RTH series heaters are compact, vertical, factory-assembled fired equipment for high temp, closed loop thermal oil process heat applications. Synthetic or mineral based thermal oils having stable properties over a wide temp range of 10 to 300°C are used as heating medium at comparatively [ow operating pressure of 3-4 kg/ cm.
RTH series TF Heaters are fitted with indigenous pre-heated air burners in three-pass combustion system to improve thermal efficiency. These heaters are fitted with standardized components and are quite simple to operate and maintain. A large number of options, such as choice of fuel, addition of standby TF pump, sizing of de-aerator tank are available to users to meet their process needs.
Smaller capacity thermal oil heaters in output range 100 to 300 x 1000 kcal/hr require light fuel oil for combustion for ease of maintenance and operation. These heaters are fitted with single stage burners. Larger capacity TF Heaters are available for operation with light or heavy fuel oil as per customer's choice. Being fully shop-assembled and tested, these heaters are supplied in ready-to-install condition to facilitate quick plant start-up.
