Index Sensors and Controls has introduced a new air conditioning monitoring and protection system designed to reduce maintenance costs and vehicle downtime. The ACX-10 Air Conditioning Life Extender consists of compact control module which is easily mounted in the engine compartment. The system protects air conditioning components against premature failure by monitoring refrigerant pressure and voltage. Both high and low refrigerant pressure can lead to rapid cycling of the A/C system, causing premature wear of the compressor, clutch, and hoses. Under such conditions, the ACX-10 prevents rapid cycling of the A/C clutch by slowing down the cycle rate to 15 seconds, cutting cycle frequency by as much as 80%.
