Construction
and materials
Three-pass fire-tube scheme:
- ›Cylindrical pressure elements (drum, combustion chamber) and proper distribution of thermal loads ensure super reliability
- ›Monolithic integrity of the structure – a fine-grained structure identical to the base metal is created in the weld zone, eliminating weak points
- ›Zero defect tolerance – each critical weld undergoes validation using radiography and ultrasonic testing methods
- ›Metallurgical compatibility – precise selection of welding materials ensures identical expansion coefficients, eliminating local stresses during thermal cycling
- ›Maintainability – wide inspection hatches and removable panels provide quick access for maintenance.
Fuel flexibility
Operation on natural gas, diesel fuel, and fuel oil;

Frequently asked
What is the advantage of a three-pass design over a two-pass design?
The three-pass design provides three consecutive stages of heat exchange: radiation in the combustion chamber and two convective passes in the flue gas tubes. This allows reducing the flue gas temperature to 150–160°C, increasing efficiency to 96% compared to 92–94% for two-pass counterparts.
What is the actual efficiency of the Trinity boiler on fuel oil?
On fuel oil, the efficiency of the Trinity boiler decreases by 2–3% compared to gas and is 91–93% depending on the type of nozzles and operating mode.
What warranty is provided?
Lifetime warranty on the heat exchanger and main load-bearing elements provided that installation, operation, and water-chemical regime rules are followed.
Can Trinity be used in a cascade with other boilers?
Yes, the control system supports cascade operation with multiple boilers, automatically distributing the load for maximum efficiency.
