Greenhouse/CHP Thinking ahead about profitability.

Our energy for our clients. From the first day on.

MWM Greenhouse – for profits that continue to grow, too. The future belongs to cogeneration, or CHP. We are facing high energy prices and, as an entrepreneur involved in greenhouse cultivation, you will be experiencing this at first hand. More and more entrepreneurs are therefore acknowledging the many advantages of decentralised power generation and want to benefit from this to the full.

MWM has been a global leading light in the field of engine and system expertise for decentralised power generation for 140 years. And one of our specific areas of expertise is greenhouses.

With the conventional (centralised) method, a large proportion of the output is wasted due to heat loss. This is not the case with CHP. With CHP, heat and power are generated ‘on site’. Decentralised power generation, therefore, using gas as fuel. As the power is generated locally, little energy is lost.

How you benefit, at a glance

In order to get the most out of your investment in CHP, it is important to take a specialised, 100 % transparent and experienced partner on board. That’s where MWM comes in.

• Fuel-independent: e.g. natural gas and biogas • Energy savings in comparison with conventional systems • Guaranteed CO2 reduction • Not dependent on scale • Not dependent on third parties • Extra returns by selling electricity • Attractive payback period

Inventory and advice

Testing and starting up

The process usually begins with a request for an offer, which we follow up within just a few working days. This is followed by an initial meeting and an extensive technical inventory. On the basis of this inventory, we present a substantiated plan of approach for your CHP installation – naturally taking optimum account of your requirements, wishes and specific situation.

Once your CHP installation has been fully positioned and assembled, an exhaustive testing phase follows. If this is completed successfully, your CHP can finally be put into operation. Normally, it takes no longer than six months between the date of the order and the point at which your installation becomes operational.

Positioning and assembly When all licences are in order and the installation has been designed to everyone’s satisfaction, the delivery and assembly of your CHP installation is scheduled. Together with a team of carefully selected suppliers, we direct the whole process from our office in Rotterdam. In advance, we make it perfectly clear what our responsibilities are and what you need to take care of. This means clarity for all concerned.

After-sales and service Even after your CHP installation has been delivered and is operational, you can fall back on us. Often, a CHP installation supplied by MWM comes with an all-in service agreement for 63,999 hours, as standard. All minor and major servicing is included in this, as well as remote inspection of the service monitoring system and changing the blocks in the flue gas purifier. Our service engineers are located all over the country, so they’re never far away.

Attractive payback period

This means that with a CHP installation, you don’t just produce heat. It requires little extra fuel, relatively speaking, to generate heat and power simultaneously. At any rate, less than when generating heat and power in separate installations. With CHP, total efficiency when converting fuel (gas) into power and heat is usually over 90 %. Specific measures can even lead to total efficiency of almost 100 %.

As a greenhouse owner, you can use all of the heat generated yourself. If you combine CHP with a flue gas purifier, you yourself can also make good use of the CO2 released. The extra profit that can be made from a CHP installation is related to the simultaneous generation of electricity. You can sell back any electricity you do not need yourself to the power company. Depending on the spark spread (difference between the price you get for the electricity you sell and the price you paid for the gas to produce it) and possible subsidies towards your investment in a CHP installation, the payback period for your investment could be just a few years.

Efficient MWM Greenhouse systems exploit the energy generated by natural gas or special gases for heating and lighting of the greenhouse. The processed CO2 generated in the combustion process can also be used as fertiliser.

Exhaust gas system CHP installations from MWM are supplied with a complete exhaust gas system. Components of this include a flue gas cooler and condenser, silencer and chimney. A large part of the system is produced in durable stainless steel. If a flue gas purifier is applied, the minimum 10-metre-high chimney has a CO2 connection with an electrically operated CO2 valve with a 100 % seal.

Outer casing is tailor-made You can choose to have your CHP installation indoors or outdoors. In both cases, we provide your installation with an acoustic enclosure in a whole range of colours. Together, we decide the size of the desired soundproofing for the casing. With a view to the environment and outward appearance, the floor in the casing has a watertight epoxy coating as standard.

CO2 fertilisation

Turnkey, trouble-free. MWM turnkey systems from a single source.

Catalysts are used to purify the waste gas produced by the engines. A heat exchanger cools the gas and the extracted heat is then used to heat the greenhouse. A blower system is used to transport the purified and cooled CO2 into the greenhouse, where it acts as an “airborne fertiliser” and encourages a very substantial plant growth. Measuring equipment is in place to monitor the quality of the CO2 that is fed into the greenhouse.

MWM engines The pulsing heart of every CHP installation consists of an extremely solid MWM engine. The MWM engine is characterised by high performance, high efficiency (and thereby Product Range: Gas low gas consumption), high quality and maximum reliability. We offer a wide array of different services – TCG 2032 supplying the most efficient 16 cyl.solution for your specific needs.

We supply your CHP installation including low voltage and control panels. If we deliver a 10 kV generator, the medium voltage distributor and medium voltage cables from this generator to the distributor are not included in our scope of supply. The engine management system is controlled and monitored automatically. All relevant information on power, temperature and possible faults is presented clearly on a touch screen. The software automatically reports any faults to our troubleshooting service, which operates around the clock, so that we can take action immediately. In many cases, we can also resolve problems from a distance.
