Heat transfer solutions that match your requirements
Next-generation heat exchangers from Danfoss are designed with a single purpose in mind - to create optimal heat transfer. Developing optimized solutions is a core value of our design philosophy, and we have used our deep process knowledge and input from customers to create a second-to-none heat exchanger plate portfolio. Our many plate varieties ensure that we can better configure our heat exchangers to match the exact requirements of your application and deliver a powerful solution that provides reliable, unmatched heat transfer while lowering the energy consumption of your connected systems. We are always in direct contact with you to ensure that each heat exchanger is designed around your application and your media.
Closed-loop production
We are specialized in the development and manufacture of heat exchangers. We do all our own tooling and have our own hydraulic presses in-house. This closed-loop production makes it easier to control and monitor the quality.
Efficiency is key
The secret ingredient to an efficient installation is how closely your heat exchanger matches the thermal requirements of the duty. If the heat exchanger is oversized, you will have paid too much for it. If it is undersized, you will either need additional heat exchangers, or you will have to add extra (expensive, non-regenerative) energy elsewhere in the process to reach the desired media temperatures.
Standard plate heat exchangers
Our standard plate heat exchangers are the ideal choice for a wide range of applications across numerous market segments. We have one of the largest plate portfolios in the world, and we configure each heat exchanger to meet your requirements.
