Direct/Indirect Gas Fired Heating & Ventilation Systems

SDF and SIDF SERIES

The Stokvis comprehensive range of gas fired air heaters provides high efficiency combined heating and ventilation solutions across a broad spectrum of industrial and commercial applications. Combined heating and ventilation units ensure precise control, excellent indoor air quality and optimum energy efficiency.

The units are available as either direct fired (SDF) or indirect fired (SIDF) to give complete flexibility for optimum design capability. Both the direct fired and indirect fired range of units are fully CE approved and a comprehensive range of optional equipment can be added to the standard models to allow systems to be tailored to meet the requirements for factories, warehouses and other types of large open space buildings. Where applicable the units are currently Energy Technology Listed by the Carbon Trust to allow qualifying users to claim 100% Enhanced Capital Allowances.

For large open areas the units are available with a wide range of optional air distribution heads to provide ductless air distribution. This is achieved by slightly pressuring the building to ensure very even air distribution both laterally and vertically, thereby eliminating the requirement for extensive distribution duct work and high level de-stratification fan units.

Where duct work is required the units can be supplied with either forward or backward curved fans to allow for duct work resistance up to 2000 pascals thereby making them eminently suitable for use with air induction systems.
