Read MoreOur thermal fluid heaters operate without pressure and water. This avoids the typical problems related to steam heating systems, such as leaks, corrosion, water treatment, etc. Thermal oil heaters require low maintenance. Fuel savings up to 20% compared to steam heating systems. A thermal fluid system consists of a closed circuit with minimum
