LRS4.0

Dedicated system for coolant cleaning and recycling, extending fluid life and reducing disposal costs

LRS4.0

Automatic Coolant Recycling System

LRS4.0 is D&P Group’s automatic coolant recycling system designed to recover, treat, and reuse exhausted coolant from CNC machine sumps.
The system removes contaminants, separates tramp oils, reduces bacterial growth, and restores the main coolant parameters, helping manufacturers reduce disposal costs, water consumption, and environmental impact.

Product Overview

In modern machining processes, coolant gradually becomes contaminated by metal particles, tramp oils, sludge, bacteria, and process residues. If not properly managed, exhausted coolant can generate unpleasant odors, increase disposal costs, affect operator health, and create environmental issues.

The LRS4.0 has been engineered to improve industrial fluid management through an automated recycling process. It collects used coolant from individual CNC sumps and processes it through filtration, decanting, oil separation, disinfection, oxygenation, and parameter restoration.

Key Benefits

Benefit

Operational Impact

Reduced disposal costs

Less exhausted coolant sent to disposal

Lower waste volume

Only solid waste and oily waste are separated and disposed

Reduced water consumption

Treated coolant can be reused instead of fully replaced

Improved workplace hygiene

Less odor and bacterial contamination

Reduced storage space

Less space needed for exhausted coolant collection

Lower maintenance labor

More automated fluid management

Environmental improvement

Lower impact from coolant disposal and water use

Sustainability support

Useful for companies pursuing environmental certifications and Agenda 2030 goals


Waste Separation

The LRS4.0 process is designed to separate what cannot be reused from what can be recovered. Waste materials such as metal chips, powders, sludge, tramp oils, cutting oils, protectants, and other pollutants are collected in dedicated containers that can be emptied and sanitized.

Waste Type

Management Method

Metal chips

Separated and collected

Metal powders

Removed through filtration

Sludge

Settled and removed

Tramp oils

Separated through coalescence

Hydrocarbons

Removed from coolant flow

Cutting oils and protectants

Collected as oily waste

Reusable coolant fraction

Treated and restored for reuse


Sustainability

LRS4.0 supports a more sustainable approach to industrial coolant management by reducing disposal volumes, lowering water consumption, and improving waste separation. Since approximately 90 liters out of 100 liters of exhausted coolant can consist of water, proper treatment allows a significant portion of the fluid to be recovered instead of disposed of.


⚠️ Important Notice

LRS4.0 is not a water purification system.
It is an industrial coolant recycling system designed specifically for the treatment and reuse of metalworking fluids.
