ARMA MIX COMPACT

Energy efficient – powerful – flexible

LONG-SHAFT AGITATOR - ARMA MIX COMPACT

Equipped with a modern plastic propeller, our most energy-efficient model can withstand the toughest demands.

Advantages of the ARMA MIX COMPACT

For side & ceiling installation in 7.5, 11.0 or 15.0 kW.

A propeller with a 5 year warranty, 360 degree adjustability and an effective 100 revolutions per minute – The Compact convinces in many ways.

Easy installation – A gas-tight base frame is attached to the agitator, which is screwed onto the embedding frame. This is firmly anchored in the tank.

High stirring performance and excellent mixing – with short running times.

Easy maintenance thanks to electric drive located outside the tank
Ex – zone 2 approval
Swivel axis is outside the tank
The drive shaft with multiple bearings runs in an oil bath
Suitable for concrete or steel tanks
Ceiling installation or installation through the tank wall possible

Double corrosion protection
Hot dip galvanizing
Tar epoxy coating or in V2A or V4A design
