Modified Atmosphere Refrigerator - QT300

Hardware and software

• The product consists of controlling section, implementing section and workroom. The control section can set a variety of parameters (including temperature, humidity, gas concentration, etc.), to meet the growth requirement of different animals and plants and the preservation needs of various living things.
• Three test chambers. Each chamber independent controlling system, illumination system and sterilization system (With ultraviolet disinfection and ozone sterilization function).
• The workroom is made of stainless steel plate with surface of spray plastics, so it is of great antirust performance.
• Imported precise sensors ensure wide test range and high accuracy.
• Configured with: transparent window, sterilization system, built-in headlight and self-occlusive design cabinet.
• Can automatically record the respiratory status of fruits and vegetables and check data handily. Computer-controlling system is optionally available and can save historical records.
• Real color touch screen displays the parameters and results visually.
• With software, real time monitor and continuous record of gas composition, temperature and humidity; can achieve distant monitoring.
• Online analysis system is optionally available.

Temperature control

• Adopts quartz tube to heat up and scroll compressor to cooling down, so the temperature can be risen and lowered quickly, with high performance and little noise.

• PID algorithm works together with solid relay to control the heating tube, controls the temperature precisely, evenly and constantly, without rigid mechanical contacts and with long lifetime.

Humidity control

• High-frequency atomization humidification provides large humidification range and stable humidity. Can humidify for a long time without getting hot.

• The humidifying system of each chamber works independently. Automatically humidifies after setting the humidity parameters, reach the set humidity and stay at that humidity constantly. 

Gas control

• Automatically control the concentration, temperature and humidity of the gases.
• Accurate flow controller (resolution ratio: 0.01ml/min) controls the gas flow exactly.
• With ethylene eliminating device and gas substituting pump, controls the concentration of ethylene effectively.
• Two ways to provide nitrogen: gas cylinder or nitrogen generator. High-power nitrogen generator (3 m3/h, purity>99.5%) is more cost-saving.
• Auto replacement of gas, fast removal.
