CTC is one of Sweden's leading heating technology manufacturers, with more than 100 years of experience in developing environmentally friendly and energy-efficient systems. The company is located in Ljungby, Sweden, and is part of the NIBE Group. CTC offers modern heating equipment – both air-to-water and geothermal heat pumps, indoor modules and smart control systems.

CTC began producing air-to-water heat pumps as early as 1981, and today the company's production area exceeds 20,000 m². All heat pumps are developed and manufactured in Sweden, ensuring compliance with the highest quality standards. All CTC heat pumps are supplied with a 5-year warranty, confirming their reliability and durability.

The CTC EcoAir 600M and 700M series are the latest-generation inverter-controlled air-to-water heat pumps, offering high performance, low noise levels and A+++ energy efficiency. The outdoor units automatically adapt to the home's heating and hot water needs throughout the year, providing comfort in all weather conditions. They feature an attractive, elegantly designed casing that fits perfectly into any environment.

The EcoAir 600M series is a proven and reliable solution that has demonstrated its performance in thousands of households over the years. EcoAir 700M, in turn, is CTC's latest technological achievement – efficient, quiet and equipped with modern control options, including a cooling function and smartphone control.
