Superior life cycle cost for district energy systems.

Compact, reliable and efficient heating and/or cooling of homes, offices, schools and hospitals, with a low carbon footprint. Proven in millions of installations worldwide. Why wait? There are only advantages to gain.

District energy describes the process through which to efficiently heat or cool buildings through an underground network of pipes and substations. In much of northern Europe, district heating and cooling networks have been a mainstream option since the oil crisis of the early 1970s.

The effectiveness and efficiency of heating and cooling networks is entirely dependent on heat exchangers which hydraulically separate the circuits. This enables them to withstand high design pressure and allows the components to manage the heavy load.

In many cases, traditional solutions like Shell and Tube heat exchangers (S&T) or gasketed plate heat exchangers (PHE) have been used but these take up a lot of space and require regular maintenance.

Moving forward, SWEP has pioneered the development of the gasket-free brazed plate heat exchanger (BPHE) which has several clear advantages. The BPHE maximizes the most efficient transfer of energy and the lifecycle cost over a period of 15-20 years can often be reduced compared with gasket-plate solutions.

Here are 4 key benefits you get when you specify SWEP BPHEs.

  • Less maintenance mean lower lifecycle costs SWEP BPHEs deliver efficiency and reliability throughout their lifecycle. Gasket-free BPHEs mean minimal maintenance cost, no spare parts and reduced downtime for cleaning.
  • More for less - SWEP BPHEs are lightweight and compact, designed to handle demanding district energy applications with close temperature approaches and high operating pressures. Compared to gasked heat exchangers, a BPHE-based system will perform same heat transfer with reduced footprint.
  • Flexible and modular - Designed as smaller units, BPHEs allow you to expand your system if required. If you previously needed extra capacity for redundancy purposes only, you can now have a heat exchanger solution that perfectly matches your needs.
  • Compact for easy installation The compactness of a brazed plate heat exchanger allows for quick installations, whether a retrofit or a new system. Delivered in compact units, a BPHE can normally be moved using a regular hand truck and fits into most elevators.

  • District Heating & Cooling
    Efficient heating and cooling of homes and buildings

    District heating

    Many cities around the world with cooler climates are benefiting from district energy systems delivered through heat networks. The technology for this is relatively simple: hot water supplied by one or several centralized plants, is transported through a piping system to provide heating where it is needed - homes, offices, hospitals schools and factories. District heating systems provide a number of benefits that include lower carbon footprint and low lifecycle cost.

    District cooling

    In cities with hotter climates, district energy systems are used to deliver cooling. As with district heating, the technology to deliver this is relatively simple. Cooling energy in the form of cold water is produced centrally and transported to customers via a closed circuit. And again as with district heating, this can be achieved with decreased carbon footprint, cost efficiently and reliably.

  • Tap Water Station
    There are two main categories of systems:
    Centralized - meaning a central heating unit that is typically installed in the basement of larger buildings and used to heat water distributed to all users in the building.
    De-centralized - meaning a heat exchanger is installed in each building across a development, so that each apartment or office has its own individual supply.
