| THE STEAM FITTINGS CO. Ltd., West Drayton, Mdx. “SAMSON” Automatic Temperature Regulators Are applicable to Regulation of Room temperatures, within plus-minus one degree, when heated by radiators, hot water or steam pipe, hot air, or gas fires. They are particularly useful for Public Buildings, Schools, Hospitals, Laboratories, etc. A Special type is made to operate Electric heaters. TECHNICAL APPLICATION. Calorifiers, feed water heaters, condensors, steam cookers, dye vats, kiers, hot liquor tanks and fermenting vessels in breweries, glue heaters, Pasteurisers, sterilisers, medicated baths, etc. Warming ovens, baking ovens, incubators, grain, vegetable, textile, leather and paper driers, timber drying and seasoning plant, etc. They are also applicable for cooling plant of every description. “SAMSON” TEMPERATURE REGULATOR CONTROLLING AIR DAMPER. “SAMSON” TEMPERATURE REGULATOR CONTROLLING GAS FIRE. THE STEAM FITTINGS CO. Ltd., West Drayton, Mdx. “SAMSON” Automatic Temperature Regulators FOR ROOMS AND LIQUIDS (Patented). ROOM Type. LIQUID Type. THESE REGULATORS meet the demand for a reliable device for maintaining constant temperature of atmosphere or liquids heated by air, hot water or steam. They can operate steam, gas, oil or water valves, or air dampers, and can be adapted for the operation of Electric Switches. Each Thermostat forms a self-contained unit with the valve or valves or damper which it controls. No outside source of energy, such as water, compressed air or electric power is needed. This has the advantage that it is impossible for all Regulators to be put out of action by a failure of a centralised source of operating energy. The energy required is supplied by the rapid expansion and contraction of a liquid highly sensitive against temperature variations—that is to say, by direct liquid pressure—applied to a frictionless piston. As the temperature rises the valve is gradually closed, so that after-heating effects, when the valve is at last completely shut, are less than with devices suddenly shutting off the fully opened valve at the desired temperature. | ||
