Ecotherm | 4 Lac – 25 Lac kCal/hr | Up to 93% Thermal Efficiency
Compact, smart gas fired thermic fluid heating — precision combustion, maximum efficiency, and full IoT automation in a plug-and-play package.
ISOT Ecotherm Gas Fired Thermic Fluid Heaters represent a breakthrough in compact, high-efficiency gas-fired thermal oil heating — delivering up to 90% thermal efficiency through premium Riello (Italy) gas burner technology, oil-cooled Wet Back reversal design, and advanced IoT automation. The is engineered for industries connected to natural gas pipeline infrastructure seeking maximum efficiency, precision temperature control, and minimum operator intervention.
As a complete compact plug-and-play solution — from burner and heater shell to thermic fluid circulation, air preheating, and SMARTWIZ IoT monitoring — every unit is factory-engineered to minimise on-site installation time and cost. Custom designed for each site, not off-the-shelf catalogue models.
With 3,000+ heater installations globally, single-point project ownership from engineering to commissioning, and engineered for the lowest lifecycle cost — ISOTEX Ecotherm delivers precise temperature control up to 280°C with maximum reliability and minimum downtime.
ISOT Ecotherm thermic fluid heaters are available in six standard capacities from -400 to -2000 — covering 4 Lac to 20 Lac kCal/hr — engineered for compact installation and precise, stable thermic fluid heating for process industries.

ISOT Ecotherm gas fired thermic fluid heaters are engineered with premium Riello (Italy) gas burners — delivering industry-leading combustion efficiency across a range of gaseous fuel options available across India’s pipeline and industrial gas infrastructure.
Natural Gas
Clean pipeline gas at 8,500 kCal/Nm³; maximum combustion efficiency, near-zero SO₂, and lowest CO₂ per kCal of thermic fluid heat output
Compressed Natural Gas
For sites without pipeline access; compressed cylinder or cascade supply with identical combustion performance to PNG
Propane
High-calorific LPG at ~11,900 kCal/kg; compatible with burner with dedicated LPG conversion for areas without natural gas infrastructure
Bio-Methane (Optional)
Renewable gaseous fuel from anaerobic digestion; carbon-neutral thermic fluid heating when using certified bio-methane sources
Dual Fuel (Optional)
Automatic changeover between natural gas and Light Diesel Oil backup; ensures uninterrupted steam supply during gas curtailment or supply interruptions
For customers demanding high efficiency and reliability, ISOT offers Riello Gas Burners (Italy) with multibloc type gas train assembly — a premium burner delivering lower lifetime cost, higher performance, and maximum safety versus local lance burners:
The Ecotherm delivers compact, factory-assembled plug-and-play thermic fluid heating — combining large-system performance in a space-efficient package with advanced heat recovery, intelligent automation, and the lowest lifecycle cost in its class.
