FR Series Heat Exchanger Unit Heater

FR Series Heat Exchanger Unit Heater FR Unit Heaters are extra heavy duty (including heavy gauge steel construction) to meet the most demanding service and long life requirements for rugged industrial applications. The FR Series heaters are specifically designed for steam applications that may be subject to freezing conditions, and are of particular value for outdoor applications. Explosion-proof models suitable for hazardous locations are available on custom order. Engineered for ease of maintenance, all parts are easily removed. All fasteners are plated capscrews; no sheet metal screws are used. Heat exchanger cores are of steel construction with tension wound, close fitting aluminium fins. They are resistant to corrosive agents (including hydrogen sulfide). All units are equipped with a narrow-gap, epoxy coated fan guard. Choose from several optional UL listed and/or CSA approved motors with various voltages, phases and frequencies. All FR models have Canadian CRN approvals and are CSA certified for hazardous locations: Class I, Division 1 & 2, Groups C & D; Class II, Division 1 & 2, Groups E, F, & G; Class III, Division 1 & 2; Temperature Code T3B 329 F (165 C) on applicable models only. Epoxy coated 14-gauge steel cabinet construction connections allow for easy core removal. Optional: 2" (50 mm) 300# Flanges* or 2" NPT Male Connections* Choose from several types of motor, general purpose or explosion proof. UL listed and/or CSA approved. 50 or 60 Hz motors. Tension wound close fitting aluminium finned tubes Heresite is a registered trademark of Heresite Protective Coatings Inc. *2" 300# Flanges and 2" NPT Male Connections increase difficulty in core removal.

Heresite coated exchangers and cabinets: contact factory for quote. Louvres and fan blades are also Heresite coated. Contact factory for shipping lead time. Motor designed to be used at rated voltage with tolerances of ±15%. Motor may be marked 230V, but is suitable for 208V operation. 460 1 phase motors are only certifi ed for groups D, F & G. Built in Disconnect only available with CSA certifi ed heaters. Not available on 36 units. 64

FR Single Pass The FR Series is designed for steam applications that may be subject to freezing conditions. Maximum operating pressure is to. This heater is of particular value for outdoor applications, such as on drilling rigs, where boiler failure or crew neglect may result in an accidental freeze-up of the heating system. If accidental freeze-up occurs it is highly recommended the heater be returned to Thermon Heating Systems for inspection. Figure 31 Optional Built-in Disconnect Available Figure 30 The fluid flow is divided among all tubes. This is best suited to steam and high flow rate liquid applications. The Disconnect Switch is engineered for use in the most demanding applications such as drilling rigs, utilidors and compression stations where high vibration, dirt, moisture, fluctuating power and high impact conditions exist. The built-in disconnect switch is available on all FR heaters. Table 34 Performance Data for FR1-12 Entering Steam Refer to the Ruffneck TM HP model for service above 100 psi.
