The SMI 420F Evaporator is our floating unit supported by close celled foam containing plastic pontoons. It has a low plume height for shorter drift distance of droplets and to allow longer operation in swirling or constantly changing winds. The 420F is made of heavy industrial construction for durability and long life, including a stainless control panel, motor enclosure, manifold and fan blade. The vibration sensor shuts down the motor before a catastrophic failure due to residue or ice build-up. The SMI 420F Evaporator provides many advantages versus competitive products.

HIGH PERFORMANCE

High speed fan blade rotation (3600 rpm) that creates an optimum water droplet distribution for evaporation. Average annual evaporation rates up to 70% have been achieved with average rates typically between 25-to-60%, depending on many 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.

LARGE ORIFICE SIZE

The SMI 420 Floating 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 420 Floating Evaporator design has evolved from 20 years experience in industrial and extreme outdoor applications. The polyethylene plastic pontoons are filled with close celled polyurethane foam, ensuring buoyancy even after any accidental puncturing that may occur of the plastic outer shell. Critical components are constructed of stainless steel for extended life in harsh environmental conditions.

EASY MAINTENANCE

The machine is designed for easy cleaning and maintenance. The unit requires 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.

SMALL FOOTPRINT

The SMI 420 Floating Evaporator doesn't take up extra room around the pond and is designed with minimal amount of top surface area for residue or ice to build up. There is little cleanup or maintenance required.
