Sterling SIHI’s standard modules include liquid ring vacuum pumps complete with a motor, service liquid separator, base plate and pump support stool. The Sterling SIHImodular is used in an extensive range of applications and design options, including closed circuits with heat exchangers or liquid make-up facilities without heat exchangers. To meet the duties of the different applications, these systems offer eight pump sizes, each with a wide range of design options. Thermostatic control of the cooling water and service liquid maximises the cost benefits through reduced energy consumption. These modular vacuum compact systems are designed for ease of operation and increased safety for any applications.
