CRUXVertical thermal oil boiler (thermal oil heater) Boilte Crux
Boilte Crux – high-temperature vertical thermal oil boiler (thermal oil heater)
Boilte Crux is a vertical thermal oil boiler (thermal oil heater), a specialized unit for the safe and efficient heating of liquid organic heat transfer fluid to temperatures up to 300°C at a working pressure in the system not exceeding 10 bar. Crux is a radical solution to the space shortage problem: the vertical design allows for a space saving of up to 40% of the production area compared to horizontal counterparts.

Why choose CRUX
Vertical design – space saving up to 40%
Installation in confined spaces without expanding the boiler room.
300°C at a pressure of <10 bar
Safer and more economical than steam systems.
Lifetime warranty
On the coil heat exchanger. No time limit.
Protection of thermal oil
Flow rate control, emergency cooling, hydrodynamic modeling.
Three-pass gas system
Maximum heat extraction, efficiency up to 90%.
Natural convection
When the pumps stop, the oil rises – an additional safety margin.
Construction
and materials
Vertical coil combustion chamber:
- ›Vertical orientation of the coil – optimal use of room height, minimal occupied area
- ›Coil heat exchanger made of seamless tubes – manufactured from special heat-resistant steel designed for long-term operation at high operating temperatures and cyclic loads
- ›Forced circulation – powerful pumps ensure the required flow rate of oil through the coil, eliminating local overheating and thermal cracking of the oil – the main cause of its aging
- ›Three-pass flue gas system – gases pass sequentially through three passes, maximizing heat transfer, ensuring an efficiency of up to 90% even at high temperatures
- ›Sealed circuit – a completely closed heating and oil circulation system eliminates contact with air oxygen, preventing oxidation.
Service & warranty
The Crux boilers are covered by a lifetime manufacturer's warranty on the coil heat exchanger, provided that installation, operation, and operating mode rules are followed. The actual service life under proper operation exceeds 15–20 years.
Each boiler is accompanied by a complete set of technical documentation: passport, installation and operation manual, non-destructive testing reports, hydraulic testing reports, compliance certificates.
Serial model
parameters
For non-standard requirements, custom builds to the customer's drawings are available.
*Lifetime warranty applies during the declared design service life of the boiler and is subject to BOILTE Warranty Terms.
Heavy, crude and waste fuels are subject to fuel-specific warranty terms.

Frequently asked
What is the main advantage of the vertical design of Crux?
The vertical design saves up to 40% of the production area compared to horizontal counterparts. This allows the boiler to be installed in confined spaces, in existing boiler rooms without expanding openings and reconstructing the building. Additionally, the vertical design utilizes natural convection: when the pumps stop, hot oil rises, providing an additional safety margin.
What is the economic efficiency compared to steam?
Heat losses in the steam system amount to 15–20% due to the latent heat of vaporization and blowdowns. In the thermal oil system Crux – only 3–5%. Energy efficiency is higher by 15–25%.
What warranty is provided?
Lifetime warranty on the coil heat exchanger provided that the installation, operation, and operating modes are followed.
How is the thermal oil protected from degradation?
Precise flow rate control using sensors and adjustable pumps prevents stagnation and overheating. Multi-point temperature measurement in real-time transmits data to the controller. Emergency cooling circuits automatically activate backup cooling in case of power failure or pump shutdown.
