Drying Walk In Environmental Chamber

Drying Walk In Environmental Chamber


Dry walk in environmental chambers are a special type of walk in environmental chamber specially designed for drying or dehumidification applications. These chambers provide controlled conditions to remove moisture from products, materials or samples. JOEO Drying Walk in Environmental chamber are ideal for automotive, computer, battery, defense and other industries
According to market demand and customer requirements, JOEO has extensive experience in battery testing technology, JOEO has configured dry walk in test chambers for battery production to meet low humidity, such as 5%R.H -10%R.H. A continuously dry indoor climate is one of the key technologies in the production of high-performance lithium-ion batteries for electric drive.


Drying Walk In Environmental Chamber structure

Interior material: SUS # 304 stainless steel plate (1.5 mm thickness ).
Exterior material: cold rolled steel, galvanized anti-rust treatment with advanced resin paint coating.
Insulation material: German Bayer fire-resistant high-strength PU polyurethane foam insulation material +ultra-fine glass fiber.
Heat preservation material: imported rigid rock wool rock wool (CSR 120 k).
In addition, in order to prevent glass frosting when running low temperature, we setup a heating wire inside to get it de-frosting.
Both sides of chamber are equipped with a test cable port with diameter 100mm, the silicon plug is with high low temperature resistance.
Heater: Fin type radiator pipe shaped stainless steel electric heater.

Details for Dry Rooms Technical 

JOEO walk in test chamber reduction of humidity in production facilities is the key to long-lasting and powerful lithium-ion batteries.  Dry Rooms with dehumidifier system air in battery cell production to a residual water content of up to 0.001 grams per kilogram of air. This corresponds to a dew point of -70 degrees Celsius.  To keep the production climate constant under all conditions, the battery cell production chambers are hermetically sealed off from the outside climate. JOEO Dry walk in environmental chamber first cool down the ambient air in the production area, whereby a large part of the moisture condenses. Second, specially coated drying wheels remove the residual moisture until the desired value is reached. To keep the climate in the drying chamber system constant under all conditions, the system generates a slight overpressure. 

CO2 Protection System

The system is equipped with a control unit, an alarm panel, an emergency button,a thermostat with dedicated temperature probe and a system with a CO2 fire extinguishing system;
The CO2 system is activated by exceeding a temperature threshold (settable by the user) measured by a dedicated PT100 or by exceeding the CO2 threshold inside the chamber;
The detection system, provided with its own power supply, activates the CO2 in the chamber;
Fire suppression systems inert atmosphere uses N2 or CO2 to eliminate Oxygen.

Electrical System

The overall layout of the circuit cabinet looks very neat and professional. Our circuits are arranged in accordance with UK standards and are equipped with complete circuit diagrams. Each line has a unique code, which is clearly defined and easy to locate for troubleshooting.
We use electrical components of world famous brands, such as Schneider from France,Carlo Gavazzi from Switzerland,Mitsubishi from Japan,Rainbow from Korea.
