The off highway business is changing towards more fuel-efficient solutions at a rapid pace, placing demands on compact, well-integrated and designed cooling. We combine advanced simulations with creative engineering and quality production to deliver top-of-the-line performance with full attention to fuel consumption and the environment.
At lower engine power output and temperatures, only the charge air needs cooling. To save fuel and increase cooling efficiency, we’ve split the airflow so that the CAC can be independently cooled by two electric brushless fans.
Our side-by-side coolers integrate the AC condenser. Aside from saving space, this means air flow is kept cooler and the whole system becomes less sensitive to clogging and dirt.
By integrating a temperature and pressure bypass valve in the oil cooler, we achieve a compact, cost-efficient and fast-track solution that enables the oil to reach the correct temperature. Once the temperature is reached, the bypass automatically works as a pressure bypass valve. The integrated bypass reduces the need for extra components and dramatically reduces the risk of damaging the oil cooler.
Our calculation software gives us a wide array of air fins, fans, fan houses and fan guards to model optimal airflow and cooling efficiency based on different applications and environments.
We can also simulate a range of turbulators and fluids to model temperatures, flows, and internal pressure drops. Combined, fluid and pressure simulations help optimize the coolers from both a cost and efficiency perspective and lead to a solution that best matches the customer’s need.
In short, we offer a complete cooling solution including AC condenser for the whole machine, delivered with mounted expansion vessel, fan gaskets and attachments for easy slot-in installation. Optimized for efficiency, stability, and lower emissions to provide a long lifecycle of savings for your end customer.
The advent of large electric vehicles poses interesting challenges as well as opportunities. Heat isn’t an ample byproduct, “refueling“ becomes a time-consuming task and batteries need careful temperature management. Our thermal management systems are a complete solution that keeps everything running at the right temperature, as long as possible – day-to-day and year after year.
Our new cooler is designed especially for the lower working temperatures of electric vehicles, offering reductions in both weight and size. By minimizing the use of compressor and fans to save energy, it helps decrease battery usage and increases the vehicle’s operating range.
Our integrated high-voltage compressor supersedes the HVAC compressor and supplies cooling for both the HVAC and battery. It is directly driven from the main high-voltage battery for maximum efficiency.
High-voltage heaters deliver heat for both the battery and HVAC. The heaters (high-voltage driven to eliminate energy losses caused by conversion) are managed by the control system and used sparingly since heat generated from the driveline is used.
The control system in our Thermal Management Systems, in conjunction with our expertly programmed ECU, take ambient temperatures and driving cycles into account in order to carefully balance cooling and heating needs throughout the system – always with the aim of conserving the battery to increase the vehicle’s operating range.
Our TMS makes sure that every component is cooled to its individual optimal operating temperature. To save energy, excess heat is recycled and used for heating the cabin and battery.
To ensure peak performance and a long life cycle, the battery temperature is constantly monitored and kept at an optimal 25°C.
To keep the system efficient, simple and compact, the HVAC is supplied with heater and compressor
We deliver complete Thermal Management Systems characterized by high flexibility and a modular approach where an intelligent ECU works in tandem with coolers, heaters, pumps and compressor – all tailored for electrical vehicles with three goals in mind: smooth operation, energy saving and high efficiency.
Ymer Technology’s wind division that develops and manufactures cooling systems for on- and off- shore wind turbines has been acquired by the Power and Motion company, HydraSpecma. With the transaction HydraSpecma strengthen its position as leading supplier within the wind industry.
With the acquisition of Ymer Technology’s wind division, the international Power & Motion company HydraSpecma headquartered in Skjern, Denmark is becoming an even stronger supplier and development partner to the wind industry. The two companies have recently settled an agreement which will increase strength and capacity to accept even more projects within the wind power segment.
HydraSpecma, that is owned by the Danish industrial conglomerate Schouw & Co, has acquired Ymer Technology’s wind division that is headquartered in Silkeborg, Denmark. HydraSpecma sees a great potential in the wind industry the upcoming years and the two companies will complement each other in multiple areas. HydraSpecma is specialized in lubrication- and filtration systems and pitch-hydraulic, while Ymer Technology have cooling and conditioning of nacelles as their primary business area.
The goal, to achieve an even stronger position in the market has also played a significant role for Ymer Technology Jørgen Krogh, Vice President of Ymer Technology explains. In few years, Ymer Technology has established a robust customer portfolio due to the company’s expertise, especially within cooling systems for wind turbines.
– Through a close cooperation with our customers we have taken significant steps within development. We have gone from being a component supplier to co-developer of systems to some of the largest OEM customers. Now the time has come to take the next large step. The winds of change are blowing within the wind industry and to stand even stronger in that process I see Ymer Technology and HydraSpecma as the perfect match, says Jørgen Krogh.
HydraSpecma have been collaborating with the leading wind turbine manufactures in more than 40 years and are experiencing and increasing demand with the wind power segment. The acquisition of Ymer Technology’s wind division is a prolongation of HydraSpecma’s strategic ambition to strengthen their position with the growing industry.
– HydraSpecma and Ymer Technology is similar in many areas. Both companies excel in service excellence and they both have a flexible production on a global scale, which makes us a strong business partner. Together, we are ready to secure our customers the best complete solutions all the way from prototype development to serial production. We are convinced that this acquisition will make us stronger in this area in the future – Morten Kjær, CEO of HydraSpecma
During the discussions on HydraSpecma’s acquisition of Ymer Technology’s wind division, both Morten Kjær and Jørgen Krogh have been confirmed in the fact that the companies’ values are very close to each other. That has strengthened the belief that the acquisition and increased focus on the wind power industry will become a success.
The acquisition must also be seen in light of the increasing need in the market for consolidation.
– There is no doubt that size matter as a supplier to the wind industry. Our purchase volume and production capacity will increase, and we will stand stronger as we gain strength and capacity to take more projects from all customers and deliver complete systems. Morten Kjær emphasizes and adds that the acquisition will increase HydraSpecma’s revenue with approximately 575m Danish kroner.
HydraSpecma will be the continuing company and will continue to be headquartered in Denmark. HydraSpecma Group and Ymer Technology’s wind division respectively employs 1.300 and 180 persons and have production facilities in Asia, Europe as well as in North- and South America.
Ymer Technology was founded in Sweden in 2005 under the name Ymer Technology AB. Ymer Technology has specialized in cooling systems and thermal management systems. The company is headquartered in Stockholm and has production facilities in Sweden, China, India and USA. In 2021 Ymer Technology had a revenue of 1bn Swedish kroner and the company has 277 employees.
HydraSpecma was founded in 1974 and today it is Denmark’s largest supplier of Power & Motion systems as well as solutions for the wind power industry.
