## Long description

The Biawar Wymiennik Mega W-E-150.81 with coil (model 16412) is a compact coil-type heat exchanger designed for integration in central heating and hot water systems. It transfers thermal energy between primary and secondary circuits using an internal coil, enabling indirect domestic hot water production or controlled heat exchange in boiler and tank systems. The unit is intended for installations where space-efficient coil heat transfer and reliable separation of fluids between circuits are required.
Advantages
The internal coil design provides efficient thermal transfer while keeping the primary and secondary fluids hydraulically separated, reducing the risk of contamination. Its compact footprint allows installation in existing boiler rooms or inside storage tanks without major modifications. Constructed from materials suitable for heating applications, the exchanger supports stable operation within common system parameters and facilitates retrofits or integration with different heat sources.
Suitable for
 Indirect domestic hot water production in heating systems
 Heat exchange between primary boiler circuit and secondary loop
 Integration into hot water storage tanks or compact boiler rooms
 System retrofits where a coil-type exchanger is required
Key specifications
 Coil-type internal heat transfer element for hydraulic separation of circuits
 Designed for integration with boilers, storage tanks and closed heating loops
 Compact construction suitable for confined installation spaces
 Material and finish compatible with standard heating system fluids
How to use
Install the heat exchanger according to the hydraulic scheme of the installation: connect the primary (heat source) circuit to the coil inlet and outlet, and connect the secondary circuit to the exchanger shell connections. Ensure correct flow direction, appropriate pipe sizing and secure fittings to prevent leaks. Commission the system by gradually bringing it up to operating temperature and checking for proper heat transfer, pressure stability and absence of leaks. Follow local codes and the installer’s guidelines for pressure testing, venting and water treatment.
Usage recommendations
To ensure long service life and efficient performance, use corrosion-inhibited water appropriate for closed heating systems, install suitable strainers and air vents, and carry out periodic inspections for scale, sediment and tightness. When integrating with different heat sources or tanks, verify compatibility of operating temperatures and pressures before commissioning.
