Critical Systems’ Callisto Dry Scrubber is a highly advanced Abatement System that provides Guaranteed scrubbing of the Target Gases to levels well below the (TLV) Threshold Limit Values. With medias blended specifically to the gases and flow rates of your unique process applications, the Callisto utilizes both Chemisorption and Catalytic medias to assure the maximum abatement of the process gas stream. Custom blending also ensures that adsorbents are not poisoned or fouled since potential poisons and fouling agents are removed before they can harm the media.
The Callisto’s sophisticated control system operates the canisters to peak efficiencies to assure the longest life of the canisters at the lowest destruction temperatures, while automated purge cycles insure that the canisters are safe to remove when it comes time for replacement. The Callisto’s controller also maintains a history of all scrubber alerts, temperatures and exhaust concentrations to verify performance and compliance with regulations.
The Callisto’s Dual Canister option employs two canisters and logic controlled bypass valves to continually direct exhaust to the canister with the highest state of readiness, or can be set to operate in an oscillation mode where the canisters share duty with temperature scheduled switching to maximize canister life.
