Eco-solution 2: Reuse of Water Condensate Presentation of Data

Water condensate is extracted from the air as a by- Based on the environmental review data, we estimate

Review of Eco-Solutions by
Excess condensate can also be used: SME Management

• To wash the shop floor; Our eco-solutions were presented to the management
of CKE Manufacturing.
• To mix with cutting fluid for use in machinery
operations; • The management approved the cost savings
associated with the modification of the air-
• As a dielectric fluid for use in EDM wire-cut conditioning system. This also results in 17 %
