Pirobloc supplies mobile boiler rooms including all necessary components for its operation. Fuel and electricity are only required for use. Our mobile mobile rooms are available for sale or rental and they can be built in 10, 20 or 40 foot containers.

The container is supplied with its ventilation, air conditioning, thermal insulation and lighting. A natural gas detection system is also provided. The expansion tank can be assembled both outdoors and inside the container depending on the available space.

The images show 2 x 1200 kW hot oil heaters assembled in a 40′ container. The boilers are connected in a single circuit so that a total power of 2400kW is available in the plant.

The mobile boiler room is supplied complete with their electric cabinets, circulation pumps, valves, filters, safety devices, flues, expansion tank and degasser, as well as all the components necessary for the operation of a complete boiler room. The entire thermal oil system has already been tested and run both mechanically and electrically in our facilities, so you have an authentic mobile room of complete boilers which need only fuel and electricity to begin operation.

The container is supplied with its corresponding ventilation, air conditioning, thermal insulation and lighting. A natural gas detection system is also provided.

Pirobloc supplies these thermal oil boiler rooms for the needs of each project, taking into account the available fuel, required power and equipment. The expansion tank can be mounted either outside or inside the container depending on the space available. When outside, this tank can be thermally insulated if it is expected to operate at temperatures below 0°C. If inside, the tank is pressurised with nitrogen to create a positive pressure for the suction of the pumps.

Hot oil heaters are operated horizontally, but they can be operated vertically for limited power situations. In the case of the 2-boiler arrangement, these can work simultaneously, so that the total power is the sum of both, or separately, with one boiler in service and the other in reserve. The boilers are equipped with a fire prevention system.

The supply unit limits are the main thermal oil flanges available for connecting the circuit to the devices and the gas inlet valve arranged outside the container.

We offer portable boiler rental services with our own designed and built hot oil heaters.

There are different situations where a temporary rental boiler can be required, such as an unexpected shutdown of the current hot oil heater that stops the production process or a temporary increase in the needs of heating supply.

Not only emergency scenarios can be solved thanks to our mobile rental boilers, they are also optimal for:

  • Scheduled maintenance or repairs of boilers that require a complete stop
  • Plant and process reallocations
  • Unexpected production spikes

In all cases it is paramount to have a backup plan to prevent the production line from stopping for a long time and minimize losses. And in that precise moment is when our portable boiler rooms for rental come in handy.

Quick shipment

We are completely aware of the extreme urgency when a customer needs to rent a mobile boiler room. That’s why we don’t wait until a booking has come through to do the inspection and proper resets.

We do all the work upfront so we can ship the boiler to your premises as fast as possible to help you reduce the losses of the production stop.

Expert Engineer Support

Our expert team of technicians and engineers will work to help you get back on track.

Our portable boiler rooms can be fitted inside 10, 20 or 40 foot containers that can be loaded into a trailer and moved around at will.

It consists of two thermal oil heaters of 1200 kw each, with complete plumbing and electrical installation, proper lighting, gas leakage detection, thermal insulation and full ventilation and heating system also integrated.


The applications that most often benefit of such a setup are:

  • Storage tank heating
  • Extractions
  • Reactor tanks
  • Storage tanks
  • Reheaters
  • Stamping presses
  • Industrial ovens and fryers
  • Natural Gas handling
  • Sleeved tanks
  • Indirect steam generators
  • In line gases and liquids
  • Press moulds
  • Fuel oil and subproducts
  • Rollers
  • Autoclaves ovens
