I'm looking for a high temperature heat pump that operates on DC inverter technology, ideally within the 25 kW to 30 kW capacity range. The heat pump should be suitable for industrial applications, offering high efficiency and reliable performance, particularly in demanding conditions. Please let me know about the models available that meet these specifications, along with their technical details and pricing. Additionally, I'm interested in understanding the energy efficiency ratings and any certifications the units might have. It would also be great to know about the warranty terms and after-sales support provided. If there are any recommended installation practices or compatible accessories, please include that info as well. Looking forward to your prompt response.
