|Benefits of Recycling your coolant:||Features of the 'Guardian''|
About Coolant Recycling & Operation of ‘Guardian’ System:
With coolant concentrates running $500 per drum and waste hauling fees increasing, the need for a recycling program becomes quite obvious, the added pressure of ISO 14,000, waste minimization programs and quality control issues also compel companies to investigate recycling. Unless your company has money to burn, pure economics dictate that you run coolant as long as possible to avoid the cost of haul away and new coolant, that’s usually several weeks after the smell starts. In the meantime the coolant has become loaded with solids and/or tramp oils, these contaminants have a direct impact on the quality of your finished part. Effective recycling is the removal of contaminants and the subsequent prevention of bacteria, leaving you with clean coolant ready for reuse.
Since we don’t sell coolant we really don’t want you to dump it. We offer the ‘Guardian System’ to help you accomplish your goals, the ‘Guardian’ utilizes a coalescing separator rather than a centrifuge, the centrifuge tends to remove coolant concentrate costing you money. The ‘Guardian’ system operates independently of the coolant sumps, therefore the movement of coolant to and from the system becomes the first issue. Ideally a sump sucker is used, if you’ve never seen one picture a propane tank on wheels with an electric or air operated pump (see our sump cleaner section). The sump cleaner is sized to hold the entire contents of one or several sumps, they range in size from 60 gallon single tanks to units with two compartments (clean & dirty) each holding several hundred gallons. The power of the sump cleaner means it can pump at 100 gpm, it’s quick and also removes the sludge and slime from the bottom of the machine sump, this is critical to an effective recycling program. Let’s say, for example, that your machines hold 50 gallons of coolant each and we’ve supplied you with a ‘Guardian’ recycling system that has a 200 gallon clean and a 200 gallon dirty tank, and a sump cleaner that has a split tank, each tank hold 100 gallons.
As mentioned above, the clean tank of the ‘Guardian’ recycling system is full and overflowing into the dirty tank that is 25% full, that means there is 200 gallons of clean coolant ready for use and room to add 150 gallons of dirty coolant. When the time comes to clean a machine sump the operator gets the sump cleaner and first goes to the ‘Guardian’ system, he (or she) pumps 100 gallons of clean coolant into the clean compartment of the sump cleaner, the sump cleaner is pushed to the machine sump, the dirty coolant is then pumped into the sump cleaner and clean coolant is then pumped from the sump cleaner into the machine sump, machine downtime is about 10 minutes.
The sump cleaner now holds 50 gallons of clean and 50 gallons of dirty coolant, he then proceeds to the next machine and does the same thing, he then returns to the ‘Guardian’ with 100 gallons of dirty coolant and pumps it into the dirty side. It sounds confusing but it’s really simple. We have many reference accounts that will verify that this method of coolant recycling really works, call us.
