Key Features

The helical-coil, horizontal design allows low flue-gas temperatures and high-efficiency operation.

With heat transfer oils of suitable chemical composition, it can safely reach a high operating temperature such as 300°C  at an operating pressure of 6 bar.

Thermal oil boilers designed so that the oil velocity inside the coil is of the order of 2,5 – 3 m/sn preserve the chemical structure and the heat-carrying capacity of the heat transfer oil.

Pressure losses on the oil side and the gas side are low. The investment cost and the energy consumption of the selected equipment are therefore lower.

Heat bridges that could be created by the lifting and insulation substructure elements on the boiler body are prevented, so heat losses are reduced to a minimum.

It can be manufactured with an open expansion tank or a closed expansion tank with a nitrogen blanket.

Insulation of the front cover and the rear wall is provided with high-temperature refractory concrete and ceramic blanket so that heat loss is kept to a minimum.

On request, design, manufacture and commissioning can be carried out together with an economizer unit. 

High-quality safety equipment provides safe and stable operation.

The PLC-controlled touchscreen control panel makes operation straightforward, and remote access from mobile devices provides fast technical support anywhere in the world.

Delivered with long-life insulation that keeps heat losses to a minimum.

Manufacture in accordance with EN12952 and the PED2014/68 CE directive

Weld inspection on our boilers is carried out by non-destructive testing (NDT) within the scope and ratios set out in EN 12952-6.

Our welded fabrication is carried out by certified welders in accordance with approved WPS and WPQR. MIG-MAG and SMAW welding techniques are applied in manufacture in line with the standards.
