BE Model – Exhaust Gas Absorption Chiller

BE double-effect absorption units convert the heat of exhaust gases directly into cooling or heating.

Specifications

Cooling capacity: 233 kW – 11,630 kW
Exhaust gas temperature: 280 °C – 532 °C
Exhaust pressure drop: 0.75 kPa – 2 kPa
Functions: cooling or heating

How does it work?

The heat of the exhaust gases, which flow on the shell side of the generator, heats a lithium bromide (LiBr) solution, which releases water vapour. This vapour is condensed by the cooling water, then the water flows into the evaporator, under high vacuum: there it evaporates and cools the chilled water. The vapour is then absorbed again by the solution, which goes back to be heated, and the cycle starts over. Cooling is thus produced with heat, without a compressor.

Key benefits

Bypass valve supplied: it diverts excess heat according to the cooling or heating demand
Hot gases on the shell side of the generator: low pressure drop
PID control for maximum COP at full and partial load
Built-in colour touch screen and monitoring via Modbus RTU, Profibus or TCP/IP
