Solar systems
SWEP - for heat and hot water
Solar power is the fastest-growing source of renewable energy in the EU. Solar thermal technologies are expected to receive nearly 73 billion USD in investment yearly, up to the year 2050. Nearly half of the solar thermal energy generated by that time will be used to heat buildings and provide process heat for industry.
Hot water and heat
Solar thermal technologies are commonly used in stand-alone applications in residential buildings to produce domestic hot water. SWEP brazed plate heat exchangers (BPHE) are a key component in many applications that harvest solar energy into accumulator tanks, to produce hot tap water and to heat pools. The combination of high capacity in a compact format, efficient heat transfer, and fast response makes our brazed plate heat exchangers the ideal heat exchangers for solar thermal systems.
Maximizes efficiency in solar systems.
Supports carbon-neutral and renewable energy.
Scalable and future-proof.
Challenges without BPHE
In a single-circuit system, contaminants and deposits from the water in the tank may collect on the pipes, eventually impairing the heat transfer properties of the system. Single-circuit systems usually require periodic cleaning to remain functional, leading to unwanted downtime.
A double-circuit system
Using SWEP BPHEs to create a double-circuit system improves heat transfer, dramatically increasing the system’s efficiency. All piping is outside of the tank, which enables precise control of the heat exchange. And because the BPHEs create a fully turbulent flow, they eliminate deposits and buildup, for a maintenance-free heat transfer solution. There is no standing water, so the tank stays clean.
Low-flow variant
A low-flow variant of the double-circuit system makes it possible to generate water both for radiators and also for sanitary water. In systems of this type, the water temperature inside the tank is controlled to create layers of water of different temperatures. Radiator water and tank water for heating the sanitary water can be pulled from the different layers.

CLEAN ENERGY
SWEP components are the key
The heat from the solar field has a working temperature between 73°C and 120°C and is fed directly into the city’s district heating network –with the help of several SWEP B649 Brazed Plate Heat Exchangers.
A solution for every challenge
SWEP offers one of the broadest ranges of BPHEs on the market — from ultra-compact units for low-capacity installations to high-capacity units for large-scale systems.
They offer:
- Compactness
- Increased efficiency
- Gasket-free reliability
- Reduced maintenance costs
- Low installation cost
