The method of charging a tank with a gas product up to a desired pressure and temperature without increasing the gas in the tank to a pressure and temperature higher than a desired pressure and temperature, comprising pressurizing the incoming gas to be put into the tank to a pressure equal to or higher than the pressure of the resident gas already in the tank, cooling the incoming gas to a temperature lower than the resident gas, mixing the incoming gas with the resident gas up to the desired pressure such that the pressure and temperature of the combined gas will be increased without increasing the temperature and pressure of the resident gas to a pressure and temperature higher than the desired pressure or temperature.
