Should you be requiring steam for your process then this is also made possible with these waste oil heaters, simply by changing the copper coil from a 12.7mm diameter to a 3/8 or 10mm copper coil. These will produce a constant stream of steam. The system must be an open loop without being able to be close it off. A pressure relief valve would be required should you need to close the loop.
The waste oil heater would be the same as the 45 kg heaters and product steam basically for free.
This heater price is $1490.00 nzd
Add $50.00 for the relief valve and fittings
