NTI Boilers, an Ariston Group company, has introduced upgrades to its current flagship wall hung condensing boilers, the TRX and FTVN. The two condensing wall hung boilers now offer a brand new user interface for an enhanced user experience and easier set-up and troubleshooting for the contractor.

The new technology upgrades allow for easier set-up and troubleshooting on NTI’s TRX Series II and FTVN Series II boilers. Standard features on the boilers include factory-supplied capabilities for two zones, an EXTRATECH stainless steel heat exchanger, and integrated and easily-serviced direct hot water filter and boiler kit. The boilers also offer NTI Net for remote troubleshooting and WiFi capability.

NTI FTVN Condensing Wall Hung Boilers

The TRX model includes a water tube heat exchanger, while the FVTN is a fire tube exchanger. In a water tube exchanger, water flows through tubes arranged inside a furnace filled with gas. In the fire tube model, boilers generate heat by pumping hot gas through tubes submerged in water. Fire tube boilers are generally more compact and can be used in smaller spaces while water tube heat exchangers can handle higher pressures.

Systems can be designed to cascade up to eight boilers. The units also include an LP conversion kit, OD sensor, vent pipe screens, pressure gauge and relief valve.

NTI Net provides the contractor or homeowner with the ability for remote troubleshooting after registering and connecting to the home’s WiFi. The connectivity empowers technicians to remotely view real-time boiler data including settings, status, history and statistics in an easily understandable format.

In addition, setting adjustments are more user-friendly. Technicians can modify the setting and submit, and NTI Net will implement the change while tracking who made the adjustment and when it was made.

GulfClean® Coil Cleaner and Salt Reducer offers the best protection against post-hurricane damage when used on previously treated HVAC systems

Contractors know that hurricanes and severe storms bring more than just wind and rain. They also carry debris, salt, and other corrosive elements that can compromise the performance and lifespan of HVAC systems. For contractors committed to delivering top-quality service and ensuring system longevity, hurricane season is the vital time to promote care and maintenance of HVAC systems.

Even hurricanes that leave minimal structural damage can cause problems behind the scenes. The increase of corrosive elements in the air carried at high wind speeds can cause damage beyond the normal wear and tear to HVAC systems, even those prepped for highly corrosive environments.

A regular maintenance program that includes GulfClean® Coil Cleaner and Salt Reducer products can help reduce corrosion potential, keep systems running efficiently, and delay the need for costly equipment replacements.

The cleaning steps are simple and easy to follow. No special equipment or personal protective equipment (PPE) are required when using GulfClean® cleaning products.

Step 1: GulfClean® Coil Cleaner – Deep Cleaning for Lasting Efficiency

GulfClean® Coil Cleaner is specifically formulated to thoroughly clean HVAC/R systems.

GulfClean® is specifically made for removing accumulated dirt and soil deposits from coils, cabinetry, and components. With its non-acidic, non-caustic, biodegradable formula, this cleaner provides a powerful and environmentally friendly solution. The deep-cleaning foam penetrates stubborn dirt, ensuring coils remain free from harmful buildup, which is essential for maintaining system efficiency and reducing energy costs.

Step 2: Salt Reducer – Protecting Against Corrosive Elements

GulfClean® Salt Reducer is designed for use after the initial cleaning. This concentrated liquid solution is designed to dissolve and remove soluble salts, including chlorides and sulfates, which are both highly corrosive elements.

Like the Coil Cleaner, the Salt Reducer is biodegradable and non-hazardous. Additionally it has no VOCs, is non-flammable, and it does not strip the HVAC/R system of previously applied coatings.

Using the Salt Reducer in conjunction with the Coil Cleaner can help extend the life of corrosion-resistant coatings and ensure the HVAC systems remain reliable for years to come.

Step 3: Restore and Repair with Performance Repair Aerosol™ (PRA™)

After cleaning the system with GulfClean® products, it’s vital to inspect the coils for any chips, scratches, or abrasions in the coating. The next step in your maintenance program should be applying Performance Repair Aerosol™ (PRA™) to restore and protect the integrity of the coating. PRA™ is available in two formulations:

• PRA™ Performance Repair Aerosol – ElectroFin® E-coat for factory-applied ElectroFin® E-coat.
• PRA™ Performance Repair Aerosol – Insitu® ES² Spray Applied Corrosion Coatingfor coils coated with Insitu ES².

These aerosols help maintain coating integrity by protecting against moisture, salt, vibrations, temperature fluctuations, and harsh chemicals. Applying PRA™ after cleaning not only repairs damaged areas but also provides UV protection and enhanced durability, ensuring the HVAC/R unit continues to operate efficiently.

The Best Defense Against Corrosion Begins at Installation

For the best protection, it’s advisable to coat coils either upon or just prior to installation. This proactive step ensures that the coil is shielded from the moment it’s in use. If the system has already been installed without a coating, don’t worry—contractors can still prep the surface and apply Insitu® Spray Applied Coatings to the coils and cabinets for a crucial layer of defense.

GulfClean® Coil Cleaner and Salt Reducer are recommended for cleaning all coated coils as part of a preventative maintenance program and is required to maintain a valid warranty for coils that were coated with either ElectroFin® E-coat or Insitu® Spray Applied Corrosion Coating family of products.

A preventative maintenance program that includes using the coil cleaner and salt reducer will help reduce corrosion potential, reduce energy usage, and help extend equipment replacement timeline by keeping the unit running efficiently.

Preventative Maintenance for Maximum Benefits

GulfClean® Coil Cleaner and Salt Reducer are designed with contractors in mind. Easy to use, requiring no special equipment or PPE, these products offer a straightforward solution for maintaining HVAC systems in top condition. Non-hazardous, non-flammable, and environmentally friendly, GulfClean® products are the reliable choice for ensuring your installations stand the test of time.

In the wake of a hurricane, don’t just clean—protect. Equip your team with GulfClean® Coil Cleaner, Salt Reducer, and Performance Repair Aerosol™ to ensure your HVAC installations perform at their best, no matter what nature throws their way.

“It’s important to let clients know the exact benefits they get from what may seem like “extra” maintenance to the layperson,” says Kristin Kennedy, Business Development Manager, Modine. “Let clients know that GulfClean® Coil Cleaner and Salt Reducer are the essential tools for protecting HVAC/R systems against the harshest conditions.”
