The new Stokvis Econo-Air 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 andoptimum energy efficiency.
The new 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.

System Types
The units are designed to provide the primary heat source
across a wide range of applications including:
- Ductless air distribution
- Air Induction systems
- Tempered input ventilation
- Industrial make up air
- Industrial air displacement ventilation
- Pressure ventilation systems
Controls
To maximise the efficiency of operation Stokvis supply a range of fully integrated control packages to suit each application. Units are supplied fully wired and complete with all starters and contactors etc, plus time and temperature control via an integral Trend controller. Optimised start and stop is included as standard and controls are password protected to prevent unauthorised adjustment. For smaller systems a SmartCom control panel may be used instead of the Trend control to provide simple user-friendly control with a comprehensive range of features. The units are also fully compatible with BMS systems and alternative BMS Controls maybe integrated within the control strategy.
