Hot water boiler type series HWE
The compact hot water boiler of type series HWE were designed to heat large water volumes in a constant controlled flow. The hot water boiler are suited as consumers for mains stabilisation, as autonomous calorifiers without local emission sources, and as a means to secure the district heating supply. Your advantage: The hot water boiler can be directly integrated into the district heating mains. The area of application comprises all control range products: Secondary control range (SRL), minute reserve (MRL)
Properties
- Infinitely variable output control, combination of variability in stages or infinitely in case of large outputs
- Boiler generates directly heated supply water
- Large heat transfer surfaces, minute surface load
- No special requirements on water quality
- Direct integration into direct heating mains
- No separate heat exchanger required
- Unsupervised operation: available according to EN 12953 (TRD 604) (control interval 72 hours) (Bob 72)
- High redundancy due a variety of tubular heaters
- Robust and maintenance-free design
Your advantages
- Economic and technical safety, due to proven quality
- No large conversion measures generally required due to compact design
- Low investment costs, fast amortisation
- High efficiency (> 99%)
- High availability (Optional: additional reserved power)
- Ad-hoc use, due to short response times
Power Range: 1 at 5 MW
Electrical connection: 690 V / 50 Hz / 3 ph
Calculation pressure: up to 30 bar

Manufacturing standards
Pressure Equipment Directive (PED) 97/23 / EC,
EN 12953, EN 13445, AD-2000
Functional principle
In the calorifier of the hot-water generator, water is heated directly by a number of electrical tubular heaters. Inside the tubular heater, the electrical energy is converted into heat by the heating resistor.
