The LES Series steam-fired water heater is a high quality system which provides an economical, high capacity output using steam or hot water as the heating medium. It handles a broad range of capacities and is ideal for most domestic and process hot water applications. The LES Series water heater is designed to fit in tight areas where space is at a premium and is narrow enough to fit through most doorways. Units are offered in vertical or horizontal designs. The LES Series water heater is a completely pre-piped system. All components are sized, mounted and piped prior to shipment and require only hot and cold water lines, connections of steam, condensate and electric. It has digital electronic temperature limit control with LCD readout and is field programmable. This safety system eliminates the possibility of overheating or getting live steam. By utilizing an adjustable electric thermostat, the system is designed to close the main control valve upon an over-temperature condition.
