INTER-TECH
The Inter-Tech model boilers are intended for water open system central heating installations with both gravitational and forced water circulation. The installation must be secured according to currently valid and detailed national provisions. Steel Inter-Tech model boilers with automatic fuel supply system are intended for work in central heating installations and domestic hot water preparation installations in housing development buildings, i.e. single family houses, commercial pavilions, garages, and utility buildings. Boilers constitute a steel structure welded from certified 5 mm thick boiler sheets that ensure a long-term use. The controller handles CH and DHW pumps, as well as auxiliary pump and valve actuator. There is a possibility to connect room regulator and SafeIT (control via Internet) module.
