异丁烷（R600a）是家用冰箱和冰柜中最常见的碳氢化合物（HC），而丙烷（R290）则常见于商用热泵、空调、制冷和冰柜应用中。
碳氢化合物除了具有环境效益外，还是一种用于加热/冷却和冷冻的低成本的选择。碳氢化合物替代品是碳氟化合物（目前缺乏绿色证书）的常用替代品，与许多现有系统中的机油和部件兼容。它们的采购成本更低，能效更高，运行成本更低。
25 年多来，思科普一直在开发和推广使用碳氢化合物（R290 和 R600a）的高效压缩机。1993 年，丹佛斯压缩机（思科普）推出了 R600a 压缩机，1999 年又推出了 R290 压缩机。
碳氢化合物 R600a 和 R290 的引入有助于保护环境，并利用最新一代的高效压缩机技术更新了商用制冷系统。
我们成功的 R290 压缩机系列不断更新，为低背压和中背压应用不断推出更高效的型号，专门为商品陈列柜、餐饮服务、食品零售、医疗冰箱和超低温冷冻箱而设计。
这些 NLE、SCE 和 KLF系列的压缩机专为商业用途量身定制，可用于替代使用 R404A 和 R134a 等全球升温潜能值 (GWP) 较高的制冷剂制造的产品。
新型 50/60 Hz 压缩机专为支持环境恶劣和具有挑战性的地区而设计，在这些地区，需要考虑电压波动和环境温度过高的问题，并且在低电压条件下启动而不失速的能力也非常重要。
At Secop, natural refrigerants primarily refer to the hydrocarbons isobutane (R600a) and propane (R290). These replace fluorinated refrigerants (e.g., HFCs) and are considered more environmentally friendly because they have no ozone-depleting potential and a significantly lower global warming impact.
Because they offer several advantages: they are compatible with many existing components and oils, they are more cost-effective to purchase, and they enable higher energy efficiency and therefore lower operating costs.
Secop (formerly Danfoss Compressors) introduced its first compressors for R600a in 1993 and for R290 in 1999. This gives the company more than 25 years of experience with these natural refrigerants.
Secop uses natural refrigerants primarily in commercial refrigeration and freezing applications (light commercial – LBP/MBP), in food service and retail equipment, as well as in medical cooling and ultra-low-temperature applications.
Key advantages include: high energy efficiency (e.g., savings of up to 40% compared to conventional systems), the ability to use lower refrigerant charges, improved environmental performance (no ozone depletion, very low GWP), and low-leakage system designs.
By using natural refrigerants with low global warming potential, by providing energy-efficient compressors, and by helping reduce the overall CO₂ footprint, Secop’s solutions make a direct contribution to sustainable refrigeration and climate protection.
