MTU ONSITE ENERGY GENERATOR SETS ARE AVAILABLE WITH SKID-MOUNTED OR REMOTE RADIATOR OPTIONS.
Factory-supplied cooling systems are prototype tested to ensure that cooling and design performance requirements are met. Curtis Engine can also supply additional equipment and accessories to integrate the generator set into remote cooling systems such as heat exchangers or cooling towers. Careful consideration must be given to cooling and ventilation requirements of the generator set when designing remote radiator and heat exchanger systems.
Remote radiator systems are often used when there is insufficient ventilation air in a room or enclosure to properly cool the generator set.
- Engine or skid mounted radiators are generally considered to be the most reliable and lowest cost cooling system
- Remote radiators are available in horizontal or vertical configurations
- Remote radiator systems require longer pipe and control wire runs, pumps, fans, motors, and large amounts of coolant
- Remote radiator systems also require significant design and installation work to be performed
Some applications may also require a fuel or oil cooler to be installed in conjunction with the engine cooling system. Fuel coolers cool the unused fuel that is returned from the engine.
Per NFPA 110, engine heaters are required on emergency standby generator sets used in life safety applications to help ensure cold engine starting.
- Engine heaters are designed to pre-heat diesel and gas engine generator sets
- Require a permanent AC power source and come in various voltages to match the facility’s electrical service
- Engine heaters are also known as block heaters, jacket water heaters, or coolant heaters
Co-generation or combined heat and power (CHP) systems use heat exchangers and exhaust heat recovery systems to cool the engine and transfer the heat to create hot water or steam for use elsewhere in the facility.
- Electricity can be used onsite or fed onto the grid
- Thermal energy from the engine exhaust and jacket water can be converted to process heat, steam, or hot water
- Using an absorption chiller, CHP systems can also create cooling energy with their waste heat
Curtis Engine can help design, build, operate and maintain co-generation/CHP systems using MTU Onsite Energy gas generator sets as the prime mover and integrate the balance of plant components to create a turn-key system.
