Storage Control Systems, Inc. has long been a producer of efficient Carbon Dioxide Scrubbers for CO2 control inside Controlled Atmosphere storages. The massive success of our eIII Scrubbers has spawned the Series IV , bringing greater control to the next generation of SCS Scrubbers.

Updated features begin with gas sampling of the lines for smart scrubbing control. Our new Pre-Scrub option evacuates the main trunk lines into a standard CA room prior to initiating a scrub cycle on a DCA or ULO room. Doing this prevents stray O2 in the lines from disrupting levels in sensitive rooms where control is key. Another new feature is MultiQueue, which allows multiple rooms to sequentially share the same scrub cycle, helping to keep room levels more consistent, as well as helping to reduce the number of complete scrub cycles required of a machine.

As always, the operator interface allows for easy programming of unique facility room numbers & settings/ alarms, CO2 concentrations for peak performance scrub and purge times, background timing defaults, CO2 scrub cycle history, log of CO2 levels, scrubber capacity ratio, single or multi-room sequencing, as well as auto room pressure testing. Oxygen Control is also a feature for the smaller warehouse operator.

Large models feature Variable Frequency Drives‡ to insure maximum efficiency CO2 adsorption for various warehouse installations across the world. Neither 50Hz or various piping should change the adsorber characteristics.

As the scrubber reduces the CO2 in the room, the cycle time adjusts accordingly making the scrubber more efficient each cycle. This ultimately will reduce your cycle times and make the oxygen in the room easier to control. ULO is easily achieved on SmartFresh treated rooms.
