, the Vitobloc 200 can supply theunit with power after a short start-up time.Benefits at a glancen High electrical efficiency through the useof energy efficient engines, resulting inthe highest possible power bias formaximum economyn All Vitobloc 200 units are capableof modulationn Standard equipment level includes startingbatteries and a synchronous generator. Asa result, the CHP unit is equipped formains substitution operation with noincrease in the idle current demandn Also suitable for demanding connectionconditions, e.g. the cos I can be regulatedn Can be operated with natural gas, biogas,sewer and landfill gasn Time and cost savings during engineering,installation, commissioning and operationthrough generous standard equipment leveln Longer service intervals through integrallubricating oil supply with optimised tankvolume. Operating costs and idle times arereduced, as a resultn Factory tested units ready for installation;therefore minimum installation effort andtested output valuesn Proven technology, with more than 750installed systems worldwiden Proven remote monitoring and automationsystemsn Extensive service offer, e.g. differentservice options – from standard to fullserviceThe Vitobloc 200 is characterised by its compact design.

The utilisation of this heat, e.g. forheating buildings, reduces heat losses andlowers emissions that are damaging to theenvironment. Combined heat and powergeneration enables up to 36% of primaryenergy to be saved and is therefore one ofthe most efficient energy-saving methodsavailable today.

8/9Comprehensive service for every system –from engineering to maintenanceFrom control panel to maintenance contracts, ESS offers a comprehensive range ofservices for all CHP units.Tailor-made control panels withestablished softwareSince 1983, ESS has been offering tailormadecontrol panels and matching softwarefor PLC, automation, network coupling,auxiliary drives, control units and power units.The company can draw on extensiveexperience to deliver bespoke solutions,especially when it comes to modernisingexisting CHP systems. Smaller domesticcontrol systems with optional remotemonitoring can also be supplied.Commissioning and handoverPrior to despatch, each individual CHP unit issubjected to extensive tests on the in-housetest bed. As part of these tests, specifiedoutput values for the unit are documented,keeping the effort when commissioningthe system at the customer's premises toa minimum. ESS hands over these units fullytested and ready for use.There are service contracts 100/200/300100: Maintenance contract incl. labour costs,wages and travelling expenses. Optionally with/without lubricants.200: Scope of maintenance contract100 plus repair in line with maintenanceschedule and basic repairs. Optionally with/without lubricants.300: Scope of maintenance contracts 100,200, lubricants and troubleshooting, as wellas implementation of unscheduled repairs.Optionally with unscheduled repair parts.This constitutes an extended warranty.Each customer can assemble their ownindividual service package from severaloptions according to their individual demandsand requirements. This includes everythingfrom commissioning and training, to completeoperational management.Maintenance contractsDifferent maintenance contracts offer manyoptions, allowing a flexible personalisedcontract to be found. A number of contractoptions are specifically tailored to public bodies.Intensive test runs prior to deliveryare, naturally, a must.
