asphalt heater

Asphalt Heaters
This heat-exchanger unit heaters is designed for rugged industrial applications for hot-oil, steam, water, glycol circulating heating systems.

To heat bitumen supplies, using in continuos or batch blown units from 120ºC to 200ºC, with hot-oil.

The frost resistant series is designed primarily for steam applications that are subject to freezing conditions. The high-pressure series is designed for pressures to 400 psi in single-pass and multi-pass configurations. Multi-pass units greatly improve performance with liquids. The series both have a 1-year warranty.

The specific heat of bitumen is as follows:

ºC	KJ/kgºC	cal/g/ºC
0	1.67	0.4
100	1.89	0.45
200	2.10	0.5
