Flue gas connection
- Flue gas conduit D80, fire resistance class B1 plastic pipe made of PP, permitted as a flue gas conduit for condensing heat generators with flue gas temperature up to 120 °C
- Flue gas temperature limited to max. 90 °C on thermostat
- Safety thermal cut-out set to 100 °C
- Recommended flue gas counter-pressure: 500 Pa; maximum flue gas counter pressure 800 Pa
- Flue gas flow rate: 69 m3/h i.N. in normal state is equivalent to 89 m3/h at TFlue gas = 80 °C
- Maximum condensate quantity: 8,9 l/h
Flue gas heat exchanger
- Thermodynamically optimised cast aluminium-silicon heat exchanger
- Integrated catalytic converter
Utilisation of calorific value
- The flue gas temperature is a maximum of 15 K above the corresponding return temperature
- Calorific value used at a return temperature of about 55 °C and above
Engine
- Ford industrial gas engine
- Model: MSG 425
- 4-cylinder Otto engine, water-cooled
- Displacement: 2.489 cm³
Coupling
Maintenance-free, plug-in, flexible metal/plastic coupling to compensate for radial, axial and angular misalignment.
Generator
- Four-pole asynchronous machine for parallel operation on the public grid
- Manufacturer: Weier GmbH
- Model: DASGM 160/L 4 water-cooled
- 3 × 400 V, 50 Hz
- Start-up current: about 60 A
- Rated current: 30,0 A
- cos φ: 0,77 (inductive)
- Rated power: 20 kW
- Rated speed: 1.538 min-1
Compensation
Due to the requirements in German code of practice VDE-AR-N 4105:2018-11, operating own generating systems without reactive power compensation is only permitted in exceptional cases. A cos cos φ of 0.95 is achieved with the standard fixed compensation.
Controller
- Industrial computer with powerful MPC555 microcontroller, 32-bit power PC with FPU
- Fully automatic operating control
- Remote monitoring/operation via LAN or optional mobile data connection
- Interfaces to higher-level DDC controls: digital and analogue inputs and outputs; optional CAN bus, RK512, Modbus, LON bus, Profibus DP, BACnet/IP, IEC 104, Profinet
Housing
- Sturdy, easily removable, frameless full thermoacoustic enclosure
- Machine unit on four Asonator steel springs
- Optional base on two vibration dampers to isolate noise
Noise emissions
- Mean sound pressure level at 1 m distance ≤ 53,1 dB (A) as per DIN 45635-11
- Mean sound pressure level (standard equipment) at 1 m distance (45°) to chimney outlet ≤ 41,1 dB (A) as per DIN 45635-11
