UVB-1 bitumen unit is designed for production both anionic and cationic bitumen emulsions, which are used in road construction as follows:
base coat on old road top before application of asphalt-concrete;
preparation of cold asphalt concrete mixes;
surface treatment of road top;
thin film protective coats;
patch repair of roads etc.

The unit is designed for operation at asphalt concrete production facilities. It can be operated either outdoors under canopy or indoors.

UVB-1 bitumen unit is semi-automatic, consists of several individual assemblies on a single frame and interconnected by pipelines.

An external source of 6 – 8 bar compressed air is required for operation of pneumatic systems of the unit.

The unit if also equipped with temperature and pressure sensors. Pressure and temperature are measured in the following points:
water/blend supply;
bitumen supply;
bitumen to mixer supply;
emulsion output.

Pressure is measured in the following points:
before the unit;
after bitumen pump;
before the mill.

The unit is equipped with an emulsifier tank heater:

The heater is a welded flat platform. A 200 liter emulsifier barrel is placed on the platform. A heating agent circulates through pipes in the platform.

The control panel is an air-tight metal case containing «Schneider zelio» controller, multifunction measuring regulators TC4 and TK4, protection and start equipment.
