| Page 2 Messrs. Rolls-Royce Ltd. "SK" Refrigeration Thermostat, shown on Drawing No.SK/A/1A could be modified to act as a pressure control, and being smaller and mounted in a metal case, might prove more suitable. If you would like a sample of either of these controls we shall be very pleased to send you one. Yours truly, THE BRITISH THERMOSTAT CO.LTD. W.Martin-Hurst. Director. P.S. The small electric thermostat is intended for mounting in the pocket of one of the water pipes and must not be fitted direct into the water flow. ENCLS: The sample we are sending you is not set for temperature. | ||
