H/D Coolant Maintenance System

The Flo-Dynamics CMS-240 Coolant Maintenance System, with dual 40-gallon tanks, allows a technician to quickly drain, fill or exchange coolant from large capacity cooling systems in minutes without the need to air bleed. Using push/pull technology, the CMS-240 simultaneously uses pressure and vacuum, speeding up both the draining and filling processes. Refilling without the need to spend hours bleeding air from a cooling system is easy, using push/pull technology and a vehicle’s Flush-Face Quick Connect Coupler cooling system adapter. Without the need to use a drain pan, you can safely and quickly drain a 14-gallon cooling system in approximately 10 minutes, and refill without air pockets in approximately 13 minutes. With two tanks — one for “used” and the other for “new” coolant — a technician can fully exchange coolant in a 14-gallon system in less than 14 minutes without the need to switch hoses or perform hours of bleeding air. The CMS-240 will save repair time costs while creating a safer shop environment by preventing coolant spills.
