The LMNT Revnu CASWR250B-T is a high-performance and energy-efficient air-to-water monoblock heat pump, specifically designed for large-scale applications in commercial buildings, industrial settings, apartment complexes and agricultural installations. This unit is built as a single robust outdoor module in which all essential refrigeration and hydraulic components are integrated. This simplifies installation and makes it an ideal solution for all-electric or hybrid heating systems.
The Revnu heat pump operates on natural refrigerant R290 (propane), which has a Global Warming Potential (GWP) of just 3. This makes it not only environmentally friendly, but also future-proof. Thanks to the high energy efficiency of propane, the system keeps operational costs low and provides long-term financial savings.
By extracting renewable energy from the ambient air and converting it into usable heat, the CASWR250B-T offers a sustainable and efficient solution for space heating, cooling and domestic hot water. The unit delivers excellent performance even in outdoor temperatures as low as -25 °C, and can supply water temperatures of up to 73 °C. This makes it suitable for both low-temperature systems such as underfloor heating and high-temperature radiators in renovation projects.
With high COP values, the unit produces more heat using less electricity, resulting in significant energy savings. Despite its high capacity, the system operates quietly, making it suitable for noise-sensitive environments.
With a maximum heating capacity of 75 kW, modulation range from 20.45 to 75.00 kW, and a domestic hot water capacity of up to 100 kW, the Revnu CASWR250B-T meets even the highest heating demands. It is equipped with two fan motors, a durable galvanised steel housing, and is fully prepared for integration into professional HVAC systems.
In the Netherlands, this model qualifies for the ISDE subsidy scheme. The available subsidy is €8,775 in 2024 and €11,125 in 2025 under registration code KA29023.
This heat pump can easily be combined with buffer tanks, boilers, and multi-zone systems. It is widely used in schools, apartment blocks, care centres, hotels, stables, production halls, and sustainable building projects.
