Heaters
Howden heaters are designed to raise the temperature of air, or any other process gas, with the aim of either increasing the thermal efficiency of a process, initiating a chemical reaction or drying of a product.

Our in-house design capability allows for much flexibility in the solution that we offer. We will custom build a heater designed specifically for the process requirements and customer specification.

Howden offers a turn-key service including engineering, procurement, on site construction and erection, project management and commissioning, encompassing the engineering disciplines of civil, mechanical, control and instrumentation and electrical.

Detailed specifications
The Howden heater will be built to accommodate your specific temperature and flow rate requirements. Special care will be taken when selecting the material of construction to insure extended operating life in harsh operating conditions.

The thermal efficiency of the heater is dependent on the final design and can be optimised by taking advantage of both radiant and convective heat transfer mechanisms.

The heater can be designed such that there is direct contact between the heat source and the process gas, or if required, a closed circuit system can be designed to insure no contamination of the process gas.

The heat source can be electrical heating elements or burners which can be fired on gas, diesel, heavy fuel oil, etc. All burner operated systems are designed in compliance with the SANS 329 specification to insure the safety of the equipment and operators.
