Finally, direct electric heating involves electric elements in the gas stream to heat the gas as it flows over the elements. The benefits of direct electric heating are its compact size, and therefore small footprint. While this method does require a reliable source of power onsite, fine and accurate control is possible, which maximises energy efficiency, especially under fluctuating flow rates.
This method also requires no ongoing maintenance, and therefore it has low levels of downtime. Minimal heat is lost during this process, and the method is flexible in location – the unit can be positioned at any angle, and can be indoors and immediately adjacent to the point of consumption to minimise ‘cold slug’ on start up.
Why choose a Grimwood direct electric heater?
Grimwood has the proven capability to design and build direct electric heaters to the highest and most stringent standards in the world. It was the first heater manufacturer in the world to obtain an International Electrotechnical Commission Explosive Certificate of Conformity for these products.
Grimwood can design and build the control system to heat gas to the temperature required depending on the flow rates, and inlet temperatures and pressures without unnecessary and wasteful overheating. The company can deliver the heater with a short lead time, reducing overall project lead time and working capital investment.
