A distinctive feature of Pegaz heating modules is the use of liquid fuel or gas. The release of these devices is limited to ten standard sizes. In total, they cover the range of air performance from 3,000 m³/hour to 65,000 m³/hour. They can be used in all climate systems that can be installed in closed rooms with normal dustiness. It is also possible to work outside the building or in OLIMP roof units. Pegaz modular units are indispensable for use in rooms without power supply. In the absence of a gas pipeline, a gas tank or other fuel tank can be used. In addition to being used as an element of systems, the Pegaz modular heater can be used as an individual heater.
