Product Description

Product Introduction

The HQ-ES2 series of thermal control fluid for energy storage batteries is refined from polyester-grade ethylene glycol, composite corrosion inhibitors containing organic carboxylates, antioxidants, and pH stabilizers. The freezing point of this product can be customized, with a range of -60°C to -20°C; the operating temperature range is -55°C to 120°C. This product is a pre-diluted coolant and can be used directly.
Applicable to temperature control systems for energy storage batteries.
•Excellent thermal conductivity, enhancing the temperature control level of energy storage station's constant temperature system;
•Outstanding metal corrosion resistance and non-metallic compatibility, extending the service life of the temperature control system in energy storage stations;
• Service life of up to 15 years, reducing maintenance costs for energy storage stations;
• Superior freeze protection performance, preventing equipment damage caused by liquid freezing and expansion;
•Exceptional environmental performance, free from inorganic salt components such as phosphorus, amines, nitrites, nitrates, and molybdates;
•Compliant with EU RoHS, REACH, and other regulatory requirements.
