High Efficiency and Energy Saving

One of the most prominent features of Kolant modular heat pumps is their high efficiency and energy-saving performance. The heat pumps are equipped with compressors from internationally renowned brands, which are known for their superior quality and efficient operation. To further enhance the heating capacity, they are designed with a plate heat exchanger-type economizer and an enlarged evaporator area. This combination of advanced components and thoughtful design results in a 20% increase in heating capacity compared to traditional models. What's more impressive is that even in extremely low temperatures as low as -35℃, the heat pumps can still maintain a strong heating capability, ensuring a warm indoor environment for residents in cold regions. In addition to the hardware advantages, the system also achieves efficient energy saving through program optimization and intelligent control. The intelligent control system can monitor the operating status of the heat pump in real-time and adjust the operating parameters according to the actual heating demand, ensuring the system operates continuously and stably while minimizing energy consumption.

Noise Reduction Design

In residential areas, noise pollution is a major concern that affects residents' quality of life. Kolant modular heat pumps address this issue with an excellent noise reduction design. The compressor, which is a major source of noise in heat pumps, is wrapped with white fiber sound insulation cotton in two layers. This double-layer wrapping effectively absorbs the noise generated by the compressor during operation. Moreover, multiple shock absorption and noise reduction measures are applied to the chassis and middle partition of the heat pump. These measures work together to reduce the vibration and noise transmission of the entire unit. As a result, the overall noise level of the Kolant modular heat pump is 10% lower than that of the previous generation product, creating a quieter operating environment for residents. This low-noise operation ensures that the heat pump does not disturb residents' daily life, whether it is during the day or at night.

Smart WIFI control

KOLANT heat pumps’ Wifi control function is a game-changer for smart living. Via the dedicated app, users can adjust temperatures, switch modes, or check operating status anytime, anywhere—whether at work, on vacation, or lounging at home. It seamlessly integrates with smart home ecosystems, syncing with thermostats, timers. Imagine preheating your home before arrival or setting a schedule to match your daily routine, all with a tap. This not only boosts convenience but also optimizes energy use, cutting costs while keeping comfort consistent. Wifi control turns heating into an effortless, intelligent part of modern life.

Modbus Protocol built inside

Beside Kolant heat pump wired controller and central controller, KOLANT commercial heat pumps built inside modbus protocol to be communicate with other central building system control, this means that your heat pumps can be controlled by a building automatic control system if it is necessary. You can control and monitor your heat pump working status through computer or any other modbus controller.

Stability and Reliability

Stability and reliability are crucial factors for heating equipment, especially in harsh environments. Kolant has 35 years of experience in heat pump technology research and development, which has laid a solid foundation for the stability and reliability of its products. The products have passed the EU813, EN14825, EN14511 standard test, which is a strict international standard for air-source heat pumps. Passing this test indicates that Kolant modular heat pumps meet high-quality and performance requirements. In addition, these heat pumps have been put into practical application in extremely cold regions such as Northeast China, where the climate is harsh with very low temperatures in winter. The successful operation in these regions fully verifies the stability and durability of Kolant modular heat pumps. Whether facing long-term continuous operation or extreme weather conditions, the heat pumps can maintain stable performance, providing residents with a reliable heating guarantee.

Kolant Modular commercial heat pump installation project reference

Kolant modular heat pumps have a wide range of applicable scenarios, making them suitable for various heating needs. They are not only applicable to residential districts but also to commercial buildings such as office buildings, shopping malls, and hotels. One of the advantages of these heat pumps is that they support direct heating with stable outlet water temperature. This avoids the problem of outlet water temperature fluctuation that is common in traditional circulating heat pumps, ensuring a stable and comfortable heating effect. In addition, through electronic expansion valve control technology, the heat pumps can adapt to temperature changes from -35℃ to 43℃. This wide temperature adaptation range allows them to operate efficiently in different climate regions, whether in cold winters or hot summers. The electronic expansion valve can accurately control the flow of refrigerant, ensuring efficient heat exchange and maintaining the optimal operating state of the heat pump under various temperature conditions. In conclusion, Kolant modular heat pumps, with their characteristics of high efficiency and energy saving, noise reduction design, intelligent control, stability and reliability, and wide applicability, have become an ideal choice for residential district heating. They not only provide a comfortable and warm living environment for residents but also contribute to energy conservation and environmental protection, bringing more convenience and benefits to users.
