OPRA Turbines is pleased to announce it has opened a new facility in Hengelo, The Netherlands to further strengthen and increase production capacity following recent growth in business. The new facility of (4,000m2) is located at Haaksbergerstraat 71, 7554 PA Hengelo, The Netherlands and will replace the existing facility located at Opaalstraat 60, 7554 TS Hengelo, The Netherlands. It is located in the High Tech Systems Park (HTSP), a newly developed industrial park providing an attractive environment for innovative high tech companies. The new OPRA Turbines headquarters boasts a state of the art production facility with natural gas pipeline access; suitable for R&D, assembly and gas turbine package and engine testing.







OPRA Turbines is pleased to announce the development project "Ultra-low emission gas turbine combustor" made possible with subsidies from the European Union. The subsidy project is for the development of a prototype of the next generation low-emission combustor for the OP16 gas turbine. The subsidy comes from the Europees Fonds voor Regionale Ontwikkeling (EFRO) as part of the "Operationeel Programma Oost-Nederland".






In June 2014 OPRA announced the successful development of a new product, the OP16-3C gas turbine.


The OP16-3C has the same engine core as the well-proven OP16-3A/B gas turbines and has the same power rating (1.85 MWe). However, the OP16-3C features a new combustor specifically designed to burn ultra-low calorific gaseous and liquid fuels. A wide range of fuels can be utilized including, but not limited to, waste gas, syngas, biogas, coal derived gas, pyrolysis oil and ethanol.

The OP16-3C can run on fuels with heating values as low as 10MJ/kg and under certain conditions fuel with even lower heating values. The combustor has been tested on several fuels including pyrolysis oil and syngas with a heating value of 6 MJ/kg. It can operate in dual fuel mode with a high-calorific fuel (liquid or gas) as a back-up fuel, and in bi-fuel mode where a supplementary fuel can be used to boost an ultra lean fuel.


'The OP16-3C will widen the market for OPRA considerably, enabling OPRA to further enter the waste to energy market as well as cater for the growing demand of alternative and often times challenging fuels within industrial combined heat and power (CHP) and remote oil and gas fields. The ability to run on these ultra-low calorific value fuels is revolutionary and unique compared to other gas turbines currently available on the market'. Regine Mowill (Marketing Director, OPRA Turbines)





In July 2014 OPRA announced it will supply an OP16 gas turbine powered generating set which will operate in CHP (combined heat and power) mode to BASF in Germany. BASF is the world's largest chemical company by yearly turnover, producing more than 9000 raw and semi-finished chemical materials with customers in over 200 countries.


BASF will upgrade their facility in Germany with a reliable and efficient cogeneration system replacing an existing boiler. As an environmentally friendly source of heat and power, CHP increases security of supply and enables highly efficient generation of heat and power, while at the same time providing cost savings.


The BASF production-plant produces food supplements such as emulsifiers and has a 24 hour operation regime. The OP16-3B will provide approximately 1.7 MW of electricity to sustain the food supplement production and 60 bar(g), 450°C steam required for the manufacturing process. With the simple yet highly efficient radial design of the turbine, the OP16-3B system delivers high temperature exhaust gasses at 575 ⁰C with a flow rate of 8.4 kg/s. These exhaust gasses will be recovered by producing 5 tons of high-pressure steam in a waste heat recovery boiler. By using a duct burner, the total amount of steam can be increased to 20 tons per hour. At the average annual temperature of 10°C, the electrical output at site is 1700kW of which most is used internally in the factory. As the OP16-3B is running parallel to the grid, any surplus electrical power will be exported to the national grid.


The BASF project is governed by the German regulation, “Bundesimmisionsschutzgesetz (TA-Luft), and these requirements must be fulfilled when operating both the duct burner and the turbine simultaneously. The all radial OP16-3B gas turbine rated at 1.85 MW (ISO conditions) designed by OPRA Turbines B.V, comes equipped with a Dry Low Emission system, providing full-load turbine emissions far below TA-Luft requirements of NOx and CO.

OPRA Turbines will also carry out the maintenance on the gas turbine generating set with OPRA’s in-house maintenance department. Due to the OP16-3B Gas Turbine robust and simple design the scheduled maintenance comprises only one minor yearly inspection and a major overhaul after 44.000 fired hours.




In August 2013 OPRA has opened an office in Singapore to further strengthen sales activities in Singapore and increase local support to existing and future customers in South East Asia.


‘The opening of OPRA Turbines’ Singapore office is an important step towards realizing the market potential in South East Asia for power generation in the 1-10 MW range and increase local support for the growing fleet of OP16 gensets in the region. The need for gas turbines in the 2MW range for combined heat and power (CHP) for process industries has been high. There has also been much interest from offshore oil and gas projects in the region.’ Fredrik Mowill (CEO, OPRA Turbines)



In the second quarter of 2012, OPRA Turbines opened an office in Moscow, Russia to further strengthen sales activities in Russia and to increase local service support to existing and future Russian customers.

‘The opening of OPRA Turbines new Moscow office is an important step towards realizing the market potential in Russia for power generation in the 1-10 MW range and increase local service support for the growing fleet of OP16 gensets in the region. The need for gas turbines in the 2MW range to run on flare gas in remote oil fields has been high. Currently almost 50 OP16 gensets are in operation in Russia.’ Fredrik Mowill (CEO, OPRA Turbines). Furthermore, OPRA’s business is growing and 10 OP16 gensets have been sold so far during the first half of 2012.

