We got your RFQ for the 1000L/h unit, and the OH1000 is pretty much the standerd choice for medium-scale and heating work—it runs on just water and electricity, so no gas cylinders to worry about.

It pulls 5V at 60A, single phase, with a max working presure of 2 kg/cm², and what that means in practice is you're looking at a steady 1000 liters per hour output for jobs that'd normally eat through acetylene fast.

Water consumption is about 1.8 L/h automatically fed, and when you add the flame modifier at 0.2 L/h manually, the flame gets hot enough for glass polishing or jewelry brazing—though it's not really suited for heavy welding on thick steel sections.
The unit is 540x500x670 mm and weighs 80 kg, and you'll need 200 mm of clearance around it for ventilation; we usually have stock but confirm lead time if you're ordering more than 50 units or so.

One thing buyers don't always ask about is that manual control mode means you're adjusting teh flame by hand, which is fine for most setups but not ideal if you need automated precision—common with smaller shops though.

Anyway, for the 220V version (check your local votage), our company can ship within 20 days or so, COA and HPLC data included with each unit.
Our standard MOQ is 1 unit for stock models, but we can negotiate for larger orders if you need bulk pricing.
Usually 15-20 working days after order confirmation, depending on current production load.
Yes, we can provide CE, ISO, and test reports. Just let us know which documents you need, and we'll include them with the shipment.
It works on 220V or 110V single phase, but note the rated power is 5V 60A, so you'll need a compatible power supply—not a standard wall socket for the output side.
Store it in a dry, well-ventilated area with at least 200 mm clearance on all sides, away from direct sunlight and moisture.
