This technology make heat pump to keep normal heating without electric heater assistant in ultra cold ambient temp.

A+++ Energy label

Kolant's R32 refrigerant heat pump has achieved the prestigious A+++ energy class, a testament to its exceptional efficiency under the rigorous European standards EU813 and EN14825. This top-tier rating underscores the product's ability to deliver superior performance while minimizing energy consumption, aligning perfectly with Europe's stringent environmental and energy efficiency goals.
R32 refrigerant, known for its lower global warming potential compared to many traditional alternatives, is a key component in Kolant's commitment to sustainability. When paired with the heat pump's advanced engineering, it creates a system that excels in converting energy into usable heat, even in varying climatic conditions. The compliance with EU813, which sets requirements for the energy performance of space heating and cooling equipment, and EN14825, specifying testing methods for air-source heat pumps, ensures that every unit meets consistent, high-quality standards.
For European consumers and businesses, the A+++ rating translates to tangible benefits. It means significantly reduced energy bills over the product's lifespan, as the heat pump operates with maximum efficiency. Additionally, it contributes to lowering carbon footprints, supporting both individual and collective efforts to combat climate change.
Kolant's achievement in securing this elite energy class reinforces its position as a leader in sustainable heating solutions. By combining innovative refrigerant technology with adherence to strict European standards, the R32 heat pump not only meets but exceeds expectations, offering a reliable, efficient, and eco-friendly choice for modern heating needs.

Kolant EVl heating technology advantage

There is no doubt that air source heat pumps can make great economic and environmental benefits if they are properly used. However, as a matter of fact, most air source heat pumps work with very poor efficiency or even can not work when the environment temperature is lower than -10℃. It also extend the compressor working ambient temp to -35C. The EVl (enhanced vapor injection) heating technology is an innovation in the compressor and the refrigerant circulation. By this technology the permitted operating range of a heat pump is extended to a much lower air temperature region, and the heating performance under low environment temperature is greatly improved.

No electricity leaking, no refrigerant leaking

Heating, cooling and DHW in one solution for super low ambient temp.

Kolant heat pumps are engineered with a suite of unique design and production details that work in harmony to address three critical priorities:

preventing leakage, minimizing noise, and maximizing performance. Each feature is meticulously crafted to set the product apart in the competitive heat pump market, delivering exceptional value to users.
First and foremost, the full insulation design is a testament to Kolant's commitment to efficiency. Unlike conventional heat pumps from other factories, which often suffer from energy loss due to inadequate insulation, Kolant's system employs a comprehensive insulation solution that covers all key components. This not only reduces heat dissipation during operation but also ensures that the system maintains optimal working temperatures even in extreme environments. The result is a remarkable 2% increase in COP (Coefficient of Performance) compared to industry counterparts. This seemingly modest percentage translates to significant long-term energy savings, making Kolant heat pumps a more cost-effective choice for both residential and commercial applications.
Another standout feature is the integration of two electronic expansion valves, a design choice that revolutionizes EVI (Enhanced Vapor Injection) control. Traditional heat pumps rely on thermal expansion valves, which are prone to imprecise regulation due to their dependence on temperature changes. In contrast, Kolant's dual electronic expansion valves use advanced sensors and microprocessors to adjust refrigerant flow with pinpoint accuracy. This precise control over the EVI process ensures that the heat pump operates at peak efficiency across a wide range of operating conditions, from mild to extreme temperatures. The impact is substantial: a 15% increase in COP compared to systems using thermal expansion valves. This boost in efficiency not only reduces energy consumption but also enhances the heat pump's ability to deliver consistent performance when it matters most.
Kolant's smart pre-design anti-vibration kits are a key factor in preventing leakage and ensuring long-term reliability. These kits are far more sophisticated than the standard anti-vibration solutions commonly displayed in the market. They are engineered to absorb and dampen vibrations at multiple points within the heat pump, from the compressor to the refrigerant lines. By minimizing vibration, the kits reduce stress on connections and seals, which are often the primary sources of leakage in heat pumps. This proactive approach to vibration control not only prevents costly and inconvenient leaks but also contributes to the heat pump's ability to operate without the need for frequent aftersales service. Users can enjoy peace of mind knowing that their Kolant heat pump is designed to be virtually maintenance-free, with a focus on durability and longevity.
Last but not least, the combination of a flying bird wing fan and an EC (Electronically Commutated) fan motor is a masterstroke in noise reduction. The flying bird wing fan is inspired by nature, with a blade design that minimizes air turbulence and reduces noise generation. This aerodynamic design allows the fan to move air efficiently while producing less sound. Complementing this, the EC fan motor operates with greater precision and lower energy consumption than traditional motors. It adjusts its speed dynamically based on the heat pump's cooling needs, further reducing noise levels during operation. Together, these components create a significantly quieter working environment, making Kolant heat pumps ideal for use in residential areas, offices, and other spaces where noise pollution is a concern.
In summary, Kolant heat pumps stand out in the market due to their thoughtful and innovative design. From the efficiency-boosting full insulation and dual electronic expansion valves to the leakage-preventing smart anti-vibration kits and noise-reducing fan system, every detail is engineered to deliver superior performance, reliability, and user comfort. These features not only set Kolant apart from its competitors but also make its heat pumps a smart choice for anyone seeking a high-quality, efficient, and low-maintenance heating solution.
