-120℃冷阱parylene 　　-120℃冷阱，主要用于parylene（派瑞林）真空涂覆，在parylene（派瑞林）工艺中，真空涂覆腔与真空泵之间的真空腔体存在不少残余的parylene物质和水蒸汽，parylene（派瑞林）冷阱在该真空度下可利用-120℃的低温来冷凝捕集残余的parylene物质和水蒸汽，从而很好的保护了真空泵，同时也提高了系统真空度，为parylene（派瑞林）工艺提供了良好的环境。 应用行业 applicable industries 用于生化石油、化工材料、低温液浴，气体捕集、科研实验等领域 this product can be applied in such fields as biochemistry, petroleum, chemical?materials, cryogenic liquid bath, gas entrapment, scientific research and experiment. 特点 features 1. 采用的单机自动复叠制冷技术，用一台压缩机，经过制冷系统的自动复叠，充入混合环保制冷剂，30min内可达到-120℃ 的低温； 2. 耗电少、噪音低、操作简便、制冷稳定； 3. 一般冷阱的蒸发器部分可做成棒式的和锅式的，也可以根据客户的需求设计不同形状的（右图为棒式冷阱）。 1. the advanced single-unit auto-cascade?refrigeration technique is adopted; one compressor is used; through auto cascade of the refrigeration system, environment-friendly mixed refrigerants are filled; the low temperature of -120℃ can be reached within 30min; 2. low power consumption, low noise, simple and convenient operation, and stable refrigeration; 3. commonly, the evaporator of the cold trap is of rod or boiler shape; different shapes can also be designed according to customers’ requirements (the right picture is a rod-shaped cold trap).
