Lamp arrangement

Radiation Heating System

Adopt scale-type heating tube, multi-wing centrifugal fan air supply loop, temperature controller output control contactless SSR, achieve temperature balance, long-term stable operation

Condensation heating system

The heating method is steam heating, and the nickel-metal alloy heating tube P.I.D controls the heating to achieve temperature balance.

Water supply system

Manual and fully automatic water supply control systems are available. Just connect to the water pipe for automatic control, easy to use.

Note: If the tap water has too much impurities or is acidic or alkaline, a screening program needs to be installed at the water inlet.

Drainage system

Drain valve control device, manual drainage mode

Automatic over-water overflow control system

Spray system

A booster pump is used to control the spraying water pressure.

The spraying time and spraying cycle are fully automatically controlled. Accurate over-water overflow device
