Walk-in Rooms

Walk in Chamber

Walk in chamber comes in a variety of sizes, from a small box that fits on the bench top to a room-sized chamber for large objects or for testing large batches of product simultaneously. Temperature ranges from -60° C to 150° C and relative humidity ranges between 20% and 90% are available. A temperature humidity walk in chamber can also be used when constant climate conditions (temperature and/or humidity) are needed for product testing.

Walk in test chamber simulates the effects that a range of temperature and humidity conditions have on a product or material, for example telecommunications equipment or photovoltaic solar panels that are exposed to outdoor temperature and humidity conditions.

Question: The testing item has, 3000kg, steel part that is attached to the floor. The ideal temperature range is -50°C to 160°C and will also need a humidifier to reduce icing. The size is 8’W x 10’L x 7’H . Can this be done ?
Answer 1: I noticed the temperature range request is -50°C to 160°C, We can make it !
Answer 2: But I am not sure why you request a -50°C to 160°C, Because when the wall going to temperature upto to 100°C, It will be aging rapidly. And it can not be tested for many hours. The wall not made by steel, They are the insulation plate, It can not afford the highly temperature always !
Answer 3: Meanwhile, We have the temperature oven, the MAX temperature is +250C, Maybe you can use our temperature oven for highly temperature test. This may more reasonalbe solution for your reference.
