![]() ![]() Because R32 efficiently conveys heat it requires less refrigerant volume per kW. With a GWP* (Global Warming Potential) of 675, R32 is less than half of R410A, which has a GWP of 2090. R32 has less environmental impact than R410A which is currently the international refrigeration standard. ![]() Chofu’s second generation, air-to-water heat pumps with R32 was the first of its kind to be rolled out across New Zealand.
