MILAN, Italy, 12 April 2024: Frascold announced the unveiling of the brand-new CO2 natural refrigerant-based TK HD series, a new heavy-duty sustainability frontier. Making the announcement through a Press release, Frascold said in a scenario where environmental protection is increasingly an absolute priority, it stands for the development of innovative solutions striving for continuous improvement and meeting all the needs of the industry. Frascold further said that the new TK HD series results from the company’s major investments in research and development, and this solution offers high performance, variable and persistent workloads and long service life. Moreover, the company said that the new series’ superior energy efficiency, reliability and excellent performance make it the right choice for various applications, including refrigeration, air conditioning, and high-temperature heat pumps up to 100 degrees C.

Frascold said that it delves into exploring innovation in each component, striving towards achieving maximum strength to ensure that its compressors can operate under harsh environmental conditions, constant round-the-clock workloads, at high temperatures and high delta P, while fully safeguarding the environment. Frascold also said that it focuses on using cutting-edge and top-quality materials to build long-service life compressors that are resistant to corrosion, heat dissipation, and optimised lubrication. In this sense, Frascold said, by providing the new CO2-based TK HD series with anti-friction treatments and a new surface finish, it is able to reduce wear and extend the service life of compressors for superior performance constant over time. In addition, the company said that reliability, resistance and duration were also confirmed by the field test, which was ongoing externally for a year. The option of fitting an inverter confers greater flexibility to the compressors, hence making them ideal to meet all the needs of the HVAC&R industry, Frascold further said. 

Frascold said the optimisation of the internal components and the painstaking mechanical balancing have contributed to significantly reducing the noise level, with a sound pressure range at a distance of one metre comprised between 64.5 and 76 dB(A), equivalent to the volume of a conversation for smaller models, or to the road traffic for size Z1. 

Frascold said the range includes two motor versions, four sizes, and 34 models, with a range between three and 50 HP and volumetric displacements comprised between 1.9 and 37.9 m3/h at 50 Hz. The company further said the range was conceived to bear pressure up to 100 bars and offers the utmost flexibility and compatibility with existing systems, enabling retrofit solutions. 

Frascold said that CO2 offers countless benefits compared to conventional synthetic refrigerants: Low global warming potential refrigerant fluid, which is readily available and non-inflammable, to the benefit of higher operating limits compared to propane gas. Moreover, the use of CO2 contributes to enhancing plant efficiency, which is a significant opportunity to reduce environmental impact and promote responsible management of energy resources to foster a sustainable future, Frascold further said. 

The company also said that the TK HD series is ideal for intensive and continuous round-the-clock workloads, like those required in industrial and trade industries.
