Gas-fired warm air units
Gasflow distributes Multicalor Udara high-efficiency condensing gas-fired warm air units. These systems feature pre-mix burners compatible with natural gas and LPG, offering exceptionally low emissions. Available in six sizes from 10-50kW, they provide both up-flow and downflow models with modulating thermostats for precise temperature control.
Oil-fired heating systems
The company provides spares for legacy Multicalor and Lennox oil-fired products. While new oil-fired units are no longer manufactured, Gasflow offers replacement solutions using MC air handlers connected to oil-fired boilers, maintaining existing ducting systems for seamless integration.
Air handling units
