How to increase gas pressure
I run a coffee roasting company in Philadelphia. The roaster requires 7" WC to operate at capacity. The city of Phila. guarantees 4.5" which is what we have currently. In the cooler months, gas pressure in the city is increased to 6.5" if we're lucky. Needless to say we can't roast to capacity therefore limiting our output.
I'm surprised how difficult its been trying to find a solution or even an HVAC or plumbing company that is familiar with a solution. Ideally we would have the ability to increase by 3.5"WC.
There were two suggestions, a gas booster or a gas regulator. The gas regulator was suggested by a commercial kitchen equipment contact. I was unsure whether that would increase the max input. Any advice would be much appreciated. I did search the forum but did not find a similar discussion.
