Introduction of walk-in temperature humidity test chamberThe walk-in constant temperature humidity test chamber is a large temperature and humidity te
Free QuoteThe walk-in constant temperature humidity test chamber is a large temperature and humidity test chamber. Its temperature and humidity range is almost the same as the small temperature humidity chamber. Due to the large internal volume, the power of the walk-in test room is higher than that of the small test box under the same temperature and humidity conditions.
The functions of the small constant temperature and humidity test chamber are the same with the walk-in type. Except that it cannot be moved at will and does not include the castor wheel, other configurations are similar.
The walk-in test chamber is used to test the response of products and materials to high and low-temperature humidity, or constant temperature and humidity environmental changes, and the parameters and corresponding properties are obtained.
The smallest walk-in chamber has 6-8 cubic meters and can be designed according to the customer's room layout.
All parts used in Noki's walk-in temperature humidity test chambers are brand new, and we never use second-hand or repaired parts.
The main functional components are all international brands, the technical principle is advanced and reliable, and the noise and energy saving are optimally controlled.
All wires in the control cabinet have serial numbers and numbers printed by special equipment, and the lines are clean and clear at a glance.
Due to the large environmental impact, Noki currently recommends customers make the walk-in outer dimension into the inner dimension of a container, which is convenient for transportation. Of course, if you really don't want to modify the size, it must be made into a size of 4*3*3m, and we have no problem. Just the shipping cost would be high because the normal container can not load such a huge machine.
At present, the largest walk-in model made by Noki is 600 cubic meters.
(1) Sheet metal type
Sheet metal type is also called library plate type. During installation, the master worker assembles the pieces of the library board together by welding. This method is troublesome to assemble and requires the patience of the worker master to weld the library boards together like building blocks. The advantage is that this way of assembly is easy to transport. Just stack the library boards like furniture and pack them one by one.
This assembly method requires that the master worker has considerable proficiency in welding and is very familiar with the components of the equipment. Higher requirements for workers and masters.
(2) All in one
One-piece, as the name suggests, means that the entire walk-in temperature humidity test chamber is formed in one piece. No need to assemble the library board.
The disadvantage is that it occupies a large area, is inconvenient to transport, and has a high cost.
The advantage is that because it is integrally formed, the sealing is very good, and the heat preservation and moisturizing effect are better. If the customer conducts the high-temperature section test, the equipment will not be cracked due to the presence of welds.
The walk-in temperature humidity test chamber is equipped with forced heating, forced cooling, forced humidification, and forced dehumidification through the air to the working space. The test chamber has an air room, a circulating air duct heating device, a cooling device, a humidifying device, and a circulating fan. Diffuser;
The temperature and humidity controller sends instructions according to the set temperature and humidity, and the temperature and humidity sensor in the test room transmits signals and controls the output of the heating and humidifier through the PID intelligent adjustment and SSR control module, the refrigeration unit works, and the circulating air is evenly distributed.
The top is blown out, and it is recovered from the bottom after passing through the test space to form a closed-loop control mode, so as to achieve the purpose of long-term stable operation.

The interior of the walk-in test chamber is made of 304 stainless steel 1.0mm, and the outer box is made of sprayed cold-rolled plate 1.5mm. A visual window can be added to the door of the test room, which is convenient for operators to observe the interior of the test room.
In order to prevent the chamber body from being deformed, 80# channel steel is used inside the chamber body to strengthen it to prevent the chamber door from being deformed due to excessive weight and affecting the sealing performance.
The insulation material of the housing body is made of polyurethane ultra-fine glass fiber cotton, and the thickness can be customized. The thickness of the current product range is 100-200mm. The thicker the thickness, the higher the price.
Due to the large walk-in, LED illumination is generally standard. Standard 50mm diameter test hole with silicone plug. If the customer has demand, the number of test holes can be increased, which is convenient for testing a large number of samples. Advance notice is required.
The walk-in test chamber is equipped with a touch screen control panel as standard, with a sound and light alarm system and protection system. Pure English operation interface: users can control temperature and humidity, test cycle items, etc, by simply tapping the panel, which is very convenient. The USB export port is under the control panel, which is convenient for customers to export test data results at any time.
The test room can be made into a single door or double door according to customer requirements, depending on customer needs, there is no additional cost.
The water tank is located near the unit cabinet of the whole walk-in test chamber and has water shortage protection. There is a Φ10mm external water inlet in the lower part of the chamber after the inspection. The purpose of the laboratory is unguarded. The test water can be switched between an automatic recovery cycle and no recovery.
