Efficiency in its purest state A new generation of Chillers and Heat Pumps: more efficient, ecological and sustainable

The new R-32 series by Hitecsa reflect our constant commitment to innovation and research, with the clear aim of contributing to minimizing the environmental impact, achieving significant improvements in efficiency and increasing comfort and well-being. As a result, the new range of Chillers and Heat Pumps Kr3, R-32 SERIES, represents a step forward in climate control with hydronic systems. Discover the major benefits of this range, “dynamic” and flexible, which uses water as a heat-carrying fluid and an ecological refrigerant to achieve the highest levels of efficiency

The “dynamic” flight of the albatross: energy efficiency and savings Soaring birds can remain in the air for a long time with the minimum effort, and the albatross is a clear example of it. Its secret lies both in its anatomy and its flight technique. Thanks to its long but narrow wings it can glide through the air during a long time, wasting very little energy, since it does not need to flap them because of a “shoulder blockage” by a special tendon which locks them when they are fully extended. Besides, this long-distance traveler is known for practicing a flight technique known as...

ENERGY EFFICIENCY 30% LESS QUANTITY OF REFRIGERANT R-32 is a HFC pure refrigerant gas, with a very low Global Warming Potential (GWP: 677), high efficiencies and a great power of refrigeration. The EU legislation has established that gases with a high GWP will gradually disappear. The European regulation EC 517/2014 states it is mandatory for all European countries to replace fluorinated gases (F gases) due to environmental reasons and pollution. They are being progressively replaced by R-32, with 0% impact on the ozone layer, higher energy efficiencies, 30% lower charge of refrigerant and...

New range Kr3, R-32 series: for a more efficient and sustainable comfort HIGHER ENERGY EFFICIENCY R-32 is a more energy-efficient refrigerant gas in respect to the traditional ones. R-32 allows to achieve a 13% heating capacity level and a 4% COP rate higher than R-410A. This means that with a lower charge, higher capacities and efficiencies can be obtained. R-32 has a 2.9% cooling capacity level and a 6.4% EER rate higher than R-410A at standard conditions. MAXIMUM ECONOMIC SAVINGS With R-32, less quantity of refrigerant is needed (30% less than R-410A). Besides, its reduced tax cost, due...

MAXIMUM ECONOMIC SAVINGS ENVIRONMENTALLY FRIENDLY R-32 is a more energy-efficient refrigerant gas in respect to the traditional ones. The lower GWP and its higher efficiency contribute reduce direct greenhouse effect, due to lower CO2 emissions from the electricity production system. R-32 allows to achieve a 13% heating capacity level and a 4% COP rate higher than R-410A. This means that with a lower charge, higher capacities and efficiencies can be obtained. The equipment and facilities carry less refrigerant fluid, so there are fewer emissions of this gas into the atmosphere. The lower...
