Our products : Combustion & Control Combustion & Control Krom Schroder Combustion & Control Products Kromschroder and Custom Electric: Partners In Technology Custom Electric is an authorized distributor of Krom Schroder products, and providesa broad range of combustion and control systems for gas-fired equipment. Air/Gas Ratio Regulators Maintains constant gas/air ratio to optimize combustion; internal low fire by-pass available; wide regulating range; inlet pressures up to 3 psig; outlet pressures up to 48 in. WC; for continuous, high/low, and pre-heated applications. Gas Solenoid Valves For natural gas, LPG, and air applications; sizes from 1/8 to 4 in.; AC power supply; DC coil system. Pressure Reducing Regulators Low and medium pressure regulators; inlet pressures to 60 psig; outlet pressures to 100 in. WC; sizes from 1/2 to 4 in. Control Valves For Air And Gear Motors Ideal for setting air flow ratios; some models available with position indicators; low leakage. Motors: Actuated via three step, continuous, or two point signal; infinitely adjustable switching cams standard for precise setting. Burner Controls – Safeguards, Detectors, Sensors Unites functionally interrelated components such as ignition transformer, gas solenoid valve, and flame supervision devices; flame detection with flame rod or UV detector; options for restart or immediate fault lock-out following flame failure. Ignition Transformers For ignition of gas burners; compact dimensions for cabinet or wall mounting; ignition and burner monitoring with common electrode. Pressure Switches For Gas And Air Available for sensing gas pressure or air pressure; sensing range of 0.2 in. WC to 7 psi for gas; sensing range of 0.08 in. WC to 20 in. WC for air. Valve Proving Controls Checks both shut-off valves for leakage; prevents burner from starting if leak is detected; testing before or after burner run; separate pressure switch not required; extremely safe due to self-monitoring electronics. Ball Valves, Filters, Orifice Assemblies, Pressure Gauges Ball valves with maximum operating pressures to 60 psi; filters with maximum inlet pressures from 15 to 60 psi for gas and air; orifice assemblies allow precise flow of natural gas and air; pressure gauge assemblies with push to check cock. Turbine Meters For measurement of flow and volume (to 35000 CFH); analog or LCD display heat; turndown range up to 20:1; compact design with universal mounting position. Complete Gas Trains And Gas Burners Pre-packaged gas trains for gas inlet pressures of 5 psi and lower and gas inlet pressures greater than 5 psi. Burner heads provide a normal flame shape, long, soft flame shape, or a very short, flat flame. Burner heads can be used with natural gas, town gas, and LPG.
