Feature description

The box body is processed by CNC machine tools, with beautiful and elegant appearance, and adopts non-reaction handle, which is easy to operate.

The inner tank of the box adopts imported high-grade stainless steel (SUS304) mirror panel. The outer tank of the box is sprayed with A3 steel plate, which increases the appearance and cleanliness. The operator replenishes water. The large observation window with illumination lamp keeps the inside of the box bright, and the embedded tempered glass inside the heating body is used to clearly observe the conditions inside the box at any time.

The separation of the humidification system piping and the control circuit board can avoid failure due to water leakage in the humidification piping and improve safety.

The water circuit piping circuit system is convenient for maintenance and repair.

The box insulation uses ultra-fine glass fiber insulation cotton to avoid unnecessary energy loss.

The left side of the cabinet is equipped with a test hole with a diameter of 50mm, which can be used for external test power lines or signal lines.
