The claim to the novelty is:

a. Extraction of the exhaust vapors from the expansion vessel of the preexpander, in order to recover the thermal energy, which would otherwise be lost
b. Noise level reduction by eliminating evaporation over the roof
c. Prevention of contamination of the air and the surrounding area by polystyrene dust, remains of coating material, escaping blowing agent (pentane) and residual styrene
e. Use of the negative pressure in the expansion vessel to decrease the temperature of the steam in such a way, that densities of over 25 g/l can be processed with a constant flow, saving enery by decreasing the volume of compressed air : no high density unit required to cool down the steam.

In order to achieve this, a device must be installed in the exhaust steam chimney of the preexpander, that enables a connection to VIRO's central vacuum system and ensures, that an appropriately controllable negative pressure is available at all times, which removes the exhaust vapors from air, condensate, residues of blowing agent etc. into the condenser of the vacuum system. The extracted energy is now stored in the water of the vacuum condenser and the impurities and residues of blowing agent are washed out. The energy stored in this way can be used for heating purposes in a separate circuit, using a water/water or water/air heat exchanger. The extracted blowing agent and residual styrene gases are discharged on the pressure side by the vacuum pumps.
