420B Evaporators

420 Evaporators

The 420B Evaporator is mounted on a boom platform and base which raises and lowers and can be aimed at differing horizontal and vertical angles. The standard unit is constructed with galvanized steel.The 420B Evaporator has a stainless steel coated, easy to use jack and a stable free-standing concrete counterweight system. Stainless steel fasteners and safety chain are standard. A customized material construction is available upon request.

The SMI 420B Wastewater Evaporator has the following features and benefits:

420B Evaporators

HIGH PERFORMANCE

A high speed fan blade rotating at 3600 rpm creates an optimum water droplet distribution for evaporation. Average annual evaporation rates up to 70% have been achieved with rates typically between 25-to-60%, depending on factors such as ambient temperature, relative humidity, water make-up and wind conditions. In general, the warmer and drier the conditions, the higher the evaporation rates achieved.

LOW PRESSURE

The SMI 420B Evaporator operates successfully between 20 and 100 psi water pressure.

LARGE ORRIFICE SIZE

The SMI 420B Evaporator can pass particles up to 3/16 (5mm) in diameter. This eliminates the need for pre-filtering, filter cleaning and the hassles of clogged nozzles.

EXTREME DUTY

The SMI 420B Evaporator design has evolved from 20 years experience in industrial and extreme outdoor applications.

SIMPLE OPERATION

The SMI 420B Evaporator can be operated in the vertical upright or angled over the pond by manually lowering or raising the boom. The machine can be operated in any wind condition as it is not sensitive to blowback.

EASY MAINTENANCE

The machine is easy to clean and maintain by design. There is no weekly greasing of bearings.

OPTIONS

For acidic or high alkaline water applications or a highly corrosive environment, SMI offers an upgraded version with chemical resistant coating on the boom, platform and base frame. Alternatively, the boom can be produced with stainless steel.
