Calpak Mark TT2 Thermosyphonic Controller

The Calpak Mark TT2 Thermosyphonic Controller is a comprehensive control solution designed for thermosyphonic hot water systems — typically paired with solar water heaters or hybrid tanks that rely on natural circulation (thermosiphon) without a mechanical pump. It combines automatic temperature control, advanced safety mechanisms, and system durability components to ensure reliable hot water delivery at preset times and temperatures.

Features & Benefits

• Automatic Thermostat Control : Guarantees hot water at preset times for maximum convenience and energy efficiency.
• Complete Safety Protection : Includes pressure reducers and temperature & pressure relief valves to prevent overheating and over-pressurisation.
• Stainless Steel (Inox) Flanges : Corrosion-resistant heating elements and heat exchangers ensure long service life.
• Polyphosphate Filter System : Reduces scaling and mineral build-up, protecting the tank and improving performance.
• External Magnesium Anode : Provides enhanced anti-corrosion protection for extended system durability.
• Integrated Expansion Vessel : Absorbs pressure changes during heating, preventing system stress and leaks.
• Secure Compression Fittings : Enables reliable, leak-free installation with standard plumbing connections.

Use Cases

• Residential Solar Water Heating Systems : Ensures hot water is ready at preset times for morning and evening household use.
• Off-Grid & Hybrid Homes : Works efficiently with solar thermosyphonic systems, reducing reliance on grid electricity or generators.
