HWL – heating and circulation
The Alfa Laval HWL – Hot Water Loop is built around a compact, plate-based braced heat exchanger that uses steam to deliver consistent thermal energy. Its construction ensures stable hot water flow and temperatures, which are essential for efficient freshwater generation and engine preheating. The system’s design allows precise temperature control and seamless integration.
Overflowing with optimization
- Energy efficiency – Low electrical power consumption (0.5–12 kW) enabled by bypass piping on the hot water pump and an IE3 motor.
- Modular design – Three configurable scopes of supply allow flexible installation, reduced footprint, and potential CAPEX savings.
- Optimized freshwater generation – Automatic temperature control ensures stable operation and maximizes uptime.
- Reduced engine start-up time – efficient pre-heating eliminates manual adjustments, shortening diesel engine start-up and improving vessel readiness
