Most paraffin heater manufacturers advise that a heater will always briefly give off some odour (1 - 2 minutes) on igniting and extinguishing it. This is because the heater is not yet up to temperature or, conversely, because some unburned gases are released after extinguishing. The use of odourless paraffin (defined in the French norm as having a maximum aromatic hydrocarbon content of 1% m/m) has now reduced the traditional ‘odour problems’ of paraffin heaters to a minimum. With Toyotomi Premium Heating Liquids, however, we go a step further. Toyotomi Plus has an aromatic hydrocarbon content of less than 0.1% m/m, making it practically odour-free in use. Toyotomi Clear is a GTL synthetic fuel derived from natural gas. Its purity means it is completely free of aromatic hydrocarbons (less than 0.007% m/m). Both products guarantee optimal functioning of mobile heaters, especially as regards odour emission.
