Solutions for residential and commercial hydronic heat pumps
Residential heating: greener heating for houses, from source to distribution
Our comprehensive R290 offering accounts for more than half of the bill of materials (BOM) value for a typical A/W residential heat pump—from the rotary and drive compressor package to the gas detector and the universal controller—streamlining design processes, reducing sourcing complexity, and accelerating time to market. When integrated with our hydronic portfolio, we provide the most efficient heating architecture, enabling homeowners to manage energy usage and costs effectively. Enhancing the energy efficiency of single-family homes is a crucial step toward decarbonization.
Commercial heating: greener heating for buildings, from source to distribution
Ensure year-round efficiency with our comprehensive R290 offering, encompassing compressors, heat exchangers, electronic controllers, valves, controls, gas detectors, and sensors. Attain lower supply temperatures and enhanced efficiency through our variable speed compressor paired with a brand-new HVAC drive, capable of delivering water temperatures up to 80 °C. When integrated with our hydronic portfolio, eliminate pressure and flow deviations to achieve effective performance in both full- and part-load conditions. Enable lower supply and return temperatures for a sustainable heating solution.
Commercial heating: climate-friendly heating for buildings, from source to distribution
The multi-refrigerant component portfolio, encompassing compressors, heat exchangers, valves, controls, gas detectors, and sensors for R454B/R32, offers ultimate flexibility for system design and competitive applied costs. The PSH scroll compressor, featuring innovative liquid injection technology dedicated to A/A and A/W heat pumps in cooler climates, enables heating water up to 150°F at ambient temperatures as low as -5°F. When paired with our hydronic portfolio, it enhances overall building performance with a sustainable heating architecture.
Solutions for commercial and industrial heat pumps
Up to 100°C water temperature, with low-GWP HFC, HFO, and natural refrigerants
Above 100°C water temperature
The SuPrHeat Project
The project "SuPrHeat—Sustainable process heating with high-temperature heat pumps using natural refrigerants is an interdisciplinary and cross-cutting research, development, and demonstration project with 16 partners from Denmark, Germany, UK and Sweden.
Achievement: a 500 kW HTHP operational at DTI, built on the following specifications
- A pentane/butane cascade system, capable of achieving a maximum condensing temperature of 150°C
- The system integrates Danfoss industrial refrigeration components and BOCK® compressors featuring cylinder cooling and special oil
- Project partners plate heat exchangers and controllers
- The project is containerized, eliminating ATEX zone requirements
