                                  Suscessful drilling
                                  There are always uncertainties that you can not control in a drilling project. Experience is obviously important, but also that there are procedures and check points. We want our clients to feel secure in the implementation and therefore is the geological feasibility study important. It gives us the answers and what we can expect when drilling. Sometimes a eploration drilling is required to provide further responses to the dimensioning of the well. The well drilling is always done after a given routine and with as little environmental impact as possible. Completion and installtion of the well equipment is always under Malmberg method and according to Normbrunn 07 (Sweden).

                                • Geothermal energy from groundwater or bedrock is often used for the heating and cooling of buildings. We have extensive experience of drilling and designing groundwater and collector wells and, in fact, we are pioneers in Sweden in this field. For example, we drilled the groundwater wells for the world's largest geothermal energy storage at Arlanda Airport outside Stockholm​.

                                  What can you expect from us?
                                  When an energy drilling is planned, we take care of the feasibility study, we conduct geological tests, dimensions with respect to the number of boreholes and the depth required. We drill and take it all the way to the deployment of a fully optimized system. Naturally, we offer service and maintenance too.

                                  Dimensioning of energy well
                                  The energy wells must be dimensioned properly. We carry the thermal response test to determine soil conditions such as temperature, conductivity and resistance. The results show the number of wells required, depth and location of the wells.

                                  Energy Drilling
                                  The life-span of an energy well is at least 100 years. During these years, heat pumps and other equipment are replaced 4-5 times. We are professional driller with drilling machines specialized for energy drilling. With our experience and modern drilling equipment we always ensures that the bore hole energy exchange is optimized and meets the requirements and lasts for at least 100 years.
                                • Infrastructure

                                • Groundwater lowering and anti-skid roads
                                  At the construction of roads, viaducts and bridges many times need to lower the groundwater and then keep it at the right level. We manage the documentation needed with regard to geology and capabilities in order to then carry out the drilling and make a complete well installation with control equipment. With a service agreement, we can also take care of maintenance of the well system and provide with the background values needed for water rights.

                                  Geothermal energy for anti-skid roads
                                  Accidents due to icy roads is a major problem. Most often, it´s road section with level increases or decreases where the accidents happen. Energy wells can solve this problem by seasonal storage the summer heat in the bedrock and then to be used during the winter. Benefits apart from reduced risk of accidents are low operating costs and an environmental impact. The system can be applied for skid- and ice control on particular road surfaces, train gears, platforms and tunnels.
                              • Enviroment and quality

                                    • Malmberg Drilling means high quality, better environment and safe working environment

                                    • To perform a water well or energy well means large machines working and moving around. It requires planning of the works and experienced staff that know the routines. We stand for a safe work carried out by modern machinery, well trained and experienced staff who always gives his utmost and act professionally. We are ISO 9001 certified to quality, environment ISO 14001 and health and safety OHSAS 18001.
                                • Rebuilds and improvements

                                • Irrespective of age and function of drinking water wells, they may need a rebuild or upgrade. It may be increased requirements due to the working environment, so that the well can be managed on a service-friendly manner. Or for environmental reasons, to secure the drinking water so that the well installation is not open to undue or to prevent infiltration of contaminants.

                                  Do you have an old well with piping below ground level?
                                  We perform renovation of the well pipes by relining for both rock and filter wells. Old wells have many times piping below ground level and then we can extend the well pipes to above ground as well as upgrade and modernize the entire well installation. New well superstructure provides a secure perimeter and makes servicing easier.

                                  Take the opportunity to upgrade your wells with electricity and automation from Malmberg.
                                  We offer a complete solution for your well with easily foreseeable panel that displays important control parameters and alarm functions. Of course, it can be controlled remotely if you want to, and connects to an overall system.

                                    • Reconditioning of wells

                                    • Increase the well capacity with Jet Master®
                                      We master all the conventional methods for reconditioning of wells, from the simplest form of the blowing with compressed air, packer and mammoth pumping to jet pulsation and chemical cleansing. Each service unit is equipped with a compressor in addition to supply compressed air but also provide a pump with power. Moreover, we have a comprehensive range of pumps for rental and we also offer maintenance of pumping and pipe equipment for operational optimization.
                                      JET Master® clean out pumping
                                      We are the only drilling company in Sweden that uses the unique JET Master® method for cleaning of the filter wells. In most cases it results in a capacity increase of more than 100 percent. What is unique is the vibration induced by flushing through 4 nozzles. They rotate up to 10 000 rpm and in the combination of high pressure water gives it the unique pulsating effect. The vibrations get sand and gravel grains to vibrate and rotate and the detached coatings and oxides of the gravel formation is pumped up continuously. All waste is then pumped out of the well.

                                      What types of wells can be reconditioned with Jet Master ®?
                                      JET Master® can be used in all filter wells of any material (steel, plastic, wood, concrete, etc.) with a well diameter of 100-1000 mm.

