Rinnai has launched new products into the commercial gas-fired boiler marketplace with an initial introduction of three condensing models.

The Rinnai Infinity condensing boiler range is available for natural gas and LPG operation, and comes with controls to maximise energy efficiencies through weather compensation technology. The Infinity boiler is also A-rated under the ErP directive.

The Rinnai Infinity condensing boilers come in 50kw, 75kw and 100kw versions. The appliances are accessed from the front, and require minimal space for installation, thus helping to reduce cost and time required on-site. Some of the units also feature a fully removable pivoting heat exchanger and burner for easy inspection and cleaning.

New combustion control technology also gives the units the capability to self-calibrate, avoiding manual setting and automatically adapting to suit the gas quality.

The boilers also offer a range of ancillary options including pressurisation units, manifold pipework assemblies, mounting frames, heating system separators, boiler and water heater combination packs, ancillary control options, external temperature sensor
and advanced boiler controls.

The 50kw, 75kwand 100kw versions all have an efficiency of 93%. The CGB-50 measures 855mm x 440mm x 393mm, while the CGB-75 and CGB-100 both measure 1020mm x 565mm x 548mm.
