High-Efficiency, Fully Automated Oil & Gas Steam Generation For Precision Process Industries.
The ISOTEX Evolution represents a new class of oil fired steam boilers — bringing large-system performance and efficiency within reach of smaller industrial operations. Factory-assembled, pre-commissioned, and ready for plug-and-play installation.
ISOTEX Ecotherm Wood Fired Thermic Fluid Heaters combine advanced multi-fuel combustion technology specifically optimised for wood-based fuels with intelligent automation, delivering exceptional thermal efficiency and precise high-temperature heat transfer while minimising emissions.
As a complete turnkey solution — from fuel handling and combustion system to thermic fluid circulation, emission control, and SMARTWIZ IoT monitoring — every Ecotherm unit is factory-engineered for plug-and-play installation, dramatically reducing on-site construction time and costs.
With 4,000+ heater installations globally, up to 74% reduction in site installation costs, and a commitment to EcoVadis sustainability standards, ISOTEX leads industries transitioning to wood-fired thermic fluid heating.
ISOTEX Ecotherm wood fired thermic fluid heaters are available across a comprehensive capacity spectrum — from 4 Lac kCal/hr. to 25 Lac kCal/hr. — to meet diverse industrial high-temperature heating requirements.

Factory-Assembeled Modular Design |
Engineered with advanced multi-fuel combustion systems, the Ecotherm is capable of efficiently burning a wide variety of wood-based fuels to maximise operational efficiency using locally available, cost-effective renewable resources.
Split or whole logs, ideal for large-grate stationary combustion systems
Chipped forestry and mill waste with consistent size for automated feeding
Fine wood particles from sawmills and furniture manufacturing
Compressed high-density pellets for consistent calorific value and clean burn
Offcuts, laminates, MDF dust, and all wood manufacturing waste
| Combustion System Options |
|---|
|
1. Stationary Grate — Ideal for wood logs, larger wood chips, and low-density wood fuels |
|
2. Pinhole Grate — Optimised for fine sawdust, wood shavings, and small particle wood waste |
|
3. Bubbling Bed — Advanced technology for mixed fuels and variable moisture content |
|
4. Dumping Grate — Heavy-duty system for high-moisture, high-ash wood fuels |
The Evolution introduces large-boiler technology — previously reserved for industrial-scale systems — into a compact, factory-assembled package delivering class-leading efficiency for process steam applications.
