DSA 1 MINI substation

Flexible, high‑performance district heating solution for any building type

The DSA 1 MINI is a versatile, indirect modular district heating substation designed for use in residential, commercial, and industrial buildings. Engineered to meet high standards in heating, floor heating, and air conditioning, it also offers the option of connecting domestic hot water substations.

With a capacity of up to 150 kW—depending on temperature levels, allowable pressure drop, and local regulations—the DSA 1 MINI complies with more than 90% of the technical connection requirements found in typical district heating networks. Its modular construction allows for easy configuration into a three-circuit substation, while the fully insulated design ensures optimum energy utilization and efficiency.

Features and benefits

High energy efficiency is ensured by an integrated air vent and strainer that keep air bubbles and dirt out of the heat exchanger.
Protected against heat losses by means of insulation shells
Fully insulated unit ensures optimum energy utilization
Leanheat® Monitor and ECL 310 help remote diagnostics for troubleshooting, setting of parameters and preparation of commissioning reports
A compact and lightweight design supports the easy fit into even confined space in the technical rooms.
Low energy loss
Wide capacity of up to 150 kW
