Oil/Gas Fired
These are fully automatic, vertical, coil type thermal fluid heaters. Overall design is robust & reliable with very little maintenance requirement. The liberal furnace volume, higher radiation & convective heat transfer areas provided ensure that the units give excellent performance through complete combustion of fuels & achieving superior thermal efficiency.
Salient features:
- High thermal efficiency of about 88%
- High operating temperatures (up to 370 deg. C) with low system pressure
- Simple circuit, no blow downs, steam traps or condensate return systems necessary when compared with a steam system
- Fully automatic in operation, so no running attention required
- Thermal fluid coil MOC is Seamless Pipes (Sch. 40) confirming to ASTM A 106 Gr. B Standard
- Pre-heated combustion air is an integral part of the design giving superior thermal efficiency
- Liberal furnace volume, high radiant heat transfer area & high convective heat transfer area ensuring superior thermal efficiency & long life of equipment
- Robust & reliable equipment with minimum maintenance for burner, pump & controls
- Expansion & de-aeration tank design is such that it protects thermal fluid from oxidation & provides continuous de-aeration of thermal fluid thereby avoiding pump cavitation
- Three pass design ensuring adequate flue gas residence time which enables achieving superior thermal efficiency
- Fully automatic, oil, gas or dual fuel burners; ON – OFF or with modulating mechanism
Solid Fuel Fired:
These are semi automatic, vertical, coil type thermal fluid heaters with external furnace. Overall design is robust & reliable with very little maintenance requirement. The liberal furnace volume, higher radiation & convective heat transfer areas provided ensure that the units give excellent performance through complete combustion of fuels & achieving superior thermal efficiency.
