Energy efficient – Powerful – Flexible
Equipped with a modern 3D- Polyamide propeller, our most energy-efficient model meets even the toughest requirements.
A propeller with 5 years warranty, 360 degree adjustability and effective 100 rpm – the Compact convinces in many ways.

Dimensions you can find at Arma Mix COMPACT Data sheet or Arma Mix COMPACT Flyer
Advantages
- Electrical drive is located outside the tank – thus easy maintenance
- Ex – Zone 2 approval
- Swivel axis is outside of the tank
- The drive shaft with multiple bearings lubricated for life
- Suitable for concrete, steel and enamel tanks
- Ceiling installation or installation through the tank wall possible
Double corrosion protection
- Galvanized
- Teerepoxy – coated
- or in AISI 304 or AISI 316 available.
‘Easy mounting – A gas-tight base frame is attached at the agitator, which is screwed onto the concrete frame. This is firmly anchored in the tank.
High stirring performance and excellent mixing – with short running times
- High efficiency at different dry matter content
- Designed for 24 hour operation
- Large swivel range – effective agitator length in the tank up to 4.0 m: can be infinitely adjusted during operation, depending on substrate composition, quantity and dry matter content, as no bottom bearing is required.
- Motor power selectable from 7,5 – 15,0 kW
- 3D- Propeller made of polyamide can be used at a bacteria-friendly speed of 100 or 200 rpm.
- Push propeller with 5 years wear guarantee
