50 and 70 Kilowatt Combined Heat and Power Gensets |
50 Kilowatt Genset Installed Download Product Specification Sheets The engine-driven DGPS Model 50 and DGPS Model 70 Cogeneration Systems can effectively reduce power bills by co-generating combined heat and power (CHP) on site. Heat is captured from the hot water produced by the engine. The combination of electrical and thermal savings can amount to 20-40% of the power bill. Net metering, where permitted, can further increase savings. Multiple gensets, if called for by the buildings’ load profile, can be installed in parallel and brought on line as needed and can be operated in either base loading or peak shaving mode. DGPS incorporates proven engine and fuel technologies in its reliable, maintenance-friendly naturally-aspirated, reciprocating engines. These engines are powered by clean burning natural gas and turn Lincoln induction motors to create all or a portion of the facility’s electricity on site. The utility’s power grid is there to provide the rest. Optional sound attenuating insulation can reduce sound levels to 70 decibels. The high compression, high performance engine system is built by DGPS to deliver peak fuel efficiency, enhanced thermal output and long life through proprietary components including inverted Venturi carburetors, low-lift cam shafts and air-gap intake manifolds as well as specially modified heads and pistons. The solid state, crank fire ignition system eliminates distributors and their associated maintenance. A base level of 300,000 BTU’s per hour of heat can be captured from the engine’s wet manifolds and exhaust heat exchangers. Recovered heat can be used to drive building heating and cooling systems. Combined heat and power cogeneration dramatically increases return on investment and shortens payback periods. Natural gas emissions from this equipment meet state and local requirements with the addition of catalytic converters. The DGPS modular controls are intelligent, configurable and enable scalable solutions. The system monitors and controls all genset operations through proprietary protocols that are capable of running in a load following and/or constant output mode. Programmable options include setting up to two operating time windows daily when power and thermal efficiencies are optimized. The system will handle from one to nine Model 50 gensets simultaneously. The control system can be programmed and monitored – or alarms received – at the genset, via wired on-site remote panels or remotely over either dial-up or Ethernet connections. Critical functions that are monitored include over/under voltage, over/under current, reverse current, over/under frequency, over revolution protection, low oil pressure, engine temperature and oxygen levels in the exhaust as well as intake and outlet water temperatures and flows for heat rate calculations. The two-step threshold alarm system responds to adverse readings by sending an alarm above the low threshold and under the high threshold, then shutting down the machine when above the high threshold. The DGPS Model 50 and Model 70 gensets are the perfect solution for projects under one-half megawatt. Ideal applications include apartment buildings and hotels, nursing and retirement homes, restaurants, schools and YMCA’s and other commercial, institutional, small industrial and military applications.
