Product overview and usage
This product uses circulating air for constant temperature drying, with a high degree of intelligence, no need for special supervision, and the temperature is adjusted according to the user's intelligent automatic control, so as to achieve the drying effect in the shortest time. Its working temperature can be from room temperature to the maximum, and the working temperature can be arbitrarily selected within this range, and the temperature can be kept constant by the automatic control system in the box after selection. It is equipped with an electric blower to promote the mechanical convection of indoor hot air and make the indoor temperature more uniform.
Performance indicators
Note: When the ambient temperature is +5~+35°C, the performance is stabilized for 2 hours without test load. In addition, the temperature rise and fall time refers to the performance of the power supply voltage with a normal supply voltage and an ambient temperature of +25±5°C.
Equipment structure
This equipment is composed of imported high-quality library board, and the high-efficiency insulation cotton is used as the insulation layer material between the studio and the box shell, which has good insulation effect and is safe and environmentally friendly. Open the exhaust valve on the top of the box to exchange the hot and cold air in the studio, and the temperature control is automatically adjusted by the thermal expansion controller or digital display instrument. All electrical operating equipment is installed in the control layer on the side of the box. There are side doors in the control level that can be removed for inspection or repair of wiring.
