The ACS Customer Service Group is pleased to be able to offer our customers preowned and older model equipment at a fraction of new equipment pricing. All items are thoroughly inspected by the factory prior to shipment and in many cases carry warranties of up to one year. Purchases of preowned or older equipment through the ACS Group of companies entitles you to the level of support only provided by the ACS Customer Service Group. Such support is not available when purchasing through used equipment dealers or brokers, as they do not have access to your unit's manufacturing drawings or bills of material. Process Categories:
