| X4300. He/Lid.{A. J. Lidsey}3/KT. Sept. 1st, 1932. Messrs Clayton Dewandre Co, Ltd. Titanic Works, Lincoln. Dear Sirs, Clayton Heating Equipment. In reply to your letter of the 30 th. inst; we have pleasure in informing you that we have completed preliminary tests on the sample Interior Heating Equipment. The results of our tests so far indicate that the system is quite satisfactory. Electrically the apparatus appears perfectly good and is commendably silent; the heater, we think, is sufficiently effective for the largest closed private car. We have not used the valve in the engine top water pipe, as we find we can get ample circulation by connecting the heater across the engine water pump. Our cars are fitted with thermostatically operated radiator shutters which maintain the water temperature at 80°C, so that any further control is unnecessary, provided that we can obtain circulation through the heater; this as stated above is satisfactory. We have not used your type of connection to the heater, we prefer a nut and nipple to your method of swaging over the copper pipe. We are shortly sending the car, to which the apparatus is fitted, to our Sales Dept, for a demonstration of this heater, and will advise you later of any further developments. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
