NTI TFT Series Boilers
The NTI Trinity Fire Tube is NTI’s latest high efficiency condensing boiler or combi boiler. With up to a 95.0% AFUE efficiency rating, stainless steel design, nine models from 60,000 to 399,000 Btu/h (17.6 to 116.9 kW), multiple venting options (2″ venting and up to 150′ runs) and a user-friendly ifLEX touchscreen interface, the Fire Tube offers the ultimate combination of efficiency, quality, flexibility and innovation.
Features at a glance:
- Down-fired Fire Tube (Tft): The Tft heat exchanger is ASME certified and uses an innovative down-fire combustor. The combustion tubes also have a dimpled design to optimize heat transfer and increases energy efficiency. The Fire Tube provide generous space for flue gas to pass and significantly reduce the need for cleaning due to the vertical configuration and self-cleaning operation when in condensation mode.
- Stainless steel design: The wet leg combustion chamber enables up to 99% combustion efficiency. The ASME certified heat exchanger is constructed using type 439 stainless steel, making it extremely resistant to corrosion. The Fire Tube design allows water to flow freely around the heating surfaces of the boiler, which significantly reduces pressure drop.
- Efficiencies and Performance: The Tft provides AFUE efficiencies up to 95.0%. NTI was first to develop the totally sealed combustion system, whereby air is not drawn from the surrounding cabinet space.
- Flexibility: The design of the Tft offers more flexibility than any other boiler on the market, with vent runs up to 150′ (45 m), five vent termination options, 2″ venting on some models with plumbing and gas connections on top or bottom of the unit.
- ifLEX Touchscreen: The optional 5.7″ colour touchscreen provides easy programming, control and quick setup with user-friendly screen displays and options.
- ifLEX Interface: Provides easy navigation to all of the controllers parameters and set points. The backlit screen continuously displays system information to ensure safe and efficient operation.
Additional Features:
- Certified internal low water cut-off with test button.
- Fully-modulating combustion system with up to 5:1 turndown.
- Condensate pump receptacle.
- Wall-mount configuration with optional floor stand.
- High-energy spark ignition (with external spark generator).
- 15 year heat exchanger limited warranty.
Controller Features:
- Ultimate controllability with advanced Sola Controller.
- Detailed troubleshooting information (self-diagnostic display).
- Internal “Lead-Lag” capability to connect up to 8 boilers simultaneously.
- Outdoor reset temperature operation increases boiler and system efficiency.
- Ability to control three separate temperature set points.
- Comes standard with Modbus capability.
- Domestic hot water and central heat modulation limiting.
- Ability to control three separate pump loops.
- 4-20 mA heat input for set point or modulation control.
- Freeze protection parameters.
- Warm weather shutdown.
- Contacts for external limits and alarms.
- Compatible with domestic hot water tank sensor.
