The cooling circuit of the 200 m3fermenter consists of centrifugal pumps (Sigma, tape NFT) and plate exchangers (Maschine Works Chotěboř). The best function of this circuit was achieved when the medium was taken of from the place with the lowest gas hold-up in the fermenter. The pump function and the broth discharge rate is constant with the hold-up of air up to 35 %. Under these conditions the pressure loss of the plate exchanger remains up to 0,15 MPa at he flow rate of 300 m3.h-1. The plate exchanger used for the cooling has a high value of the heat transfer coefficient above 2500 W.m-2.K-1.
