The RLT-CDC Copper Double Coil Storage Tank is a high-efficiency hot water storage system designed for advanced multi-energy applications. It features a durable enamel-lined interior, robust pressure-rated construction, and dual copper coil heat exchangers that maximize heat transfer and system performance. With superior insulation for heat retention and enhanced corrosion protection, it ensures long-lasting, energy-efficient operation across a wide range of heating systems.

Product

Parameter RVG Industrial Enamel Standard Enamel
Adhesion Performance Utilizes a state-of-the-art automated enameling process to achieve Grade 1 adhesion, ensuring a strong and permanent bond between the enamel and steel substrate. Typically achieves Grade 3 adhesion, resulting in comparatively weaker bonding performance.
Enamel Layer Uniformity Engineered for consistent and uniform enamel thickness, delivering a smooth, refined surface finish with superior structural integrity. Displays inconsistent enamel thickness with common surface imperfections such as orange peel texture, scaling, and conductive pinholes.
Resistance to Boiling Water Loss Validated through rigorous TÜV-certified testing, demonstrating extremely low boiling water weight loss (as low as 0.55 g/m²), ensuring exceptional durability. Meets only basic industry testing standards, offering limited resistance to long-term thermal and water exposure.
Service Life Features an industrial-grade enamel liner with advanced anti-corrosion properties, extending service life by up to 5 years beyond conventional alternatives. Conventional enamel liners are prone to early-stage degradation, often developing defects within 2–3 years of operation.

 

Features of liner

1.Precision Spray Technology: Advanced spraying techniques ensure superior adhesion, forming a seamless and durable bond between the steel substrate and enamel coating for long-term performance.

2.Triple-Layer Protective Lining: Engineered with a high-performance three-layer system comprising an adhesion layer, reinforcement layer, and an ultra-clean, industrial-grade anti-corrosive enamel glaze, delivering exceptional resistance against corrosion and wear.

3.Premium Grade Steel: Manufactured using Baosteel BTC340R specialized steel plates, ensuring enhanced structural strength, durability, and reliability under demanding conditions.

4.High Pressure Fatigue Resistance: Rigorously tested to withstand up to 300,000 impulse pressure cycles, ensuring consistent performance and long operational life.

5.Advanced Welding Technology: Fabricated using a professional submerged arc welding (SAW) process, ensuring high integrity joints, superior strength, and long term leak-proof performance.
