A used and properly renovated thermal oil boiler may be the best purchase option in some cases, especially when a boiler is needed as soon as possible to avoid interruptions and delays in the production process, or when the customer wants to minimize the investment derived from acquiring a thermal fluid boiler.

In these cases, buying a used boiler may be the most efficient solution.

At Pirobloc we have fully renovated industrial boilers prepared for a second useful life, ready to ship at any time.

Fuel source conversions, as well as other specifications, can be requested.

Fast shipping

We are very aware of the urgency that usually occurs when a customer decides to buy a used boiler. That is why we do not wait until a reservation or purchase has been made for a proper inspection and renewal of the heater. We do all the work in advance to have the boiler ready at all times and to be able to send it to the customer’s premises as soon as possible.

Expert technical support

In addition to commissioning and shipping the boiler, you will receive all the advice and support you require from our team of technicians and engineers so that your production capacity returns to normal without unnecessary delay.
