Ventilation / Heating System

Sigma Ventilation/Heating System is pre-engineered for stability. Furthermore, it provides the desired climate conditions inside the dome. The system is completely automatically-controlled.

1.Variable Pressure Control–frequency converter reducing overall energy costs

2.DFS–Double Fan System; modular fan operation, increased reliability

3.Improved modulating system (saving up to 35%)

4.High-efficiency heat exchanger

5.High efficiency condensing units (up to 105% efficiency)

6.Automatic programmable control (wind, snow and pressure sensors)

7.lent operation - a radial fan of low noise, silencers

8.heating options: natural gas, LPG, oil, hot water or steam, electricity, heat pump, biomass, combined source.

Emergency Backup System

Reliability and safety are the most important features of Sigma air domes and the constant power supply is a critical item that must not be left to chance.

Auto start function and automatic shutdown

12-24 h autonomy, which can be extended up to 100h

Equipped with tested and reliable engines of well-known manufacturers which have a service network practically all over the world

Anchoring

Every structure needs a solid foundation to keep it anchored and secure. With the Sigma advanced anchorage system, air loss around the base perimeter is significantly reduced, providing savings on inflation.

1.Perfect airtightness

2.Powerful fixation

3.Suitable for extreme weather conditions

4.For permanent or seasonal use of the dome

5.Durable hot galvanized steel and maintenance free
