TESY 400L ACM storage tank

TESY 400L V 75 F42P4 is a high-capacity buffer tank designed for storing thermal energy in heating systems, optimized for operation with solid-fuel, pellet, gas and electric boilers, as well as hybrid installations. The model is intended for closed heating systems in private homes, cottages and commercial buildings, ensuring temperature stability and high energy efficiency.

Durable steel tank

The inner tank is made of high-quality steel without coating, providing:

▪️ excellent resistance to hydraulic loads,
▪️ stable operation under all temperature conditions.

High-efficiency INSUTECH insulation

The 50-mm polyurethane foam layer, CFC FREE, significantly reduces heat loss and ensures long-term preservation of the heat-carrier temperature — especially important when used with solid-fuel boilers.

Full temperature control

▪️ built-in external temperature indicator,
▪️ 4 sensor pockets, allowing precise temperature monitoring and weather-compensated control.

Convenient connections

The model features:

▪️ 4 inlets and 5 outlets for flexible integration into complex heating systems,
▪️ a dedicated drain outlet for servicing and water discharge.

Safety system

The standard configuration includes a safety valve that protects the system from excessive pressure.

Compact vertical installation

The narrow cylindrical body allows installation even in confined technical rooms, while the durable PVC casing protects the tank from mechanical damage and simplifies maintenance.