The first OP16 gas turbines delivered in 2005 in Russia achieved over 50.000 operating hours towards the end of 2011 running on associated gasses at the Tedinskoe oil. The Tedinskoe oil field is operated by Lukoil Sever and the OP16s use wellhead gas to supply 1.8 MWe each. They are attached to hot-water boilers providing 3 MW each in thermal energy. “One of the unique aspects of this project for our company is that the turbines are running successfully on the sour gas, which has a sulphur content of between 2 and 3% — which is very high, as the maximum allowable levels are typically below 1%,” “We can achieve this because the turbines are a simple yet robust design without cooling holes — radial turbines will keep on running as they are much less sensitive to pitting and corrosion.” said OPRA Chief Executive Fredrik Mowill.


Similar results were achieved on further sites in Russia in 2012.


'The clean, high temperature exhaust of the OP16 is ideal for industrial CHP applications. The market for low emissions gas turbines in the 2MW range has proven to be significant.' Fredrik Mowill (CEO, OPRA Turbines). In 2012 OPRA Turbines sold numerous units for CHP projects and entered new markets in Germany, Romania, Estonia and Indonesia.


The turbine’s robust and environmentally friendly qualities including low emissions combustion, fuel flexibility, high-temperature exhaust heat suitable for direct drying or steam production is a good fit for the paper, food and drinks industry. Low maintenance and high availability in a compact package are added benefits for industrial customers.


The all radial OP16-3B gas turbine rated at 1.85 MW in ISO conditions, designed by OPRA Turbines B.V equipped with a Dry Low Emission system becomes a cost effective solution delivering 6 tons/hour of steam with emission levels lower than 25 ppm of NOx and CO.


German factories upgrade to OP16 gensets to comply with strict air regulation (TA Luft).


Governed by one of the strictest emission regulations in the world (TA-Luft), German companies were keen to meet the German air regulations requirements with some margin in addition to the need for continuous and reliable heat and power. A wheat starch producer and a cigarette manufacturer, both chose an OP16 genset to comply with the new standards, replacing an existing CHP system.


Crespel & Deiters is a wheat starch producer with a focus on the corrugated-board and paper industries. The OP16 genset will provide power for their factory in Ibbenbüren, Germany and the exhaust heat will be utilized for direct drying for the starch production.


OPRA Turbines also sold an OP16 genset to a well known multinational cigarette manufacturer, with brands sold in over 180 markets. Their plant, located in Germany, produces more than 10 million cigarettes packs every day, has an operation regime of 24 hour every day and would require approximately 1.7 MW of reliable electricity to sustain their production line. Furthermore the factory utilizes a large amount of high temperature steam in the manufacturing process of cigarettes. This steam is predominantly used to dry high quality tobacco. The OP16 genset will be connected to a parallel fired Waste Heat Recovery Steam Boiler (WHRSB) in order to generate up to 12 tons of high quality steam per hour. At the same time about 1.8 MWe will be generated at the average annual temperature of 9 ⁰C. The surplus electricity produced by the Gas Turbine Generating Set will be supplied to the grid.


OP16 gensets: Perfect fit for wooden board producers in combined heat and power mode


The Sorbes Group has facilities in Switzerland, Estonia and Ukraine and produces wood boards from wood chips and wood fibres.  Sorbes Estonia has a factory requiring approximately 2 MW of power and approximately 4 MW of heat for the production of their wooden board product range: ‘Repo by Sorbes’. The heat will be used to heat up the thermal oil through a heat exchanger and the rest of the heat will be used in the drying process.


Reliable power and steam for beverages factory in Indonesia


In 2012 OPRA Turbines also entered the Indonesian CHP market. PT. Amerta Indah is the manufacturer and distributor of a popular isotonic drink called ‘The Pocari Sweats’. PT. Amerta Indah is fully owned by the Japanese pharmaceutical giant Otsuka and was established in Sukabumi in 2004. The unpredictability of electrical supply and the location of the plant at 550m above sea level with a relative humidity of 90%, demanded a more reliable and robust solution and two OP16 gas turbines were chosen. PT. Amerta Indah requires 3MW of continuous electrical power and 12 ton/ hour of steam for their 24 hours production line.  The steam will be used to sterilize the water bottles and to prepare the isotonic drinks. The units were equipped with dual fuel for operation on both liquid and gaseous fuel for further reliability. A turnkey solution including gas compressor, waste heat recovery steam boiler (WHRSB) and a supervisory control and data acquisition system (SCADA), supplied by OPRA Turbines, was provided to ensure the operability of the entire system, manageable by local technicians.


The reliance on fossil fuels is motivating EU leaders to find ways to transition to renewable sources of energy, in order to meet the targets of 80% to 90% reduction of greenhouse gas emissions by 2050. The EU’s 27 governments are committed to achieving the goal of obtaining 20 percent of their energy from green sources by the end of this decade in order to reduce emissions that contribute to climate change. Accordingly, Romania decided to take the measured steps by deciding to add 5% of ethanol in Gasoline.


With ethanol and alcoholic drinks in their product range, S.C. Marex S.A. located in Romania, is a food and beverage manufacturer equipped to provide approximately 10 million litres of bio-ethanol by using corn as their main raw material. To sustain the production demands, an independent electrical source was required to provide the more reliable electrical supply. To provide a more efficient system, S.C. Marex S.A., saw this opportunity to set up a combined heat and power facility on site. The OP16 gas turbine will be connected to a co-fired Waste Heat Recovery Steam Boiler (WHRSB) to generate up to 12 tons of high quality steam per hour. The concept of this project received support from the European Bank of Rural Development and was awarded with the 2011 EU EBRD Sustainable Energy Award.
