Walk-In Comprehensive Chamber
(temperature, humidity, ethylene glycol temperature, flow rate, pressure control)
Walk-in chamber for battery test
Application：
Suitable for the battery, provide constant temperature and humidity environment, give the battery a constant flow rate, pressure, temperature of ethylene glycol aqueous solution, flow cooling heating temperature control is used in the internal battery.
Product overview:
Wide temperature control range, from 45 ℃ to 100 ℃, can satisfy the user's very steep temperature gradient and other requirements.
With a unique balanced temperature control method, a stable and balanced heating capacity can be used for high precision and high stable temperature control.
The temperature is displayed by touch screen, easy to read, precise and convenient.
With high temperature starting function, the chamber can be turned on when the temperature in rises to 100 degrees. It is convenient for continuous round-trip test between high temperature and low temperature.
With self-diagnosis function, overload protection of freezer, high pressure switch, overload relay, thermal protection device, etc.
With multi-wing fan used to circulate and avoid any dead Angle, so that the temperature can be distributed evenly in the test area.
he air circuit is designed with the wind return wind, the wind pressure and wind speed are in accordance with the test standard, and can make the opening instant temperature regain fast.
Heating, cooling, and completely independent system can improve efficiency, reduce test cost, increase life span and reduce failure rate.
The water tank is placed in the lower right part of the control box with water shortage and automatic protection.
The humidifying system is separated from the control circuit board, which can avoid the failure of water leakage in the humidified pipeline and improve the safety.
The channel system of waterway system adopts door opening, maintenance easily.
In the refrigeration system, the condensation adopts air cooling mode or water cooling mode, and the temperature control device can be flexibly connected with other test platforms.
Strong circulating pump while ensuring the delivery of high viscosity liquids.
Adopt proportional control valve control flow output, achieve high precision control total range 10% ~ 100% adjust.
The ethylene glycol refrigeration heating system USES a fully closed circulation system, thus avoiding the opportunity of the antifreeze and outside air contact, ensuring that no water vapor condenses and the service life is long.
The control temperature is accurate up to 0.1, the visualization operation is safer and simpler, and the data storage and report analysis are more convenient.
