Model Description:

J ": JOSUN logo

“H”： Constant temperature and humidity type

300 ": nominal cooling capacity, in kW

Product composition:

The compression refrigeration unit (refrigeration compressor, finned condenser or water-cooled condenser, control components), refrigeration dehumidification unit (finned evaporator, throttling device), heating components, humidification unit, and air supply section (centrifugal fan and motor) control unit are composed of four main parts. The structural type is frame structure, suction type, and all components are installed on a movable chassis.

Product Features:

The constant temperature and humidity machine adopts intelligent control mode to achieve precise control of indoor environment temperature and humidity by cooling, dehumidifying, heating, humidifying and other functions of the unit. Widely applicable to electronic industry, instrumentation, printing factories, communication equipment, power supply and distribution stations, and other occasions that require high accuracy in air temperature and humidity.

Product advantages:

The device integrates all functional components into one, with the characteristics of numerous specifications, flexible design, intelligent control, high efficiency and energy saving. It is easy to operate, compact in structure, space saving, stable in performance, low in energy loss, resistant to impact and swing, and easy to maintain. The design, production, and acceptance of the device are all carried out in accordance with the specifications and relevant standards of classification societies (such as CCS, ABS, NK, DNV, etc.), and can be customized according to the actual ship type of the customer.
