Working noise

A sound level≤70dB(A)

(Measured in a soundproof room with an ambient temperature of 25°C and low echo. Using A weighting, test the average of 9 points. Each test point is 1 meter away from the noise source horizontally and 1 meter above the ground.)

Insulation enclosure structure

1. Outer wall material: A3 board spraying.

2. Inner wall material: brushed stainless steel plate SUS﹟304.

3. Chamber thermal insulation material: 100mm high temperature resistant rigid polyurethane foam.

4. Chamber door insulation material: 100mm high temperature resistant rigid polyurethane foam.

Bottom structure strength

The weight capacity of the track at the bottom of the test chamber: ≤100Kg/m² (load)

Air conditioning channel

1. Stainless steel long-axis centrifugal fans: 4 sets/90W.

2. Fan, heater, evaporator (also dehumidifier), drainage device, pressure balance port, adjustable air deflector, temperature sensor

Standard configuration of test chamber

1. Observation window: 400x600x40mm 3-layer vacuum tempered glass

2. Flat embedded handles

3. Door hinges: SUS #304 imported hinges

4. Energy-saving lamp inside the chamber

5. Lead hole: φ100mm 1 piece

Chamber door

1. The single-piece door opens outwards, with the hinge on the left and the handle on the right (when facing the front of the box).

2. Equipped with a safety door locking mechanism (the door can be opened in the test room), the door is equipped with electric heat to prevent condensation, and the visible range of the insulating glass observation window (W400×H600mm). The door frame is equipped with an anti-condensation electric heating device.

Explosion-proof pressure relief port

The equipment is equipped with one explosion-proof pressure relief port on the left side, measuring 300mm × 300mm. When the internal pressure of the chamber is ≥0.104MPa, the pressure relief port will automatically open.
