Features功能

Air-Cooled Condenser

风冷冷凝器

Eliminates the requirement for cooling water.

替代冷却循环水,适用于建造循环水塔或冷水机受限制的低温范围小的步入式试验箱

Shelving

产品架

Free-standing, foldable, and wall-attached shelves are available.

独立式、折叠式、箱壁连接式货架。

Dry Air Purge

干风吹扫

This option enables reduced moisture operation at low temperatures, dew points at -40°C. The system consists of a flow meter, regulator and control solenoid for program operation. It utilizes compressed air as the supply source and is very helpful in minimizing moisture in the chamber.

此选项可用于露点在-40℃以上,可减少水分在低温下操作。该系统由一个流量计、调节器、控制器和空气导管组成。需要压缩空气作为供气源。

Multiple Door Sizes

多门设计

Choose from several sizes of hinged, sliding, and bi-parting hinged doors.

可选择单开门、双开门、滑动门和过度间。

Humidity Purification System

纯水机

Multi-stage filtering reverse osmosis water purifier for purifying the humidity inlet water.

多级过滤反渗透净水器用于纯化湿度进水。

Refrigeration Quiet Package

制冷安静包装

Reduces noise levels produced by the machinery, internal and external available.

减少由机械产生的噪音水平,分为内部和外部减音处理

Low Humidity

低湿系统

A standard humidity system is designed to enable temporary operation down to -10°C dew point. A low humidity option will enable extended operation down to 5 grains of moisture per pound of dry air minimum limitation and humidity range from 5% RH to 98% RH.

一个标准的步入式高低温湿热试验室可实现-10℃的露点温度,使用低湿系统能实现5%~98%的湿度测量范围。

The low humidity option incorporates a dry air purge for ultra low dew points. It also adds a bubbler humidity system which allows small amounts of moisture to be added to the air for low humidity control. This eliminates problems associated with adding hot steam to a cold environment which creates two problems: heat that needs to be taken out of the system and steam generator oscillation.

除湿机融合了超低露点的干风吹扫,潮湿空气通过转轮的处理区时,湿空气的水蒸气被转轮活性硅胶吸附,干燥空气被输送到试验箱。除湿循环过程会带来蒸汽发生器振荡的问题。

Spreader Plates

摊铺承重板

A stainless steel plate on the chamber interior floor to increase point loading capabilities and rolling loads. The plate distributes weight evenly across the floor to prevent denting and to support heavy loads.

不锈钢承重板,铺设在试验室底部,增加点荷载能力和轧压负荷,以防止底板凹陷和支持更重的产品。

Multi-point monitoring

多点监控

Removable temperature sensor

可移动温度传感器,时时监控产品表面温度。
