Product Description

Product Introduction

The HQ-ES4 series of thermal control fluid for energy storage batteries is an ultra-low conductivity coolant refined from polyester-grade ethylene glycol, non-ionic inhibitors, and antioxidants. The freezing point of this product can be customized, with a range of -60°C to -20°C; operating temperature range: -55°C to 120°C. This product is a pre-diluted coolant and can be used directly.

It is suitable for temperature control system in high voltage environment such as high voltage cascade storage battery and high voltage SVG.
• Excellent electrical insulation performance ensures the operational safety of energy storage power stations;
•Outstanding metal anti-corrosion performance and non-metallic compatibility extend the service life of the temperature control system in energy storage power stations;
• Ultra-long service life reduces maintenance costs for energy storage power stations;
•Superior freeze protection performance prevents equipment damage caused by liquid freezing and expansion;
•Excellent environmental performance, free from inorganic salt components such as phosphorus, amines, nitrites, nitrates, and molybdates;
•Complies with EU regulations such as RoHS and REACH.