                                    • Our well superstructure Prisma has a simple and modern, perfect for the somewhat smaller well installation. Walls and hatch are sandwich panels with a layer of aluzink on the in- and outside. The insulating core is 40 mm extruded polystyrene. Prisma is standing on a base of aluzink, which is placed on a gravel bed or a concrete base.

                                      Protect your other water installations
                                      Prisma can also be used to protect water reservoirs. The superstructure is then placed above the descent door. It is also suitable for protecting valve installations above ground.

                                      Service-friendly and easy handling of your well installation

                                      The front of Prisma is easily opened by two spring dampers. Here is plenty of room by inspection and service- and maintenance. For larger service work the entire superstructure can be folded backwards and then exposing the installation. The pump- and electrical installation are completely protected from frost and external polution from th surface. The electrical equipment is mounted on a wall panel made of aluminum, 800 x 1000 mm, and is fixed on the base so it remains on its place when the superstructure is folded or off lifted.

                                        1. Energy well dimensioning
                                        It´s essential that the energy wells are dimensioned in a proper way. We perform the thermic response test to find out the ground conditions such as temperature, conductivity and resistance. The result gives the the number of wells , depth and placement of the wells.

                                        2. Energy drilling
                                        A energy well life span is at least 100 years and during these years the heat pumps and other euipment will be replace 4-5 times. We are professional drillers with drilling machines specialized in energy drilling. We use Comacchio drill rigs with Atlas Copco compressors. Measurements are contioniusly made during drilling regarding straightness in order to achive the most optimized drill hole for a energy exchange.

                                        3. Heat pump central design
                                        We have the technical expertise and resources to design a complete geothermal plant for a property. along. A pre-study of the propery´s heat- and cold demand and technical status is performed by us. The analysis gives us the factors to design an optimal plant with no energy losses. We design a compact and easy maintenance plant including heat pumps, pipeworks, electrical and automation.

                                        4. Manufacturing/installation
                                        Depending of the site and property the heat pump central can be either on site installed or pre fabricated. We have our own manufacturing site with highly experienced and skilled welders and metal workers.

                                        • Geothermal energy is a fantastic innovation. It´s completely sustainable and works for ever. When the sun shines the ground is heated up and this heat we utilize it in a smart energy system. A system that includes energy drilling for wells in borehole or aquifer storage and the design of the technology central. You can count on a fast pay-back for the investment. For every part of electrical energy you buy to run a geothermal energy plant you get at least four parts of free heat.
                                            • Geothermal heat

                                            • How geothermal energy is recovered
                                              Geothermal energy involves a building's heat retrieved from rock, groundwater or soil. The energy is then recovered using a cooled liquid circulating in a tubing system. As the fluid passes the heat pump it heats up the refrigerant inside the heat pump. Its then compressed and becomes a hot gas and is passed to a condenser where it exchanges its heat to the building's heating- and hot water system.
                                            • Geothermal heating/cooling

                                            • Stored heat and cold for a perfect indoor climate
                                              Generally, there are two different ways to utilize geothermal energy for heating and cooling. A bore hole storage means that a number of energy wells are drilled in a defined area forming energy volume. A aquifer system is appropriate in water-rich areas and is often used for large buildings such as hospitals, airports and other large facilities. The geothermal energy principal is simple. During winter, heat is extracted from the groundwater and the bedrock is cooled down a few degrees. As summer begins, the stored cold accumulated as "free cooling" and the bedrock or the ground water is heated gradually and becomes the source of heat next winter.

                                                • enerGeo™ provides efficient geothermal heating installation
                                                  Geothermal energy means that the operating cost efficiency for heating buildings considerably improves and at the same time it is a renewable energy. Geothermal heating installations in small and large properties are often quite inefficient. With our prefabricated geothermal energy central, Malmberg enerGeo™, the geothermal installations become more efficient.

                                                  Installed by docking

                                                  Malmberg enerGeo™ is a completely pre-built geothermal central and is easily docked to the energy wells, as well as the property's heating and cooling systems. The approach has several advantages compared with the site-built centrals. Energy Drilling and landscaping with connections are made on-site and in parallel the energy central is built in our workshop. The central is then delivered as a complete unit including the electrical, control and plumbing installations. It is the docking that makes enerGeo™ so smart, its completed in the workshop and just docked in. A site-built geothermal central often needs to involve multiple subcontractors and working in the customer's building for a long time. Thanks to a prefabricated solution, you have full control over production and ensures that costs are kept down, resulting in a lower price for the customer. It only requires a power supply and the entire facility is directly prepared for remote support if needed.

                                                  Operating cost-effective and environmentally friendly

                                                  Geothermal heating is operating cost efficient, environmentally friendly and a sustainable heating technology compared with other alternatives as district heating, pellet, gas or electric boiler. 1 part electricity for the operation of geothermal heating results in heat production worth 4 parts. 1 part electricity for the operation of free cooling results in produced cooling worth 40 parts. Besides, the geothermal energy is also CO2 neutral and a renewable energy source. If you, as a property owner then only uses green electricity, such as wind, solar or hydropower your facilities will be completely environmentally friendly.
