Greenheck Introduces GreenJet Axial Transfer Fans for Car Park Applications

Greenheck’s new GreenJet® axial transfer fans provide ventilation for ductless underground parking applications.

 In a ductless system, the garage still uses a main supply and exhaust duct, but the installation of an axial transfer fan eliminates the need for ductwork throughout the parking areas. This approach maintains safe conditions by providing fresh air dilution within the space. Installation costs are reduced by eliminating the need for ductwork in the garage area, and the low profile design helps to lower garage construction costs by reducing floor-to- floor heights.

The GreenJet Model GJX is a robust direct drive axial fan that requires minimal maintenance. It utilizes an efficient airfoil propeller designed to move high volumes of air through a smaller diameter fan. GreenJet fans are available with inlet and outlet attenuation to keep sound levels low. Model GJX is AMCA Licensed for Air Performance and UL/cUL Listed for Electrical (UL/cUL-705) and Power Ventilators for Smoke Control.

Greenheck is the worldwide leader in manufacturing and distributing air movement, conditioning and control equipment.


Car Park Fans

As cars are parked within an underground parking structure, carbon monoxide (CO) and other noxious fumes are emitted into the atmosphere.

There is a need for an efficient ventilation system that can remove these toxins, circulate fresh air into the car park, and assist firefighters in the case of a fire emergency. The GreenJet series includes a range of performances to accommodate your needs for parking garage ventilation.

Ductless designs use transfer fans to dilute and remove contaminants and control the smoke. When installed on the ceiling, they move the air towards the exhaust area, by effectively creating a continuous flow, avoiding the creation of stagnant zones where air gets trapped.


High Performance Axial Transfer Fan

Improved Exhaust Effectiveness with GreenJet


Simplified Design: Eliminates the need and expense of designing a duct system.
Lower Construction Cost: GreenJet fans require less height against the ceiling than a ducted system. This means the required height of each level is less, reducing excavation and lowering overall construction cost.
Lower Installation Cost: A typical GreenJet system results in less installation time.
Improved Operational Costs: Eliminating ductwork reduces the system static pressure and allows for smaller supply and exhaust fans to run using less power. The use of third-party exhaust sensors allows for demand-based ventilation.
Reduced Maintenance: GreenJet fans are more accessible for maintenance than traditional systems, and eliminate duct cleaning.
Enhanced Safety: GreenJet fans are more efficient at removing noxious fumes and clearing smoke, resulting in a safer environment.


Nest Learning Thermostat

The Nest Learning Thermostat works with 95% of 24V heating and cooling systems.

IEC is pleased to announce the Nest Learning Thermostat with 3-speed capability is now available through the IEC Aftermarket Parts Department. The Nest Learning Thermostat is more beautiful than ever, with a thinner, sleeker design and a bigger, crisper display.


IEC offers the largest selection of products in the industry


As the leader in hydronic fan coils, IEC offers the largest selection of products in the industry.

Our offering covers the full spectrum of horizontal and vertical systems, modular hi-rise, and belt-driven fan coils, as well as innovative designs created specifically for hotel rooms, hospital rooms, dormitories, apartments, and condominiums.  Our ongoing commitment to research and development means that we are bringing you the best products available, such as our innovative RestoraMod, which cuts replacement time for hotel room fan coils by over half.  In addition, IEC offers unique products with energy-saving technology such as our EC motors, and features such as foil face and closed cell insulation for an even higher level of IEQ (Indoor Environmental Quality).


Maintain, restore, or replace? IEC has answers.


Do you have an aging facility, combined with limited budgets? Many building owners, faced with the same situation, address the same question relative to their HVAC system – do I replace, repair or refurbish?

At IEC, we understand these questions and have developed a range of aftermarket solutions that provide the best refurbishment and remodeling solutions for building owners and their HVAC contractors. Today’s leading building management teams know that in many cases restoring their existing fan coils, rather than replacing them, can result in significant cost savings, and much less downtime and disruption. Replacing an entire fan coil unit may involve drywall, surface finishing, fire-proofing, and cleanup expense. However, with refurbishment, just a few components can be replaced to upgrade the unit and its performance.
