Leslie Controls LES Series Packaged, Steam-fired Water Heater
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.
The LES Series water heater is designed to handle a broad range of capacities and is ideal for most domestic and process hot water applications.
Compact, Easy to Install 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 vertical requiring only 7½ square feet (0.7 m2), the horizontal only 15 square feet (1.4 m2).
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. Efficient Design LES Series water heaters respond instantly to fluctuating demand, delivering accuracy to ±5°F (±2.8°C) of preset temperature and a maximum hot water output of 330 GPM (1,249 LPM). The tank of the water heater is insulated with two inches of foam which helps retain heat and reduce operating costs. Safety Engineered The LES Series water heater 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. If an over-temperature condition is detected, the electric thermostat sends a signal to the valve, thereby closing it. An optional double safety system is available. This system features a double solenoid system which, in addition to closing the main valve, opens a solenoid valve at the top of the vessel allowing the over heated water to drain out of the vessel. Both the standard safety system and the double-solenoid system require a 120 volt, 5 amp circuit to operate.
Quality The LES Series water heater is designed with quality in mind. ASME Code stamping and registration offers the assurance of quality controlled construction. The packaged water heater is constructed with a virtually rustproof 316L stainless steel tank and pre-threaded pipe connections. A 20 gauge steel jacket protects the insulation and its hammertone enamel painted exterior provides a neat, finished appearance.
