Discover the ultimate solution for industrial heating with the Ruffneck™ HP Series Heat Exchanger Unit Heaters, designed to withstand the toughest environments while delivering exceptional performance. Experience unparalleled durability and efficiency with features tailored to meet your specific heating needs.

Ruffneck™ HP Series Heat Exchanger 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, such as space heating and liquid cooling. The HP Series heaters are suitable for a wide range of heating fluids including steam, hot water, glycol, oil, etc. Explosion-proof models suitable for hazardous locations are available on a 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 wounds and close-fitting aluminum 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 HP 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).

The HP Series is designed for pressures up to 400 psi (on select models). These units have semicircular headers that can withstand high operating pressures for steam or liquid service. The HP series is available in single‑pass and multi‑pass configurations. Single‑pass units are desirable for high-flow rate liquid service requiring a low-pressure drop or for steam applications. Multi‑pass units are intended for liquid service only. They are baffled in the top and bottom headers such that the heat transfer liquid will flow through groups of tubes in series within the core. This causes the liquid to travel a longer distance at a higher velocity, thereby increasing the heat transfer rate due to increased turbulence. Units with the greatest number of tube‑side passes will always have the highest heat output, but will also have the highest pressure drop. Depending on the application, an HP model in a one, three, five, or seven-pass core configuration may be recommended.
