GermanyControls & Actuators

Siemens Building Technologies (formerly Landis & Staefa, acquired 1998) produces the combustion-management and flame-safety hardware that sits at the heart of most European and Asian commercial burner installations. The full Siemens Combustion Controls catalog is available — LGB/LME/LMG burner-management relays, SQM/SQN servo actuators, AGM/QRA flame detectors, RWF/RLU controllers, and the SKP/VGD gas-valve families — with field-engineering support for retrofits onto legacy burner racks (FBR, Beckett, Riello, Weishaupt).

Tentang Siemens

Siemens Building Technologies (formerly Landis & Staefa, acquired 1998) produces the combustion-management and flame-safety hardware that sits at the heart of most European and Asian commercial burner installations. The full Siemens Combustion Controls catalog is available — LGB/LME/LMG burner-management relays, SQM/SQN servo actuators, AGM/QRA flame detectors, RWF/RLU controllers, and the SKP/VGD gas-valve families — with field-engineering support for retrofits onto legacy burner racks (FBR, Beckett, Riello, Weishaupt).

The highest-volume product is the LME-series integrated burner management, which replaces older LGK/LAE relay families still in service on pre-2010 installations. Swapping an LGK21 for an LME73 typically halves cold-start times and unlocks ModBus integration for building-management systems. The LME21, LME39, LME41, LME73, and the matching SQM33/SQN70 servo actuator range are available for order.

Siemens actuators and gas-valve bodies are specified on major commercial and industrial installations globally — district cooling, inflight catering, hospital steam plant, semiconductor fab process heat, container-terminal reefer-deck heating. Field engineers handle the full Siemens commissioning workflow: configure parameters via the Siemens ACS450 service tool, verify safety times against applicable national gas-burner codes, and log the commissioning sheet into the customer's building-management system history.

Aplikasi Umum

  • District cooling plants — LME73 + RWF55 for condenser-water modulation
  • Inflight catering and food-processing steam boilers — LMG22 with SQN90 air-fuel cross-damper
  • Hospital steam-plant redundancy — LME41 with QRA2 UV flame detection for dual-fuel boilers
  • Semiconductor fab process heat — LME23 and SKP55 gas valves on hot-oil heater skids
  • Container-terminal reefer-deck heating — LMG22 retrofit onto legacy burner racks

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang Siemens dari 3G Electric.

Are Siemens Combustion Controls products available?

Yes. We carry the Siemens combustion-controls portfolio (Landis & Staefa heritage) — LME/LGB burner controls, SQM/SQN actuators, flame detectors, and SKP gas-valve bodies.

Can I upgrade an older Siemens LGK21 controller to the current LME series?

Yes. LGK-to-LME retrofits are among our most common commissioning jobs. LME73 and LME41 drop into the same DIN rail, pick up the existing wiring harness, and re-use the existing SQM servo without replacement. Typical cutover is around 2 hours on-site including configuration via ACS450.

What is the lead time for Siemens LME and RWF controllers?

LME21, LME39, LME41, and LME73 are typically available on shorter lead times. RWF55 controllers and the full SQM/SQN actuator range have a factory lead time on request.

Do you provide on-site Siemens commissioning?

Yes. Our field engineers carry the Siemens ACS450 and ACS450.2 service tools, handle parameter configuration, safety-time verification against applicable national codes, and log commissioning sheets into the customer's building-management system.

Can you supply Siemens ATEX / zone-classified controllers?

Yes — Siemens produces zone-2 variants of the LMG and SQN ranges for petrochemical use. We supply these on approved project quotes with factory lead time on request.

Do you supply Siemens LME and LMV controllers?

Yes, we stock Siemens LME, LMO, and LMV series burner controls in Singapore.
