About Combutech
Combutech manufactures combustion control and flame detection equipment for industrial burner systems, heating applications, and process automation. The product range focuses on pressure monitoring, flame sensing, and control logic units designed for integration into oil and gas burner installations across manufacturing, power generation, and facility management sectors. Combutech's pressure switches operate across the 2–500 mbar range with ±15% allowable deviation and IP54 protection, suitable for both low-pressure monitoring and process-critical applications. The company supplies UV flame detection cells rated to 10,000+ operating hours with IP65 sealing and recovery times of 20 microseconds, paired with flame relay modules that manage up to 10 simultaneous detectors. Control units such as the COMBU1s operate at 230 V ±15% with adjustable purge timing (1–250 seconds) and integrated safety delays, allowing plant engineers to configure startup sequences and load management without external PLC logic. All process connections follow standard industrial threading (1/4" female and 3/4" gas ports), and electrical connectors conform to DIN-EN 175301-803 and DIN43650 standards for straightforward panel integration. 3G Electric maintains stock of Combutech's core pressure-switch and flame-detection families from its Singapore warehouse, supporting same-day fulfillment and technical specification requests for maintenance and retrofit applications across the Asia-Pacific region and global markets.
Frequently asked questions
Common questions about Combutech from 3G Electric.
What pressure ranges does the Combutech COMBUP series cover?
Combutech offers five pressure-switch models spanning 2–500 mbar: COMBUP10 (2–10 mbar), COMBUP50 (5–50 mbar), COMBUP150 (5–150 mbar), COMBUP500 (100–500 mbar), and custom variants. All are rated to ±15% allowable deviation with 1.5× Pmax 1-minute test pressure. Standard process connection is 1/4" female thread with IP54 protection and 3-pin DIN electrical connectors.
How long do Combutech UV detection cells operate before replacement?
Combutech UV1 and UV1p detection cells are rated >10,000 operating hours at 50°C under 1 mA discharge current and 10% duty cycle. Recovery time is 20 microseconds (UV1p) to 20 seconds (UV1), with spectral response in the 185–260 nm ultraviolet band. Both feature IP65 sealing and DIN43650 3-pole connectors for burner flame monitoring.
What is the maximum load capacity of the Combutech COMBU1s control unit?
The COMBU1s combustion control box is rated 3 A @ 230 VAC (cosϕ = 0.4) output load with 5×20 mm quick-blow 3.15 A fuse protection. It accepts 230 V ±15% input at 50/60 Hz frequency, with adjustable purge time between 1 and 250 seconds and pre-ignition delay of 500 ms for safe burner startup sequencing.
Can multiple UV detectors be connected to a single Combutech flame relay?
Yes. The Combutech CF1 flame relay module supports up to 10 UV detectors on a single line, with nominal current draw of 3 A maximum and minimum triggering current of 10 mA @ 5 V. It is rated 1 A @ 250 VAC and 1 A @ 30 VDC, housed in polycarbonate UL94-V0 material for industrial panel mounting.
What electrical protection standards do Combutech combustion switches meet?
Combutech pressure switches and flame-detection modules use DIN-EN 175301-803 (3-pin industrial connector) or DIN43650 (3-pole euro connector) electrical connectors. Housing materials include polycarbonate UL94-V0 for flame relays and sealed stainless-steel or plastic bodies rated IP54 to IP65 depending on application.
Are Combutech pressure switches suitable for low-pressure burner applications?
Yes. The COMBUP10 (2–10 mbar) and COMBUP50 (5–50 mbar) models are designed for low-pressure monitoring in atmospheric and forced-draft burners. All COMBUP switches feature factory pre-set points adjustable within their rated ranges, 1/4" female thread process ports, and operate reliably at the lower pressure bands typical of fan-assist and natural-draft heating systems.
