In 2025, Baron von Olsträd continued to extol the virtues of our C911-P pressure switches, by parodying old ads we found online. Here is our annual retrospective, where we unveil the ads that inspired us. In the olden days, children couldn’t wait to slip on their pajamas and play with fire. Thank goodness we’ve come Read More

Comments Off on Pulse-fire 101 — Pulse-fire Pitfalls
Through our discussions regarding equipment selection, you’ve learned that pulse-fire requires solenoid valves with extremely high operating cycles, burners that light reliably, and some method of impulse control. Through dozens of installations, our technicians have encountered and overcome a number of additional pitfalls, which can derail even the best planned system. Oversized Burners A common Read More

Comments Off on Pulse-fire 101 – Pulse-fire Equipment
Not all combustion equipment is suitable for pulse-firing. Some of the key equipment requirements for a successful pulse-fire installation include: operating cycles in excess of one million, capability of three cycles per minute, and repeatability. Solenoid Valve Operating Cycles In traditional, modulating systems, gas solenoids open during start-up and remain open during furnace operation. Unless Read More

Comments Off on Pulse-fire 101 – An Introduction to Pulse-fire Combustion Systems
Improve your bottom line, lower your operating costs, increase your product quality, and do your part to reduce greenhouse gases. How? By using pulse-fire to transform your industrial furnace! What is Pulse-fire? More than anything else, pulse-fire is a method of introducing heat into a gas-fired furnace. Traditional modulating systems use valves to control the Read More
Ignition Transformer FAQ

Comments Off on Ignition Transformer FAQ
An ignition transformer is a device used for direct spark ignition in combustion systems. Reliable, repeatable direct-spark ignition requires a high-energy spark — and the ignition transformer is what we use to generate the high voltage we need to create that spark. A typical supply in the USA is 120 volts, but we need to send Read More
