Gas-fired air heaters for large spaces

Stokvis Energy Systems, air heater, space heating

Econo-Air gas-fired air heaters from Stokvis Energy Systems are designed for large open spaces such as factories, warehouses, sports halls, conference centres, exhibition centres, arenas and swimming pools. Little or no ductwork is needed, and the space is pressurised to ensure a clean atmosphere. Ventilation and cooling can be provided during the summer.

To achieve the best solution for large open spaces, careful consideration has to be given to a variety of factors. An industrial warehouse with most of the activity involving semi-automatic fork-lift trucks carrying out picking operations is very different to an exhibition space such as ExCel.

Not only must the heat load be calculated accurately, but air circulation must also be modelled.

The requirements for ventilation and replacement air must also be considered. If dust is generated, extraction will be part of the production process.

Heated replacement air is therefore required to maintain comfort. If replacement air is not provided, the extract system will perform inefficiently, and a negative pressure can be created — leading to cold air being drawn in through leakage in the building envelope.

For new installations, the supply of heated air can often provide adequate ventilation without additional extract units. If additional extract is needed, it can be integrated into the same unit to facilitate both input and exhaust flows — with the option of heat recovery from the exhaust air stream.

The Econo-Air range includes direct-fired and indirect-fired models. Fully modulating burners down to 20:1 give accurate temperature control and high efficiency. Output ranges form 15 to 900 kW for indirect units and 30 to 1200 kW for direct-fired units.
