Storage tank TESY 50L EV50 40 for heat pump

TESY EV50 40 buffer tank (50 liters) is a compact, energy-efficient storage vessel designed to ensure stable operation of heat pumps and cooling systems. The model is engineered to smooth out temperature fluctuations, increase system efficiency and extend compressor lifespan. Its smart construction makes it suitable for both residential and commercial applications, ensuring uniform distribution of the heat carrier and optimizing equipment on/off cycles.

Key features of the model

High-efficiency 50 mm insulation

A dense polyurethane layer reduces heat loss, maintains stable temperature and lowers electricity consumption.

4 inlets and 4 outlets G 1¼"

Multiple ports provide connection flexibility and high flow capacity in heating and cooling circuits.

Energy efficiency class B

The construction is optimized to minimize heat loss and reduce operating costs.

Stratification brackets

These create temperature layers inside the tank, improving heat-exchange efficiency.

Anti-condensation design

The body is adapted for cooling systems; an optional anti-condensation kit prevents moisture buildup.

Drain G 1½" and air vent G ¾"

Simplify maintenance and increase system durability.

Support for electric heating element

Ability to install an electric heater (TEN) — a key advantage for hybrid heating setups.

Enamel-coated steel tank

Provides long-term corrosion protection.
