Key Features

Its spiral-coil, 3-pass horizontal design allows operation at low flue gas temperatures and high efficiency.

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.

The thermal oil boilers are designed so that the oil velocity inside the coil is of the order of 2,5 – 4 m/s. This preserves the chemical structure of the heat transfer oil and its heat-carrying capacity.

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

Thermal bridges that could arise from the lifting elements and the insulation support elements on the boiler body are prevented, and heat losses are reduced to a minimum.

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

Insulation of the front cover and the rear wall is provided with high-temperature-resistant refractory concrete and ceramic fibre blanket, so that heat loss remains at 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 provides straightforward operation, and remote access from mobile devices makes rapid technical support available from anywhere in the world.

It is supplied with long-lasting insulation that reduces heat losses to a minimum.

Manufacture is in accordance with EN 12952 and the PED 2014/68 CE Directive.

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

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

It is manufactured, in accordance with the requirements of the standards, using high-quality certified boiler plate and seamless cold-drawn steel boiler tube.
