Coolant Filtration Systems

The C.R.O.S.S. from EdjeTech is the ultimate machine coolant filtration system!

EdjeTech’s C.R.O.S.S is a coolant filter that is used to remove contaminants from your metalworking fluid. Our coolant filtration system will remove the solids and free oils no matter if it is a soluble oil, semi-synthetic, or synthetic machine coolant.

Defining Attributes of EdjeTech’s Coolant Filtration Systems

EdjeTech’s C.R.O.S.S. is an excellent choice in a coolant filter for those facilities that mainly use the same type of machine coolant throughout their shop. The EdjeTech C.R.O.S.S. coolant recovery machine uses a centralized coolant filter that provides clean, fresh coolant 24 hours-a-day for sump clean outs or for a 5-gallon makeup needed at the end of a shift.

Our coolant filtration system includes a proportioner that will automatically mix coolant concentrate and water together to maintain system levels, make sure there is always machine coolant available, eliminates mixing machine coolant by shop associates and the coolant return system will distribute clean coolant throughout the shop via client provided piping.

EdjeTech’s coolant filter incorporates an oil/water separator that uses bag industrial coolant filters to remove solids and coalescing media to remove mechanically dispersed (beaten in oil that is not chemically bonded to the water) and free oils from the coolant. The EdjeTech C.R.O.S.S. coolant recovery machine is sized to handle the volume of the largest sump in the shop and provide enough coolant to refill that sump immediately. No waiting!

Working with EdjeTech’s Machine Coolant (C.R.O.S.S.) Filtration Systems

The best fluid maintenance solution for a facility is to get on a regular sump clean out procedure using the EdjeTech C.R.O.S.S coolant return system. This is not as daunting a task as it seems if proper instruction is followed. For example, a shop might be cleaning out their sumps every six months because the coolant smells or is too dirty to perform well.

Using the C.R.O.S.S. coolant recovery machine, this same company could eliminate coolant disposal by setting up a schedule to regularly remove the coolant from the machine sumps, send it to the C.R.O.S.S. and recharge the sump quickly with the clean coolant that is available to the shop floor 24 hours-per-day via the coolant return system. This is not a complete sump clean out; it is only the removal of coolant and recharge. This schedule will also help in speeding up that half year or yearly heavy clean out of sumps because dirt and oils will have been removed regularly with the help of the coolant return system.

Increase YOUR production through waste minimization, invest in EdjeTech’s efficient machine coolant filtration systems today.

Our Coolant Filtration Systems Reduce:

  • Waste disposal costs by 85% to 90%
  • New fluid purchases by 45% to 80%

The system payback is typically 3 to 9 months. Stop throwing away your coolant!

The EdjeTech C.R.O.S.S. coolant filtration system removes tramp oil to less than 1/4 of 1% by volume, suspended solids to acceptable levels, maintains adequate supply of clean coolant at ALL TIMES, free-oil removed by the system has less than 2% water content, operates automatically, minimal maintenance, and is a compact, self contained machine coolant filtration system.

"Very reliable units. We have many of your units in service."
