Designed especially for solvent distillation / evaporation applications, the LVS ecoflex+ systems comprise of a chemical duty diaphragm pump with VCpro digital vacuum controller, liquid separators and exhaust emissions condenser for optimal solvent recovery. Designed for chemical applications all wetted parts are made from high quality chemically resistant materials, with clear plastic coated glassware. The VCpro digital vacuum controller with ecoflex control philosophy continuously adjusts the pumping speed to match the vapour load produced by the evaporation process to give a fast and efficient process without bumping or foaming.Analytically pure, oil free vacuumHighly chemical resistantUltra quiet operation - silent at equilibriumPrecise vacuum control with timed ramp capabilityFully programmable modes to allow run repeatabilityEcoflex vacuum control for optimised evaporation and energy efficiencyIntuitive ICON-navigation of control screensConnectivity through LAN and RS232Built-in self-cleaning functionSecurity levels for administrators and usersLog files on all pump activities for easy traceabilityHigh-Res display with dark and light screen modesDigital and analogue vacuum pressure displaySpecificationsPump speed 50/60 Hz:Final vacuum (abs.):2 mbarOperating Temperature Range:15 ... 30 °CSuction / pressure connection: Inert Gas Port to Release Valve:DN8 DN4Noise:IP code:IP 20
