The Castair RDDMLT is an accessory for Castair RDD series refrigerated compressed air dryers. The MLT suffix suggests this is a multi-line timer or a manifold-line timer component — an electronic or mechanical timer control used in conjunction with the dryer's drain circuit or operational controls. In refrigerated dryer applications, timer controls govern automatic drain cycles when demand-based drain sensors are supplemented or replaced by timed drain functions, or coordinate multi-dryer or multi-line drain sequencing in larger installations.
If your RDD series dryer installation requires coordinated drain timing — multiple dryers on the same compressed air system, drain sequencing to avoid simultaneous air loss, or a timer-supplemented drain circuit for high-condensate environments — the RDDMLT is the Castair-specific component for that function. Call 866-217-0063 to confirm whether this accessory is appropriate for your installation and how it integrates with your specific RDD dryer model.
Typical Applications for Timer/Control Accessories on Refrigerated Dryers
- High-condensate environments: Shops with high ambient humidity or high air demand where the demand drain cycles very frequently — a supplemental timer can be used to ensure regular drain intervals during sustained high-humidity operation.
- Multi-dryer installations: When two or more dryers serve the same system, staggered drain timing prevents simultaneous air loss from multiple drain valves — coordinated by a multi-line timer.
- Override or backup drain timing: If the primary demand drain sensor fails or is bypassed for service, a timer control provides a reliable backup drain cycle to prevent moisture buildup.
- Scheduled maintenance intervals: Some shops prefer timed drain control for predictable air loss planning in production environments.
