Benefits of Hybrid Heating & Cooling

Energy efficient heating and cooling for a wide range of commercial applications

All in one unit – Heating, Cooling & Ventilation (HCV)

HCV units can be effectively set up with a range of options including easy to assemble adjustable galvanised roof stands, alternative location return air and specialised screens for areas with specific conditions such as bushfire prone areas.  HCV units can be installed on the roof or at ground level or even within plantrooms.

The modular system allows a large range of heating and cooling combinations or stand-alone options for the specifier and customer.

  • from 29 to 700 kW heating or 1,800 – 25,000 L/s airflow in cooling mode

This allows contractors and specifying engineers to tackle the challenges of delivering on the requirements of any HVAC project.

Hydrogen Ready

AIRAH gas heaters are hydrogen-ready for a renewable and sustainable future

The renewable gas future is here

Hydrogen, when used as a fuel, produces no carbon emissions and can be blended with or even replace the natural gas that is supplied to homes and businesses around Australia. Gas distributors are aiming to fully decarbonise their distribution networks by 2040 as a stretch target, with the Australian Gas Infrastructure Group aiming to deliver at least 10% renewable gas across its distribution networks by 2030 and 100% by no later than 2050.

Seeley International has been working with leading industry authorities to ensure that our gas heating products are “hydrogen-ready”, meaning they will perform at their best using hydrogen blends to provide the same warmth and comfort that thousands of Australian businesses expect and have been experiencing every winter with AIRAH gas heaters.
