Prominent Features
• Capability to operate with low flue gas temperatures and high efficiency thanks to its 3-pass and horizontal design with coiled tubes.
• With heat transfer oils of suitable chemical content, can safely reach a high operating temperature such as 300oC with 6 bar operating pressure.
• Thermal oil heaters, designed in such a way that the velocity of the oil in the coil is in the range of 2.5 – 4 m / sec, ensures the protection of the chemical structure and heat carrying capacity of the heat transfer oil.
• Oil and gas side pressure losses are low. Thus, the investment cost and energy consumption of the selected equipment is lower.
• By obstructing the thermal bridges that may occur while lifting or by insulation substructure materials on the heater body, thermal losses are minimized.
• Can be supplied with open or nitrogen cushioned expansion tank.
• Front cover and back wall insulation are provided with high heat resistant refractory concrete and ceramic blanket with minimum heat loss.
• Upon request, it can be designed, manufactured and commissioned with the economizer unit.
• Provides safe and stable operation thanks to high quality safety equipment.
• Thanks to PLC controlled touch screen control panel, quick technical support can be obtained from anywhere in the world with easy operation and remote access from mobile devices.
• Shipped with long-lasting insulation that minimizes heat losses.
• Production in accordance with EN12952 and PED2014/68 CE directives
• Welding check of our heaters is carried out with non-destructive testing (NDT) within the scope and ratios specified in EN 12952-6.
• Our welded productions are carried out by certified welders according to approved WPS and WPQRs. MIG-MAG and SMAW welding techniques are applied during production in accordance with the norms.
• They are manufactured by using high quality, certified boiler sheet and seamless boiler tubes in accordance with standard requirements.
