RK Engineering is a globally recognized Thermic Fluid Heater (TFH) manufacturer, supplier, and exporter, delivering advanced closed-loop heating solutions for a wide range of industrial applications. Our Thermic Fluid Heaters (also known as Thermal Oil Heaters) are engineered to provide high-temperature heat—up to 300°C to 400°C—at near-atmospheric pressure. This makes them a safer and more cost-effective alternative to high-pressure steam boilers.

RK Engineering’s Thermic Fluid Heaters are the backbone of various critical industrial processes:
Textiles: Stenters, drying ranges, and polymerizing machines.
Chemicals & Pharma: Heating reactors, distillation columns, and autoclaves.
Food Processing: Edible oil refining, deep frying, and spray drying.
Construction: Asphalt heating and bitumen melting.
Wood & Plywood: Multi-platen hot presses and veneer dryers.
High Temperature at Low Pressure: Our TFH systems achieve process temperatures up to 300°C while maintaining very low pressure. This eliminates the need for expensive high-pressure piping, specialized water treatment, and certified boiler operators.
Precision Helical Coil Design: We use a double-start helical coil design that ensures a large heat transfer area and high fluid velocity. This prevents local overheating and significantly extends the life of the thermic fluid (oil).
Multi-Fuel Versatility: Designed for global markets, our heaters can easily switch between liquid fuels (LDO/HSD), gaseous fuels, or solid fuels like wood and coal. This is particularly beneficial for clients in Kenya and South Africa looking to manage fuel costs effectively.
Fully Automated Safety Suite: Every unit is integrated with interlocked safety controls, including:
Low Oil Flow Switch: Prevents coil burnout.
High Temperature Cut-off: Protects the thermic fluid from degradation.
Flame Failure Sensor: Standard for oil/gas units to ensure safe combustion.
Global Compliance: For our exports to Canada and the USA, we provide systems that adhere to strict safety codes and are configured for 60Hz electrical frequency standards.
The biggest advantage is that a Thermic Fluid Heater provides high-process temperatures (up to 300°C) at near-atmospheric pressure. This eliminates the need for high-pressure piping, water treatment, and a certified boiler attendant, making it safer and more cost-effective.
We manufacture heaters ranging from 100,000 kcal/hr to 5,000,000 kcal/hr, custom-designed for industrial heat load requirements across India, Kenya, and South Africa.
Yes, our systems are multi-fuel compatible. We offer:
This allows clients to choose the most economical fuel based on local availability.
We use a Double/Triple Start Helical Coil made from seamless tubes. This ensures maximum heat transfer and optimal fluid velocity, preventing oil overheating or cracking and extending system life.
Yes. Our Fully Automatic TFH units include a PLC-based control panel with safety features:
Yes. We provide Pan-India installation and commissioning with successful projects in Maharashtra, Tamil Nadu, West Bengal, Punjab, and internationally in Canada, USA, and Africa.
Maintenance includes checking thermic fluid properties (viscosity & flash point), cleaning the burner or grate, and ensuring the expansion tank is moisture-free. We provide manuals and remote support.
Yes. We customize panels for 230V/460V and 60Hz for Canada & USA, and 230V/415V 50Hz for India & Africa, ensuring global compatibility.
