CREGUARD – Cooling System

CREGUARD – Chemicals for Recirculating Cooling System

 What is CREGUARD?

CREGUARD chemicals are developed to protect your recirculating cooling system from corrosion, fouling, and scaling problems. CREGUARD provides total solution for your cooling system.

Key Benefits of our CREGUARD

• Higher system efficiency, cost saving
• Prevent corrosion, fouling, scaling problem
• Lesser power consumption, lesser water consumption

CREGUARD for Open Recirculating Cooling System

Microbiological problems are common in open recirculating cooling system without proper treatment. The growth of microorganism leads to many other types of problems such as: fouling, scaling, and corrosion. Our CREGUARD provides total solution for your open recirculating system:

+ Antiscalants to prevent scaling problem
+ Metal corrosion inhibitors to minimize corrosion
+ Selections of biocide to eliminate microorganism

CREGUARD for Closed Recirculating Cooling System

Closed system are prone to corrosion because it usually operates at low langelier saturation index by nature. Our CREGUARD for closed recirculating system is formulated to minimize corrosion rates of mild steel and copper that are commonly used in the system.

+ Best in class corrosion inhibitors
+ Higher stability, lesser dosage
+ Compatible with selections of biocide

Cleaners for Recirculating Cooling System

Over time, cooling system loses its efficiency due to the fouling and scaling potential of recirculated water.

Selections of CRECLEAN are developed to address this problem. Each unique CRECLEAN is designed to provide proper cleaning mechanism.

+ Eliminate existing scaling problem
+ Prepare and passivate the surface of your metals + Improve heat exchange capacity
