Fire Tube heat exchanger

One of the major advantages of NESTA Chrome Fire Tube heat exchanger is the self-cleaning feature. The unique design and orientation of the heat exchanger allows the condensate to run down the inside of the heat exchanger tubes and cleans any possible traces of combustion residue. This function allows the boiler to maintain maximum efficiency throughout the lifespan, leading to reduced running costs and maintenance for the end user.

Key Features & Benefits

Stainless steel heat exchanger
Self-cleaning flue ways
Internal circuit piping in welded stainless steel
Low pressure drop
Compact dimensions
Reduced maintenance
Very quiet operation
Low NOx

Evolved ECU flexibility

Intuitive for both the user and the engineer complete with weather compensation functionality. The integrated AIC Electronic Control Unit (ECU) can manage up to 3 direct or mixed circuits and one circuit for DHW production via an external storage cylinder with anti-legionella function when installed with additional control accessories. It can also manage up to 6 boilers in cascade and has connectivity for regulation and remote control.

Cascade

The Nesta Chrome boiler is designed to work in cascade, up to a maximum of 6 boilers and a maximum output of 900 kW.

Our cascade system is easy to install thanks to the prefabricated stainless steel hydraulic kits and accessories manufactured by AIC.

The perfect solution for medium and large installations where the heating demand fluctuates according to building usage.
